Universe and Life

A great scientist of our times Sir Stephan Hawkings and Russian millionaire Yuri Milner has launched a $100 million project for search of alien species. Now consider this fact that universe in unbelievably vast and there are millions of earth like planets with conditions favourable for existence and evolution of life. 




Now the question is why should living beings be like us, they can be different from us. Intelligent life might have evolved in a different way somewhere else in the universe. Maybe they are gigantic or maybe they are microscopic. Their might be existence of alien life that may not require oxygen at all for their existence. 


Here on earth we can't live at temperatures that are beyond  60 degree Celsius. However there might be existence of living beings somewhere in the universe that maybe tolerant to very high temperatures.


Earth beings can't survive in vacuum because of the internal pressure of the fluids exerted on the cell walls. The cells would burst as soon as they are in vacuum. There maybe existence of intelligent beings that may not be planet based but are free floating space entities. 

In every galaxy there is a massive black hole at the centre around which other bodies or systems rotate, like the sun is rotating around the black hole that is at the centre of the Milky Way. There are galaxies that have a more massive black hole, the velocities of the other planets and stars have to be high enough to prevent them from falling into the black hole. 

Life that might have come into existence on the planets in this galaxies maybe different from us. Living beings evolve generation after generation depending on conditions of the place where they exist. 

"Facts can be stranger than fiction", there might be a massive lot about life in the universe that's waiting to be explored. Just because a planet does not have earth like conditions is no reason why it should not have life,after all what are living beings? A set of entities that survives, reproduces, adapts, evolves becoming higher organisms. 

It is of course a mystery, why life should exist on earth or anywhere else in the universe at all? 

There is so much that remains to be explored about the universe, it would take many Milena to explore it. Its bound to be an exciting journey of discoveries. In every step we will find something new. Maybe someday in this process of discovery we will find God.
