I mean, does it have an outer "wall"? If so, what defines that wall?

The definition of "universe" is EVERYTHING. so there's nothing outside of it. But if there was, it would be singing purple dinos wearing polka bow ties.

Well, since the universe encompasses all that we can perceive, then outside the universe would be something we cannot perceive. I'm thinking inter-dimensional possibilities.
Apparently, string theory already suggests extra dimensions could exist, so I think that's what you're looking for.
What would it be like? I don't know, and I don't think I could even imagine what it could contain.
Let me know if you find it.
As for the boundary between this universe and another being a 'wall', I think it would more likely be something on the order of an energy portal of some sort, perhaps an energy field inside the smallest part of an atom, or maybe the center of a black hole, something as yet undiscovered.
Have you ever heard of the Mobius strip? A simple concept that allows you to travel forever in a straight line and never reach an end, yet it is done in a finite space. I think looking for the 'end of the universe' in the conventional sense of traveling until you get there would be futile, much the same way as traversing the Mobius strip.
It would be fun to find out for sure.

This universe contains everything that can be sensed by both physical and scientific sensors. These include sight, taste, hearing, touch, smell, microscopy, and telescopy (X-Ray, Visible, UV, Radio) and all the many scientific instruments that have been invented - ever.
It does not contain those things that exist outside the physical - sensory reality: Time, if it actually exists a a separate 'thing', God, Ghosts, Prophetic visions, Spiritual encounters, and perhaps other things such as these that can not be measured scientifically, or repeatably. (Maybe we sill find a way to measure them later) These things exist in another reality that a scientist might tend to not believe in. "If it can not be proven to exist, then it doesn't exist." is a mistaken point of view. to be scientifically correct, it should be "If something can be proven to exist, this it exists. If it can be proven to not exist, then it doesn't exist. If it can not be proven either way, then we can not know whether it exists or not."
The universe contains everything that can be "seen" by any and all sensors that we can build. But just because we can not see beyond a certain distance, we still can not prove that 'nothing' exists beyond that distance. We would have to go there and reach a black wall - or whatever color - or suddenly, after traveling for a billion billion light years in our faster than light cruiser, suddenly find ourselves approaching Earth once again, could we say that we had proved that the universe was limited.
;-D I believe that the proper use of science is to prove or disprove what exists in this physical universe, so that we can discover more of the laws that make it work. If a scientist can not prove or disprove, then he has no business saying something exists or doesn't exist. Fake scientific statements should be a punishable crime. Take for example the statements saying that the Apollo Moon shots were fake. This causes gullible people to doubt reality. This is not good for society. They should be punished for 'dis-educationalist activities!" ha ha ha ha!

The concept that everything has a beginning and an end is purely a human one, because everything we experience does.
The universe has likely more complex dimensions than we can imagine and cannot be explained in simple three dimensional terms. It simply has no beginning and no end as we would normally perceive it.

Absolutely anything, outside the universe literally means outside of the physical laws of this universe.
The true nature of genius (and insanity) is the ability to contemplate the incomprehensible.

That's a very good question.
But I'm afraid that no scientist, priest, or astronomer will ever be able to answer it.
The concepts of space and time are too complicated for the human mind!

When you define the universe as everything, there is no outside.
Compare it with this: Suppose n is the greatest number, then n^n is much greater. So there is no greatest number.
