Could Entanglement Transmit Data Out of a Blackhole?

[Voyager55]

Could quantum entanglement be used to transmit data from within a blackhole? I don't know too much about physics, what I do know comes from high school, KSP, and a deep interest in the subject.

[Neil1993]

Quantum entaglement can't transmit useful data at all.

The principle states that entangled particles will have opposite (I think it was opposite) spins when one is observed and the function collapses, but you can't control what the spin of the particle will be when the state of superposition collapses which means that you can't control the message being sent.

(fact check me; I'm probably messing something up)

^This apparently. I know nothing on the subject but a

video spoiled about half a dozen sci-fi plots for me

In my completely layman understanding of black holes, I would predict at least two problems.

1. The data would have to be sent from a functioning something, pod, drone, etc. Therefore it would have to remain functional as it entered the black hole, which seems highly unlikely while being ripped apart at an (sub?)atomic level.

2. The closer you got to the event horizon, the more dilated time would become. Should your probe survive condition one, any events it encountered would be taking place so far in OUR perceptible future that nobody would be around to get the transmission.

Both of these assume you did mean past the event horizon by "within".

Although we cannot receive transmissions DIRECTLY from a black hole, we CAN receive data by studying what gets thrown out as the black hole "feeds"

Just out of curiosity, have you seen interstellar recently?

You can not transmit usefull information using Entanglement particles.

In case of black holes, well... I dont understand the requirements to avoid the information paradox to see if this type of "data" is enoght.. Scientist are jumping between theories without much care just to get rid of this paradox.

AFAIK, it's not a requirement, but a preference that no data is ever destroyed. However we do seem to have an edge case with black holes, as we can argue that to certain perspectives nothing ever reaches the black hole (it takes "infinite time"). However from other reference frames it does reach the black hole event horizon. So it's still a little undecided if and what information enters or exists black holes.

PS, I must look up how furry black holes are again.

Theoretically "you" should be able to enter the event horizon of a supermassive black hole, since... to quote from wiki:

Supermassive black holes have properties which distinguish them from lower-mass classifications. First, the average density of a supermassive black hole (defined as the mass of the black hole divided by the volume within its Schwarzschild radius) can be less than the density of water in the case of some supermassive black holes. This is because the Schwarzschild radius is directly proportional to mass, while density is inversely proportional to the volume. Since the volume of a spherical object (such as the event horizon of a non-rotating black hole) is directly proportional to the cube of the radius, the density of a black hole is inversely proportional to the square of the mass, and thus higher mass black holes have lower average density. In addition, the tidal forces in the vicinity of the event horizon are significantly weaker for massive black holes. As with density, the tidal force on a body at the event horizon is inversely proportional to the square of the mass: a person on the surface of the Earth and one at the event horizon of a 10 million M☉ black hole experience about the same tidal force between their head and feet. Unlike with stellar mass black holes, one would not experience significant tidal force until very deep into the black hole.

It doesn't solve any of the other questions tho...

Atleast it wasn't brown dwarves... Derp...

When someone mentions furry black holes I always think of this:

Though it's the wrong type of space fur!
