Aren't you conflating black holes with singularities, here?
Questions about singularities, I would assume, are inherently non-scientific in the sense that it would be impossible to ever come up with testable predictions about their behaviour. However, black holes, as 'a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it' (definition ripped from Wikipedia), seem like a testable concept with some evidence for their existence.
- dboreham 5y agoThey're the same thing.
- mannerheim 5y agoNo, they are not. For instance, fuzzballs, if they are real, would be black holes from the outside, but not singularities on the inside.
- CRConrad 5y agoSo is this what Fredrik Pohl uses in his Heechee Saga? I always thought that was free fantasizing for the sake of science fiction. https://en.wikipedia.org/wiki/Beyond_the_Blue_Event_Horizon https://en.wikipedia.org/wiki/Beyond_the_Blue_Event_Horizon
- mannerheim 5y agoFuzzballs were first proposed as a consequence of superstring theory in 2002, so it would be quite a feat for a scifi author to have come up with them in 1977.
- CRConrad 5y agoWell, isn't that what being a science fiction author is all about -- predicting the future? :-D But glad to see Pohl was so great at that too, besides the actual craft of writing.
