Many idiocies are discussed on this site of John Baez's but the most
important fact: that in a gravitational field photons are accelerated
and their speed can become greater than c=300000km/s - is not even
mentioned. This variation of the the speed of light with the
gravitationsl potential also implies that, after leaving the
gravitational field of the source, photons continue their movement
with a speed lower than c=300000km/s and the potential difference
between the point of emission and the point of reception is one of the
reasons why we measure cosmological redshift here on earth.
