So you can claim what the Lorentz transform predicts for
the twin paradox, but can you apply the Lorentz transform to prove
that you are right?

Consider the following thought experiment:
Given an inertial frame K with coordinates [t, x]. (y = z = 0)
Twin A stays stationary at x = 0 in K, while twin B starts from
x = 0 when A’s clock shows 0 and travels at the constant speed v
to x = L, where she turns abruptly around with a brief, very high 
acceleration for a very short time, and thereafter travels back
to x = 0 at the constant speed v.
She is back at the time T as measured in K.
Since twin A is stationary in K, her proper time when twin B is
back will be τA = T.

If K'[t',x'] is moving along the positive x axis of K[]
The Lorentz transform is:
  t' = γ(t - (v/c²)x)
  x' = γ(x - vt)
inverse:
  t = γ(t' + (v/c²)x')
  x = γ(x' + vt')

γ = √(1 − v²/c²)


The challenge is:
Show what the LT predicts the proper time of B
is perceived to be τB = T.

You are free to use as many frames of reference you might wish.

Of course I know that you are unable to meet the challenge.
You won't even try.

It is much easier to claim that SR is inconsistent,
than it is to prove it.

Isn't it? :-D
