That is a very thought provoking thought experiment.Fletcher wrote:1 in 4 you say. That is impressive. Sun goes around the earth !
Can't think of an actual experiment atm. But I can think of a thought experiment.
I take off in my space ship . . .
I watch it intensely for 24 earth hours and earth 'appears' to rotate one whole turn about its axis. Pluto and the Sun stay in their relative position to me. I notice that the astronomical background of stars relative positioning to me has effectively not altered at all in this 24 hour period.
I conclude that the earth is stationary in space, not revolving, or moving in any way. It is me and my Solar System, and all the other galaxies I can see that is turning around earth ! Which it does in 24 earth hours !
Go figure ! 1 in 4 you say !

How is it knowable what is moving? That is the question. Vection sure can be vexing.
Since all the things I see are projected upside down on my retinas, I'm just glad I don't
have to stand on my head to see things as they should be.
It also is a bit annoying to have to wait on the light to bounce off of things on the way to my
retinas. Why should I have to wait to see things and then never really get to see them? All
I get to see is the light!
One last thing. Next time you go to Pluto, I have a passenger for you.
