Or maybe he accreted the mass after collapsing?

Alternatively, maybe that’s just the weight of his massive ego?

But any knowledge you gain will change your behavior in the future, it’s unavoidable, and those changes will compound causing the divergence to grow over time.

The only way to avoid “erasing” the timeline is to propose a time travel mechanism through which the timeline never changes despite passing information to the past, and that’d be basically what I suggested, taken to a bit more extreme of a conclusion - that because any other possibility would cause a paradox, your future self must have already made the optimal choice and will be satisfied telling your past self what they already heard in the past themselves.

Well, either that, or you just continue existing in a different timeline, with no benefit from helping your past self.

This seems like a completely pointless comment. If moneymaking efforts won’t work because of the paradox of changing the future, then nothing else will work, since anything will change the future. In that situation, if given the opportunity, why not try?

Also, this can be resolved if your relative future self is smart enough to remember what they heard in the past, and say the same thing they heard when the time comes (unless it doesn’t work, in which case arguably they’d say something else, which leads to an unstable configuration where the theoretical future will change until you reach a stable configuration where future you does repeat what you heard)

Okay, but what about cat mlems and one orange braincell? Or greebles, cats being scared by cucumbers, cat circles…
