In fact energy itself is not + or -. Only some manifestations of energy are + or -, like charge. But not heat (if we measure properly: with kelvin), nor sound, nor Kinetic energy (how could motion/space be negative?), nor entropy (how could time be negative?), nor potential energy (how could you have the ability to do less than 0?)..... And mass can also be gained and loosed, we do it when we eat and shit (if someone is scandalized by the word, tell me). |
Don't we say motion s -'ve' relatively all energy is relative to other that is why it is - or + but mass is'nt relative it is the- u see the definition. mass can also be gained or lost bu in different states that is there is energy working inside hding behind the name tag of mass. So when we use we must say energy - or +. not mass.
That's the secret to life... replace one worry with another.
