Thank you! Is it the same energy as referred to in e=mc2?

What about the heat we give off after intense physical activity? (Or the heat we're constantly giving off) Where does it come from? Does it come into us as heat, or does it come in as food/drink? Is this "heat energy" even the same kind of "energy" referred to in e=mc2?

Thank you for replying! In Bill Bryson's A Short History of Nearly Everything (Page 373 of the hardcover edition, Part V "Life Itself", 24 "Cells") he says: "Brain cells last as long as you do. You are issued a hundred billion or so at birth, and that is all you are ever going to get. ...

Greetings! I have read/heard from various sources that none of the cells in my (or any other human's) body now are the same as they were seven (At least one source said nine years) years ago. I remember reading from one source that some cells don't "die" but all of the separate parts are...

Thank you all for replying. I'd really like for you to explain this in more detail, because if someone were to say "reality is not all one" in place of your first two sentences, and dropped the final sentence, it would seem to make even more sense to me. I feel like I'm missing...

Thank you for the replies. That's what I'm talking about, DaveC, but would you be able to explain it a bit more, please? I don't quite understand what the energy in the vacuum is.

Thank you! What about particles that come out of (what seems) nothing and (almost) instantaneously ceasing to exist? How would they have been around in the Big Bang?

Thank you for the welcome. I'm speaking on a level more basic than a human and a stone, I mean in the most fundamental sense, are we all made of the same "stuff"? I've heard in quantum mechanics things can pop in and out of existence almost instantly, would these things be separate...

Greetings, I am wondering if all reality is one happening, or if it can be reasonably believed to be a collection of wholly separate happenings. To express the question another way: Do we ("We" meaning existing beings) grow out from (as grass grows out from Earth) or come in to...
