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...
