Discussion Overview

The discussion revolves around the concept of time in relation to black holes, specifically whether it is possible for time to completely stop in such extreme gravitational environments. Participants explore various aspects of black hole physics, including the nature of gravity at the event horizon and the singularity, as well as implications for information and radiation associated with black holes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant proposes the idea of a bubble where time stops, linking this to the properties of black holes and suggesting that time slows down as one approaches a black hole due to increasing gravity.
  • Another participant challenges the notion that time stops at the event horizon, asserting that gravity is not infinite there, but only at the singularity.
  • Questions arise about the nature of gravity at the event horizon versus the singularity, with some participants seeking clarification on the differences between these concepts.
  • There is a discussion about the inverse square law of gravity, with participants attempting to understand how gravity behaves at different distances from a massive body.
  • One participant expresses confusion regarding the implications of information being trapped in a black hole versus being expelled as radiation, referencing a debate involving Stephen Hawking.
  • A later reply points out a common paradox regarding the concept of time stopping at the event horizon and the implications for objects falling into a black hole.

Areas of Agreement / Disagreement

Participants express disagreement regarding the nature of gravity at the event horizon and the singularity, with no consensus reached on whether time can stop in a black hole or the implications of this for information and radiation.

Contextual Notes

Participants demonstrate varying levels of understanding of black hole physics, with some expressing uncertainty about fundamental concepts and equations related to gravity and time. There are unresolved questions about the definitions and implications of singularities and event horizons.

Who May Find This Useful

This discussion may be of interest to those exploring concepts in astrophysics, general relativity, and the nature of time and gravity, particularly students and enthusiasts seeking to understand black hole phenomena.

hello, I am new to this forum so I am not sure if this is the right spot for me to post my idea, but here it is. :smile:

i was talking to a friend about different questions about how things work when he asked the fallowing question: "is it possible to creat a bubble where time completely stops?" i told him i didint think so, so i tried to explain why when a thought came to me. it was of black holes. from what i have heard on tv and what i have read about black holes, the closer you get to them, the slower time goes. this is because of gravity getting stronger correct? so since the black hole itself is of infinite gravity, does that mean that where the black hole itself is, time would stop? if this is so, when something would enter into a black hole, it would not be expelled as radiation, it would be frozen in time in the black hole. if this is true, this would also mean that black holes would expand right? everything would keep piling on top of everything else. everything that is added on would then increase the gravity and expand the time difference. it would also explain why light can't escape. it couldn't advance because it is frozen in time.

again I am new to this so some of this info might be off, but is this possible?:shy::confused::smile:

time stops at the event horizon and gravity isn't even infinite there

what do you mean?
 
what do you mean 'what you you mean'?
I mean exactly what I mean.
 
how can gravity stop being infinite? are you saying that gravity doesn't exist in a black hole? that doesn't make sense.
 
the gravity at the event horizon isn't infinite
it would only be infinite at the singularity
 
why would the gravity not be infinite at the event horizon? also, what's the difference between a singularaty and a black hole? arnt they infinite the same thing?
sorry if these are stupid questions, I am still in school : )
 
gravity follows an inverse square law does it not?
1/02=infinity so its infinite at the singularity
1=r2 for r>0 is not infinite
 
can you tell me what each part of the equation means? what each number represents and each letter? again I am in school, i don't know much about the equations.

it means that the further you are away from a massive body the less its gravity effects you.
 
  • #11
so the area around the black hole has the infinite gravity? is that what you mean?
 
  • #12
gravity is only infinite at exactly the center point of the black hole. At the very singularity itself.

the singularity is infinitely small.

how old are you
what grade are you in
 
  • #13
wait, so does that mean my idea is possible?

i think i might have missunderstude something. i got a lot of this info off of the show through the wormwhole. the part I am not sure about is the debate between stephen hawking and that plumber guy (cant remember his name). stephen hawking said at first that information was destroyed by black holes, but the plumber guy proved him wrong by saying that it was expelled as radiation (i think). the idea of what i am saying is that since the info would be stopped in time, it wouldn't be given off as radiation as this guy said. I am not sure if this is right though.

Gravity is clearly not infinite at the event horizon. And if it were infinitely strong at the singularity, how would it diminish over distance? This paradox is easily resolved if the singularity has a finite volume, however tiny.
