eli5: if everything in the universe is constantly revolving at insane speeds, why are the constellations and star patterns the same all the time?
In: Physics
Insane distances. The closest star to earth is more than 4 light years away. Most visible stars are hundreds or thousands of light years away. They’d have to be moving at pretty close to lightspeed to move an appreciable distance in human timescales. One of the fastest stars in the galaxy is moving at about 1,200,000m/s.
Lightspeed is about 300,000,000m/s
