According to this [1] article:
> At the distance of Betelgeuse, by 960 years this shell would be 14 times the diameter of the full moon! At about 95,000 years after detonation, this slow-moving plasma will finally reach the solar system. From then-on, we will be inside the volume of intense x-rays and high-energy particles.
at least from what I can understand (I'm not an astrophysicist),
we would have 96k years to leave the solar system or adapt ourselfs to living in a plasma cloud.

- _ph_ 6y agoAs the article says, the effect wouldn't affect earth much if at all. At worst, space travel would have to cope with the increased radiation levels.
- mhaberl 6y ago>From then-on, we will be inside the volume of intense x-rays and high-energy particles. It goes on saying that the high-energy particles would not be a big deal. I guess x-rays are a different story. So saying that "the effect wouldn't affect earth much if at all" probably not correct. But then again, in a 100k years we probably won't care one way or the other. We will either be super advanced by then or won't exist.
- crispyporkbites 6y agoIf that were the case, what a fascinating problem for the human race. Imagine knowing we have 95k years to escape the solar system, what would we do? What would it mean for humanity in the next 1000, 5000 and 10000 years?
- flukus 6y ago> what would we do? Some combination of procrastination and denying the problem exists.
