OK, I will accept that information cannot be communicated faster
than the
speed of light. However, even in single particle EPR experiments MWI
requires the creation of two particles for every one particle.
That doubles
the energy requirement. Considering the total number of particles
created
in the huge number of interactions resulting in what MWI calls new
universes, where does all this extra energy come from. Personally
I prefer
to believe in the conservation of energy than MWI.
The conservation of energy is not a law of logic, according to
Noether's
theorem it's just the result of the laws of physics remaining the
same
during different times, and in any universe where physical law is
the same
in different parts of it there must be a law of conservation of
momentum.
The laws of physics remain the same in different regions of
spacetime in
our universe so we have both those conservations laws, but there is
no
reason to think they would remain the same throughout the entire
multiverse, and thus no reason to think those conservation laws are
fundamental.
The Multiverse equivalent of conservation of energy is unitarity of
the evolution of Schroedinger's equation. Or equivalently, that the
Hamiltonian is Hermitian.
I also like to point out that unitarity is also equivalent to
conservation of information, or in other words "if something can
happen, it will happen, somewhere in the Multiverse".
I don't see the relation between conservation of information, and
everything happens in the multiverse. It is more that if something
happens, noone can make the trace of it disappearing.
The null universe with state the null vector conserves information,
but nothing happens to it, even from inside.
Best,
Bruno
