Explanation:

Generally speaking, when we talk about a fourth dimension, it's considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.

Answer 2

Explanation:

There is no such thing as a fourth dimension of an object. No one can imagine a fourth direction perpendicular to length, width, and height.
