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.

Black Hole Confirmed In Milky Way
February 19th, 2009
admin 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 ….
Galaxy Has ‘Billions Of Earths’
February 16th, 2009
admin From The BBC:There could be one hundred billion Earth-like planets in our galaxy, a US conference has heard.Dr Alan Boss of the Carnegie Institution of Science said many of these worlds could be inhabited by simple lifeforms.He was speaking at the annual meeting of the American Association for the Advancement of Science in Chicago.So far, telescopes have been able to detect just over 300 planets outside our Solar System.Very few of these would be capable of supporting life, however. Most are gas giants like our Jupiter; and many orbit so close to their parent stars that any microbes would have to survive roasting temperatures.But, based on the limited numbers of planets found so far, Dr Boss has estimated that each Sun-like star has on average one “Earth-like” planet.Read more ….
Study Takes Step Toward Erasing Bad Memories
February 15th, 2009
admin Image from The Daily Galaxy:From Zimbio:LONDON, Feb 15 (Reuters) – A widely available blood pressure pill could one day help people erase bad memories, perhaps treating some anxiety disorders and phobias, according to a Dutch study published on Sunday.The generic beta-blocker propranolol significantly weakened people’s fearful memories of spiders among a group of healthy volunteers who took it, said Merel Kindt, a psychologist at the University of Amsterdam, who led the study.”We could show that the fear response went away, which suggests the memory was weakened,” Kindt said in a telephone interview.Read more ….
Intelligent Life Could Be Thriving On 40,000 Planets
February 5th, 2009
admin This planet, located near the centre of the Milky Way about 20,000 light years from us, is just one of the 40,000 which could be harbouring intelligent lifeFrom Daily Mail:Science’s quest to discover life on Mars has so far failed to find even one little green man.But not to worry. Aliens could be alive and well on almost 40,000 other planets.Researchers have calculated that up to 37,964 worlds in our galaxy are hospitable enough to be home to creatures at least as intelligent as ourselves.Astrophysicist Duncan Forgan created a computer programme that collated all the data on the 330 or so planets known to man and worked out what proportion would have conditions suitable for life.The estimate, which took into account factors such as temperature and availability of water and minerals, was then extrapolated across the Milky Way.Three scenarios of how life could develop were also taken into account.Read more ….
Action Sunrise At The Very Large Array
January 31st, 2009
admin From Live Science:Astronomers recently used the NSF’s Very Large Array (VLA) radio telescope (above) to help find the most distant water yet seen in the Universe, in a galaxy more than 11 billion light-years from Earth. Previously, the most distant water had been seen in a galaxy less than 7 billion light-years from Earth.The soggy galaxy is dubbed MG J0414+0534.
Six Biggest Mysteries Of Our Solar System
January 28th, 2009
admin So far as we know, our solar system is unique in the universe (Image: Nigel Hawtin)From The New Scientist:ONCE upon a time, 4.6 billion years ago, something was brewing in an unremarkable backwater of the Milky Way. The ragbag of stuff that suffuses the inconsequential, in-between bits of all galaxies – hydrogen and helium gas with just a sprinkling of solid dust – had begun to condense and form molecules.
