Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our understanding of the world and shape our lives.
Apr 03, 2013 · «If photon has rest mass = 0 , then why does black hole pull it in?» – Karan Karnik «When black holes absorb matter, the matter’s velocity accelerates into the black hole because of …
Black holes have so much mass and zero dimension (aka a singularity) that a small region of spacetime around the singularity has so much curvature that it can trap even massless photons. PS: This page has a nice (faked) representation of what the gravitational lensing might look light around the edge of a …
Photons have no mass, but they can be pulled by the gravitational force generated by a Black Hole. The explanation is a little bit complex and it depends on your understanding of physics, and to …
Apr 14, 2005 · Although they have no rest mass, photons have energy so behave as if they have mass. All things (photons, neutrinos, whatever) are affected by gravity, whether or not the source of the gravity is a black hole or any object with mass.
Feb 09, 2018 · I think OP thought that «photons don’t have mass then how can they be affected by gravity since we can’t put it in the gravitational force equation And the answer is that it’s purely GR, space-time curvature effect, which I tried to explain in my pre-posts.
Apr 10, 2013 · People say,»Nothing can escape black holes, not even light» Then how did light ended up in a black hole? Correct me if I’m wrong.
The gravitational force is related to mass isn’t it? Is there another force in the black hole or does light has mass? This is a great question! You are right that according to Newton’s gravity, the force of gravity on particle that has 0 mass would be zero, and so gravity should not affect light.
We have heard adages like nothing can escape the gravitational pull of a black hole, and we often think of black holes as cosmic vacuum cleaners that can suck up entire galaxies and anything else that has mass.
Mar 18, 2009 · However, if the photon’s path crosses the event horizon, it can never escape. If something with mass, however, passes near a black hole, it will be pulled inwards, and will spiral inwards (perhaps after orbiting it a whole bunch of times). But the behavior is a little different for mass vs. photons; mass is «pulled in», but photons have to
Light is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass. On the other hand, if light does have mass then doesn’t mass become infinitely larger the closer to the speed of light an object travels.
