Physics major at IIT-J researching in theoretical particle physics.

We have 3 "physical" dimensions. The 4th dimension we consider in relativity is time, which constitutes the understanding of the spacetime continuum. There is also a branch of cosmology that believe gravity to be the 5th dimension.
