Summary
What is the dipole repeller? Why is it a dipole? What is it repelling? What is the Bootes Void and how is it connected to dark energy? I discuss these questions and more in today’s Ask a Spaceman!

| 0:00.0 | What's always drawn me to cosmology is the sense of scale of the universe. |
| 0:17.6 | I mean, not even sci-fi can touch this stuff. In this episode, I'm going to be |
| 0:23.6 | casually dropping names of objects that are millions of light years across at a minimum. And these |
| 0:33.7 | structures that I'm going to talk about took billions of years to evolve. |
| 0:40.2 | I mean, think of the most crazy outlandish sci-fi movie that takes place in the biggest |
| 0:45.6 | setting possible, like Star Wars is across the entire galaxy. |
| 0:49.7 | And there are 300 billion stars in a single galaxy, 300 billion stars in the Milky Way galaxy alone. |
| 0:59.5 | There's a trillion in the Andromeda galaxy. |
| 1:03.0 | And that's one galaxy. |
| 1:05.4 | In the nearest one, our nearest neighbor, galaxy is millions of light years away, two and a half million |
| 1:12.0 | light years away to get to Andromeda. |
| 1:14.0 | And that's just getting started with cosmology. |
| 1:17.7 | That's just the beginning steps. |
| 1:20.9 | When I start building this map that we're going to get into to talk about today's topic, |
| 1:25.8 | which is the dipole repeller, but that's actually going to come at the very end because we need a lot of setup. |
| 1:31.2 | We're going to start. |
| 1:32.4 | Our initial picture is going to start at a scale around 10 million light years across. |
| 1:39.1 | 10 million light years. |
| 1:43.5 | Our nearest neighbor star to the sun is less than four light years away. |
| 1:50.5 | And this is always drawn me. This is always just the weirdness of it that I can build a computer |
| 2:00.6 | program to simulate the evolution of the universe, that I can build a computer program to simulate the evolution of the universe, |
| 2:03.9 | that I can write down an equation that describes the interaction between two galaxies, |
