Is the universe spherical?

Universe cannot be defined by only 3 dimensions.

Thats like saying you can't define any event with photos. The universe is now, everywhere. Take an image of everywhere, right now, and you have defined the universe in 3-d.
Hi all. I don't know a lot about this topic, but I have been following this thread in hopes of learning. So please excuse me if this post seems to lack a lot of the intellectual depth that seems to be required in this field.

I am just wondering, are there any scientific developments on theories concerning what is beyond the universe? Or does the universe sort of fold back in upon itself? If the universe is spherical, would this make sense?
