Can energy and matter dissapear?

[Glenn]

"Two years ago, I told you about a paper by Subir Sarkar and his colleagues, that showed if one analyses the supernovae data correctly, without assuming that the cosmological principle holds on too short distances, then the evidence for dark energy disappears. That paper has been almost entirely ignored by other scientists. "

How about cold dark matter?

Do we really live in a hole in the Universe?

They can disappear. But they cannot cease to exist. They can
change form into something we can't perceive, but they're still
there.

Sorry, but I'd rather get misinformation and speculation from evolutionists.

Oh you'll get plenty of that.

I have no concrete idea of "dark energy", but I think
that a lot of paper is of poor quality even after passing
valid "peer review", and in particular because of deliberate
fraud historically poorly detected at that point. And a
paper may be ignored by "other scientists" for very good
reason, that they honestly and fairly disbelieve it.

And we know, of course, that the "Uncommon Descent"
web site was created and is operated with the purpose
of committing scientific fraud in support of a religious
doctrine that was discredited before you were born -
without considering "dark energy".

Can energy and matter disappear?
----
1 - There are many examples when energy and matter disappear (becomes infinite) .
For example: the collapse of the Schrodinger psi- ψ-wavefunction.
2 - There is law:
"The law of conservation and transformation of energy/mass"
and this law (seems) must forbid psi- ψ disappearance.
3 - But if this happens, then solution can be one:
the law of quantum "transformation" comes into force.
4 - Quantum physics know only one such law: Lorentz transformations
======..

[Ernest Major]

I'm having difficulty reconciling my knowledge of physics with what you
write.

1) Becoming infinite is not the same as disappearing. The better known
infinities in physics are classical (relativistic) - the Big Bang and
black holes as treated by General Relativity. Though in the absence of
renormalisation quantum theory also has singularities - such as the
infinite self-energy of a bare electron, arising from it being modelled
as a point particle.

But wavefunction collapse is involves neither disappearance nor
infinities. Wavefunction collapse (not that everyone likes the
Copenhagen interpretation) is that when a measurement is applied to a
state which is a mixture of eigenfunctions of the wave function, the
result is a state which is a single eigenfunction, and the future
evolution of the system is from that state. Wave function collapse
doesn't change the energy (including mass) of the system.

2) Therefore the law of conservation of mass/energy does not forbid wave
function collapse.

3) I don't even know where to start to interpret this.

4) The Lorentz transformation is classical (see Special Relativity) in
origin, but is also used in relativistic quantum mechanics. I don't
understand why you think that the Lorentz transformation is the only one
used in quantum mechanics.

If QM must be limited to a single law, ISTM it would be the
Schrodinger Equation.

Pedantically, my understanding is physicists treat electrons as a
point only as a convenient simplification. If an electron's size has
any meaning, it would be its Compton wavelength of
2.42631023867(73)×10-12 m. I acknowledge this is very small, but not
infinitely small.
