AI Thread Summary
Matter falling into a black hole does not exceed the speed of light but approaches it as it nears the event horizon. Once past the event horizon, defining velocities becomes ambiguous due to the absence of stationary observers. In-falling objects continue moving toward the singularity, rather than stopping. Remote observers perceive these objects as slowing down and appearing to 'freeze' due to gravitational redshift. The behavior of matter in black holes remains a complex topic in relativity.

Does the gravitational force of black holes pull matter in at speeds faster than the speed of light? (when the matter has passed the event horizon that is?)

Or does the matter just stop moving out and in? and stop where it is?

Or do we not know anything about this just yet... which I'm assuming

As in all relativity, when you speak of velocities you must specify with respect to whom you are measuring these velocities. For example, with respect to shell observers, in-falling objects approach the speed of light as they approach the event horizon. Since there are no stationary observers within the EH, defining velocities becomes even more ambiguous. Matter certainly doesn't stop, it is destined to end up at the singularity.
 
Nabeshin is correct. Weirdly enough, remote observers perceive that objects falling into a black hole slow and eventually 'freeze' as they approach the event horizon due to gravitational redshift.
 

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...
