Thanks for replying!

Thanks for the reply. I was asking this question so I could get a better idea about our universe, as a total layman. I am not good at math but I was thinking something like this, sort of similar to what you posted, that way back when people thought the world was flat it was because they...

Thanks for the information!

Do any scientists believe that the universe is far bigger than the observable one?
