Introduction

We all feel special when we get into the topic of  Space and Alien. We always look at the Night sky and always wonder what’s there beyond the large Universe.

Is there God, Aliens or Ghost world? We always feel something new when we see how vast our Universe is.

Physicist Enrico Fermi also felt something the same too. He kept asking himself, where is everybody? That’s how Fermi’s paradox appeared today.

What is Fermi’s Paradox about Alien and it’s solution ?

Fermi wasn’t the first person to ask such question about Alien intelligence. But his paradox is well known around the world as the Fermi paradox.

It is typically defined like, if the Universe is deep vast. The probability of intelligent alien life seems almost definite.

But since the Universe is also 14 billion years old, its seems to afford plenty of time for these beings to make themselves know to human. So, well where is everybody?

Night sky seems vast and we can see about 2500 stars roughly 100 millionth of stars are in our Milky way Galaxy.

And almost all of them are less than 1,000 light years away from us or 1% of the diameter of Milky Way.

There are 250 billion ± 150 billion stars in our galaxy and there are roughly 2 trillion galaxies  in the observable universe.

total number of star in observable universe

Observable Universe

Altogether that comes out typically one power 24 total star in the observable universe. Which means that, for every grain of sand on every beach on Earth there are 10,000 stars out there.

Belief on Hypothesis about Alien contact

According to Zoo, The Zoo hypothesis : the assumed behavior and existence of technically advanced life and the reasons they refrain from contacting Earth. 

The hypothesis is that alien life intentionally avoids communication with Earth, and one of its main explanation is that it does so to allow for natural evolution.

For example aliens might choose to allow contact once the human species has passed certain technological, political, or ethical standards.

They might refrain contact until humans force contact to them, possibly by sending a spacecraft to the planets they colonize.

An alien society with advanced technologies may conclude that direct contact with them may result out risk.

Conclusion

Actually they are trying to find humans. And some of them have already did, but they are scared of human despite of their development.

They have to overcome the truth of them and us. Maybe they are still roaming somewhere in the Universe.

You Should Know : This Artificial Moon launch can break human imagination

Have you ever wonder why airplane can’t go to outer space like rocket does ? Before starting this topics first let me make you clear about basic definition of space.

Space; that region which is more than 100 kilometer above from the surface of earth. Density of oxygen got decreased order as the height goes increasing from the earth surface.

Check out : Australia doesn’t exist and people who live there are actors paid by NASA – Claimed by Flat Earth Society.

Then obviously there will not be oxygen in space. To work airplane it’s engine most performs well & we know all engine are thermal. which means they need oxygen to generate energy to initiate engine of airplane.

At first when plane is in the earth’s atmospheric region it will works fine. But when it goes up & up then amount of oxygen molecules will goes down. which will result to the error of working efficiency of jet engine.

That’s why airplane cannot goes to the space. And if you got confused how rocket engine works even there is no oxygen in space. Checkout this links to clear your confusion.

:- This is the most discussed topics among science lover; ‘ If God never exist then who create this universe & millions of organism’? God ;the most greatest opponent of today’s science & scientist and whose existence is still unsolved from us.


There are hundreds of artificial evidence to deny the existence of God. On the other hand peoples of earth followed more than 4200 religion.

Then there is one question mark, in front of those who are related to at least one religion among these numerous religion. ” Does Your God exist, Or you’re following your religion whose God never exist ?”.

In this article limitedscience is going to make you clear upon these topics. Don’t skip any single words because each & every words will make sense to get complete knowledge about this question.

Creation of Entire universe

Can you figure out how long is 13.4 Billion years time periods. This vast time periods is that greatest past where millions of changes happened in this universe.

One great explosion from empty space happened named as ‘The Big Bang’. Ans stars, planets, gaseous masses, meteor , black hole & many more cosmos masses get formed from every tiny pieces.

One of the pieces was our sun, which eventually get strikes with another cosmos masses & break numerous pieces. Some got eject out from it’s gravitational field.

Meanwhile some got attached inside it’s gravitational field & create 8 planets,millions of meteor, gaseous masses, meteorites space belt collectively named as ‘The Solar System’.

