pervect, Thanks ! I appreciate this 'in-depth' overview. I have done basic undergrad work in physics, mostly to satisfy pre reqs, decades ago. I briefly considered a Math/Physics major (like Planck time briefly ;) ) but I don't think the world would've wanted a lousy (unemployed) physicist...

To follow up, I have been trying to learn the math around BH, to try and develop my own conclusions. Where I started is Einstein’s field equations and am currently meandering through tensor world. The equations indicate that the curvature of spacetime is dependent on the mass and energy...

I returned this to this question earlier this year, and I wanted to add another nuance for your consideration. Let's say that this 'sheet of paper' can be influenced by a magnetic field. If the black hole has a magnetic field (separately, do/should all BHs have a magnetic field?) would a...

(This is an observation, not a complaint. ) As I examine these ideas , every insight I gain spurs more questions about relationships between entities, which (seems like it) can’t be answered by just knowing some facts. I’m realizing that to really make inferences , a good understanding of the...

You folks have put a lot of good information and I have been working through some of it. But I can't do the advanced math bits, so you'll hopefully overlook my naivety when it comes to that. I looked at the Flamm paraboloid , and I think I have rudimentary understanding how the 'paper' will be...

OK, I'm making an assumption. So let me start at the beginning. If I have a large sheet of paper, in 'neutral' space, all is fine. As this sheet draws near to a BH something happens to this sheet. What happens to it? (I assumed it would start bending and breaking apart).

I have been following this thread with great interest. The details that people went into over what I initially thought was a simple question was surprising to me and trying to grasp some of the stuff require some heavy lifting. (Please note my background, I’m a mere layman). Many of your...

thanks, this is good information. I'll work through the Flamm paraboloid writeup. One last question, if we can't interpret the data well enough that comes from curved space time, would it also be the case that we can't get usable data (about spacetime curvature) from light that comes as a...

Thanks, the sphere example is a nice illustration. Please allow me to probe into your answers a bit. (If you wouldn't mind sticking to the 2D world, it just helps me visualize things a bit better.) Let's extend the example, to say that I have a large sheet of paper, say earth sized, bumping...

I asked a question here, probably over 15 years ago on entanglement and I appreciated the thoughtful answers I received back then. The intervening years haven't made me any more knowledgeable in physics, so forgive my naïveté ! If a have a piece of paper in an area of high gravity, lets say...

Hello, I have an interest in QM, and a newbie here, so please bear with me while I attempt to (naively perhaps) ask my questions. I didn't think my questions merited a new topic. If entanglement occurs, can that happen between more than two particles? If two particles get entangled...
