Thanks Al. Interesting stuff.
From wikipedia, on millisecond pulsars..."Owing to their extraordinarily rapid and stable rotation, MSPs can be used by astronomers as clocks rivaling the stability of the best atomic clocks on Earth. Factors affecting the arrival time of pulses at the Earth by more than a few hundred nanoseconds can be easily detected and used to make precise measurements."
Physicists must have a lot of confidence in the theoretical basis for the existence of gravitational waves to warrant all the time and effort going into their detection. Let's hope they find some of these elusive gravitational waves.
Regards, Rob.
