what is mean infinite mass explained?​

Answer 1

Answer:

First Mass doesn't converted into energy or small particles.

when an object or something travels at the speed of light. Its mass becomes infinite and when there is a need of infinte enery to travel it at that speed which is not possible.

So, It is not possible to travel at the speed of light specially by train.

Infinite Mass :- There is no limit of mass (in standard unit) to express by any means , then we call it infinite mass.
