In 8,000 years.
Am I reading that right, or should I dig a hole now?
Digging a hole might not be a bad idea - it could have blown up 8,000 years ago and we don't know it yet.
But, the article keeps using the word "nearly" a lot, as in the spiral is "nearly" pointing towards Earth. In astronomical terms, "nearly" can mean several hundred light years. Even if we are out of the bullseye by a small fraction of a percent, the amount of distance between us and that star would put is easily within the safety zone. We have a better chance of being hit by an asteroid.
