minus-square@[email protected]linkfedilink3•1 year agoProbably relative to the CMB (the frame of reference where there is no redshift or blueshift bias in any direction).
minus-square@[email protected]linkfedilink2•1 year agoThank you! At that scale the simpler answers just don’t feel sufficient
minus-square@[email protected]linkfedilink2•1 year agoAt that speed, relative to most nearby large object
minus-square@[email protected]linkfedilink2•1 year agoBut 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.
minus-square@[email protected]linkfedilink1•1 year agoNo other large object will be moving close to that speed so it’ll be almost like they are standing still.
Relative to what exactly?

Relative to their point of origin.
