Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.

Sometimes I back up my argument with entire books lmao. Its not usually for the person I am arguing with. Its for the people who see the argument and are curious
You should be able to explicate your own argument, though. "Read this book" isn't convincing on its own.
Oh for sure, I don't just say, "you're wrong read this book" lol.
Yeah, this happens way too often "it's all in here (link), but I will not elaborate"
Yeah, you need to take specific portions of the book to support your argument. I won't just say "read Fanon" but will give a a specific example from the book in addition to the more general example of the entire work, plus encourage them to read more.
Einstein said if you can't explain it simply, you don't understand it.
Also drag likes your name.
Agree with that 100 % I have a degree in Philosophy and that's a reoccurring dynamic I saw with people trying to baffle with bullshit rather than make a cogent argument
I would’ve loved to hear him explain general relativity to an elementary school kid. No bowling ball on trampoline nonsense either!
There's no such thing as absolute speed in the universe. But there is relative speed. That's how fast something is going, from something else's point of view. The speedometer on your car measures your speed relative to the road. But another car on the road next to you would say your speed is 0, because from their point of view you aren't moving. That is to say, you're going the same speed.
We used to think relative speeds just added or subtracted together normally. The same rules you learned in math class. But Einstein figured out that isn't true. See, Einstein and many others knew that the relative speed of light is always the same. No matter how fast you're going, light is faster. And always by the same amount. You can never get closer to the speed of light. It didn't make sense to anyone until Einstein figured it out.
Einstein realised that the faster you're going, the slower time passes. So even if you're going at a million miles an hour, you just slow down, and now from your fast/slow point of view, light is still beating your speed by the same amount. You don't experience time as slower, but anyone looking at you would see you moving in slow motion.
That's how drag's high school physics teacher explained it to drag. Drag oversimplified a bit, but all the important bits are there, and anyone could figure out the rest if they spent the time thinking about it. Anyone who thinks relativity is hard to explain doesn't understand it. That's what Einstein was saying.
That’s special relativity. General relativity is the theory of the curvature of spacetime as the mechanism for gravity. Large masses curve spacetime more than small masses. Under GR, gravity is not a force.
Good point but why "no bowling ball on a trampoline nonsense"? That's not a correct analogy, since it deforms "space" different from how gravity transforms space, but it's good enough to understand how that works, I think
Oh because that incorrect analogy is the most common “lay person” analogy for describing gravitational curvature of spacetime. The most common reply from children is that it’s the earth’s gravity pulling down on the bowling ball so that the trampoline demonstration wouldn’t work in space.
Also the trampoline analogy doesn’t show us how gravitational lensing works, nor does it even touch how different gravitational reference frames affect the passage of time (GR generalizes special relativity, after all).
Affecting passage of time looks like a difficult idea to come up with an analogy.
For the better gravity analogy, I think a rubber sheet that has something pulling together at a "gravity well" and lines drawn on it may work better, but I'm not sure 😅
The harder thing to convey is the full dimensionality of it. With the rubber sheet (or trampoline) you can show a small ball orbiting around a larger one but only in a single plane (around the “equator” of the large ball). However in reality you can orbit in any direction you like and many satellites actually orbit over the poles. Trying to show that with a small model seems extremely difficult!
Furthermore, most children are raised on the idea that gravity is pulling them down. They intuitively understand the idea that when they climb a ladder and drop a ball from the top, the earth pulls the ball down. General relativity tells us that this is not happening at all! That there us nothing pulling us down whatsoever. I have yet to see anyone provide a lay person GR explanation for the ladder problem.
Not in Australia, though
Honestly such a power move
Just point to the dictionary. "Draw your own conclusions, bro"
