Actually, standing on the earth we are already moving at over 1,000 mph.
If you point a flashlight in the direction of rotation--it has the
potential of +1,000 mph than when you turn around and point it west.
Nope, that's not true. You will measure no difference. An observer
fixed compared to your position would measure a Doppler frequency
shift but no difference in velocity.
Also, the universe is expanding, and that is pushing us on at a good
clip. Funny you don't see this being taken into account anywhere except
on space launches...
But it is taken into account. Most astronomers don't believe the
red shift is pure Doppler effect.
