- This is absurd.
-
- Why, pray tell, did you have to resurrect some obscure reference
- of Bondi's to make this less-than-interesting point? Yes, rest mass
- is not conserved. Yes, 'relativistic mass' (usually read 'energy')
- is conserved.
-
- I hardly think Scott is now rushing to publish this stunning revelation.
