What happens to two entangled quantum particles when one crosses an event horizon?

What happens to two entangled quantum particles when one crosses an event horizon of a black hole? Would they remain entangled?

In theory, whatever happens to one particle is reflected in the other. However, since the particle wouldn't cease to exist until it may be radiated as Hawking's radiation, likely nothing would happen. You also can't ignore de-coherence, which would un-entangle the particles.
What then?

1 would think so as distance may not be a factor in their entangled connections...

Wasn't an "exit" on the other side of a black hole in one of the theory's? I vaguely remember something along the lines of a very fine particle stream shooting out from the opposite side. Could that be anti-matter and be what ultimately makes up the fabric of space, the reason why there is even entanglement in the first place?

they become un-entangled? i was just watching the Red Sea Crossing and thought that would be the only thing that should be expected.

Hawking is confused, he's well past his prime if he even had one.

No Black Holes

And of course if there can be no black holes, because there is no event horizon, then there can be no hawking radiation LOL. The whole theory is kinda bunk anyway, both particles would fall into the black hole since one is attracted through mass and the other through charge.

I gotsta get me one of them new fangled glow-in-the-dark black holes ;-)

wow...just wow.

even ramses confessed eventually. now you say there is no event horizon, no singularities?

i bet you consider ramses to have been a chicken.

ya'll are really taking this is far as you can.

you must be a bot or AI or surely you know eventually...you will deny your own existence.

Er.... wtf are you all talking about?

Well we were talking about science and then someone brought up moses. Because........derp.

I have to agree. One cannot equate the splitting of a body of water, which is a feat of epic badassery to be sure, with a hypothetical involving quantum entangled particle interaction with an event horizon.

As for what would happen, I have no idea. But I would love to see someone develop an experiment which might give us a clue!

I'm not sure if any one actually knows the answer. This is a great question and one that would need precise mathematics to divine. My guess, given that entangled particles have the seeming ability to react to each other with near instant speeds that even if event horizons are the case then those particles would still react the same.

If that is the case, then that could possibly maybe be used way far in the future to transmit signals and thus explore "black/grey holes" or whatever they are now.

a reply to: Woodcarver

ramses and moses were two entangled quantum particles and one crossed an event horizon...OP wanted to know what happens to the other.

i think the second particle will attempt to cross but be obliterated.

i'm pretty sure i know more about this branch of science that you do.

accept a little help when its offered why don't you?

or you can perform an experiment of your own that doesn't involve repeating someone else's work.

just because you just regurgitate concepts from a text book doesn't mean that everyone else did.

I have already denied my own "existence" at least as far as being real within this virtual reality construct. But I did have to type that since I am simply riding a "meat puppet" bus and have no free will ;-)

Now as far as the Hawking comment, Hawking actually denied the existence of black holes recently, that was of course long after he said his theory of Hawking Radiation was wrong LOL.

ETA, on your expertise, I have worked with the NRC, universities and the military all in R&D, usually project lead or chief. I have my own adiabatic reactor for BEC research and created a pair monopoles (still under study at the university) to examine EPR and ER concepts in spatial compression theory (solutions to EPR/ER/BEC in entanglement and particle degeneracy).

I was expecting an answer to the question.



I want my click back.

a reply to: bobs_uruncle

but he didn't deny the existence of singularities other than black holes.

when i read 'black hole' i assume that the author means any type of singularity...

nevertheless, applying the theory to real things would be more helpful if you want anything to make sense.

denying the event horizon and singularities ultimately leads to denying your existence. as both of these things are quite obviously real.

a reply to: michaelbrux

Regurgitate?

Uh huh...

If you say so.

But however I come by what I know is rather immaterial to the point I was making, which is that you cannot in fairness compare the scenario that you used in your post, with the situation hypothesised by the OP, because they have absolutely no common features what so ever. Moses and quantum entanglement are as totally different to one another as baked potatoes and nuclear weapons.

Then you are saying that this virtual reality is real and that you exist in this alleged reality rather than "observe" via some entangled particles tethered to someplace else (sideways or otherwise)? Can you prove that?

I'm just a dumb layman, but what he said.

If the gravity and crushing mass of the black hole doesn't untangle them then theoretically speaking shouldn't this be a great opportunity to take advantage of QT properties to somehow transmit data back to us from within.......and beyond!

a reply to: TrueBrit

moses and ramses are two quantum particles, gravitational singularities to be specific.

one crosses an event horizon, called the Red Sea in the popular story, and he took three women with him (the Standard Model)...what happens to the other; he tries to cross and he is destroyed...

this is quite straight forward. sorry that i've decided to interpret the story as a thought experiment into the type of questions the OP asked.

i started doing it after I saw that the development of quantum mechanics coincided with the destruction of nearly every King and Emperor in WWI.

but maybe your theory is right...that people have to be handy with a firearm...aka Monkey World.
