Serious How Big Is Universe?

Its infitely big because its making more planets in the unvirse every minute/nano second

I think that the universe is in the form of a sphere just like our planet and there are many other universes next to ours for all this the mathematicians came up with a Graham's number

its as big as my left ball sack hope you like that..

i believe that the universe is a sphere, however the sphere in an infinite amount of light years long.

I think the universe must have an end, but where is it? What is beyond the end? Can humans really reach the end of the universe?

They said: the universe is 13 billion lightyear big, because we dont see nothing after that.
Excuse me, but just I think, here is something wrong whit that?
This is truth in only one case: when we are in middle of the universe...

It's big considering the fact we searched a long of it and there still of unknown variables that we have yet to discover up there

Sometimes the best thing to do is to say "I don't know". There are things we (as the mankind) don't know yet and it's pointless to makes assumptions. Otherwise bad things happen, like religions.

It is always expanding too. HOw crazy is that huh
So nobody really knows
