That's really cool. Definitely helpful in order to drop deceleration fuel requirements if we ever manage to put together a relativistic interstellar spacecraft.

- phkahler 6y agoIn a bit over 1M years another star is expected to pass around 1000 AU from the sun. Chemical rockets should be able to get there in a decade or two. It's a huge stretch, but we have a million years to prepare.
- sq_ 6y agoOh wow. Had never heard about that. Wouldn't that pass within the range of the Oort Cloud? Seems like we might have some issues from the gravitational effects if so (although that's assuming humans manage to keep ourselves going for another million years).
- Koshkin 6y agoSomething makes me doubt that humans will still be around at that time.
- sq_ 6y agoWith the way we’re going, maybe not. But maybe we’ll shape up and some version of humanity will make it.
