Is the study of black holes using entanglement practical?

In summary, the particle on Earth will still be affected by the entangled particle when it dives into the black hole.

That is, entangling two particles and sending one off in a controlled manner (i'm not sure if we're sophisticated enough to even contain a particle in a quantum state without interference so please fill me in) to a black hole and then observing the entangled particle that we kept in some lab on Earth.

The thing with entanglement, is that it still doesn't transmit information.

So what would happen to the particle on Earth when its entangled partner dives in a black hole?
 
  • #4
Why would you expect something to happen?
 
  • #5
If the particles are entangled, isn't there "spooky action at a distance" in that if you act on one, the other instantaneously is affected before they lose their quantum state?
 
  • #6
The affection is spooky in the sense that you need to compare measurement results from *both* particles to see it.

Will the entangled particle falling into the black hole ever pass completely through the event horizon relative to the observer's frame of reference?

At first you'd think not, but then "event horizon" is a funny concept: no reason the particle can't be placed at the centre of a star before it collapses (or else just send significantly more mass after the particle so that, in the distant observer's frame, the event horizon moves further out and encompasses the particle). So that isn't the problem.

spooky action at a distance doesn't mean if you move one particle it will move the other. It just means that if you measure both particle's independently they will have some guaranteed relation. For example, if you take two electrons in the ground state of an atom. They are both in the superposition state that is 50% spin up and 50% spin down. If you measure one electron to be spin up, the other one instantly becomes spin down. However, you can not transmit information this way.
 

FAQ: Is the study of black holes using entanglement practical?

What is the significance of studying black holes using entanglement?

The study of black holes using entanglement is significant because it allows us to better understand the properties and behavior of these mysterious objects. It also has potential applications in fields such as quantum computing and gravity research.

Can entanglement be used to gather information about black holes?

Yes, entanglement can be used as a tool to gather information about black holes. By studying the entanglement between particles near a black hole and particles outside of it, we can gain insights into the properties of the black hole, such as its mass and spin.

How does entanglement relate to the event horizon of a black hole?

Entanglement plays a role in the event horizon of a black hole because it allows for the transfer of information from inside the black hole to the outside. This is due to the entangled particles being connected and influenced by each other, even if they are separated by the event horizon.

Are there any limitations to studying black holes using entanglement?

There are some limitations to studying black holes using entanglement. One limitation is that the information gathered through entanglement is limited to the particles that are entangled, so it may not provide a complete understanding of the black hole. Additionally, the technology and resources needed for entanglement experiments can be difficult and expensive to obtain.

How could the study of black holes using entanglement impact our understanding of the universe?

The study of black holes using entanglement has the potential to greatly impact our understanding of the universe. By providing new insights into the behavior of black holes, it can help us refine and improve our current theories of gravity and the nature of space-time. It may also lead to advancements in technology, such as quantum communication and computing, which could further expand our understanding of the universe.
