luminosity, top right.

But now this is moving at some velocity.

Well, once again, if we assume that this train is stationary, and that's, I guess, the key assumption we have to make.

So now we can plot this normalized quantity.

look like train A is going?

The central surface brightness versus

If the velocity of B was 0, if this green train was really stationary, then we'd be moving relative to this train with velocity A.

At 600 meters, represents about 1 mil dot 21 inches.

Which looks a little bit like Tally Fisher or Faber Jackson relation.

So relative, if we assume, because when you take a velocity, you can always take a velocity relative to something else.

The foremost of those were so called Hubble Diagram.

Velocities are 0 and 20 for the decrements of 2.

So our relative velocity to this train is going to be something lower.

I'll specify that by v I want to be clear. This is not vector quantity.

So if you think about it, the back of the column is going to be approaching the rider with the velocity of 4v.

Accelerate to attack speed.

If we subtract 400 from both sides, we get 12 times

Divide both sides of this equation by 12.