Let’s Get into the Earth

4.6 Billions years have passed when our planet earth was formed by solar sun strikes as mentioned above. To get into this suitable condition earth have face millions of up & down changes.

At initial condition temperature of earth was nearly equal to the temperature of sun. Because it was also one of the part of sun. Due to the high temperature, continuous vapor originated from vaporization of oxygen, hydrogen & other gases molecules.

Which leads to the formation of dense clouds, and result to the continuous rain for few hundred thousands of years. Which leads to the formation of large water masses like lake,river,ocean & seas.

Due to the high specific heat capacity of water temperature of earth start to decreased. After few millions of years temperature of earth got balanced to the normal temperature.

Origination of life

Marine water were rich on organic substances. Methane,Nitrogen, Hydrogen,Oxygen & Carbon were in soluble form in oceanic water. By taking organic substances as nutrition & soluble gases as cell functioning units most primitive bacterial unicellular organism were formed.

Via cell division via mitosis & meiosis most primitive cellular organism grown into advanced unicellular organism.

While some change into microscopic multicellular organism like paramecium & algae.

During survival for fittest & struggle for existence some organism change their survival location; like some become aquatic & some become terrestrial.

Conclusion

Through these billions of years, organism were formed from organic substances.In ocean By the help of cell division growth & change in physical appearance occurs.

As accordance to the laws of evolution; survival for fittest & struggle for existence many species got changed physically. In this way millions of organism got created to make this earth full of diversity.

Imagine neutron stars so fast they devour everything in their path, clouds that smell of fruits, an enormous gathering of galaxies and Louis Armstrong music in space? These are some of the unbelievable things you can find in our cosmos. The universe is enormous and full of secrets and there are still millions of things to be discovered. Today we’ll tell you about 10 unbelievable things that are currently in space.

  • In 1988, when scientists found a pulsar that seemed to devour a nearby star, they named it the Black Widow Pulsar. A pulsar of this kind is a neutron star that rotates at about 600 times per second and emits electromagnetic radiation.
  • You could fit 1.3 million Earths inside the sun. The sun accounts for 99.86% of the mass of the solar system. And do you remember the 2 largest planets in our solar system? Jupiter and Saturn make up most of the remaining 0.14%.
  • Sagittarius B2 contains vast amounts of a chemical compound called ethyl formate. When you mix ethanol with formic acid, you get ethyl formate, which is an ester. Esters are known as “smell molecules,” and they provide strong floral, fruit, and wine smells.
  • Saturn has always stood out with its characteristic rings. Scientists believed that only planets could have rings until they encountered the Rings of Chariklo in 2013.
  • The Himiko Cloud existed at a time when the universe was just 800 million years old. The universe is 13.8 billion years old right now, so the Himiko Cloud comes from a time when the universe was just a baby!
  • Black holes represent a very tight and dense area of space where gravity is so strong that not even light can get out once it goes in. Black holes range from small, as large as an atom, to supermassive.
  • El Gordo, or “The Fat One” in Spanish, is the name of the most enormous grouping of galaxies ever found in the distant universe.
  • The “Golden Record” includes greetings in more than 50 languages, images of human anatomy, diverse sounds, and nearly 90 minutes of music.
  • Rogue planets end up alone in the cosmos when they are kicked out, or ejected, from their planetary systems. CF was the closest planet found at the time, but more have shown up since.
  • The center of the Milky Way holds a supermassive black hole called Sagittarius A*. It is located 26,000 light-years from Earth and has a mass 4 million times bigger than our sun.

Moon, The second option after mars for the selective planet/satellite for human colonization far from earth. Scientist from all over the world are giving their best to shifting our homo species far from earth to the another cosmos body, some prefer creating it’s own atmosphere & some prefer the concept of Terra-forming for making our Moon suitable for living life.

But, what should we do for making our mission of shifting human colony successful, Humm ? Ain’t a hardest imagination about that greatest mission. Okay don’t worry, we’re going to predict some things to do for making Moon suitable for life.

