Time....

[F2d5thCav]

I used to poo-poo the notion of time travelers, but this relatively recent business with the Mandela Effect stories has got me wondering:

Did someone figure out how to go back to the past and "screw something up" such that out timeline changed, but not our memories of how certain details existed in the original timeline?

Something seems off, and I gain a sense that the "offness" of it is growing.

Cheers
