And when the sky will split it will become rose like red hide. (Holly Quran, Chapter: Al-Rahman, Verse: 37)

Evidence that the Universe began with the Big Bang is quite compelling. 13. 8 billion years ago, the entire World was compressed right into a microscopic singularity of which grew exponentially in to the vast cosmos all of us see today. But what does the longer term hold? How will the Universe stop?

Astronomers are pondering the best fate with the Universe for 1000s of years. Within the last century, cosmologists thought to be three outcomes to the end regarding everything, and it also all depended about the critical density with the Universe. In the event that this crucial density had been high, then there was clearly enough communal gravity to be able to slow and at last halt the expansion. Billions regarding years sometime soon, it would certainly then fall in upon itself yet again, perhaps making another Huge Bang. This is known as a closed Galaxy, and the last result could be the Big Crisis. Should the critical thickness was reduced, then at this time there wouldn’t be adequate gravity to hold on to things with each other. Expansion would keep on forever as well as ever. Personalities would expire, galaxies will be spread separate, and every thing would cool-down to the background temperature on the Universe. This really is an available Universe, and the finish is known as the Big Freeze.
