ChaosRequiem flat Earth people cant dispute red/blue shifts. As you can see "the engineer" has no idea what he is talking about. He says the starts can move relative to us. That would lead to no shifting of the wavelength.
Well, in the RE, the stars are moving relative to us, yet there is shift. I think you don't know what relative means.
The fact that they think the Earth is accelerating upwards also shows this. I would be able to jump out of a plane and hit the ground at 9.8 m/s since I wouldn't accelerate any more then Earth.
I don't know what I am talking about? You do know that there is a difference between velocity and acceleration, right?
Velocity is a vector, thus having a direction, while acceleration is a scaler or something. 9.8m/s/s is an acceleration. It adds 9.8 m/s every second.
How does this acceleration bend light? If everything was moving relative to each other there would be no light bending. But there are many ways for astronomers to see a certain light by aiming a telescope a up a little ways to catch the light that was bent.
