    I mean, that was my first thought… but would there be a measurable difference?

    I mean lets be clear, with a fan you’re adding like 8 mph to something going 299,792,458 meters per second. You won’t notice anything.

    But like, vacuum vs glass vs glass moving half the speed of light, could be an interesting what if. Relativity is always where my mind glosses over in physics.

      Unless the air particles make real contact with the photons then you’re not adding anything to anything, and the ones that do will be deflected.

      Imagine a rock in space coming close to hitting a planet, or even entering a solar system at all. Similar scale.
