SUMMARY
The discussion focuses on measuring the tangential component of velocity for receding stars and quasars. It is established that redshift measurements only provide the radial component of velocity. For stars, proper motion can be assessed through techniques such as comparing images from different epochs and using high-resolution interferometry. However, measuring the tangential velocity of quasars remains virtually impossible with current technology due to their significant distances.
