Technically I believe there is still a mass inside it, however, even if it has been crushed to a point. It isn't a "free-floating space warp" which is what Edgar was suggesting (I asked him, to double check, and he affirmed it). If that was possible, then presumably *any* space warp could become detached from its source and "drift off into the aether" ... the Earth might leave a furrow in space behind it as it orbits the Sun, into which dust and asteroids would tumble... There *are* "free-floating space warps", of course, namely gravity waves. But as far as I know, they don't appear to be a major contributor to "dark matter". > > Note that Hawking as just posted a paper casting doubt on their existence: > > http://arxiv.org/abs/1401.5761 > > I will read that with interest, thank you! I have long suspected that black holes don't exist as specified in GR - I mean, that they aren't infinitely dense singularities inside an event horizon. Nice to see Stephen coming round to my way of thinking :-) No, seriously, a lot of alternatives to Black Holes have been suggested, and some even seem quite likely to my poor little brain. Presumably GR breaks down at some point before it reaches infinity (otherwise all your "finitist numerologists" are in trouble :-) -- You received this message because you are subscribed to the Google Groups "Everything List" group.
