Anyone come up with a good measure of distance that makes the speed of light a nice round number? I like the metric system, but the meter feels pretty arbitrary. We could do better!
I think it's (1 Planck length / 1 Planck time). If you take the smallest distance that exists and divide it by the shortest amount of time that can pass, you have exactly c.
btw that's a nonsensical argument. there can be both space and time smaller than that.
https://en.wikipedia.org/wiki/Planck_units#Planck_length
Same is true for the Planck time, although the English Wikipedia is oddly blank for that one: there can be no space or time smaller than that within the physics that we have come up with.
welllll i say that's a reaaaly sketchy and irrational way to look at things.
like, even if you smallest ruler is 1 mm, that does not mean that smaller things don't exist. they can still play a role, i.e. through chaotic behavior smaller perturbations could be up-amplified until they are measurable.
Okay? You be you, I guess. I mean, stupid physicist eggheads, what do they know?
i don't like trusting "experts" in fact. trusting "experts" is how we got into this mess. people let themselves be manipulated by the media. people need to think for themselves. yes, that includes not believing certain scientific results, but IMO it's better to discard a scientific result that i cannot follow myself instead of becoming an authoritarian (i.e. one who believes in authors, i.e. other people's writing) dependent.
Aaaahhhhh, you're one of those... Good to know. Yeah, your reply makes sense then. Also thanks for telling me early in the discussion that you're just a science denialist, then we don't need to waste precious time with a discussion about things that you'll just disregard at will anyway.
by the way i'm not a science denialist, i just cannot follow that one particular argument (about the planck length).
Can't make that shit up.
Also, just to follow up on this, it's for the largest part not scientists that got us into this mess, whatever in particular that may be. The world would be much better off if people had more trust in science. That's too much to demand though it seems, especially from boomers. So here we are, with populists and companies messing stuff up and people like you blaming scientists for the results.
ok, go measure it then dumbass
