ABOUT Istvan's posting:
consider the following thought experience:
subject moving inside a ship at 0.99 c from earth to alpha-centauri;
when arriving to alpha-centauri then
subject jumps instantaneously from that ship
to another ship in the opposite direction
moving at 0.99 c from alpha-centauri towards earth.
the instantaneous character of the jump (infinite instantaneous acceleration
at alpha-centaury) leeds to results on the twin paradox (within special
relativity) coinciding to those given by general relativity (with finite
negative / positive accelaration near destination).
my thought experience is not physical! but it is mathematicall.
can you carry out this calculation on the Twins inside your system?
