Tying back to pervect, the way this is often discussed is in terms of who has to accelerate to determine the outcome. Forces change frames of reference in unexpected ways.
The question is whether Superman can have his palm on one side of the ball, say the side from which it is moving away...

Archibald Wheeler has some cool computations about what various things would look like when moving at very high speeds because of the way light travels, in addition to the relativistic effects. There is also a film based on this of what someone would see flying...
That "limited sense" is all that matters to me. At any given scale, I can say the acceleration of gravity is caused by time dilation, but overall I don't get to. Since we cannot actually experimentally test 'overall', that is OK with me.
The curvature of space is an entirely within-theory...
You could think of it as the force that results from the fact that when matter aggregates densely, time slows down.
We usually derive time dilation from gravity, but I think it is just as reasonable to say that the dilation itself causes the gravity. If time is moving slower at one end of a...
Pretty obviously *no one* conceived of the resistance of space to being bent until after someone had thought of space being bent. But any such thing would have *looked just like* the density of aether, the measuring of which is what the ultimate end-game of the Michelson-Morley programme was...
You are talking about one of the theories driving observations as though it were part of the theory itself.
This very lack of resistance (the whole Michelson and Morely thing) is among the initial facts that were taken as proof that it is in fact space itself and not some wave-bearing medium...
You mention Feynman, and I think he may be the only person who does not characterize this as having the electron split and interfere with itself.
Instead, he prefers the approach where you combine all possible timelines and let them interact. So it is more like the electron is free to go...
