My question actually is: Consider ourselves. We live in a 4 dimensional space considering time also as a dimension. Let us assume that in reality our universe is finite and 5 dimensional. So, ofcourse, we wouldn't be able to perceive the fifth dimension directly. (Not speaking about any abnormalities in the physical laws which may point towards a higher dimensional universe and thereby help us to conclude that our universe is in fact 5 dimensional. ) So the universe that we will be perceiving will be just a finite projection of the 5 dimensional universe (for better visualization I used a sphere(3D)) or will the universe be perceived as something 4 dimensional and infinite?

Spherical Excess will help to calculate the size of the sphere, given that the being is aware of the fact that its universe is 3 dimensional. As far as perception is concerned a 2 dimensional being should not be able to directly perceive the third dimension unless there is some procedure for determining the same. Can you elaborate on how the being will determine the number of dimensions of its universe or how will the being determine the fact that it is on a sphere ?

Assuming that higher or lower dimensional beings exist, how would a 2-dimensional being living on a 3 dimensional sphere with a finite radius perceive the sphere. Will the being perceive the sphere as a finite radius circle that is a projection of the sphere or will the being perceive it as an infinitely large plane?
