Science!: What’s Waiting to Kill Us All?
Wednesday, July 14th, 2010There are a number of events that Science! says we need to be worried about in the future. For one, in five billion years the sun is supposed to enter a red giant phase and engulf the earth. Pretty bad, but that’s a long way off, so we can safely leave it as someone else’s problem.
Except we have an earlier problem. The Andromeda galaxy is on a collision course with the Milky Way. And when it collides, who knows what will happen to our solar system? And that’s in only 4.5 billion years by current estimates.
But we have other problems besides that to worry about, as before the sun enters its red giant phase, it is constantly burning off fuel and getting hotter. It’s getting so hot, in fact, that in around 500 million years the earth should be unlivable. Yeah, that’s right: Only 500 million years. That’s something we have to think about dealing with.
If we live that long.
Because now scientists say they’ve noticed a periodic extinction pattern. Every 27 million years, something just starts killing things right and left. And the next one occurs in only 16 million years. That’s cutting it close, but that gives us time to prepare, right? But here’s the problem: Scientists have no idea what causes it.
That’s right; no idea. Usually scientists would at least act like they figured it out and make a wild guess. But this one is too mysterious to even attempt an explanation. But if something is mysterious and murderous, that points to only one culprit:
