the existence of a fifth dimension?

[spacing_out_in_space]

the first time i ever got interested in aerospace was when i learned that space has four dimensions. after recently re-watching interstellar, i was wondering if a fifth dimension actually exists...time itself being a dimension in space is astonishing and the fact that time swaps space when an object falls into the black hole makes me wonder what going through time as just another dimension would be like in a 5-D world. do you believe in the existence of a fifth dimension?
