What is outside the observable universe?

Answer 1

Scientifically precise answer: We don't know

Speculative answer: More Universe

As time passes, we can see farther and farther, and it seems that more of the Universe becomes visible, leading to the hypothesis that there is more and more Universe to see, but we have no way of knowing what exactly is beyond our sight. The "observable" Universe is exactly that—all that we can see and measure. Outside of that, we have no idea.

It's worth noting that science has no issues answering "we don't know" because that's the place where fascinating new discoveries are made on a regular basis.
