Hello ObsessiveMathsFreak
Their point about the unnessesary use of a second frame in special relativity is interesting though.
Has anyone ever heard of this before. [/B]
This is the starting point in this theory.
If we supress the second frame we get the simplified equations
x' = gamma(vt)
and
t' = gamma(t)
[gamma = 1/(1 - v^2/c^2)^1/2]
as if the two frames where in the same point at t = 0.
So when we derive the expresions to obtain the speed, it yields v' = v.
There is no mixing Vx and V as in the SR equations.
Then we can obtain the force expression as follow:
Fx = gamma^-1 (m0 ax), where mo is the rest mass and ax is the acceleration.
They claim that mass decreases as velocity increases. They say, "Mass decreases as it is used to move an object forward"
If we obtain the kinetic energy expresion we have:
Ec = m0 c^2 [1 - gamma^-1]
This means that if there is no external energy, the kinetic energy must be supplied by the particle mass. A decay process.
But, this is only half of the process, when a photon interacts with a particle there's an absortion process and a decay procces. In the absortion process the energy is external to the particle, so we have:
m0 c^2 + Ec
then
Ec = (m0 c^2 + Ec) [1 - gamma^-1]
and simplifying
Ec = m0 c^2 (gamma - 1) the SR expression
So SR energy equation describes an absortion procces where the particle increasses its mass from the photon energy and the AD equation describes a decay process where the particle's mass decreases and the particle increases its speed.
Therefore, we have the mechanism that explains why particles move.
The explanations in the autodynamic's web are a bit short but they have a book that makes it better.
I hope they will put someday all the book information in the web.
Hope be usefull.
