Pulling information out of a black hole

In summary, the conversation discusses the idea of using a larger black hole to extract information from a smaller black hole due to the strong gravity of black holes. However, the idea is dismissed as two black holes would just merge into a larger one.

Can somebody help me out here.

The gravity of a black hole is so strong that nothing can escape it, not even light. If that's the case, why can't another black hole of larger mass be used to extract information from the first black hole? Sort of like how a Siphon works. I imagine some sort of pathway between the 2 composed of matter somehow.

To be blunt, that's ridiculous. Two black holes near each other just merge into a bigger black hole.
 

1. How is information pulled out of a black hole?

Currently, there is no known way to directly pull information out of a black hole. The intense gravity and curvature of space-time make it nearly impossible for anything, including light, to escape once it has crossed the event horizon. However, some theories suggest that information may be encoded in the Hawking radiation emitted by black holes.

2. Can we recover information that has entered a black hole?

According to the principle of black hole complementarity, information that enters a black hole is not lost, but is instead encoded in the event horizon. However, this is still a topic of debate among scientists, and there is currently no definitive answer.

3. Is it possible to send information into a black hole?

Yes, it is possible to send information into a black hole, but it will never be able to be retrieved. Anything that crosses the event horizon is trapped inside the black hole, unable to escape its gravity.

4. What happens to information inside a black hole?

According to the theory of general relativity, information that enters a black hole is crushed into a singularity at the center. However, this conflicts with the laws of quantum mechanics, which state that information cannot be destroyed. This is known as the black hole information paradox, and it is still a topic of ongoing research.

5. Can we use black holes to travel through time or to other dimensions?

While science fiction often portrays black holes as portals to other dimensions or as a means of time travel, there is currently no evidence to support these ideas. In fact, the extreme gravitational forces of a black hole would likely rip apart anything that attempted to pass through it, making it an impossible method of transportation.
