I see three.

I crave an actual watch with no smart crap built in. IMO watches are meant to tell you the time, maybe let you set an alarm or stopwatch, and nothing else. My watch cost $25, does all of those things, and has a battery life measured in years. Anything else I need to do can be done just fine by the phone I always carry around in my pocket.

Why the shitty AI slop image?

More of a reverse supernova I'd think. You're starting with the very heavy elements and fissioning them into lighter ones.

I've never heard a nuclear bombing described as a supernova, but you do you?

Always good to do a quick search of the literature to make sure your intuition about something is actually correct; I too thought "no way" when I first saw your question.

I don't think only heating water to 500C would remove more harmful chemicals than a typical full treatment process, as they have a lot of steps to filter various things out, but I don't have a source for that.

Even if it did, there's still the issue of heating up the water taking an enormous amount of energy, which is probably a dealbreaker. My local wastewater plant treats 40 million gallons a day, which by a quick calculation would take 150 GWh to heat, 83% the daily energy consumption of the whole of Minnesota. That can be reduced significantly with heat exchangers but even 1% of that would be far too expensive.

I would bring a list of supernovas that occured in my past, but in the future of the time I traveled to. A couple matching observations will provide indisputable proof that I have information from the future.

Well... The Large Hadron Collider can smash lead nuclei together at nearly the speed of light, which turns them into something that is definitely no longer lead.

Yes; this is something that has been studied. However as other commenters have said it requires a lot of energy, and is better suited for processing smaller quantities of water with a high level of PFAS contamination than massive quantities of water with an extremely low level of PFAS. It's also not a standalone solution, as plenty of harmful chemicals survive heating past 400/500C (heavy metals like cadmium, lead, and mercury do not break down at any temperature).

I don't think life has any kind of inherent meaning; it simply arose from random physical processes when the conditions were right and took off from there. I keep living mostly because it's kind of the default, and because I don't want to hurt others with my death.

The same can be said for real life. Time is a temporal dimension, not a spatial one, so everything must only move through it in one direction, and usually does so at a constant rate. (Taking relativity into account things move more slowly through time at high velocities but that's not applicable to most of our world).
