An earth like
planet has to be
formed if a cloud of gas of the size that formed the solar system condensed under the pull of gravity. Astronomers have proved this beginning with a cloud of dust and gas of the same mass and density that is thought to have served as the origin of the solar system and setting up experiments for random motion and collision gravitational forces. In every case a planetary system very much like ours resulted and an earth like planet formed more or less at the same distance as the earth is now from the sun. Some scientists believe that there must be many earth like planets in the universe as a concomitant of the formation a
sun like
star anywhere in the universe. It has been proved too that on an earth like planet placed in the vicinity of a sun like star
Life has to be evolved. After years of careful study of the primordial earth atmosphere, it is suggested that life originated in this planet through the chemical changes in the primordial conditions with the sun as the energy source. Even in scanty interstellar gas ( its is so rarified that they exist as atoms) researchers have observed that molecules that
Form always tend to progress towards amino acids and fatty acids –the basis of living tissues. Ever since living cells formed they were subjected to the laws of
evolution which proceed form simple to complex forms. In the course of million of years life has evolve from simple cells to the complexity we see in the humans. No power could have stopped this relentless march. Man had to be evolved. It si through the multiplication of the living cells that nature has managed to carry out this process. Each organism takes birth, reproduces and disappears. From the nature’s point of view this is of paramount importance. Similarities between various species have been observed since the time of Aristotle. But it was Charles Darwin who presented the comprehensive thesis. Whatever Darwin could not explain then has been taken up and cleared subsequently. Now THE EVOLUTION OF MAN FROM THE LOWER SPECIS IS MORE OR LESS UNIVERSALLY ACCEPTED. Today we know that in no other planet of the system there is life. But it could have sprouted out in the thousand of earth like planet placed in the ecosphere of their sun like stars. IN the young ones life may be just germinating, in the older ones more complex forms could be roaming about. I others evolution may have reached our levels of intelligence or more. But no form is permanent here. Everything formed will ‘unform’. The death of our planet and the sun that powers it now are certain events. The earth will remain in its present orbit, shape and surface until the su leaves its main sequence. Once the sun starts to expand signaling its demise, death of earth and all the life it supports will be imminent. Many suns are now probably forming up while many others are in their death throes. The formation of suns, planets an galaxies, their eventual death, the reorganization of the scattered cloud gases forming new stars and planets will go on with the unwinding of the universal clock. In this eternal cycles of the universe we got birth down here. Our lives are infinitesimal energy bubbles forming and bursting almost simultaneously. Within this framework we start our lives and build up hopes But we trapped for an illusive moment
