Are space and time really 2 separate things? Why can we describe the first 3 dimensions in terms of space, but then we switch to time when we move to the 4th?

There is no difference between a spatial dimension and a temporal one. In reality, there can be infinite spatial and infinite temporal dimensions. It just so happens that we live in a universe with 3 spatial dimensions and one temporal dimension. Doesn’t it male sense to engage with that physical reality?
