I have been an adult for so, so long and still get squeaky delighted by bubbles coming out of the dish soap bottle unexpectedly, and my daughter's girlfriend got me hello kitty jellybeans, some things don't get old and I don't know why - expected to be jaded way before now and I just am not.
And some things are just fundamentally amazing, planted watermelons and they just set fruit and those vines grow so far every day, how do they do this just by eating sunlight? Every time I go look at them I am astonished.
Interestingly the watermelon (and other plants) don't quite eat the sunlight, but the chlorophyll in the plant uses the sunlight to get enough energy to steal the carbon atoms from the CO2 in the air. So your water melon is literally made out of thin air!
Well the nutrients come out of the soil, but yes it’s all “powered” by sunlight
When you lose weight, it is literally breathed away out of your body into the air
Is that true, though? Your body needs energy for various tasks and those have different mechanisms of spending the energy. Muscles, for example, move, which creates heat. But that heat is not simply breathed out.
The heat is literally produced by oxidizing (burning) carbon that you then breathe out as carbondioxide.
Producing heat isn't where the mass goes though - mass is conserved. You only lose mass to energy in a nuclear reaction.
Something has to go in there, if not losing energy to radiant heat transfer, then how e=m(c^2)?
I'm not sure what you mean by in there but yes, the heat would be transferred to the environment.
E=m(c^2) describes how much energy is contained in matter. It's useful for nuclear reactions, but your body isn't a nuclear reactor and you aren't consuming substantial quantities of radioactive isotopes, like uranium ore, that will decay on their own so it isn't relevant here.
Still energy is being radiated. A mass loss has to occur for that
