Can Electromagnetic Radiation orbit strong gravitational fields?

Question

Light has mass is it possible for it to orbit very large gravitational fields.

Answer 1

If you are asking "Can photons of EM radiation orbit a strong gravitational field?", then the answer is yes they can.

There is a critical distance from a black hole that is defined by this very property. It is the distance where a photon would neither escape not be consumed, but would orbit. The set of all such points around a black hole is called the "Photon sphere" of the black hole.

The Photon sphere of a black hole has 1.5 times the radius of the black hole's Event Horizon.

Answer 2

Theoretically it should be possible, maybe around a black hole which has a very large graivtiy field.

Ordinarily though radiation is traveling at the speed of light and gravity doesn't affect it very much.

Answer 3

truly? The Luminous skill field has been shown by using technology has it? EMR on the different hand is basically a by using-made from utilising electrical energy, which our physique does. EDIT: you have positioned the poultry till now the egg. our bodies use electrical energy for neural impulse transmission, this creates an electromagnetic field. This dissipates because of the fact we are ineffective.

Answer 4

Light only has "relativistic mass" , it has no "rest mass" which is mass as we normally think about it. To answer your question, yes light can orbit in very extreme relativistic enviroments.

Answer 5

Light doesn't have mass, but it is affected by gravity - that's one of the major predictions of General Relativity. That's also why black holes are "black" - their pull of gravity is so strong that not even light can escape.
