3D - 2

If our universe was a 4d sphere then would it be possible for us to go beyond our universe?

For example, our universe is a 4d sphere, and we traveled at infinity speed, (if it was possible) would we just keep going around it circles? If that is the case then what would we have to do to go beyond our universe?

1. There's no such thing as "beyond our universe." The shape of our universe is probably something that wraps around itself so there is no "outside." It's pretty mind-boggling.
2. Actually there might be a possibility of going into hyperspace, when traveling extremely fast, and going into a parallel universe, or another universe in our multiverse... See there is a theory that our universe is part of a multiverse, a sea of universes... Read up into quantum mechanics, and youll see what im talking about..
3. No. Our universe is not finite, neither is a tetraspace (4d universe). Using (unreal) numbers, lets say our universe equals infinity times three (for three dimensions). Lets say the tetraspace our universe resides within is called infinity times four. Note that both equal infinity still. Looking another way, picture an infinitely stretching plane within our universe. That plane is 2d, yet we, 3d people could never go "beyond it". We could travel at infinite speed for our whole lives (a concept which doesn't really exist, because infinite speed is equal to teleportation, and thus a paradox would be created) and would still never reach the end of the plane, simply because there is no end.
