In what way is it not good enough? The neutrinos are apparently arriving about 60 nanoseconds early, the distance is known, through GPS to 10's of centimeters, and the time is synchronized, again through GPS (although a second method is used as a double check) to about 1 nanosecond. In what fashion is it 'not good enough'? _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
