Space-time and beyond

If we want to understand the universe, we must first understand "space-time".

Our classical reality consists of three dimensions of space and of time. In other words, we are in a four-dimensional perception of reality.

Most of the time, when it comes to space, it is understood that the natural events occur and the outdoor space we focus on: Flat, solid, always the same, in a sense, the background where all natural phenomena occur, a decor that we have to be on.
