colly0410 1,181 Posted September 10, 2021 Author Report Share Posted September 10, 2021 In New Scientist that they've discovered that black holes exert a very tiny pressure. They've discovered this by incorporating quantum field theory with general relativity & viola = up pops pressure... Probably a bit more complicated than my description: I make it sound like they chucked quantum field theory & general relativity into a food mixer & turned it on, I'm guessing that is not what they did. They actually used a supercomputer & scientific noggin to work it out... Quote Link to post Share on other sites
colly0410 1,181 Posted November 11, 2021 Author Report Share Posted November 11, 2021 The boffins are speculating that there could be a mini black hole in an orbit round the sun further out than Pluto, It would be about 5 to 15 times the mass of the sun & it's event horizon would be about the size of a grapefruit. They know there is a gravitational discrepancy in the orbit of Pluto but they can't see whats causing it. Of course a black hole would be - er - black so they wouldn't be able to see it would they? How they are going to prove this black hole exists I haven't got a clue, but I love these scientific speculations... Quote Link to post Share on other sites
Jill Sparrow 10,307 Posted November 11, 2021 Report Share Posted November 11, 2021 But then it's easier to prove that a black hole exists than to prove a black hole doesn't exist. Absence of evidence is not evidence of absence, as they say! 1 Quote Link to post Share on other sites

Google is your friend: A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole 1 Quote Link to post Share on other sites
Cliff Ton 10,467 Posted November 11, 2021 Report Share Posted November 11, 2021 I thought one of the ways black holes can be detected is that other objects are moving around something which can't be seen......and that something could be a black hole. 1 Quote Link to post Share on other sites
Beekay 5,149 Posted November 13, 2021 Report Share Posted November 13, 2021 Google might be me friend Brew, but it's still all to deep for me. The only black hole I know is the one I worked down at Bestwood. 1 1 Quote Link to post Share on other sites
Brew 5,418 Posted November 13, 2021 Report Share Posted November 13, 2021 It's all relatively simple BK, just remember the singularity at the center of a black hole doesn't actually exist... 1 Quote Link to post Share on other sites
Jill Sparrow 10,307 Posted November 13, 2021 Report Share Posted November 13, 2021 It's rather like the philosophical concept that any object which does not exist infers an identical object which DOES exist. Arrived at by St Thomas Aquinas...or it might have been St Anselm. Thus, a polo mint has nothing at its centre. Yet if you can stick your tongue through its centre while you're eating it, it must have physical space there or you would not be able to do so! Therefore, just think of black holes as black polo mints...now there's a diverse and equal opps niche market for some Enterprising (pun intended) person to exploit. 1 Quote Link to post Share on other sites

colly0410 1,181 Posted November 22, 2021 Author Report Share Posted November 22, 2021 There has been over 1,600 Fast Radio Bursts (FRB's) in 47 days from the same part of space. No one knows what is causing these FRB's, of course aliens have come up, but they speculate that it's more likely to be a magetar behaving in a strange way never seen before. I so love these scientific mysteries, & long may they continue... Quote Link to post Share on other sites
