    Blackholes Light
AI Thread Summary
Black holes prevent light from escaping due to the curvature of spacetime, not because photons possess mass. The concept of gravity as spacetime curvature explains why light follows a geodesic path. Photons are massless particles, which allows them to travel at the speed of light without violating any physical laws. The discussion emphasizes that the inability of light to escape black holes is unrelated to the mass of photons. Understanding these principles clarifies misconceptions about light and gravity.

If black holes were able to stop light from escaping , then would it mean that photons do have a certain mass (no matter how much negligible it is ) and if it does then how can something that has mass (photons) travel at the speed of light. wouldn't the speed limit aplly to them too?

No, that is not the reason that they cannot escape. Take a look at some of the similar discussions below or ZapperZ's statement in this thread.
This issue has been discussed to death in several threads in both the Quantum physics forum, and the SR/GR forum. Please do your search there and figure out how gravity is a spacetime curvature, and why light follows the "geodesic" of that spacetime curvature. It has NOTHING to do with light having a mass.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
