Communication With Aliens Possible...??

                   Extraterrestrial life ...  

           We all know that how we Humans evolved on Earth over a period of approximately six million years. It means that we took more than 6 million years to become what we are today. Now we are going to discuss about Extraterrestrial life.

           

          So,...what Extraterrestrial life is....?? Quiet interesting question, isn't it...??

 

As many stars as there are in our galaxy (100 – 400 billion), there are hardly an equal number of galaxies in the observable universe—so for every star in the colossal Milky Way, there’s a whole galaxy out there. All together, that comes out to the typically quoted range of between 1022 and 1024 total stars, which means that for every grain of sand on every beach on Earth, there are 10,000 stars out there.

The science world isn’t in total agreement about what percentage of those stars are “sun-like” (similar in size, temperature, and luminosity)—opinions typically range from 5% to 20%. Going with the most conservative side of that (5%), and the lower end for the number of total stars (1022), gives us 500 quintillion, or 500 billion billion sun-like stars. 

There’s also a debate over what percentage of those sun-like stars might be orbited by an Earth-like planet (one with similar temperature conditions that could have liquid water and potentially support life similar to that on Earth). Some say it’s as high as 50%, but let’s go with the more conservative 22% that came out of a recent PNAS study. That suggests that there’s a potentially-habitable Earth-like planet orbiting at least 1% of the total stars in the universe—a total of 100 billion billion Earth-like planets.

Get out of that scientific language, just understand that presence of Extraterrestrial beings in universe is less scary than to be alone in this entire universe....

Everyone knows that we (Human) Beings get evolved. In fact, every living organism is either evolving or evolved. But this case is on the Earth, our home planet. As we got evolved on a planet Earth, besides Earth, there would be another being maybe like us or maybe more advanced than us. Overall, the life evolved on other planet than Earth is called Extraterrestrial life.

 

 Probably, a question popping up in your mind is, Does Extraterrestrial beings looks like this..

 My answer, is no. This is an imaginary assumption of extraterrestrial beings to make our imagination easy to capture them in our mind...

          Isn't an word Extraterrestrial being is a little hard to pronounce and unlistened for you...??  Let's make it easy,.. we can say that the word 'Alien' or Extraterrestrial being. That's very easy. 

          Scientists first began searching for alien signals shortly after the advent of radio technology around the turn of the 20th century, and teams of astronomers across the globe have been taking part in the formal Search for Extraterrestrial Intelligence (SETI) since the 1980s.

        So do the Aliens really exist?

 To be honest, no one can be assure about that thing not me, not you and well known scientists also...

        So, what is in our hand....Exactly to create theories on that thing...

 First of all let's talk about types of Civilizations...

Type 1: One can use and store all the energy available on its planet.(We are at 0.73 on this scale)

 

Type 2: One can harness the total energy of its planet's parent star by Dyson sphere. (Dyson's sphere means covering planet by huge sphere.

Type 3: One can control the energy of the entire Galaxy.

 

 Let's have a look at a extraordinary and famous theory.

 

 First theory we are going to discuss about is called Fermi Paradox..Yes it must be special because we are discussing about is at very first..

    

          This theory explains that our universe is very much old that the scientists trying to find out the exact age of universe from decades and still searching...but they can't figure out the exact age.

In the early 20th century, physicist Enrico Fermi asked himself a nows famous question: 'Why haven’t we found intelligent extraterrestrial life yet or why haven’t they found us?' This is sometimes called the Fermi Paradox or the Great Silence.

You also have thought about this thing as the great physicists do and that's why you are here , reading this...

So, there are many reasons of Why we cannot see Aliens ever?  According to Fermi Paradox.

    

         First reason is that our technology is at very early stage compare to the Universe. If there are Aliens many many light years distant from us then e cannot see them properly. Our Telescopes helps us to find planets only. They cannot see that closer or high defined.

  

          Second reason is that age of Universe is approximately 14 billion years and age of our Mother planet Earth is only 4.5 billion years. So this could also the possibility that the Aliens born much earlier than us and got distincted before our birth.

     

         Third reason is Dark energy. Who don't have any idea about dark energy they can assume that the type of energy extremely opposite than how we see it in our daily life. So due to dark energy our Universe is expanding and galaxies are going away from us by every second. If we do any kind of late to search the Extraterrestrial beings it will become harder day by day. Maybe many of the civilizations have already gone very far from us during our Evolution.

         

          Another reason is Zoo hypothesis.

     What is Zoo hypothesis..?

        If there are any kind Modern civilization which can see us. And they can realise that our technology is very primitive. And therefore they would think that there is nothing to get from us hence they do not disturb us and simply watch us  evolving. Just like we do in Zoo. We watch the jailed animals.

         Last reason is differ in technologies. This means that presented Alien's technology is way way different than ours. Hence we cannot receive their transmissions and they ours.

        

       This was a little bit about Aliens to make you aware about real science about them. 

Have a good day...
