Question

Help answer this question below.

would entangled particles be a good method of measuring what happens in a black hole?

Suppose you had some entangled particles and you aimed one in the direction of a black hole(assuming you could get to one) and measured the effects on the other one once sufficient time had elapsed that you could reasonably assume that the other one was in the black hole. Would you be able to gain any useful information from this experiment? You could repeat the experiment at different time scales as well.

    I think you are misunderstanding entanglement. The experiment, done with twin protons, demonstrated that if you know the spin of one of them, you know the spin of the other even if they are moving away from each other at the speed of light. They cannot possibly be communicating with each other by any normal means, yet each "knows" what the other is doing. You cannot "use" entangled particles because there is no such thing as particles that are not entangled. Everything is entangled all the time.

    What makes this really interesting is when you take the observer effect into account because the spinning protons literally don't exist as spinning protons until they're observed. Both spinning protons are created at the same time by observation. What is doing the observing? Good question. That has not been decided. It can't be from the universe we already know because all of it is affected by observation.

    As far as anyone can tell, this instantaneous communication occurs regardless of distance or obstructions. It is unlikely to be affected by a black hole because the information does not travel. It simultaneously occurs in both places at once.
    This is believed to be demonstrating that there is an unknown connection of some sort between everything in the universe. That is to say, everything is entangled.

    As far as I know, no information can escape a black hole at all. Once your entangled particle passes the event horizon, I would guess that its entanglement would cease to exist. You should look up hawking radiation though...

    if your could get the info From my info the black hole is just a black hole completely nothing in it If it possible to get that info would be great.

    I think entanglement only means that two particles would mirror each other's movements when fired, due to the energy at the begining of the process having the same efect on both particles, and not because the particles are actually connected in any way.

    I believe it's tied into the uncertianty principle (that merely states) that we can't know the exact position and momentum of a particle without interacting with it in such a way that would change those values. Then there's a bunch of mathmatical formulas that would let you calculate a probability of positions / momentums lost by interacting with the particle.

    I'm not %100 certain as I havn't done a tremendous ammount of research on the subject, but I do know there is a common mysticism about quantum mechanics that is flat out wrong.

    So to answer your question: No. The black hole would interact with one particle, and would have no effect on the other.

    The best way would be to use dark matter to find out what is in a black hole. Since dark matter can go through anything, why not a black hole?


    Good luck. And God bless.

    Here is my thought experiment. You get 2 pair of particles. You then build a device that could detect the change in one particle's spin, then upon that change it would then change the spin of another particle. Labeling the 2 pair of entangled particles as A1-A2 and B1-B2. Take A2 and B2 then place them in the device. Send that device past the event horizon. Now change the spin of A1, will B1 change? What would happen??? That's what I wonder. Well, that's my five minutes of geekness.

    No, because entangled particles cannot be used to transmit information. You cannot influence one and expect to see the results of that influence in the other.

    They only share common randomness.
