For the other readers: So here is a PhD who is given direct answers from even the experts who helped formulate the laws of thermodynamics and he can't grasp what he is being told. Good grief.
Put another way, here's a creationist who's being told
by one of the experts he claims to be following that he's misunderstanding the physics, and he won't consider for even a second that he's wrong.
1. He objected originally to what I said about the fact that the 1st law of Thermodynamics would not allow a natural origin for matter. Why has he changed the context of that statement to begin with?
I objected to this statement: "Stellar evolution violates the 1st Law of Thermodynamics. 'Matter can neither be created nor destroyed' (wikipedia) by any natural process." I then challenged you to support your claim that stellar evolution violates the 1st Law. I am still waiting for you to do so. (You do know that stellar evolution has nothing to do with the Big Bang, don't you?) I also pointed out that your statement of the 1st Law was wrong, since it is.
2. He objected to what I said about BOTH the 1st law (Matter/mass cannot be created nor destroyed) AND the 2nd law (in part: defined as the measure of disorder).
The 1st law prevents nature from creating matter and the 2nd law causes all things to become disordered....and THAT flies directly in the face of his so-called stellar evolution belief.
He says,
"Just leave "matter" out of it, since by the most common physicists' definition of "matter", we can create matter."
Why? Einstein didn't. He said matter and energy were interchangeable, but he wants us to believe HIM instead of Einstein and those who agreed with him. But no matter how many times I have quoted the leading experts in this field on the matter he doesn't get it.
I said that physicists can create matter, because they can and do, using the most common meaning of "matter" that physicists use (which Einstein of course knew perfectly well).
Look up "matter creation" in Wikipedia, and you'll find a whole article on the subject. It begins, "Matter creation is the process inverse to particle annihilation. It is the conversion of massless particles into one or more massive particles," and goes on to note, "in high-energy particle colliders, matter creation events have yielded a wide variety of exotic heavy particles precipitating out of colliding photon jets."
In other words, matter (as the word is usually understood by physicists) is routinely created in particle accelerators -- which means it really can't be impossible, can it? (I was an experimental particle physicist for ten years, so this is not exactly new to me.)
Quote: "The
law of conservation of mass, also known as the
principle of mass/matter conservation, states that the
mass of an isolated system (closed to all matter and energy) will remain constant over time. This principle is equivalent to the conservation of energy, in the sense when energy or mass is enclosed in a system and none is allowed in or out, its quantity cannot otherwise change."
Continuing to read in the
same Wikipedia article, we come to the section "Exceptions", which states, "The principle of
matter conservation may be considered as an approximate physical law that is true only in the classical sense, without consideration of special relativity and quantum mechanics. Another difficulty with the idea of conservation of 'matter' is that 'matter' is not a well-defined word scientifically, and when particles that are considered to be "matter" (such as electrons and positrons) are annihilated to make photons (which are often
not considered matter) then conservation of matter does not take place, even in isolated systems."
Conservation of energy is, as far as we know, always true. Conservation of matter is not. So equating conservation of energy with conservation of matter is
wrong, which you would know if you read and understood the very article you're quoting.
Stellar evolution conserves energy, and therefore obeys the 1st Law. Whether it conserves "matter" or not is irrelevant, since the 1st Law isn't stated in terms of matter. Now, if you wish to define matter as being identical to mass (and therefore energy), then matter is indeed conserved -- but in that case stellar evolution conserves matter, too.
So I'll ask yet again: please show how stellar evolution violates the 1st Law.
