End of the World 10 Disasters that could end it all at any given second

Particle AcceleratorsPhysicists have long theorized that particle accelerators could destroy the earth. When electric fields are used to accelerate protons they could collide at speed fast enough to create black holes or bits of altered matter. These small black holes would slowly engulf our planet.

Nuclear Fusion Fission Hybrid Reactor To Destroy Waste

Photo from ABC News (Australia)From Future Pundit:The idea behind long term (tens or hundreds of thousands of years) nuclear waste storage facilities is that we can’t solve the nuclear waste disposal problem quickly. But matter is so manipulable in the hands of sufficiently smart scientists and technologists that sometimes supposedly insolvable problems become solvable.

The Physics of ‘The Hit’ — Superbowl Science

Baltimore running back Willis McGahee was seriously injured after a collision with the Steelers’ Ryan Clark in the A.F.C. championship game. Julie Jacobson/Associated PressFrom The New York Times:TAMPA, Fla. — Isaac Newton’s apple hurt considerably less than Ryan Clark’s coconut. But they did have a few things in common.Clark’s shockingly violent hit on the Baltimore Ravens’ Willis McGahee two Sundays ago — a full-speed, helmet-to-helmet crash that left McGahee unconscious and Clark all but — didn’t just follow the N.F.L.’s rules, but Newton’s as well.

Scientists Not So Sure ‘Doomsday Machine’ Won’t Destroy World

APFrom FOX News:Still worried that the Large Hadron Collider will create a black hole that will destroy the Earth when it’s finally switched on this summer?Um, well, you may have a point.Three physicists have reexamined the math surrounding the creation of microscopic black holes in the Switzerland-based LHC, the world’s largest particle collider, and determined that they won’t simply evaporate in a millisecond as had previously been predicted.Rather, Roberto Casadio of the University of Bologna in Italy and Sergio Fabi and Benjamin Harms of the University of Alabama say mini black holes could exist for much longer — perhaps even more than a second, a relative eternity in particle colliders, where most objects decay much faster.Read more ….

Do Naked Singularities Break the Rules of Physics?

Image: Kenn brown Mondolithic StudiosFrom Scientific American:The black hole has a troublesome sibling, the naked singularity. Physicists have long thought–hoped–it could never exist. But could it? * Conventional wisdom has it that a large star eventually collapses to a black hole, but some theoretical models suggest it might instead become a so-called naked singularity.

Top 10 Scientific Discoveries For 2008

From Time Magazine:1. Large Hadron ColliderJean-Pierre Clatot / AFP / GettyGood news! The Large Hadron Collider (LHC) — the massive particle accelerator straddling the Swiss-French border — didn’t destroy the world! The bad news: The contraption didn’t really work either. In September, the 17-mile collider was switched on for the first time, putting to rest the febrile webchatter that the machine would create an artificial black hole capable of swallowing the planet or at least a sizeable piece of Europe — a bad day no matter what.
