Possibilities of non-earth life

        I always wondered why do we need to look for the other planets which are habitable. The answer to this question is simple. To Survive!! Every living or non-living thing has its expiry. So, our lovely planet earth is going to die after some billion years. The reason for the death of earth is Sun. It is estimated that after around 4 billion years from now, the sun will become a red giant. It will swallow the earth.

        Other possibilities of the death of earth are endless. It may be an asteroid impact or climate change or alien invasion. Yeah!! It sounds crazy right?! I feel like, in the next 100 ye
ars, we will be able to detect the first non-earth life in the universe. But what will we get from this? A partner in this whole universe? Who knows how aliens will be! Will they be friendly? Or will they be like typical aliens shown in Hollywood movies?

 

        So the question comes, how should we find life? Scientists often speak about the habitable conditions for a sustainable life. But I feel that who the hell are we to decide that?! Now, just read carefully what I am going to write next!

          We are on the planet Earth which is one of the eight planets in the solar system. No other planet in our solar system has life. (Though, a mere possibility of life is still there on the moons of Jupiter and Saturn. Mostly Europa and Enceladus. We don’t know the interiors of these planets.)

Our solar system is one of the billions of solar systems in The Milky Way Galaxy. No one knows if there is life in the milky way. Now, our Milky Way galaxy is one of the 100 galaxies in Virgo Supercluster (Virgo SC). The observable universe contains approximately 500 Million superclusters in it. And the most fascinating thing is, ‘universe is only a drop of water in an ocean named Multiverse!’.

        Now just imagine, what is OUR definition of HABITABLE in front of all this??! Where are we in the Multiverse? And scientists state that if a planet has oxygen and water on it, the planet is habitable and can contain life. See, I understand that scientists are looking for a habitable place for human beings and also they are looking if there is someone else like us in the Universe( Yes! Not Multiverse. Because we still don’t have that much-advanced technology to explore different Universes!) But I personally feel that life can be anywhere! Who knows if there are creatures who breathe CO₂ or the creatures who cannot survive in the temperature which is suitable for us!

        The possibilities for a non-earth life are endless! We just need to improve our scope and the domain in which we are searching for!
