Many Worlds Interpretation

[michel123456]

Someone inserted an interesting post about David Deutsch, and I spent some time reading about quantum computation & the Multiverse.

In some wiki page about the Many Worlds Interpretation, I found this from the "Common objections and misconceptions" list:

 

Objection: Conservation of energy is grossly violated if at every instant near-infinite amounts of new matter are generated to create the new universes.

MWI response: Conservation of energy is not violated since the energy of each branch has to be weighted by its probability, according to the standard formula for the conservation of energy in quantum theory. This results in the total energy of the multiverse being conserved.

from http://en.wikipedia.org/wiki/Many-worlds_interpretation#Common_objections_and_misconceptions

 

Is there anyone here who could explain somehow better this response: This results in the total energy of the multiverse being conserved. ?

The explanation sounds weak, but what do you expect from a guy that subdivides every time he's indecisive?

 

Hopefully he came up with something better in the "Other Worlds".

hm. Yes.

My question came also from the fact that in the article I quoted, the Many Worlds Interpretation is presented as a fairly mainstream theory. See in Reception "Many-worlds"-like interpretations are now considered fairly mainstream within the quantum physics community. For example, a poll of 72 leading physicists conducted by the American researcher David Raub in 1995 and published in the French periodical Sciences et Avenir in January 1998 recorded that nearly 60% thought that the many-worlds interpretation was "true".

The energy emitted by my emitter is entirely absorbed by my absorber so no energy is left to create other universes.

??

My opinion is that in the MWI, conservation of energy is violated.

My question was: why is this opinion a misconception ?
