What part of black holes sucking things is metaphorical?

[โ€“] [email protected] 5 points 1 year ago

Does gravity suck? Or is it attractive? We say vacuum sucks but in space the (mostly) vacuum is all around. A black hole has less vacuum per cubic inch (or whatever unit) than the space around it, doesn't it?