  • Oxygen obviously become the main & one and only basic things needed for living life. So, first of all moon should have provide unlimited amount of oxygen. For the supply of unlimited amount of oxygen strong atmosphere is needed to stop oxygen molecule escaping out from moon. So, creating it’s own atmosphere becomes the first things we should do for human colonization on Moon.
  • Terraform of Moon can be another ways of spread human species in cosmos. Terraform is that process in which close construction are built & tree are planted inside the monument, artificial oxygen are manufactured & supplied inside & eventually slowly atmosphere are being build. This idea seems to be quite weird Still this will takes many years to get succeed but in my perspective this ways can be the most possible ways for human colonization.
  • Before planning to start colony on Moon, first analyze the obstacle for reaching the Moon from earth. Trillions of dollar of money will needed, risk of spacecraft accident, scarcity of food,oxygen & water will be the first obstacle for this journey.
  • WHO WILL LEAVE THIS BEAUTIFUL PLANET ? : Every person express his desired to visit moon, if you ask someone will you visit moon then obviously everyone will answer ‘Yeah we will’ but have you ever think what if you ask someone, ” Will you travel to moon permanently for living there, till your last breath ?”, there will be awkward silence of fear of loosing beloved person, friends, relatives & this heaven called as Earth. I am sure no one will be ready.

We hope you guys like our article, THANKS for your precious time.

All of you must have read on your lower classes about the definition of time ? And may have answered ‘Time is the difference between two events’. Is this enough points to define the definition of this vast question “TIME”? Not at all, then what’s the exact definition of ‘Time’?.

Time, the most mysterious stuff that is still un-defined by this modern era of science. The indefinite continued progress of existence and events in the past, present, and future regarded as a whole is the simplicity definition of time. Whenever we discuss about time we can’t miss the fourth(4th) dimension, space time & space curvature.

For better understanding first of all let you know about space time, space curvature & 4th dimension. space time directly related to the dimensions;
In physics, space time is any mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Space time diagrams can be used to visualize relativistic effects such as why different observers perceive where and when events occur differently.

Diagram : Space Time

Let us make you more understanding;

Physics is the only science that explicitly studies time, but even physicists agree that time is one of the most difficult properties of our universe to understand. Even in the most modern and complex physical models, though, time is usually considered to be an ontologically “basic” or primary concept, and not made up of, or dependent on, anything else.

In the sciences generally, time is usually defined by its measurement it is simply what a clock reads. Physics in particular often requires extreme levels of precision in time measurement, which has led to the requirement that time be considered an infinitely divisible linear continuum, and not quantized (i.e. composed of discrete and indivisible units). With modern atomic time standards like TAI and UTC and ultra-precise atomic clocks, time can now be measured accurate to about 10−15 seconds, which corresponds to about 1 second error in approximately 30 million years.

But several different conceptions and applications of time have been explored over the centuries in different areas of physics, and we will look at some of these in this articles.

In non-relativistic or classical physics, the concept of time generally used is that of  absolute time (also called Newtonian time after its most famous proponent), time which is independent of any perceiver, progresses at a consistent pace for everyone everywhere throughout the universe, and is essentially imperceptible and mathematical in nature. This accords with most people’s everyday experience of how time flows.

However, since the advent of relativity in the early 20th Century, relativitistic time has become the normal within physics. This takes into account phenomena such as time dilation for fast-moving objects, gravitational time dilation for objects caught in extreme gravitational fields, and the important idea that time is really just one element of four-dimensional space-time.

Relativity also allows for, at least in theory, the prospect of time travel, and there are several scenarios which allow for the theoretical basis of travel in time. There are even theoretical faster-than-light time-travelling particles like tachyons and neutrinos. However, the concept of time travel also brings with it a number of paradoxes, and its likelihood and physical practicality is questioned by many physicists.

Quantum mechanics revolutionized physics in the first half of the 20th Century and it still represents the most complete and accurate model of the universe we have. Time is perhaps not as central a concept in quantum theory as it is in classical physics, and there is really no such thing as “quantum time” as such. For example, time does not appear to be divided up into discrete quanta as are most other aspects of reality. However, the different interpretations of quantum theory (e.g. the Copenhagen interpretation, the many worlds interpretation, etc) do have some potentially important implications for our understanding of time.

