Some science facts can be pretty wild. Like this fun fact about grasshoppers. Did you know that their ears are actually on their bellies? And not just one pair of ears. They apparently have six along the sides of their abdomens! This is the kind of fact that I find quite hard to wrap my head around.
So I totally get why one Redditor went to r/AskReddit and posed a similar question to other netizens. The user u/shirofromgame wrote: "What is a scientifically proven fact you refuse to believe?" And the 'refuse to believe' part in this case is not that they actually don't believe it. It's more that the fact is so outlandish or ridiculous that it just blows their mind.

That cold plunges are good for your health. Can’t do it. Not going to submerse myself if freezing water.

That many living people have Neanderthal DNA. Mostly in non-African ethnicities. My DNA is apparently more 'Neanderthal' than 93% of the population tested to date by 23andme. WTF? THat many living people have the DNA of another non-modern species (is that the right word?), the Denisovans (mostly certain Asian ethnicities). How many more non-modern species of DNA do humans carry that we just have not identified? How many others did we interbreed with? WHAT ARE WE?

That jet planes can fly. Come on.
I’ve flown on them many times before.
But come on.

Humans are made up of 70% water, just doesn’t make sense. Too many bones and muscle for such a high number.

That dark matter / energy exists. We've yet to directly observe any of it, only the indirect effects via gravity, and even Einstein himself acknowledged that his model of physics was incomplete. We understand gravity now better than Newton did, but there are still gaps.
While the body of evidence supporting dark matter theory is extensive, we're one step away from demolishing and reinventing all of modern physics. One day a new Einstein will come along and invent an even more robust model of gravity, and it could reveal that our supposed "dark matter" was really the result of a huge flaw.

The levels of crazy my kids can reach after having a marshmallow, or any junk food for that matter, makes me not believe that sugar doesn’t cause hyperactivity.
