Stopping Time for a region of space

If we take a region of space bound by certain x,y, and z co ordinates and manage to stop time in there, wouldn't this be a singularity of un precedented proportions, in the sense that everything will become instantaneous and all our known laws and equations will break down? IMO it will be a singularity where nothing can be gauged from our time bound existence. Just wondering what every1's take is on this subject.
Thanks in advance.

Who said that this doesnt happen ? Is it possible that time actually stops in the singularity of a black hole. With a gravitational influence enough to bend the space/time fabric as much as it does just past the event horizon , imagine what it could do further down the well ? Completely rip the fabric as to where no laws of science apply ?

Great question.(at least it isnt about politics or global warming)

imo time speeds up with gravity, which is opposite to GR and in the black hole singularity time runs infinitely quickly, which is also a singularity

In 1949, Kurt Gödel produced a solution for General Relativity that allowed for closed time-like curves, where the flow of time would cause an event to return to its starting point.

Since then other solutions have been found that 'loop', too.

As these solutions allow time to be traversed negatively (going back in time), there has been a suggestion that they only exist in theory and Quantum Gravity theory will eliminate them (also replacing GR) or that there will be another add-on theory that Hawking calls the "chronology protection conjecture".

Perhaps that is an answer to what you were asking, a specific closed time like curve of zero duration?

I think it happens often. And I like Gothmog's description. I once wrote a paper on time being a particle and it's behavior at the event horizon of a black hole.

temporal cloaking has been done in a lab just recently

Thanks for taking the time to contribute such comprehensible explanations for what are really complex and often mind bendingly counterintuitive ideas and phenomena.

I'm sure I am not alone in saying that I have learned a lot from your posts explaining topics like theoretical physics and quantum mechanics.

As an extension, consider being near such an area of space and having for example a solid metal rod which was larger than any single dimension of the time-frozen space...

If you chopped through this area of space in sword-fashion, what would happen to the metal rod? Would it impact the surface of the time-frozen area? Would it trap that part of the rod outside of time? Would the universe cease to exist in a spectactular way, but immediately be replaced by a different universe where the laws governing such interactions include a loophole?

In order for time to stand still it would mean that the space would need to stop expanding and for there to be no production of particles from the quantum vacuum, is that right? Wouldn't that be silly hard to achieve? How could that happen?

Would you be able to traverse a space with absolutely no motion in it?

I don't know because I don't understand the intricacies, but it sounds like an impossibility to me.

Would love someone to explain it if poss though.

But it has been proven beyond a doubt time goes slower in a gravity well.

Just by going into earth orbit time changes, as proved by 2 identical extremely accurate time pieces being synchronised, then one sent into orbit, and the other left here in earth.

They know this to be true, because they have to set the clicks on GPS satellites accordingly , otherwise your GPS wouldn't work.

Perhaps a closed time like curve of zero temporal duration is a singularity of sorts.

Anything entering the affected space would be 'frozen in time' according the captured object's reference frame and therefore would likely be captured inescapably.

From an external reference frame, where time proceeds apparently linearly, perhaps the looped space-time itself could shrink or cease to exist as external conditions required for the loop, changed. This would release any trapped objects from their temporal prison.

That leads back to us asking questions about the conditions that could possibly cause such a curve.

In some cases, the curve creating construct would be highly artificial but in several cases, it could be caused by a rotating black hole (we have evidence that such things could exist beyond pure theory).

In most cases, the arguments for the creation of any black hole implies that it would not form instantaneously. It would exist by a process of gravitational collapse, over time. If such is the case, Coriolis forces and its previous stellar momentum would cause the initial rotation of a proto-black hole. This spin, like a ballet dancer spinning in a pirouette, would accelerate in angular velocity as the outer diameter reduced in the collapse. So in all likelihood, ALL black holes would be rotating.

This gives us consistency between different theoretical views of gravitational singularities' details and may suggest that, once a gravitational singularity has established, any in-falling mass would become 'time locked' in it.

This also may define the internals of a black hole as a series of 'shells' left behind as the Schwarzschild radius (or event horizon) expands. The in-falling matter would always remain in-falling, in one sense, but would truly be stopped at the event horizon (in all reference frames) until the freeze on its 'time' is lifted.

One thing that may release stuff from the temporal freeze would be the reduction of the event horizon's diameter, and this reduction is likely to be due to gradual 'evaporation' due to Hawking radiation.

So not only is some information stored about matter falling into a black hole, so is some of its temporal detail stored in the matter's positional shell level.

Not according to Einstein and many popular theories on black holes today.Per these theories if an object passes the event horizon and you were watching , you would see that object suspended in time for eternity .

Does time exists?
Time is just an abstraction, close to an imagination imo. Universal time don't exist, there is only Solar System-time that we invented but never measured. It's not a real 'thing' just a concept.
I believe time doesn't exist and it has no place in or privilege to call itself a dimension.

So to answer your question if you stop time somewhere, nature will just do it's thing as it has been doing before we removed the battery from our watch.

negating time negates gravity owing to the equation e = mc2, so GR ought to be wrong
