Hi, Bruno,
do you have a short (reasonbly WORDED???) explanation for what you
call ENERGY?
I asked this question from several physicists and did not get an
answer I could even follow (not: understand, of course). Math
summersaults do not help.
What about the wiki definition:
"In physics, energy is a property of objects, transferable among them
via fundamental interactions, which can be converted in form but not
created or destroyed. The joule is the SI unit of energy, based on the
amount transferred to an object by the mechanical work of moving it 1
metre against a force of 1 newton."
This is enough to understand my point to Richard: you can't add the
energy between branch of a quantum superposition, because this would
require interaction, where we have only interference.

Bruno,
You seem to be arguing that the total energy in the multiverse is a
constant.
Is that so?
I think indeed, assuming QM (without collapse), that the total
energy of the multiverse is constant, and even equal to zero. Cf
DeWitt-Wheeler equation: H = 0.
Have you read Wilczek short paper referred to by Bruce Kellett?
http://frankwilczek.com/2013/multiverseEnergy01.pdf
It explains why QM implies, at least formally, why we should not add
the energy of the different terms in the superposition.
That seems obvious to me. We never consider that a particle going
through two slits needs the doubling of its energy. If that was the
case, a quantum computer solving big factorization by using Shor
algorithm would need more energy than the one available in the
observable universe.

What I want to know is if anyone takes conservation of energy
seriously?
Yes. Quantum mechanics without collapse does not violate the
conservation of energy. You just cannot sum up the energy in the
different branch of the superposition. If you do, just the two
slits experiment would violate energy conservation, but the math
shows otherwise.
Similarly thanks to the quantization modal principle which is a
theorem in the material modalities (hypostases) we have good
reason that the physics extracted from comp will conserve energy,
and the probabilities.
Please explain how you cannot sum all the energies in each branch.
Because QM's equation allows only interference between the branch,
not physical interaction. You can formally add the energy of
course, but that sum of energy is not available in any branches.
According to Weinberg, that would be the case if the SWE was
slightly delinearize. Strict linearity avoids all physical or
observable mixture of the components of the universal wave, making
such a sum of energy in different branches of the wave non
physical. An hydrogen atom with an electron in a superposed state
of two level of energy has not an energy being the sum of the two
energies. You don't need that sum of energy to put the electron is
such a state. the superposition of the incoming photon will be
enough.
I might think of a more formal treatment of this.

I suspect that Bruno is differentiating physical existence from

What's the difference? Isn't physical existence the
paradigmatic case? the example we point to when asked to define
"exits"?
Not wanting to bypass Bruno's more sophisticated explanations, I
tend to equate "physical existence" with the idea of something
existing independently of an observer. Or, to put it another
way, taking 3p reality seriously. No?
Sure. Does anyone not take it seriously - I mean anyone outside
a mental hospital?
