We perceive time as a scalar. However, what we perceive as time is a one dimensional projection of multi-dimension phenomenon.

SUMMARY
The discussion centers on the nature of time and speed in the context of general relativity (GR) and gravitational fields. It establishes that the speed of light is not a scalar quantity due to its dependence on direction within a gravitational field. While time can be treated as a scalar in certain contexts, it is more accurately described as a component of a four-vector. The conversation highlights the complexities and varying definitions of scalars and vectors in physics, emphasizing that proper time is invariant while coordinate time is not.
PREREQUISITES- Understanding of general relativity (GR) principles
