heres is a paper [1] from 1994 here the results of weighing thermodynamically closed reactions are "interpreted to reveal the existence of a heretofore unknown kind of non-bradyonic, cold dark matter with two different forms of interaction with normal matter"
Maybe the muons are hitting the angels at a good fractions of the speed of light and the difference is the angel-splat. Maybe FERMI can contract Dr Klaus to come up the an experiment to measure the angel-goo and true the difference right up. Thanks for the link to an 'authoritative source'. :-)
Absolutely. there's this Paper from 1999[1] "Experimental Evidence of a New Type of Quantized Matter with Quanta as Integer Multiples of the Planck Mass" about how the weight of a closed system with a chemical reaction changes, violating the conservation of mass.
"Weightable soul". Sounds like a con-man, who wants only the most foolish of marks to make his job as easy as possible, and hence begins his script "I am about to hoax you...but I have something very important to tell you" - and those that remain after that are proven suckers and can be taken to any sort of ride.
- still looking for a better link than the Book… I’ll update this later