Most physicists agree that time had a beginning, and that it is measured from, and indeed came into being with, The Big Bang some 13.8 billion years ago. Whether, how and when time might end in the future is a more open question, depending on different notions of the ultimate fate of the universe and other mind-bending concepts like the multiverse.

The so-called arrow of time refers to the one-way direction or asymmetry of time, which leads to the way we instinctively perceive time as moving forwards from the fixed and immutable past, though the present, towards the unknown and unfixed future. This idea has it roots in physics, particularly in the Second Law of Thermodynamics, although other, often related, arrows of time have also been identified.

Black Holes

A black hole is a region of space time exhibiting such strong gravitational effects that nothing, not even particles and electromagnetic radiation such as light can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform space time to form a black hole.

The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed.[8] In many ways a black hole acts like an ideal black body, as it reflects no light.

Moreover, quantum field theory in curved space time predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

How are Black Holes identified?

As the universe is too big and dark, we can barely see the black holes because of the matching colors of both bodies. But scientists had found a way to spot a black hole by following the massive shadow cast by it in many heavenly bodies.

Event Horizon Telescope(EHT) Project

The Event Horizon Telescope is a project to create a large telescope array consisting of a global network of radio telescopes and combining data from several very-long-baseline interferometry stations around the Earth. The aim is to observe the immediate environment of the super massive black hole Sagittarius A* at the center of the Milky Way, as well as the even larger black hole in the center of the super giant elliptical galaxy Messier 87, with angular resolution comparable to the black hole’s event horizon.

It previously, on 10th April, 2019 was successful to capture the photo of a super massive Black Hole, located at the center of Messier 87 Galaxy, commonly known as M87. The Black Hole located there is about 6.5 Billion times massive than our Sun of solar system. The black hole was given the name Pōwehi, meaning “embellished dark source of unending creation” in Hawaiian.

Messier 87(M87)

Messier 87(M87) is a super giant elliptical galaxy in the constellation Virgo. One of the most massive galaxies in the local Universe. It has a large population of globular clusters about 12,000 compared with the 150–200 orbiting the Milky Way and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at relativistic speed. It is one of the brightest radio sources in the sky, and a popular target for both amateur and professional astronomers.

The French astronomer Charles Messier discovered M87 in 1781, and cataloged it as a nebulous feature while searching for objects that would otherwise confuse comet hunters. M87 is located about 16.4 million parsecs (53 million light-years) from Earth and is the second-brightest galaxy within the northern Virgo Cluster, having many satellite galaxies. Unlike a disk-shaped spiral galaxy, M87 has no distinctive dust lanes. Instead, it has an almost featureless, ellipsoidal shape typical of most giant elliptical galaxies, diminishing in luminosity with distance from the center. Forming around one-sixth of its mass, M87’s stars have a nearly spherically symmetric distribution. Their population density decreases with increasing distance from the core. It has an active super massive black hole at its core, which forms the primary component of an active galactic nucleus. The black hole was imaged in 2017 by the Event Horizon Telescope, with a final, processed image released on 10 April 2019.

The galaxy is a strong source of multi wavelength radiation, particularly radio waves. Its galactic envelope extends to a radius of about 150 kilo-parsecs (490 thousand light-years), where it is truncated possibly by an encounter with another galaxy. Its interstellar medium consists of diffuse gas enriched by elements emitted from evolved stars.

Super Massive Black Hole

A super massive black hole is the largest type of black hole, containing a mass of the order of hundreds of thousands, to billions of times, the mass of the Sun. This is a class of astronomical objects that has undergone gravitational collapse, leaving behind a spheroidal region of space from which nothing can escape, not even light. Observational evidence indicates that all, or nearly all, massive galaxies contain a super massive black hole, located at the galaxy’s center. In the case of the Milky Way, the super massive black hole corresponds to the location of Sagittarius A* at the Galactic Core. Accretion of interstellar gas onto super massive black holes is the process responsible for powering quasars and other types of active galactic nuclei.

