This doesn't make sense

Velocity does not add linearly.  It appears to do so when speeds are very slow compared to c.  The actual formula for adding velocity is:

w = (u+v)/(1+uv/c^2)

You stated that earlier, and it doesn't really help.  Do you have anything else, or a different way of putting your statement?

Is there any way to put it into terms that don't involve equations, for those of us to whom they mean nothing?

What happens as the earth approaches the speed of light that prevents it from ever getting there?

Velocity does not add linearly.  I will give you an example:

A spaceship is traveling at .6c, and a person on the ship fires a proton gun, which shoots the proton at .8c in the direction of travel.  In classical mechanics, you would say that v1+v2 = v3, or .6c + .8c =1.4c!  But that is impossible, as nothing can travel faster than c. 

Using the equation I provided:

w= (.6c+.8c)/(1+(.6c)(.8c)/c^2)) = .946c

Moobs, that equation assumes that time is a constant.  Einstien proved this wrong.  Your formula is only applicable at low speeds.  The speeds that the planet is traveling the time dialiation must be taken into account.

What are you talking about?

I was refering to what equation he had provided.  I know how time dilation works.

Well his equation, as you already pointed out, is incorrect as it creates results that surpass C.  Your equation already accounts for the time dialation of einstiens relativity and its affect on the moving object to an observer.

Equivalence theory proves the Earth is Round because a sphere with gravity would feel the same as an eccelerating disk so it must be a sphere.

No, we're talking about 2 sides of a coin that exist only in drunken stupors.
