minus-squaremookulatorlinkfedilinkarrow-up2·1 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-squaredudinax@programming.devlinkfedilinkarrow-up1·1 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?
