The Universe

The universe is extremely vast; incomprehensibly huge. None the less, some day it will cease to exist as we currently perceive it. The sun wil burn up completely in about 5 billion years or so. At that time the solar system will no longer be habitable. Will humans be around at that time? No one knows.

The theory that currently has the most support in explaining what we think will end the universe is one called "The Big Freeze". The big freeze theory claims that the universe will continue to expand until it reaches nearly absolute zero and all things cease to move. This is supposed to happen in about 10100 years. For comparison the universe is currently 13.7 Billion years old (13,700,000,000) where as the big freeze would happen in approximately 10100 (100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000, 000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000) years, and the entire history of the human race is a mere 200,000 years.