First Image of Black Hole

On 10th April, 2019, The first ever real image of black hole was captured. It was so tiny in the picture that the crew scientists had to zoom it till it was formed bigger. The Diameter of super massive Black Hole in was 0.000100 cm.

The first ever picture of black hole has now open a new era for astrophysicists.

But the exciting thing is that, The General Theory of Relativity, first proposed by renowned Physicist Albert Einstein, had passed the test again. The thing is that, before 100 years before, in 1915 AD, among billion brain, only 1 brain of Albert Einstein could imagine it. Therefore, the very old General Theory of Relativity passed the test of several scientists and is in practice today as well.

“Imagination is important than Knowledge. Knowledge is Limited. Imagination encircles the World. Imagination is the language of Soul.”

Australia Doesn’t Exist And People Who Live There Are Actors Paid By NASA – Flat Earthers Claim

There’s a growing number of people who seem to think the world is, in fact, flat. But it gets better. They also insist that Australia is actually just one big hoax. According to a viral Facebook rant, the entire country (and presumably the 24 million people that live there) is completely FAKE.

The idea resurfaced at a some recent gathering of the so-called Flat Earthers in the Birmingham recently where over 200 people came together to confirm to each other that the Earth is nothing more than a giant pancake.

The origin of the “fake Australia” post started on Reddit back in 2017 and was written by a Shelley Floryd. But it appears to be back in the minds of the spherically-challenged at the moment.

“Australia is not real,” the rant begins. “It’s a hoax, made for us to believe that Britain moved over their criminals to someplace. In reality, all these criminals were loaded off the ships into the waters, drowning before they could see land ever again. It’s a coverup [sic] for one of the greatest mass murders in history.”

Moreover, the post reckons that all Australians are nothing more than computer generated personas and if you’ve ever been Down Under yourself: “you’re terribly wrong”.

Hilariously, the pilots are apparently all in on it – and have just been flying you to parts of South America all these years. Flat Earth theories have been shot down by just about everyone capable of rational thought, but the theory is still enjoying a current resurgence. Over 200 conspiracy theorists gathered at a hotel in Birmingham for the UK’s first Flat Earth Convention. The convention, which took place over three days, saw nine speakers take to the stage to explain their theory as to why the Earth is flat.

According to The Telegraph , Dave Marsh, an NHS worker who spoke at the conference, said: “My research destroys big bang cosmology.

“It supports the idea that gravity doesn’t exist and the only true force in nature is electromagnetism.”

While NASA has proved that the Earth is round using GPS, satellites, and images from space, Flat Earth believers claim that they have evidence that the space agency is lying. So what do you think about this? Let us know in the comments

Black hole, one of the most dangerous cosmos masses in the space. But what if our moon change into the black hole,what will be it’s effect on the earth.

A black hole the mass of the Moon would have an event horizon about the size of a sand grain. Specially, according to one of my favorite charts, a black hole moon would be a grain of fine to medium-fine sand, and could pass through a sieve. Since the Moon’s mass and position wouldn’t change, the tides on Earth wouldn’t change, either.

When you’re floating outside a spherical mass, its pull on you is the same regardless of whether the mass is concentrated at the center of the sphere or spread out throughout it. If the Sun were replaced by a black hole of the same mass, the Earth’s orbit wouldn’t change, although life on Earth might. With the Moon gathered into a point, there’d be no moonlight, which would affect the life cycles of all kinds of nocturnal animals. But compared to a lot of the other things we’ve done, that would be fairly minor.

The Earth’s orbit is stabilized by the Moon, but the lunar-mass black hole would probably serve the same role. This black hole Moon would be pretty low-profile. If it were much smaller, it would evaporate through Hawking radiation, but a black hole the size of the Moon actually absorbs more energy from the cosmic background radiation than it emits through the Hawking mechanism. Our black hole would really be black.

