Since it's an hypothesis, and nobody know if it's happening, or the mechanism if it is, then sucking is a reasonable word, as good as any other, to describe something that is hypothetical.Forty Two wrote:Well, then your model doesn't include matter sucking in space, which is different than you described. Things flowing into black holes is not just a different way of putting it. It's a different concept altogether. So, to correct your theory, you are eliminating the bit about matter sucking in space.
I would define sucking, as creating a partial vacuum. That might be an apt word for the process, if it's happening at all. Or not. It's a bit pointless getting fixated on a word that doesn't really matter at this stage.
The proposal is that matter causes some space to disappear, either by annihilating it or changing it's form.
Other space then moves in to replace it, and more replaces that, etc etc, radiating outwards as an inward flow of space. If there is no "suck" then there would be no flow. It's just a mental picture, there might be other possible mechanisms. I can't think of any offhand, but I'm willing to take suggestions.
