You emit light. Mm-hmm. So dark matter wouldn't be dark, maybe.

That's a good question. Like the perturbations of time travel. This is a good time to bring up the Andromeda Paradox.

What happened?

What happened?

Well, the Andromeda paradox is the fact that if you and I are looking at Andromeda. Andromeda, the galaxy. The galaxy.

Not the Andromeda strain, right? Two and a half million light years away. Then what happens is, suppose you're sitting in your chair and I'm running by. And at the second I run by you, we both look up at Andromeda. Because I'm moving and you're stationary, we're gonna see events that are days apart, even though we're in the same location looking at the same time.

And you think that relativity, and you think that the light arriving. Don't just say relativity and keep talking.

You're in the same place. We're in the same place, essentially.

It's a little known paradox.

Well, here's what you would think. You would think the light is arriving right now. We should all be receiving this light, but that's not how it works. motion changes the perception of time. And so we know about that in terms of the local universe. We call it relativity of simultaneity, right? You're moving, I'm not. You see events as simultaneous.

I see them as happening one before the other, right? But then when you add the distance component in it, now we see very different times. So there could be a third person moving in the other direction seeing a different time. So how do you define what now is? So we don't even understand time.
