Answer 1

Answer:

Space-time is a mathematical model that joins space and time into a single idea called a continuum. ... But in a relativistic universe, time cannot be separated from the three dimensions of space. This is because the observed rate at which time passes depends on an object's velocity relative to the observer.

Answer 2

Answer:

spacetime is any mathematical model which fuses the three dimensions of space and the one dimension of time into a single four-dimensional manifold.

Explanation:

Spacetime diagrams can be used to visualize relativistic effects, such as why different observers perceive differently where and when events occur.
