According to the latest theories, time may be slowing down.   By
acccepting that the speed of light has been continuously reducing from
the point at which the universe was formed, they've worked out that the
uncertainty as to whether the Universe is continuously expanding, or
going to collapse again in a Big Crunch goes away.   Apparently, the
Hubble Space Telescope is just beginning to show some evidence for this
theory of a reducing value for c.

So, in about 4000 000 000 years 137kHz may have become 73kHz.  Or
Topband, or 10GHz, who knows.  Not sure what the implication of a
variable value for c really means.   Antennas will have to change in
length - or will they, perhaps wavelength will stay constant and
frequency change.  Will my Caesium standard still be accurate ?

Its all very worrying :-(
