I'm a logical person. Thought myself well-grounded, agnostic after leaving Mormonism...etc... then last year I went down a rabbit hole on some Mandela effects, esp. ones that flip/flop.

Short of it is - the Movie Apollo 13...

I remembered it has "Houston we have a problem!" with frantic Tom Hanks.
I was reading how it's the most misquoted movie line, and is actually "Houston we've had", and that a lot of people have seen this flip back and forth between the two states.

Well, I double checked on youtube and sure enough... Houston We've HAD a problem was the correct/current iteration. Tom Hanks was also a bit more 'cool' like I'd imagine the real astronauts were...

My wife watched it with me and can verify.

Fast forward just 3 days. I'm reading a list of Mandela Effects still intrigued by things like the Cornucopia in Fruit of the Loom never existing...

On this list: Apollo 13 Movie, previous: Houston We've Had a problem, current: Houston we HAVE a problem.

Well, I immediately thought it was a typo. Till I opened youtube. It's now a more frantic Tom Hanks + Houston we HAVE a problem and different camera angles, etc.

Oddly, just about all the links out there claiming it's the most 'misquoted movieline' are still there on many different sites from Buzzfeed to Ebaumsworld. Yet, that ONLY works if the ACTUAL line is Houston We've Had a Problem, because as you can probably attest -- in all of pop culture when that line is uttered it is almost 100% "Houston We have a Problem".

In fact when I first saw the We've Had version, I chalked it up to bad memory because ...well it's just such an ubiquitous line and is used everywhere, in countless movies/tv-shows etc...

My wife can attest - she witnessed the flip too.

For like 3 months after that, I kinda went down some weird rabbit holes trying to find some control of the 'matrix' or simulation...before coming back down to earth. It rocked my world view.

Personally, I think we're either a simulation or that the entire universe is conscious and what we think we're experiencing is a dream of sorts or something, the only way I'd buy multiverse is maybe if the multiverse is reaching some sort of entropy so worlds are 'popping' like bubbles and colliding so that people from different timelines end up together and dispute reality.

If it's a simulation though, I was thinking this same thought that - everything we perceive or believe is a result of consensus, but I don't even think it's total human consensus -as much as it is potential network consensus... if 51% of the people you're likely to connect/network with online or off believe that it's Houston We've Had a Problem, that's what you'll see... say there's a deadly pandemic and people are dropping like flies, maybe those networks change faster... and thus things flip flop back and forth more...

The biggest Mandela Effects seem to be related to popular content, so it's usually things where there easily has the majority of people who at least have a memory of something one way or another. For instance there's lots of biblical MEs like there used to be a scripture about the lion laying down w/ the lamb, but it never happened. There's also many spots in the bible where it feels like the word 'things' should be 'possessions' and 'alien' should be 'stranger'... and I don't even believe in the bible, some would say it's 'Satan', but what's he have against Apollo 13 or the Fruit of the Loom Cornucopia? or "Objects in Mirror MAY Appear closer than they appear" (may be is actually 'Can').

I think it could also be related to quantum physics double eraser / delayed choice experiments, but I'm not convinced that quantum physics doesn't actually lead us to discovering we're simulations. To be honest there's some trippy concepts/theories and actual experiments in that area.
