The Belter Home Asteroid: An Iron Sky

THE ATLANTIC | DISPATCHES FROM THE BELT March 2102 The Iron Sky Thirty-seven years ago, a crew of mutineers hollowed out a dead protoplanetary core. Today, their grandchildren argue about zoning laws, honeybees, and whether the bearings holding up their world can take one more floor.

Then you open your eyes, and your inner ear briefly stages a revolt. Three hundred meters ahead, the gra...

What If Dark Matter Doesn’t Exist—And We’re Feeling the Gravity of Neighboring Universes? After 40 years of coming up empty-handed in underground particle traps, a cleaner explanation hides in plain sight: ordinary stars, black holes, and cosmic geometry folded right next door. Pick up a handful of backyard dirt and you are holding the ultimate magic trick of physics. Virtually every heavy atom in your palm—the silicon in the sand, the oxygen in the clay, the iron giving it color—was cooked inside the nuclear furnace of a massive star that exploded billions of years ago. Nature didn’t need ninety different recipes to build the periodic table; it just took hydrogen, applied gravity and pressure, and snapped protons and neutrons together like Lego bricks. The deeper we look at nature, the simpler the rules usually get. Which is why modern cosmology currently has a massive credibility problem. According to the textbook model of the universe, all the "normal" stuff we ca...
