I mean, honestly, leaf through books and papers by Roger Penrose, because he is not only a great mathematician and physicist, he's a great artist as well. And he always has these amazing diagrams in his papers. So if you're a relativity kind of person, I would definitely recommend looking through Penrose's work for striking images, because they're definitely there.

And you could go either, you know, more whimsical, like the Schrodinger cat thing, or Laplace's demon. Get a tattoo of Laplace's demon. I don't know what Laplace's demon looks like, but you know what I mean. Feynman diagrams, particles interacting, you know, Feynman diagrams can get pretty complicated. They don't have to be simple ones. So I think there's all sorts of different possibilities.

If nothing immediately strikes you, I like the idea of leafing through some technical physics papers. Even if you don't understand what the papers are about, maybe you can understand like the area they're in. Are they in quantum cosmology? You know, you can read the papers by Hartle and Hawking. See if there's any images in there that strike your fancy.

And that would be something that would be pretty unique. David Whitaker says the universe is expanding and the stars and everything else are moving away from us at an increasing rate even. But they can't all be moving away from us or we'd be at the center of the universe.

And if they are moving away from us, but everything started together immediately before the Big Bang, why is everything not traveling outwards at the same speed? The great thing about this question is that the second part answers the first part. If everything was traveling outwards at the same speed, that would indeed be an indication that we were at the middle of the universe. But it's not.

So forget about moving. Forget about visualizing everything moving away from everything else. Think about, you know, the universe itself. In fact, what I like to do is to literally imagine you're outside on a clear night, and you are gifted with perfect vision, including for very, very distant galaxies, okay? So we're not using any analogies. We're just trying to visualize the real universe.

And imagine that you have Doppler imaging in your eyeballs, so you can see how fast the different galaxies are moving away from you. And you notice that galaxies that are relatively nearby are moving away from you relatively slowly. Galaxies that are far away are moving away from you faster, okay? So they're moving away from you at different speeds. what does that mean?

That means that if you think about the people who are in, who are living in one of the nearby galaxies, they see you moving away from them in one direction, and the galaxies that to you are further away are moving away from them in the other direction. Indeed, they see the same kind of pattern that you do. They see everyone moving away from them in

in a pattern which is the further away they are, the faster they're moving. So this precise behavior where everything is moving away from everything else with the property that further away things are moving away faster is exactly what you need to not have a center so that everything is created equal. Everyone sees the same basic kind of thing.

This is both what is predicted by general relativity and what is actually observed in the universe. Anonymous says, imagine a future where the NBA moves to a virtual format and all players are linked to an avatar via a brain chip. All avatars are the same height and strength.