At least, if it didn’t eat anything. If the black hole devoured any objects, it would let off a tremendous blast of radiation. Black holes burn brightly as they devour things; the whirlpool of matter heats up as it falls inward, causing it to glow brightly. Fortunately, there’s not a lot out for it to eat, so it wouldn’t glow very brightly for now. It would spend most of its time drastically altering the orbits of nearby dust particles—one sand grain pushing other sand grains around. But there would be one interesting effect: In addition to getting darker, Earth would get colder, because moonlight warms the Earth.

It’s a very tiny contributor to our global energy balance; the Moon is five or six orders of magnitude dimmer than the Sun. But it’s there. Measurements show that global temperature varies with a 28-day cycle; all else being equal, the Earth is hottest during the full moon. It’s a tiny difference-small fractions of a degree-but it’s there. But it turns out most of this effect is not due to moonligh.The largest contributor is the fact that the Earth is slightly closer to the Sun during a full Moon.

Calculating the amount of energy radiated back to Earth by the Moon is deceptively tricky. The Moon reflects sunlight, but with some surprising twists. When the Moon is half-illuminated, you might think it would be half as bright as when full—but it’s much less bright than that. And once you account for that, there are even trickier effects to deal with, because science is the worst.
Then, on top of all the weird visible-light effects, the Moon also heats up under the Sun, then radiates that heat as infrared light.

There’s a great discussion of the Moon’s effect on the Earth’s energy budget in this article. The upshot is that the Moon’s infrared heat radiation turns out to affect Earth’s temperature about 10 times more than the visible moonlight, but still about 10 times less than the effect from gravity moving Earth closer and farther from the Sun. This also have affect on Earth’s radiation balance-the presence of infrared moonlight warms the planet by 1.2 milli-degrees Fahrenheit (m°F). Without moonlight, the planet would cool down slightly. But given the accelerating rate at which we’re adding CO2 to the atmosphere—which changes the Earth’s energy balance-we’d make up the difference in a couple of weeks. So all in all, the conversion of the Moon to a black hole might not even be that big of a deal.

“Concept of God as the Alien”

: The Green face,large eyes & abnormal head shape human like specie’s image came into our mind when someone spell the word ‘Alien’ in front of us. Is it really verified that all the alien must have that types of physical structure as we think & imagine about them ? No,it’s only our imagination about the shape or structure of alien.

Simply alien means living that used to live alive outside the earth. May be there are microscopic,unicellular organism survive & live in the water of titran(satellite of saturn), frozen ice of mars & saturn which are located at it’s pole region, Aren’t they alien ? Yeah although they haven’t the actual & same physical structure as we think about the alien, still they are categorised into the categories on the alien group because they are the form of life present on the out of the earth.

All the things that we have discussed above are just to understand the actual defination of the alien.

There are hundreds of hypothetical terms discussed about how human came  into the existence. All the 4,200 religions that are still into the existence on earth believe that all the creatures are created by god. Then science have try to define the god in some weird ways, that may be those superior powerful things that we are calling god are the alien in actual.

When we read historical books about religion,we can read that god came into the earth by some super speeds vehicle,they are bright & have different powerful weapon. If we analyze all the things,that super speed vehicle may be the UFO ( Un-identified Flying Object ) & the powerful weapon used by the god were highly developed strong technological weapons.

 And if we deeply analyzed about that god create us, then may be we are the off-springs of alien which were kept onto the earth by alien about thousands of years ago.

According to fuel dynamics,to burn the substances at least 16% of oxygen is needed to ignited. At the sea level the quantity of oxygen is 21% in atmosphere & when we goes rise to the altitude the ratio of oxygen is air goes decreased from 21%.As we have told that at-least 16% of oxygen is needed & for your information at the height of 4500 meter the ratio of oxygen goes down to the 16% so up to 4500 meter we can’t burn the fuel or fire.

As all of we know mount everest in the highest mountain or peek of the world, this mountain is from Nepal. The height of highest peek mount everest is 8,848 meter (approximately 9 kilometer), at the altitude of 8,848 meter the ratio of oxygen goes down to 6.6% & at this quantity of oxygen we can’t burn up the fuel or fire. Usually rocket fly up to 500 km & at this altitude the ratio of oxygen is zero, & at this condition we can’t burn up anything in normal condition. That’s why Limitedscience.com is here to solve out this question.

