Space is said to be infinite. So , if you hop on a space ship and you keep going straight ahead , you'll never reach an end.

i'm not a science freak.. but how can it be possible ? I mean , even if it stops , where does it stops ? and what behind that "border" ??

Are there any theory's ?? or its just a silly question..?:confused:

You are encouraged to read any popular science book on cosmology... Brief History of time is not a bad start...

If you go straight in a spaceship you will come back to same spot where you started from.... hard to imagine?... yeah but thats true because space is convoluted... what we think of staight line in 3D is some other curve in REAL space(which is 4D including time)... Imagine a plane going straight in sky and its shadow is falling on hill surface(2D)... if you just see shadow it will follow weird cruve depending on topography of hills... distortion comes from trasition from 3D to 2D... Its just a crude analogy of space travel some similar transition happen from 4D to 3D...
In nutshell, universe is finite but you can never get out of it... there are no boundaries between universe and non-universe... what we call boundary is direct signature of big bang... outermost part of universe was first-most of fly away in big bang... since there was no "time" and "space" before big bang (read the signature)... there is no time and space beyond boundaries of universe either... the question itself is invalid...

If you start straight you will reach the point you started from but from oppsote direction after having nice tour of whole universe, the way if you travel around the earth... I am not saying this, General Relativity says so:-))...
