I forgot that radioactivity existed :o. Granted, all I know about it is that carbon dating is used and that's related. And carbon dating has to do with emitting something. And I guess emitting something means losing mass or energy.

Err, so anything internal is not accounted for because it's all part of the rest mass. And for things like atoms bouncing around, Newton's third law says that within the object, that sort of bouncing will be balanced out by another atom because within the object itself there is an equal and opposite reaction..?


Electron volts! I don't know what a volt is but it's interesting they use energy, and that it's electrons. Why not quarks xD?
