For some years now I have from time to time kept up with developments at
the LIGO sites. Just checked again and saw that "Gravitational waves"
should be being detected by 2005.
Well it is now 2007, and I ain't heard nuthin!
Since 1989 I have had a bet with some of my old colleagues at Auckland
university that these waves (if they exist at all) will not be
detectable by such a system.

Indeed we are apparently looking for a "wave" whose velocity of
propagation is not known at all, and whose characteristics may involve
extra dimensions of Space or even other potential universes.

NASA Achieves Breakthrough In Black Hole Simulation

"According to Einstein's math, when two massive black holes merge,
all of space jiggles like a bowl of Jell-O as gravitational waves
race out from the collision at light speed.

Previous simulations had been plagued by computer crashes.
The necessary equations, based on Einstein's theory of
general relativity, were far too complex. But scientists
at NASA's Goddard Space Flight Center in Greenbelt, Md.,
have found a method to translate Einstein's math in a way
that computers can understand."

I'd like to see what their new math looks like.



I would just love to be proved wrong: as it would at least mean that
physics was on the right track, but I don't think that I will.
Note to LIGO produce fully backed up measurements of a gravitational
wave, like a coincidence with a GRB, and I'll donate $50 from a retired
electronics engineer.
BTW it has happened before look up "Nancy radiation" in the very early
20th century some time.
It may not be much. But at least I'm putting some money where my mouth is!!!
