EIn the sense that we don't expect stress-energy to just disappear, that's true. However, it's also true that we do expect a black hole...
-
EAnd your clarifications showed that your usage was not correct, in the way I pointed out. In that spacetime diagram, an object "at...
-
EIn "realistic" models of collapsing stars in GR, the matter reaches the singularity and leaves our model. Its gravitational effect...
-
EEdwardRo replied to the thread Undergrad Black hole questions.This is fascinating to me. I had it beat into my head that matter and energy cannot be destroyed. When a star collapses, that mass needs...
-
EEdwardRo replied to the thread Undergrad Black hole questions.Yes, like I said, I have a lot of gaps in my knowledge. First, I realized that my nomenclature is wrong. I wanted to clarify what I...
-
ENo. It's not even part of the spacetime. It's not. No, that's not correct. Look at a Kruskal diagram, as seen, for example, in this...
-
EEdwardRo replied to the thread Undergrad Black hole questions.When I say black hole, I'm speaking about the event horizon itself. Singularity is the object within the event horizon, the remnants of...
-
EOn a re-read, are you using "singularity" and "black hole" as synonyms? They're not the same thing. The singularity is inside the black...
-
EEdwardRo replied to the thread Undergrad Black hole questions.Right, the spacetime diagram flips. That part makes sense. And I realized that the math breaks when trying to look past the event...
-
EEdwardRo replied to the thread Undergrad Black hole questions.The event horizon is a feature of spacetime yes. But wouldn't the singularly still be made of something. I know that neutron stars...

ETo start off, please understand that as much as I love physics and try to keep myself immersed in everything, my education in it doesn't...
