Speed of Light from Star Moving Towards Earth | Physics with Professor Matt Anderson | M29-02
If a star is moving towards Earth at a speed of 90% the speed of light, what is the speed of its emitted light that we observe on Earth?

Fascinating that it works that way -- the speed of light in different reference frames, that is.
Q: Light has a constant speed in vacuum of space, and a different constant speed in water, etc? So a light coming from a car standing still is same speed as light from a car that is moving, because also in the atmosphere lightspeed is a constant?

Light speed is a constant not just in the atmosphere, but in vacuum. Cheers, Dr. A

Some mediums can make the speed of light FASTER within the medium . They never talk about this phenomenon ...so speed of light is NOT constant. Eiensteins theory is wrong

What is the proof that light is an emission traveling from point A to point b
