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.

Bored Panda reached out to the curious person who asked the Redditor about the things they couldn't believe. The Redditor u/shirofromgame agreed to have a short chat with us and told us the reason behind this post. The idea for the question came to the Redditor as almost all intrusive thoughts do – just before falling asleep.

"I came up with the Reddit post after trying to go to sleep (and failing), and I was thinking about such facts," u/shirofromgame told Bored Panda. "You see, I was so sleepy that I wrote the question on Reddit and immediately fell asleep after. I actually remembered I wrote it after two days and was surprised to see it had so many replies," the Redditor adds to her whimsical story.

Out of so many interesting replies, u/shirofromgame says that the very top one messed with them the most. It was the one about how our eyes work. "I really can't get my mind wrapped around [that]," the Redditor says, "About how our brains flip the image that we see from our eyes."

    Admittedly, it is quite fascinating – our eyes actually do work like a Camera Obscura. As the specialist in neuro-ophthalmology, Dr. Andrew G. Lee, explains, the image we see is inverted on the retina. It's the retina that sees the world upside down. "Your cortex just turns it upside down," Lee says.

    ADVERTISEMENT

    There's also an interesting experiment related to the whole phenomenon. If a person were to wear prism glasses (which do the opposite), they would see the world upside down. But what's interesting is that after they take the glasses off, the whole world would be upside down for them for a few days. How does it go back to normal? "[Your] cortex puts it back in the right orientation," Dr. Lee explains.

    The solution to the Monty Hall paradox. I can even do the math myself. But it still "feels" intuitively wrong.

    The scenario: you're on a game show and the host offers you a choice between three doors. Behind one door is a million dollars. Behind the other two doors, you get nothing.

    You make your choice. But before the host opens the door to reveal what's inside, he opens one of the *other two* doors to reveal nothing behind *that* one. He then offers you a second choice: do you keep the door that you already chose? Or do you switch to the other unopened door? Does it matter?

    Intuitively, it feels like it shouldn't matter, that you have a 50-50 chance of winning whether you switch to the other door, or keep the one you chose originally.

    Mathematical reality: you should switch. You have double the chance of winning the money if you switch to the other door, compared with staying put.

    Close second: in any random group of just 23 people you will have more than 50% chance that at least two of them will share the same birthday. Again, I can do the math to prove this but it still doesn't feel right.

    I refuse to believe that ALL snowflakes in the entirety of history are unique.

    You mean to tell me, that ALL snowflakes EVER, across the ENTIRE GLOBE, are COMPLETELY UNIQUE?

    That can’t be mathematically possible. Like, a single storm that drops 3 inches on my house must be a million flakes. Multiply that by the area of that storm, and the depth of the snow, and that number becomes huge. THEN, add that to every storm in the history of the whole globe.

    I just can’t believe that we have seen every snowflake and have come to the definite conclusion that they’re all unique. Scientists aren’t at my house cataloging the snowflakes. How do they know?.

    They found an identical snowflake. I can't remember who 'they' are, but that's actually now been disproven now, I belive, as it's now been discovered that there are identical snowflakes. Or, rather, identical patterns formed. And it's also been proven to do with the weather conditions. So basically the weather, the area, altitude, etc, dictates the various shapes of the snowflakes that will fall

    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.

    Not really "refuse to believe", more "having a really hard time to wrap my head around it":


    The survival of the human race (especially in relation to how time- and work intensive our reproduction is.)


    I know amazing leaps were done in fertility treatment, reproduction medicine and infant care!


    Yet, at it's core, it's still the same process: the offspring has to be grown for (roughly) 40 weeks, inside a female body.
    It takes hours, sometimes even days, of heavy pain to birth the offspring.
    And even when that's done, human babies are 100% helpless and dependant on someone, for a good while. Sometimes, one even just "forgets how to breathe" and dies.


    Somehow we still managed to grow in population by...a hell of a lot.


    It boggles my mind, how biology hasn't found a safer, less time and work intensive way for us to reproduce, yet our population exploded.

    In my opinion, this topic has not been studied sufficiently and widely enough, because in the world of science/medicine, researching women has been perceived as difficult precisely because of hormonal activity. According to research, during the menstrual cycle, a woman secretes two different pheromones. The more recognized one is secreted during ovulation, but another pheromone is secreted after menstruation. Why couldn't these affect the menstrual cycles of women who live together or spend time together closely, if they don't use hormonal contraception.
