alexander:

and thats your fault, go pick up a physics book, by any recent known scientist, read it, get over the fact that you are wrong, and start answering questions

I think I'm right and that those Physics' books are wrong, I'm sorry.

By the way its transverse not "transversal" mass.

Right, time passed since I last talked about and I forget that but it means the same isn't it?

Lets start with basics, how do YOU define mass?

Mass is a mathematical parameter (a number) characteristic of the elementary particles of the Universe present in several important laws of Physics like F=ma, gravitational field, E=mc2.

Something similar is the charge, just a numerical parameter characteristic of the particles.

More complex bodies are constituted by many particles and the total parameters mass and charge are the sum of those of their particles.

Charge is a constant for the elementary particles but their mass can vary in some circunstances. In the new theories is directly related to the current of the rings that compose the elementary particles. Yes the new theory give structures for the basic particles of nature like the photon. If you are interested you should read more in the manuscript (begining in Section 3.1), is not easy to explain the complete characteristic and features of the elementary particles proposed although the basic structure is simple.

at this point direction matters... are you talking about symmetric acceleration in opposite directions?

works the same way it does with one twin accelerating away from the other, within the initial frame of reference, the twins would both age at the same rate...

That from the point of view of the "stationary" frame because each twin see a different thing and here is the inconsistency.

Note that is not a matter to decide which point of view would be right and which would be wrong, the problem is that in different frame of observation we obtain contradictory results and that means inconsistency. A right Physics' theory cannot be inconsistent. Any phenomenon must have totally compatible observations in any frame of observation. The reality is only one. As I say in the section photographs can be taken and be sent to everybody, even us" to see what really happens.
