Relative to what exactly?

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

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

[–] teft@startrek.website 2 points 1 year ago

Relative to their point of origin.

At that speed, relative to most nearby large object

[–] mookulator@mander.xyz 1 points 1 year ago (1 children)

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@programming.dev 1 points 1 year ago

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