What is the Andromeda paradox?
Well, the Andromeda paradox is the fact that if you and I are looking at Andromeda, Andromeda, the galaxy, the galaxy, 2 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 going to see events that are days apart even though we're in the same location at the same time. And relativity and you think that relativity and keep talking.
In this scenario, how far away from me are you when you're running by same place?
We're in the same place essentially. 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. So, how do you define what now is? Even though you're in the same time. Even though you're in the same place, while we're sitting here, I'm here. You're running by. We look up at the drama at the same time. And we're seeing something from the same location. Essentially, we're seeing things apart.
Days apart.
And that leads to the idea of what is now. And your now and my now are two different now.
There's no. There is now.
