If you get up any morning for the next few weeks, you'll be treated to the sight of all the planets except Saturn arrayed along the ecliptic, the path of the sun through the sky.
For the last two months, almost all the planets have been hiding behind the sun, but this week they all emerge and are arrayed in a grand line above the rising sun. Mercury, Venus, Mars, and Jupiter are visible, and you can add Uranus and Neptune to your count if you have binoculars or a small telescope.
Now I don't want to ruin how the world ends, but I will give you a hint: something about gravity fields and planets hitting each other. You ever seen a planet hit another one? They all punch like babies. Except Uranus -- it really packs a punch. Get it? I'M ASKING HOW IS YOUR OFFICE CHAIR NOT ON FIRE.
Thanks to matt, who's already building a bunker. Bunker or pillow fort?
