Imagine life beyond earth, this is what modern science is ought to prove. There are innumerous instances when scientists scan for life beyond earth and many come up with their own theories. Research work by an Indian scientist published in the Springer Journal Astrophysics and Space Science gives alarming evidence for such theories. The study reveals the research work of the team led by Chandra Wickramasinghe, professor and director of the Buckingham Centre for Astrobiology at the University of Buckingham. As per the team there are a few hundred thousand billion free-floating life-bearing Earth-sized planets may exist in the space between stars in the Milky Way. The team went on to suggest that these life-bearing planets originated in the early universe within a few million years of the Big Bang, and that they make up most of the so-called "missing mass" of galaxies.
The scientists calculate that such a planetary body would cross the inner solar system every 25 million years on the average and during each transit, zodiacal dust, including a component of the solar system's living cells, becomes implanted at its surface. The free-floating planets would then have the added property of mixing the products of local biological evolution on a galaxy-wide scale, according to a statement of Buckingham University
Since 1995, when the first extrasolar planet was reported, interest in searching for planets has reached a feverish pitch. The 750 or so detections of exoplanets are all of planets orbiting stars, and very few, if any, have been deemed potential candidates for life. The possibility of a much larger number of planets was first suggested in earlier studies where the effects of gravitational lensing of distant quasars by intervening planet-sized bodies were measured.
Are we the lone sentient life in the universe? So far, we have no evidence to the contrary, and yet the odds that not one single other planet has evolved intelligent life would appear, from a statistical standpoint, to be quite small. There are an estimated 250 billion (2.5 x 10¹¹ ) stars in the Milky Way alone, and over 70 sextillion (7 x 10²² ) in the visible universe, and many of them are surrounded by multiple planets. The odds of there being only one single planet that evolved life among all that unfathomable vastness seems so incredible that it is all but completely irrational to believe. But then "where are they?" asked noted physicist Enrico Fermi while having lunch with his colleagues in 1950.
Whatever be the argument it looks like we are not alone in this massive system. May be some day the clearer facts with sound proofs come up for us to understand. True sometimes truth is stranger than fiction. (With Inputs from Internet- Aarkay)
