OK, I'm going to ask some stuff here that some folks might think ridiculously basic. But I'm gonna ask anyway.
Converting "fuel" to energy -- does the mass of the fuel disappear from the universe? Whether it be rocket fuel converted to thrust, or food converted to body activity.
A rocket has X tons of fuel. When it blasts off, that fuel is converted to thrust energy. Yes? But the exhaust expelled still has the same mass as the original fuel, but is just in a different form. Yes? Instead of being a solid of X tons, it's now a gas of X tons (in a bigger volume). Yes?
We all eat an amount of food, burn some of it as energy for our activity, and "make waste" of some of it. But, (I'm about to make an assumption here), our waste does not equal our food intake. Yes? So the difference in the "intake" and "output" is what was converted to energy for activity. Yes? But if our bodies aren't increasing in weight/mass, that energy . . . "disappeared" the mass we intook?
I understand that the food we eat gets changed down to molecular/elemental levels, but the overall mass of those collected molecules/elements doesn't change, does it?
