memes scientists use to teach people by metaphor.

imagine you had a piece of paper. ordinarily, you would have to travel across the surface. but if you folded it like *this* and poked a pencil through it, then you can travel from point A to point B in no time at all

imagine you had a trampoline. and u put a bowling ball in the middle of it. and u put a marble on the trampoline. gravity.

imagine u had some finches on some islands. they look different and darwin figured it. out. ur so cool darwin

imagine u aimed a cannon. you destroy a lot of arable land by firing cannonballs at the ground at escape velocity but eventually u get the angle right and it enters orbit

imagine. the Stanford prison experiment

imagine u were a ballerina. if you are compressed into a ball you move quickly, and vice versa. like a star. u are a star

imagine a flea on a tightrope. look at that lil guy go

imagine you had white moths and you covered them in soot. they're black now. and so are the trees

black holes look like a shower drain

butterflies cause hurricanes on the other side of the world. so if you ever see a butterfly, make sure you kill it -- you might save a life.

a higher number of hurricanes during hurricane season isn't because of global warming -- the butterfly population is growing. they're coming.

As @solarpunk has learned, there are more stars in the night sky than there are grains of sand on Earth

@solarpunk Oddly enough, we have more trees on Earth than stars in the galaxy

@seb *holds up a piece of paper* okay, here's the universe as we know it. You're on one side, and whatever beyond the event horizon lies on the other side of the paper. *Uses pen to poke a hole in the paper* and kids, this is how much energy it takes to go to the other side. Simple physics.

@philectron we're gonna need a pretty big pencil

@seb Imagine cataloging each one.

@solarpunk @seb it's okay, they're all Earth trees.. that's it. No catalog needed. All other differences can be chalked up to genetic variation, like different hoomans
