Zooming Black Holes Can Reach ~10% The Speed of Light, Scientists Say

ToroidalX, 10 months ago

I can’t even fathom something like this. There’s so much energy involved. Can you imagine how bright matter around the black hole is? And there’s people who believe reaching relativistic speeds will be possible soon…

Black holes aren’t luminous except when matter is falling into the event horizon. So unless one of these was tearing through a nebula we probably wouldn’t see it.

Relative to what exactly?

teft, 10 months ago

Relative to their point of origin.

At that speed, relative to most nearby large object

mookulator, 10 months ago

But what if all nearby objects are moving towards it at a similar speed? Or away? At such a large scale speed becomes a mind bending thing.

dudinax, 10 months ago

No other large object will be moving close to that speed so it’ll be almost like they are standing still.

Probably relative to the CMB (the frame of reference where there is no redshift or blueshift bias in any direction).

mookulator, 10 months ago

Thank you! At that scale the simpler answers just don’t feel sufficient

What would cause them to move so quickly?

teft, 10 months ago

Colliding with another black hole.
