Time: yes, it's a dimension, but no, it's not like space
Briefly

The intuitive concept of distance in our three-dimensional space is a straight line; however, the reality of four-dimensional spacetime reveals that distance varies significantly.
While three dimensions allow us to move through space in a straight line, the integration of time as a fourth dimension complicates our understanding of spatial relationships.
Most of us learned as children that the quickest route is a straight line, a foundational lesson that informs our understanding of dimensions and distance.
In flat space, a straight line represents the shortest path, but in the complexity of spacetime, this principle no longer holds true as dimensions interact.
