Space physics divides space into different dimensions. One dimensional space is a straight line that can be infinitely extended, with only length. Two dimensional space is a plane, with only length and width. Three dimensional space is a three-dimensional three-dimensional space, with length, width and height, that is, the real world. At this time, people naturally associate with four-dimensional space, so does four-dimensional space really exist?

At this time, people naturally associate with four-dimensional space You just really confused me because everyone I know only relates to three dimensions.

Three dimensional space plus time is four-dimensional space!

@moshishibie Time is not a 4th dimension.

@myklj999 Physicists have also debated this issue.

I think no. There's no four dimension space.

The four-dimensional world is still proving. Physicists are also exploring.
