Not masses, size. The article says size.
- nathan_compton 4y agoIn the case of a black hole mass and size (radius) are inextricably and linearly linked. All black holes with a given mass have the same radius (modulo a small effect of angular momentum).
- davorak 4y agoI did a rough calc in: https://news.ycombinator.com/item?id=35361280 https://news.ycombinator.com/item?id=35361280 When it was pointed out TON618 has ~66 billion solar masses. But if it is 30 billion times the size of the sun then I think that means it is ~2354000 billion solar masses.
- runnerup 4y agoI believe for black holes the volumetric size is a known function of mass. If you exclude the rest of any Lyman-alpha blob present around the black hole.
- trilbyglens 4y agoMass is the only really meaningful measure of a blackhole, as they occupy a spacial singularity, which is to say, the have no measurable size. The event horizon has a diameter, but that's not the object itself.
- ioblomov 4y agoGuessing that "size" for black holes can mean mass, volume, or radius. But I'm pretty sure the relationship between those three quantities is well defined and directly proportional, so any way you look at it, this thing is incomprehensibly huge.
