My understanding is that in the case of an extremely massive object, frame dragging leads to local changes in spacetime that amount to "changing" what the "background" reference frame looks like? If the bucket were…
I like this explanation. I've found that frame dragging (https://en.wikipedia.org/wiki/Frame-dragging) completes this intuition. In a hypothetical reference frame where the universe is rotating around the bucket, the…
The latter (https://en.wikipedia.org/wiki/Quasiparticle)
They examine a quasiparticle, so its "mass" is a number describing the behavior of an emergent excitation of the semiconductor. It's not actually mass in the sense of an elementary particle.
