comment Thought experiment - would you notice if you fell into a black hole?
Yes, the Sun travels around the Earth. All the observations show this. All the math shows this. There's even a model that show this: <en.wikipedia.org/wiki/Antikythera_mechanism>; Just because everyone agrees, that doesn't make them correct. Light cones never tilt or change shape. They only compress or stretch.

Your diagram is wrong; light cones do not tilt. If they did, the speed of light would changed. Light cones are stretched out, that is, the isolines of constant time intervals move farther apart but the shape does not change and it does not tilt.

comment Double-Slit Experiment Timed
No, that's not it. I don't see anywhere in it where the particle is timed. And I don't see any reference to who did the experiment.
