Einstein's second postulate is clearly wrong.
Here is another typical 'cepheid' brightness curve, easily matched with a BaTh
simulation.
The apparent brightness variation is caused by changes in the emitted light's
speed towards Earth as the star orbits it barycentre with a large planet.
Just about ALL 'cepheid' curves can be explained in this way. 'Cepheids' are
not pulsating stars at all. When are astronomers going to wake up and stop
making complete fools of themselves.
