Fortunately there's no false vacuum left to perturb. :-) Anyway, compared to the Sun's output of 3.82*10**26W that's still quite large. > 10 billion is 10**10, PLEASE don't do that in a FAQ. The definitions of bilion, biljard etc. differ wether one uses imperial or SI units, and thuis makes it very confusing. For me, a bilion is 10**12. It wouldn't be the first estimate that was off by some factors 10**6 due to mixing these up. Better to avoid those terms completely. -- ir. J.C.A.
