What number is highest than the highest real number?
Right. But what's north of the north pole? What's on the other side of a Mobius strip? What's outside the universe? They're all similar questions.
The term "outside the universe" refers to a place you cannot get to, cannot be measured and cannot affect the rest of the universe. It has the reality of the place north of the north pole.
The Universe is infinite beyond the boundary of the visible universe.. but let's clear up this infinity. It breaks down like water clashing against rocks. So it is infinite in scale, and breaking down to a higher number in quantity. 1 rock makes lots of sand. 1 infinite universe is a conversion from scale to quantity.
The visible universe has a boundary, it's due to the finite age of the universe, the speed of light and space-time expansion. Whether beyond that visible horizon the universe has an 'edge' is unknown and perhaps unknowable.
If the universe is finite then it can be unknown not unknowable.
No. Learn some cosmology.You probably write about the sphere/boundary which separates the volume filled with the Einstein spacetime and the dark energy from the pure Einstein spacetime or truly empty volume.
