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.

Telescope Spies Cataclysmic Blast

Photo: Main facts of the Fermi Mission:Spacecraft was launched in June 2008 on a five-year missionIt is looking at the Universe in the highest-energy form of lightFermi is 2.8m (9.2ft) high and 2.4m (8.2ft) in diameterThe spacecraft orbits at an altitude of 565km (350 miles)It could pick up about 200 cosmic explosions each yearFrom The BBC:Astronomers have recorded the most powerful radiation blast from deep space yet detected.The event was observed by Nasa’s recently launched Fermi Gamma-ray Space Telescope and reported in the online edition of the journal Science.The source of the blast is assumed to be the catastrophic implosion of a star, to create a black hole.Scientists say the spectacle’s energy release was equivalent to thousands of ordinary exploding stars.Read more ….

Black Hole Confirmed In Milky Way

From BBC:There is a giant black hole at the centre of our galaxy, a 16-year study by German astronomers has confirmed.They tracked the movement of 28 stars circling the centre of the Milky Way, using two telescopes in Chile.The black hole, said to be 27,000 light years from Earth, is four million times bigger than the Sun, according to the paper in The Astrophysical Journal.Black holes are objects whose gravity is so great that nothing – including light – can escape them.According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit.Read more ….

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 Ways to Destroy Earth

Whether it took the Earth 4.5 billion years to get to where it is today (or a mere seven days), destroying it might take a lot less time. Sam Hughes presents a host of methods for ending the planet — and life — as we know it.

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.
