how big are we?

Question

if you cut a atom a half then cut that half in half and continue as long as there is a half it will go on forever, now if you look at space when does it end, how can there be an ending it can not stop, so where do we stand ??

Answer 1

our universe goes on for an UNKNOWN distance. We can only see in a 46.5 billion light-years radius.

beyond that, beyond us and our universe, especially beyond the way humans thing of big,
we need to go back to the quantum mechanics you talked about.

we find there is actually something much bigger that CAN contain US in something that SMALL

its called the Multiverse of infinite levels of possibility.

A HUGE container holding
our dimensions (a brane) and an infinite amounts of other dimensions (other branes)

these branes actually float around and crash into each other.
each time the crash, they create brand new universes. then it repeats....... forever


from our point of view,
we/our universe is even LESS, than insignificant.
the mulitverse is insignificant.

a strange paradox now since we're stuck in the middle.
How big are we? I think we should really be asking is how infinitly small are we? are we a singularity?

Answer 2

No one knows. The known universe is about 6 billion light years wide.
That's 186000 miles per second,times 60 (minuets) times 24( hours) times 365 (days) times 6,000,000(the amount of years.

Answer 3

Get a life. Even better: get laid. And there will be no more cutting of poor, helpless atoms. Or mindless trolling on Yahoo.
