This thread reminds me of Sliders, and the problem I always had with trying to find your way back from infinite possibilities. While sure, dinosaurs never dying or no one discovering penicillin are possible timelines, so are the ones where I turned on the light in the bedroom so I didn't stub my toe. Or cutting my hair last week instead of today.

So the Sliders should have come across a billion versions where the only difference was that someone decided to mow their grass in India on a different day of the week than normal and have been perfectly fine staying there.
