The other night, I was outside, just looking up, and I noticed the constellation Orion.
If I recall correctly, they say it should explode and die sometime in the next 10,000 years. Now that doesn't mean it'll be that long, just that we don't know exactly when it will happen.
It could be 10,000 years from now. It could be next year. It could be next week. It could be tomorrow. Or...
It could have already happened, and the light of the explosion just hasn't reached us yet.
