It can look dumb, but I always had this question as a kid, what physical principles would prevent this?

    Yeah IIRC that even applies to things like gravity as well. As in, we aren’t actually orbiting around where is sun is, we’re orbiting around where it was ~8 minutes ago because the sun is about 8 light-minutes from Earth.

      No, gravity is faster than light. If there was this lag, we wouldn’t have stable orbits exactly because of the lag you describe. Wave functions of photons also collapse faster than light when they hit absorbent material.
