You have definitely never read any paper about astronomy, or the history
of astronomy. As a matter of fact one of the main issue in astronomy is
to determine the distance of objects as precisely as possible.

And for amusement: noting different delays of quasar fluctuations,

Sure, the delay is known.

The difference in time is actually HUGE, hence you would need to wait a VERY long time, if you want to know the present position of stars seen a few billion light years away.

 Q. How to know what week day and month day will tomorrow be ?

 Oh, stinker Python is opening its muzzle again,
and trying again to pretend he knows something.
Tell me, poor stinker, have you already  learnt
what a function is? Are you still trying
to determine its properties applying a French
