This question often continues to show that what is life outside the Earth?

If there is life outside the Earth then is there the presence of a wise life like a human in that life?

The rumors / the so-called news of the UFO / indigenous people all over the world are coming out. Even Hollywood / Aliens are a major storyline in Hollywood films, they are mostly presented in the movies as villains whose purpose is to consume the natural resources of the earth (water/ gold/mineral) or to humankind their slaves Use as a caste.

Is the existence of alien / alien organisms?
According to the current science, there is no reason to not have the life outside the earth. There is no such feature in the Earth or Solar System that there is the only possibility of life on earth.

Scientists believe that in outer space there are material and conditions for the origin and development of life. There are about 200 billion stars in our galaxy, in which our sun is a normal star. The galaxy's width is one million light years and thickness is about 20 thousand light years. Our sun is not even in the center part of the galaxy. It is about 30 thousand light years away from the center and continues to revolve in the galaxy. In the universe, there are billions of galaxies such as and apart from this. The second big galaxy beyond our galaxy, Devyani is about 20 lakh light years away from us. Extremely remote galaxies of the universe are about 10 billion light-years away from us.

So in this vast universe, what is inanimate everywhere except the earth? Elements from which the things of earth have been created are found more or less throughout the universe. While the laws of physics apply to earth objects, the rules also apply to the matter of very remote objects. Therefore, it can not be said that only the origin and development of life is possible on earth. The existence of even more advanced civilizations of life is possible on other objects of the universe.

In calculating the advanced civilizations in the galaxy, the University of California, USA astronomer Frank Drake has presented an equation, which is called the Drake equation. Calculating the average rate of birth of stars in the galaxy, the planetary system of stars, the number of planets, the number of planets that can hold life, the number of planets that can give birth to advanced technology, the life of advanced meetings, etc. With the help of Drake equation, the prevalence of life in the galaxy is detected. Scientists have discovered that there are millions of stars like our Sun in 200 billion stars of the galaxy so that we can not regard our stars as unique. Famous astronomer and popular science presenter Karl Sagan discussed this equation so many times that it has been called the equation of Carl Sagan.

Based on the facts received by Frank Drake in 1961, it was estimated that in our galaxy only life is possible in about 10,000 planets. After 40 years of that equation, in 2001, after the improvement of the method of drake, the further equation was made, it was said that life is impossible for thousands of millions of planets.

That is life on earth, so there is life also elsewhere. The answer to our first question is that the existence of Alien is possible.

Does the alien/alien come to earth?
Can they invade Earth as shown in movies?

Maybe not The distance between the stars is extremely high. Proxima Centauri, the nearest star of the Sun, is 4 light years away; it takes light 4 years to reach us. The speed of light is very high, it travels around three lakh km in a second. It takes only eight minutes to reach the sun from the sun to the earth for comparison. In order to travel for such a distance of many light years, our fastest rocket of the present will take hundreds of years to travel so far.

There is a lot of hassle in such a long journey, in which such a long journey of many years will not be easy for humans or any other intelligent creature. There will be a lot of experimental problems in the construction of the vehicle that will be used for the journey, such as the ration, water, clothes, energy arrangements for this long journey in this vehicle. It will not be possible to take food items for many years in the vehicle, in such a situation, arrangement for the cultivation of trees, plants, and plants will be required in the vessel. To build the energy of the operation of large vessels and the use of passengers, the power plant will be built. The air should filter the carbon dioxide like toxic gas from the air in the production of oxygen. For the reuse of used water, plants need to be used for the reuse of waste generated. When all these plants are planted, they will be shaped like a small city. It is not easy to create such a large planet on Earth or on the planet, and it will not be easy to build the spacecraft of this size.

Sharp craft by light speed
The biggest problem with the speed of light travel is that according to scientific rules, light speed or faster journey is not possible. This is a violation of Einstein's theory of relativity, according to which the light speed is the maximum limit of any particle. Any object that holds its mass cannot achieve light speed; It requires infinite energy to achieve the speed of light which is not possible.

Let's assume that somehow this breakthrough of relativism was taken out and the vehicle carrying the light speed was also taken. There will be a problem with time dilation in this stage. We know that the speed of time is not uniform everywhere. The speed of time in the light-powered vehicle will slow down, while the speed of time on the Earth / Alien Planet will remain normal. It will take 4 years to reach the Proxima Centaur from the Earth with light speed, but the Earth will pass centuries.

All these experimental reasons do not seem to be possible for Elion to come to Earth.
