    Not inherently stupid question; they just don’t know that radio waves don’t travel through air but through space.

      does this mean radio waves can go to mars? if so, why don’t we ride them to mars?

      It’s not much of a stupid question even given that - for a refractive medium, speed of light can change with its movement. Though for air it’ll be extremely hard to directly notice; it has n≈1.0003 so speed of light in air is already 0.9997c, and increasing it to, say, 0.9998c would require moving the air at 0.166c.
