No, there is not there is no edge to the universe, and there is nothing outside of the universe. there just IS the universe.
The name Universe refers to all that there is in existence, therefore nothing can be outside it.

We don't know what it's like outside the universe because the big bang caused the expansion of mass, so were pretty sure nothing happens outside the universe.
An alternative universe is a hypothetical world outside of our own, depicting a different way in which the universe could function.
No. We can observe some of the effects, such as the CMBR (cosmic microwave background radiation) and the expansion of the visible universe, but seeing it directly would require being outside the universe itself - which is impossible for us.
What is outside the universe.
