You're gonna be bothered by how cool I am.

I've seen all these theories on how far the reset goes, how far back the changes and repercussions of the bomb in 1977 go. One theory, for example, proposes that the bomb reset everything from the 1950s on, and frankly I find all this bizarre.

If they detonated the bomb in 1977, how on earth could that event have changed anything that happened before that? Sure, plenty could have changed after that, but before???
