Thanks for the in-depth explanation.

The way I see it, MWI is more of a philosophical idea. As far as I know, it’s impossible to test it, so currently it’s still firmly outside the sphere of science.

You pointed out some valid reasons why the future of MWI looks shaky, and I’m fine with that. If MWI falls apart, I’ll just move on to the next best thing. I just find MWI intuitively appealing, but I don’t have any strong reasons to believe it or reject it. As you mentioned, MWI doesn’t change the way you would carry out quantum mechanics, so currently it has no practical impact.

Bring some ice cream too. Those kids will never be the same after that.

Exactly! That’s the sort of time travel I’m talking about!

Next stop: 1095, the office of Alexios I Komnenos. Who wants to see what the world looks like without the crusades?

I’ll visit past me and leave some letters that contain useful information. You know, don’t trust those people, avoid doing this mistake, know yourself etc. would be interesting to see how that timeline diverges from my own.

Actually. now that I’ve opened this door, might as well try influencing world history on a larger scale. How about I visit certain key moments where a dangerous person almost died, but survived to cause massive harm later down the line. Would be really interesting to see how history plays out after nudging Hitler a little bit closer than to that suitcase. History is just full of special moments like that.

I wouldn’t be a passive observer. I would actively change things to see what happens.

BTW, I believe in the many words interpretation of quantum physics, so all possibilities are equally real and they all exist simultaneously. No matter how hard you try to fix things or how badly you mess things up, that disaster branch was already there, always will be.

Try that with cheap mobile phone charges. They have an annoying coil whine.
