Extraterrestrial Life:Chapter 1

British Scientist Sir 'Stephen Hawking' is worried that any extraterrestrial life we find is likely to be a creature out of the movie 'Predator'.

What is Extraterrestrial life?

Extra means 'beyond' and terrestrial means 'belongs to the earth'.So altogether,it means 'Life beyond the Earth".

Many Scientists disagree with this theory but many others won't stop looking for them beyond the Earth.Scientists are trying to find out, if the stars have earth-like planets which has life on it.In a Discovery channel documentary, Dr. Hawking suggested that with 100 billion galaxies in the universe,it seems perfectly rational that aliens exist.While they are most probably microorganisms or basic animals,he suggests the threat posed by intelligent life forms,if they exist, could make reaching out of them to be a little risky.I would personally quote that "Ignoring the threat and waiting for them to find us,is not a good idea."

Martha Haynes-Astronomer at Cornell University,New York quotes "Technology will continue to progress and we will surely see major breakthroughs in the next 5 years"Today, we are in a position to learn a lot more about what else might be out therein the cosmos and in particular we are on the verge of finding planets planets which might support the existence of life forms says Dr. Haynes who adds that a new planet is discovered everyday.

Techniques for detecting Earth-like planetsare enhancing everyday.I suppose an exclusive new range of smarter telescopes will  be able to rule over almost 100s of planets.Though,we need to agree with Sir Hawking that the majority of alien life won't be intelligent like us,most argue potential benifits of not reaching out far, outweighs the risks of doing nothing.

However, David E Pitchard, a Physics professor at Massachusetts Institute of technology says that "Aliens that we contact are likely to be far in advance of us and may well have the capability to find out a great about us.Even if we don't formally contact with them".So, I think talking would be okay.Moreover,it could be very interesting.

In some state of mind,I feel that this is not a big deal.Suppose an alien would come down to Earth,shook your hand,and take your sister for a date.Will you still doubt their existence.I don't understand that why people are not ready to deal with the existence of Aliens.We'd rather talk about Kim Kardashian,Peter North or Shahrukh Khan .That's why i think the aliens haven't come out of their spaceships and poked us.

We are still babies, and yet we have to learn how to walk with them.
