Apparently people still think that the earth is flat despite an overwhelming amount of evidence to the contrary. This stuff is all over social media, and it infuriates me to no end because we’ve known that the earth was a sphere for thousands of years, and if ancient man could figure that shit out then I would expect that someone who has access to satellite photography would also be able to figure it out. But alas, people are ignorant as fuck and thus we have the flat earth theory. Everyone’s favorite astrophysicist, Neil deGrasse Tyson, recently had to respond to an NBA star commenting that the earth is flat.
I had an exchange with someone on Instagram earlier today. Someone I follow posted something showing how the earth was curved, not flat. Well, cue the “woke” enlightened folk. So I asked how a flat planet could form in the presence of gravity. Well, apparently gravity is also a conspiracy. Here’s the response I got:
See, guys, there’s no such thing as gravity because density! Duh. And no, I’m not blurring anyone’s name out on here because if you’re stupid enough to think the earth is flat and gravity isn’t real you deserve to be called out. And yes, I also realize that you all have my Instagram handle now.
But here’s why I asked about gravity.
I wanted to think of a proof or a thought experiment I could give a flat earther to get them to realize that they’re wrong. And I think I came up with one. And it all hinges on gravity. In order for a flat planet to form, gravity either 1) needs to not exist, or 2) not behave according to our current models. My response to good ol’ Jonathan there was this:
“There’s a very easy way to prove whether or not gravity is real. Pick an object, any old object will do. Next, find a place you can drop it from–a second story window, a tree, a rooftop–it doesn’t matter. Now, if you know the mass of the object and the height from which you’re dropping it from, then it’s a matter of simple math. Calculate the time it would take the object to reach the ground 1) by using the standard model of gravity and the equation time = √(2d/g) and 2) by substituting the value of g for literally anything else–like the formula for density. Then drop the object and compare the times to those given by your two equations.”
That’s really something any middle school student should be able to do. The response I got?
…total crickets. Nobody had a response. None of the flat earth geniuses, to nobody’s surprise, derived a new form of math to describe acceleration and motion that didn’t use gravity.
Because you can believe that the government lies to us about the shape of the earth and the ISS and moon landing are faked by NASA, but there’s one thing that doesn’t lie–GODDAMN MATH.
But just the fact that this needs to be explained to people is incredibly disheartening. It speaks to a broken education system. It speaks to a culture steeped in paranoia. It speaks to a political system wherein people are encouraged to openly deny evidence. People are so quick to latch onto conspiracy, but they can’t see that the way to to truly keep someone ignorant is to make them question observable, measurable, testable, repeatable evidence. THAT’S how you keep someone in ignorance. And the fact that this is happening speaks volumes about our social and political state.
So if you ever run into a flat earther, give them this proof and see what happens. My guess it that cognitive dissonance will be so great that their head will explode.
