Black Hole?

Question

If time gradually slows down to the point of matter or time never reaching a black hole. What is in a black hole? What speed does "time" travel?

Answer 1

The remains of the star that formed the black hole are "inside" it. Basically, it's just a bunch of star matter collapsed into an infinitesimally small point.

The passage of time for something moving at close to the speed of light is less than that of something sitting still. From the perspective of a stationary observer, time seems to be passing very slowly for the high-speed traveler, but their own time is passing normally. From the perspective of the high-speed traveler, time is passing very quickly for the stationary observer, but their own time is passing normally.

Someone very close to a black hole, assuming they could survive, would experience their own passage of time normally. An observer looking from some distance away would see time passing very slowly for the person near the black hole.

Answer 2

Remember this statement:
It's all relative.

Time only slows down based on relative observations. For a person falling into a black hole, time always seems to be passing at 1 second per second, nowhere in the universe can any observer say anything different. People observing the poor schmuck caught by the black hole would think that his time was slowing (for example, he sends out a signal every second and in his personal time frame they are evenly spaced, from a distant observer's perspective the messages would appear to get farther and farther spaced out until they never receive a signal).

As for what's "in" a black hole (by which I assume you mean the event horizon of a black hole), nobody can tell you. One of the points of a black hole is that nothing can escape, matter, energy, light, and most importantly, information (which encompasses all of the previous options). So we can't know what's in a black hole's event horizon, we're limited by physical laws.

Oh, yeah, and time doesn't travel, and it certainly doesn't have a speed. Closest thing I've ever heard to that suggestion is an "update" rate like that on a computer screen. Always one second per second.

Answer 3

Any matter that comes close enough to a black hole to be attracted by it's gravitation will quickly speed up as it gets closer to the black hole. The force of gravity near the surface of a black hole is so powerful that a human being would be pulled apart atom by atom as his body entered the event horizon of the black hole and his body would go into the black hole as a string of atoms. It's strange that other answerer's did not state what the contents of a black is. All matter in the universe consists of protons, neutrons and electrons, by far, the majority of the mass is in the protons and the slightly heavier neutron, that is what is inside a black hole, protons and neutrons. These particles are so densely packed together due the crushing gravity involved that there is no room for movement, therefore no room for events, hence the name event horizon for the beginning of the body of the black hole, no events take place once matter is inside that horizon. Time is an interval between events, no events, no time. As for the movement of time, it is my opinion that it must move with the events that continually take place, the rate of this movement can't be stated in inches or miles per anything but move it must. I hope this has been of help

Answer 4

If you and a clock you carried could somehow survive a trip into a black hole, the clock would continue to show time moving along at the same rate as it always has.

However, if someone could somehow observe your clock as it moved deeper and deeper into the black hole it would appear that the clock was running slower and slower.

This effect was theorized by Einstein and it's been confirmed over and over again by experiment.

Another thing that Einstein showed us is that time itself is not a *natural* feature of the universe. What we perceive as time is nothing more than a concept developed by our species to separate events into 'past,' 'present,' and 'future.' The main thing to understand though is that there's no such thing as a kind of Cosmic Master Clock that ticks off the correct time for the entire universe. To simplify this whole idea, right now it's 6:00 pm on the West Coast. In New York 9:00 pm. Which time is the correct one?
