The diet; the microplastics that you eat, drink and breathe; the endocrine disruptors that you huff from your home’s PCB-finished wood floor, or dishwasher detergent buildup inside you; extremely hygienic environments which make for overeager immune systems; pollution; the pesticides that Monsanto assured you are totally safe and go great with their proprietary genemodded sterile cereals which they also assure are totally safe; the near-eternal organofluorides you get exposed to because there’s a chemical plant 100km upriver with a gung-ho attitude towards waste disposal, and all the slightly scratched Teflon pans you kept using because it’s fine; or the trillion other things we’re doing to fuck up just about literally everything that lives anywhere on this planet, including our own sorry asses
I’m middle-aged so I’ve already had more than my fair share of fun (I’m great at taking the ‘fun’ out of ‘too much fun’), but I think my warranty expired a few years ago. I got a new and exciting autoimmune disorder and this stupid meat suit is almost literally self-destructing
I have absolutely no idea what a “chutes day” is 😅 but I’m a dirty foreigner with a native language that’s not even in the same family as English, please have mercy
Oh yeah, like an observation platform. That’s probably the only way you’d be doing time travel anyhow since it’s also space travel because the Earth now isn’t where the Earth was 200 million years ago; doing an atmospheric re-entry across time when you’re not 100% sure where exactly everything will be sounds like an occupational health hazard and inadvisable at best. Gods fucking help you if anything goes wrong and you violently scatter pieces of your fancy time machine across a few square km of densely populated (by animals including genus Homo) area.
Or you shedding some of your microbiome’s bacteria and fungi into the environment and whoops: they outcompeted something “local” and now whole species change.
I honestly don’t think there’d be any way to avoid doing something that could possibly change the future in a dramatic way, because that far back incredibly minute changes could possibly lead to huge differences (because chaos theory), to the level of “a butterfly didn’t flap its wings because I accidentally squashed it with my time machine, and now humanity never happened. Oops.” But any change that means you didn’t ever go on your trip means you have some sort of paradox on your hands, and then it becomes a question of how timelines work