Since there is no air and space, rockets need to take oxygen with them into space. Inside the rocket’s engine, fuel and oxidizers are ignited in the combustion chamber, creating hot, expanding gases. That gas has pressure, and it pushes harder against the top of the rocket than the bottom, making it go up or forward. Since the fuel is burning, exhaust is released out the bottom.

Chinese scientists are planning to put an artificial moon into the sky by 2020 as a way to illuminate city streets after dark.Scientists hope they can hang the artificial moon above Chengdu, the capital city in the Sichuan province (Source: China Daily Reports).a

The moon, which would actually just be a glowing satellite, will reflect sunlight back to Earth. Scientists hope the light will replace streetlights. In fact, scientists think it will be eight times more luminous than the real moon. Wu Chunfeng, chief of the Tian Fu New Area Science Society, told China Daily it won’t appear too much brighter than the normal moon. Its expected brightness, in the eyes of humans, is around one-fifth of normal streetlights.

China is not alone. Russia tried launching an orbital mirror back in the 1990s. However, they dropped the project after the mirror didn’t unfold and it incinerated on its way into space (Time magazine reports).

Similarly, Rocket Lab out of the United States launched an artificial star. However, the star reportedly added to artificial light pollution and cluttering of Earth’s orbit (The New York Times reports).

Solar System

The Solar System is the gravitational bound system of the planets and the Sun plus other objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest eight are the planets, with the remainder being smaller objects, such as dwarf planets and small Solar System bodies.

Our solar system consists of an average star we call the Sun, the 8 Planets, the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium.

Planets

Planets are divided into 2 types; 1. Inner Planets, 2. Superior Planets. They are:

Inner Planets

  1. Mercury
  2. Venus
  3. Earth
  4. Mars

Superior Planets

  1. Jupiter
  2. Saturn
  3. Uranus
  4. Neptune

What are Aliens?

Aliens are those unspecified creatures that is believed to exist in outer-space. But in Human Words, Aliens means a foreigners or especially one who is not a naturalized citizen of the country where he or she is living. But here were are talking about the real Aliens from Outer-space. It is said that they are often seen in our Earth, and they are believed to travel through UFOs(Unspecified Flying Object).

So Do Aliens Exist? (Proofs for their Existence or  Not)

NASA’s Report ( Proof they Exist ):

It was reported by NASA that, “We backup from moon because we found some non-understandable creature on Moon. That is believed Aliens to Exist.” This was the time when they were landing Apollo 16. Apollo 16 was the 10th mission on Moon which was also failed because of Aliens on Marked dated April 16, 1972.

Proof they do not Exist :

An Atheist Giorgio A. Tsoukalo:

Giorgio A. Tsoukalo is a known Archaeologist. He believed “There is no Magic, no God, no Ghosts and no Aliens.” He gave the brief information about Aliens and concluded, “If Aliens were supposed to be living in this universe then we saw they are advanced than us. Some said they already invented UFOs but we cannot understand, How UFOs fly in sky and outer Space. And if they had seen us, they might already have finished up humans and flourished their civilization.” He told that All the stories related to Aliens were fake and those were just their Day Dream about Unspecified Creatures.

How do Aliens look like?

As none in this planet have seen Aliens, It is not confirmed yet how it looks. But its is believed to be small sized with a Oval or Triangle Shaped Head with no Ears at all, in White-Grey color as a Living soul in Universe.

Can it harm us?

It is often told Aliens can harm us, but in Nature it cannot. It is like a Soul which gets their energy via Sunlight. Most of the Aliens are friendly in Nature. Aliens cannot eat humans, instead it is said even they are advanced than us but they are scared of us and they will not harm us until we do to them.

These are all the thoughts of different persons from World, but it is not yet confirmed it exists or not. Scientists are still in the progress for finding the Clues for them. If they are really in friendly nature and do not harm peoples then it will be a really progressive thing for humans. But future is still to Come in next day to outcome the truth.
