Now. As I understand it, in fact, the earth (10^25 kg) creates a very small, very tiny, frame dragging effect. Indeed, we have measured this using satellite experiments.
So, the Earth (10^25 kg) creates a very tiny, minuscule, frame dragging effect.
I ask -- is there anything big enough, that it creates a let's say "non-tiny" frame dragging effect?
So for example, you astronomers who work with (say) super-clusters of galaxies, do you have to, as a matter of course, figure "frame dragging" when doing calculations regarding the size/shape/etc of these mega-objects?
Finally, I've tried to read what I can about the frame dragging effect of black holes - but I find it confusing and sort of not applicable to what I'm asking here.
Again to recap what I'm asking:
So, I know the Earth has a (tiny, minuscule) frame-dragging effect.
What about a star like the sun? A galaxy? A super-cluster?
How big does an object have to be to have "non-tiny" frame dragging effects?
Are frame-dragging effects an every day calculation for those who deal with (say) galaxies? clusters?
Thanks! I hope this is clear.
Note! here are some actual answers, thank to the amazing J.R.:
The sun and Jupiter - both still have extremely tiny frame dragging effects (about 100 times bigger than the Earth's extremely tiny frame dragging effect).
Galaxies - in fact - and I couldn't find this answer anywhere on the internet - galaxies in fact have trivial / basically zero frame dragging effect. (Since they are so thin.) Astounding!
Note! I previously included the following prelude to this question: If you spin a bucket of water, of course, the water "forms a concave shape" - Newton's Bucket thought experiment. As I understand it, physicists now believe that if you spin an astronomically large bucket of water then in fact very surprisingly ... it does not make the concave shape ... due to "frame dragging" cancelling the inertial force. However, it now appears I was totally confused on this issue, so I have deletd the prelude to avoid confusion. Sorry. (It's very much worth noting that all the discussion you can google up about "newton's bucket + frame dragging" -- seems very confused, so research with care on this topic!)
