That explains a few things that have happened over the last few years - we got forked in time. ;)

Thanks. Now I am back in the right universe.

If there are infinite multiverses, then there are some interesting considerations:

1. If new multiverses are spawned off every time that a particle can assume more than one state, then it is not a question of whether or not you survive an accident. It becomes billions and billions of questions such as what happens if a particular electron in a particular atom in your shoulder jumps to a different state at the time your car hits the railing.

2. If multiverses are only spawned when an observation is made, then we had a single universe up until the time that the first sentient being was created. Before then there were no observations, unless we consider God an observer. If we are the only sentient beings, then was the first multiverse spawned when the first intelligent ape was formed? the first homo sapien? the first scientist? the first person to observe a quantum mechanical effect?

3. In most parallel universes when scientists perform the two slit experiment they see what we see: an interference pattern caused by a series of photons going in equal amounts through two different slits. However, in countless other universes there are a bunch of scientists who are still confused about why only 40% go through one slit and 60% through the other. And there is at least one universe where all the photons go through one slit or the other. How confused are they? Can they even do science in those universes? And why did we luck out and have a universe where quantum mechanics makes some measure of sense?

4. If every possible universe is possible then there is a being similar to me that goes from being Hitler-esque in one universe to nothing short of Mother Theresa in another. If the laws of physics require this to be so, then morality is a meaningless concept. No matter how good I am in this universe, I will be required to be evil in countless others thus negating any overall moral effect. If free will is superimposed upon quantum randomness, then it might be that if you averaged all the multiverses the average person would be better than expected due to God's influence ... or worse than average due to God allowing Satan to work his "charms" on all of the beings in all of the multiverses.

This is all quite silly.

Think of each possible universe as just another frame on a film.

Turns us into "projections", but that's better than being turned off, eh.

The new work bolsters his claim that quantum theory does not forbid time travel. "It does sidestep it. You go into another universe,"

The double slit Delayed Choice Quantum Eraser is an experiment that has already been done and appears to prove you can change the quantum past without going into another universe.

[Equations deleted].

Sure, but try to find a decent Hamiltonian for H, and then find a good enough basis to express it in...

Let me know when it converges; I won't wait up dinner for you.

Sound of grey_whiskers purring.

Cheers!

"The double slit Delayed Choice Quantum Eraser is an experiment that has already been done and appears to prove you can change the quantum past without going into another universe."

But, it is only a ""proposal

One problem, you can’t change your own parallel universe vis TT. So all you get is an infinity of models. Time wasted!

The experiment's actually already been run.  There's just a question of what the results mean:  it either half-works, or doesn't work, or the expected pattern doesn't manifest when "created in the past"

But something seriously weird is happening.

Since I’m not a scientist, I’ve had to think about this for awhile.

Is it possible that the feeling we get of deja vu isn’t really a “I’ve done this before” but a possible nanosecond aligning of the parellel universes where I (all of me) are doing the exact same thing at the exact same time, and a blending of ‘our’ consciousness?

Possible?

"Possible?"

Infinitely possible!

But, maybe not.
