It's good to see you agree that there's no conservation of

law of the conservation of power. Have a good thanksgiving.

Division by a quantity as it approaches zero is not
always undefined, Tom. The limit, as the denominator
approaches zero, is often the first infinity, aleph-null.

The momentum in any volume of space must be conserved.
The joules in the joules/sec must be conserved. Please
don't try to hoodwink the uninitiated into believing
otherwise.
