Need help understanding how the angular size of distant objects changes depending on the shape (curvature) of 3d space that you're in (related to CMB fluctuations)

If spacetime "isn't a thing", but just defined by the distances between events, how can it be curved?

The Nyquist frequency is supposed to be the highest frequency that can be played at a given sampling rate. But since by necessity it would be in the form of a triangle wave, shouldn't this lead to some overtones higher than that frequency?

How is it possible that comet trails stay in the same location over many years? Shouldn't they either be in orbit or falling into the sun?

Would the average in-shape adult benefit more from 30 minutes of moderate cardio every day, or would it be better if they took a day or two off each week?

Do the events in the brain that lead to physical movement and/or thoughts occur on big enough scales as to not be affected by quantum indeterminism? If so, wouldn't this imply that the brain is effectively deterministic?

I've heard that people today are taller than people were a few hundred years ago. Why is this and is it a form of evolution?

Since accelerating is equivalent to being in a gravitation field, would a clock at the edge of a rotating disk experience gravitational time dilation?
