An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.

The internet to me is kind of like a black hole, and I never really go on it.

In nuclear war all men are cremated equal.

Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global nuclear war, a genetically engineered virus or other dangers we have not yet thought of.

I'm still bothered by the threat of nuclear war.

You’re universally liked because you’re such a black hole in space. You don’t have any real traits. You’re sympa, at least as much as a narcissist can be, but that means nothing. You’re beautiful and everybody projects onto you what they’re looking for, which is easy to do since you don’t stand for anything definite. You’re a black hole in space.
