| 0:00.0 | We've come a long way. Let's see where that journey leads a million years from now. |
| 0:07.0 | A million is a funny number. It's big enough to feel almost abstract, whether we're talking about years in the future or subscribers on this channel. |
| 0:17.0 | And as we hit that milestone, it felt like a good time to ask a much bigger question. |
| 0:22.9 | What does humanity look like in the year 1 million AD? By then, we may have spread across the |
| 0:28.8 | galaxy, reshaped our bodies and minds, and learned to experience time in ways that make a million |
| 0:34.9 | years feel like a lifetime, or a long weekend. We may not even |
| 0:40.1 | agree on what it means to be human anymore. There's also a chance that some of us alive today |
| 0:45.4 | might still be around to find out. So, grab a drink and a snack, subscribe if you're not one of the |
| 0:52.5 | million folks who already have. And let's |
| 0:54.8 | take a look at the year 1 million AD. |
| 0:59.9 | The Galaxy by 1 Million AD. When we talk about a million years in the future, the first |
| 1:05.7 | question we have to ask is a simple one. How far could we actually go? Because the galaxy is big, but not that big. |
| 1:14.7 | The Milky Way is about 100,000 light years across, surrounded by a halo of stars and dwarf galaxies |
| 1:20.7 | extending even further out. That sounds enormous, and it is, but on a million-year time scale, it becomes surprisingly |
| 1:29.1 | manageable. |
| 1:30.6 | If you travel at or near the speed of light, you can cross the galaxy multiple times in that span. |
| 1:36.8 | Even at just 10% of light speed, you can still traverse the entire galaxy in a million years, |
| 1:42.4 | and that's assuming a fairly conservative approach to |
| 1:44.8 | interstellar travel. |
| 1:46.5 | We have ship designs like Orion or Medusa that can probably get us to a few percent of |
| 1:51.2 | light speed, and it would let us get to most of the galaxy by then. |
| 1:55.2 | If we have options like nuclear fusion or antimatter or bean proportion, which I think we |
