AI Thread Summary
Photons are indeed affected by gravity, as they follow the curvature of spacetime created by massive objects. When the escape velocity of a body exceeds the speed of light, photons cannot escape, such as in the case of black holes. Gravitational lensing occurs when light bends around massive objects, creating visual distortions. The discussion clarifies that while gravity influences light, it does so differently than it affects objects with mass. Overall, the interaction between photons and gravity is a fundamental aspect of general relativity.

Some days ago some body posted a question saying are photons effected by gravity but was unanswered straightly. Here is the answer: Yes they are. They will be completely be stopped if an escape velocity of a planet is greater than the speed of light.

First off, its 'photon'. Secondly, light isn't so much "affected" by gravity as it just follows the path of least resistance through space just as any object would. So if gravity were strong enough to form a rather deep gravity well, then light would bend through the path like a marble encountering a dent in the floor it's rolled across. That's how gravitational lensing works. Starlight encounters the gravity well of a rather large mass (star) and follows the curvature of spacetime forming an image of a star blocked from view by the object. A black hole can form a large enough gravity well to pull light beyond the event horizon were it can't escape.
 
really?

I was reading like: If at all a photons tries to escape a black hole in which the escape velocity is higher than the speed of light the photon will never be able to escape. Is that not true? ofcource a photon is bearly affected. Like i said i am telling an answer. What is 9.8 m/s compaered to 3.00*10^8?
 
A black hole, by definition, is a body whose escape velocity is, at some altitude, greater than the speed of light. The mathematical surface surrounding such a body is called an 'event horizon.' On or inside this surface, the escape velocity exceeds c.

And the number 9.8 is not a velocity -- it's an acceleration -- m/s2. You cannot compare a velocity and an acceleration, because they mean different things.

BTW.. "Secondly, light isn't so much "affected" by gravity" this is incorrect it is. see explanantion

good topic!

Well I sort of ment not in the way that gravity affects objects with mass.
 
So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
