The H-Bombs are slowed by parachutes so the bomber can get away. The outside temperature for a B-52 at operating altitude over Russia would likely be at least minus 60 degrees F. Major T, since he was wearing an indoor uniform, would become a solid block of ice before the bomb went off so his TOD has a variance of time between when became a solid chunk of ice and the time of instant defrosting. This could be 30 to 60 seconds. Totally un-acceptable accuracy for even the cadet grade newbe time-nut ;) Why, anyone accepting such an error would have to answer to the Coca Cola company distributor at Burpelson Air Force Base.

Surely astronomical events are rather rubbery. The distance between the celestial bodies is measured in Light Years, this must give uncertainties as the exact distances are varying all the time and the solution of the many bodied problem is probably chaotic, meaning that it may not be possible to deduce exactly where anything was at some point in the past. The rate at which time happens depends on the local gravity and that varies as everything moves around. What we need here is a Grand Unified Time to keep cell phones working through the universe. How would you administer that to a nanosecond? I am sure Douglas Adams would have had some humorous situations with excellent moral messages for us if he were still here. cheers, Neville Michie On 29/10/2010, at 5:18 AM, Marshall Eubanks wrote: > > On Oct 28, 2010, at 2:05 PM, Max Robinson wrote: > >> How about the crab supernova. >> > > Msec pulsars are much more stable - see http://arxiv.org/pdf/ > 0911.5534 for some comparisons. > > Regards > Marshall > >> Regards. >> >> Max.

Neville, The Time of Arrival error for the millisecond pulsar J0437-4715 is about 11 nsec. This takes into account the location of the pulsar, the solar system's barycentre, the earth's (perturbed) orbit around that barycentre and not to mention the interstellar medium that the pulse has to travel through and be dispersed by - all to an accuracy of about 3m. Not bad and certainly not rubbery!

How about some alignment of the planets that has occurred in the lifetime of the Earth but only happens infrequently on a celestial timescale.
