#589035 — Earth is orbitting Sun

But is it also true "from the point of
view" of an Earth observer?

No, obviously.

But there is worse than that.

Assuming that a body revolves around another at speed v=0.8c, ie at 
relativistic speed.

Well, not only will the rotating body see in its frame of reference the 
other body rotating around it, but the radius will be greater.

R'=R/sqrt(1-v²/c²)

Don't think it just comes out of my sick mind.

No, no, it's just a good understanding of Lorentz transformations well 
understood, and brought to rotating frames of reference.

Obviously, Copernicus wasn't an Earth observer...
How about you?

that was another stupid nazi polakian separatist. Let's hope it goes back 
to the Russian Federation.

no, that's different. Taken from another corner.

do you mean someone who is observing an Earth? from where, the moon or
the sun??

What happend to July 31, 2022, and, why is all the datediff showing up as "now", 
and for that matter is 1.75 seconds difference in the length of a day, really that much?

No, not much. Unlike 38us of the difference
between a GPS satellite real second and
your ISO idiocy.

My obvious mistake, of course - it's only 38us/86400.
Still, it's enough to estimate the real value of your 
ingenious differently ideas.

No, I mean Earth observer - an observer from Earth.

An observer from Earth could very well be on the moon observing the
Earth. 

He would be an observer from Earth, observing Earth.

Would an observer from Earth on the Sun be an Earth obsever?

He could be. But usually he's not, and there is a big
difference between "is" and "could be"

is there a difference between..."usually he's not", "could be" and "is"?
It sounds sooooooo uncertain.

Or do you mean...usually is?
