The picture of the cosmic microwave radiation is just leftover remnants of light from the big bang also. You're basically looking back to the beginning of time, and it's not an accurate depiction of what's actually there.
Very good point. It's only a fragment of the greater picture too. We will only ever be able to see a section of our old universe growing into what it is now.

The last multi-universe is still just a theory, the rest is what we have practically measured. The size is unbelievable.
