Why do black holes attract photons?

A black hole itself does not give off any light. That is why it is called black. However, matter that is near a black hole can give off light in response to the black hole’s gravity. Since light travels in a straight line through straight spacetime, the curving of spacetime causes light to follow a curved path.

Why does light get pulled into a black hole?

When light travels into a black hole it will eventually hit the event horizon, and as spacetime continues to bend into itself; the light will follow. So really, light will never get sucked into black holes. Instead, light is simply following its normal behavior, and traveling straight into black holes on its own!

How do black holes affect photons?

Black holes bend space-time more than anything else in the universe because of their extreme densities. At a certain distance from a black hole’s center, the escape velocity is faster than the speed of light, so photons that come within that distance follow space-time into the black hole and cannot escape.

How can photons attract?

Therefore the answer is yes, photons gravitationally attract each other in General Relativity. The energy of the photons would bend the spacetime in such a way that the photons would get closer to each other. The fact that light deflects in a curved spacetime has been observed.

Why black holes attracted light if photons have no mass?

Surprisingly enough, we see the same thing happen to light, which has no mass. When light passes by black holes, as it shifts in that straight line of space-time, it doesn’t speed up its acceleration, which things with mass would do, because light has a universally constant velocity.

Why can’t photons escape a black hole?

Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. This is the reason why light cannot escape a black hole.

Why black holes attracted light if Photons have no mass?

Why photons Cannot escape a black hole?

Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon. This is the reason why light cannot escape a black hole.

How do photons collide?

However, two photons heading towards each other can indeed collide indirectly. For example, a photon can turn into an electron and an anti-electron. If two photons head towards each other and they both turn into electron/anti-electron pairs at about the same time, then these particles can interact.
