The current best theories depend on 'cosmic inflation'. This theory suggests that the universe in the first tiny fraction of a second doubled in size many many times. It grew so fast that most of the universe is so far away that light leaving it will never reach us. For that reason, science usually confines itself to the 'observable universe' which is that part of the universe which is close enough to see in principle, the rest is so far that it is beyond reach and cannot affect us while the speed of light is a finite limit. Some scientists (and me on some days) think that this 'inflation' never actually stopped. What happened was that a tiny bubble of the universe stopped inflating and just expanded at ordinary big bang type speeds. Outside our local sphere, the universe could still be inflating, and bubbles of conventional universes with their own big bangs appearing, carried away by inflation far faster than any normal universal phenomenon. "Space is big... really big ... I mean you may think it's a long way down the road to the chemist's ... but that's peanuts to space."

let me tell you a little story... once a man, in his dream...saw that, he's on a visit to the universe by God... one after one...they two were passing on...but there were no end of it...the man got so tired...and said,"O angel, please stop! I cannot afford it anymore.""Look at the back," the angel replied,"There's no trace where you started from...and look forward, there's even no trace of ending either..." that was happened a long ago...and the universe is ever expanding...now, guess how big the universe could be...it'd help you a bit..
