Physics, asked by ThayilRuchika, 1 year ago

If photon rest mass is zero and moving mass is indeterminate why it feels gravity?

Answered by UsamaRao

General Relativity says that it is energy that gravitates rather than mass. So while massless particles may have no mass, they have energy.
In general relativity, it's usually not best to think of gravity as a force. Gravity is the result of energy changing the geometry of space-time.
When viewing gravity as geometry, it is much easier to understand how massless particles are influenced under gravity.

ThayilRuchika: are u saying that
Gravity is not depend on mass but it depends on energy But as well as i know the force of gravity also depends on mass And photon has mass while its moving.
There is no existance of massless partical then how it statement be true.

UsamaRao: If any particle not having mass it'll definately posses some amount of energy and mass and energy are inter-convertable

ThayilRuchika: I am talking about photon while its moving its mass is not zero .
