well, it's hard to tell...they seem to have found an 'edge' but there's only static passed that...I like to think the universe is as infinite as the Word of God that created it...it was made by His Word, which is a material, if you will, that's as infinite as God the Word, Himself....but I'm one of them silly deluded believers, so what do I know....our minds are infinite, at least that's how I see them. God packed a whole universe inside our little mind...my mind has no boundaries, there is no end, it goes on forever...
so, where ever I/you go, or where ever we are, we carry our infinite universe with us, and they don't collide with anyone else's...we add stuff to ours and each others and but they are never filled...
i found this video, I believe this fella has some good points, what is really mind blowing, is our solar system is at the center of the view-able universe (@4:40) which evolutionist call 'the axis of evil' lol...anyway, I reckon I didn't help much, but there's my 2 cents.
