In that alternate reality, we exist without the memories of the world we lived in prior, except for some details that don’t seem right.
Moli noted that if the theory of quantum immortality - which suggests that people never really die - is accurate, then humanity might have been ended many times by apocalyptic events similar to the asteroids “taking out the dinosaurs” 65 million years ago.
We would essentially have no recollection because our consciousness would endure it, and we’d awake in a parallel world where that hasn’t occurred.
And because we have a limited word count here, here’s a 13-minute explanation of quantum immortality that’s worth a watch:
“If the quantum immortality theory is correct, you’re just going to wake up in a parallel universe with no memory of the fact that you just survived an apocalyptic event,” Moli said in the video.
She also detailed that our only sort of inkling into understanding that there might be a parallel world would be through the “new Mandela effects,” a phenomenon where people remember major events differently from how history claims it went.
