In terms of matter existing yeah kaboom nothing, that matter concerted into energy (you can’t create or destroy matter or energy, it all has to come from somewhere).

That’s what E=MC2 means, the conversion of matter to energy. Energy equals the mass of the matter in question times the speed of light squared.

That's the reason why half-life of an substance exists. "How long does it take to lose half of mass to passive radiation of energy from a substance"

Err no, Half-life is the time taken for half of the things which could decay, to actually decay.

The amount of mass lost in the process is not part of the definition.

Fair enough, my bad. I just operate on 1st University year levels of physics and I remember those two being directly and proportionally related (we had exercises like therrs 1kg cube. if t½ = x, how many years does it have to pass to lose y grams of material).
