The gravitational pull of a black hole is so intense that not even light can escape, correct? Einsteins theory of relativity is widely accepted in the community, that Gravity warps space and time. In Einsteins calculations, what effect would a black hole have on time?
It's mind boggling for me. black holes spew out what they have eaten right? Imagine a black hole spewing out time?
Any thoughts on this? |

To an outside observer, time appears to freeze for objects falling into a black hole. In other words if you watch something falling into a black hole it never quite gets there. Instead the light coming from the object gets redder.
The spewing out is overrated. It is significant only for mini black holes. |

The time part is not literally time; not the time as in, "I came home five minutes ago".
I posted a while ago trying to get the idea of time in GR settled, but never really got down to a solid answer....so anyone, feel free to correct me on my definition.
I see time in Einstein's GR as a way of describing change of position on an x-y-z plane. The idea is that if something moves, you can say that it was in its previous position a certain amount of time ago. Therefore, change in position is equal to a distinguishable demonstration of time . Because of this, you can call time somewhat of a sub axis to each x-y-z plane.

Since time is merely a tool we use to measure change, we should focus on the changes as opposed to the tool, as the tool remains the same.
So, a black hole will create changes based on whatever comes in proximity of the black holes remaining properties; spin, charge and mass.

So the idea is that it would only seem like you never fell in to an outside observer because of the light very slowly moving away from the black hole due to the gravity pulling it backwards? And that you would fall in just as it collapsed because of gravitational time dilation?

you have already answered your own question. gravity affect space and time. and also a black hole does not take in space or tiime it just takes in matter. that makes gravity wich affect time. |

come one allready
black holes caneat only your brain cells if you belive in them!

Unfortunately the black holes explode and spray the galaxy with anti=matter particles. Thus the black holes not only eat time but eventually eat us. Nothing will be left of the entire universe as all black holes simultaneously explode. Thus this universe came from nothing and one day in the not too distant future will be completely erased. |

Can you stop this black hole nosesense ?

Sorry, I didn't mean time ticked the same for all observers, I meant time as a tool for measuring changes remains the same.

This is nonsense.
