MWI and time

[Eva]

Hello guys :) what do you think about time in many world interpretation?
If there is one changless global wave function, than why we have change at all?

All these states, different branches which emerge or are incribed in global wave, are not changless - we experience change.

Why?

Is it because they are relative?

If so, everything which is relative is transitory?

In MWI there is the global wave function, and with respect to any observer's measurement outcome this is manifested by a projector that reduces observed state of the quantum system. The time any observer records on their clock would then be the same as the global time. Things only get a bit odd when we consider different eigen-branching of the system are in different regions of gravity so they have different proper times.

Hi Eva,

The founder of this list published an interpretation of QM that embodies both timelessness and many worlds.

He calls it: "a really simple interpretation of quantum mechanics":

So I think you are right it isn't needed in any objective sense. As far as why we experience it, I think the reason is thermodynamics. It takes energy to process and record information (Landauer's Limit) and since energy can only be expended in one direction of time, information processing systems like life and brains evolved to process and record information as soon as it was able to (moving through the present from the past, and into the future). But this feeling is a subjective illusion.

Thank you! I have to admit that I like this interpretation. Some people say that it even explain cosmological fine-tunning
