Noise proves nothing. Often a hen who has merely laid an egg cackles as if she laid an asteroid.
Imagine a giant asteroid on a direct collision course with Earth.
That is the equivalent of what we face now [with climate change], yet we dither.
Our biggest threat is not an asteroid about to crash into us, something we can do nothing about. Instead, all the major threats facing us today are problems entirely of our own making. And since we made the problems, we can also solve the problems.
We are involved in technology development for, you know, missions that we hope to plan that would take us to an asteroid and eventually to Mars.
This planet is 15 million years overdue for an asteroid strike like the one that killed the dinosaurs.
We need to take command of the solar system to gain that wealth, and to escape the sea of paper our government is becoming, and for some decent chance of stopping a Dinosaur Killer asteroid.
I despise the Lottery. There's less chance of you becoming a millionaire than there is of getting hit on the head by a passing asteroid.
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.
Asteroids have us in our sight. The dinosaurs didn't have a space program, so they're not here to talk about this problem. We are, and we have the power to do something about it. I don't want to be the embarrassment of the galaxy, to have had the power to deflect an asteroid, and then not, and end up going extinct.
I don't want to be the embarrassment of the galaxy to have had the power to deflect an asteroid, and then not and end up going extinct. We'd be the laughingstock of the aliens of the cosmos if that were the case.
