Press invitation: Big bucks for Big Bang scientists
May 07, 2002A £1.7 million science laboratory for studying one of the great mysteries of the Universe opens at the University of Sussex on May 14, 2002.
The Centre for the Measurement of Particle Electric Dipole Moments has been equipped with the very latest technology to help scientists discover what happened in the aftermath of the 'Big Bang'.
Ed Hinds, professor of experimental physics and director of the new centre, says: "This is a unique and very exciting project. We hope eventually to find out what happened between 'matter' and 'anti-matter' when the Universe was created."
The question that has vexed scientists and astronomers for decades is why there is more matter in the Universe than anti-matter. Both were formed at the time of the Big Bang, which is predicted to have been about 15 billion years ago. For every particle formed, an anti-particle should also have been formed. Almost immediately, however, the equal numbers of particles and anti-particles would have annihilated each other, leaving nothing but light. The theory is that somehow - we do not know how - more particles must have been created than anti-particles, which is how the stars and planets came into existence.
Anti-matter now exists only at the sub-atomic level. Prof Hinds and his team therefore need high-powered microscopes and lasers for their study. The work involves looking at neutrons and electrons within atoms and measuring the distribution of their electric charge, or their "electric dipole moment".
"We haven't yet been able to see these dipole moments," says Prof Hinds, who has spent the past 20 years in this area of research. "But with advancing technology, we're now on the verge of a breakthrough."

Big Bang Current Events and Big Bang News RSSExoplanets clue to sun's curious chemistry
"For almost 10 years we have tried to find out what distinguishes stars with planetary systems from their barren cousins," says Garik Israelian, lead author of a paper appearing this week in the journal Nature. "We have now found that the amount of lithium in Sun-like stars depends on whether or not they have planets."
Rapid star formation spotted in 'stellar nurseries' of infant galaxies
The Universe's infant galaxies enjoyed rapid growth spurts forming stars like our sun at a rate of up to 50 stars a year, according to scientists at Durham University.
'Dropouts' pinpoint earliest galaxies
Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang.
Blast from the past gives clues about early universe
Astronomers using the National Science Foundation's Very Large Array (VLA) radio telescope have gained tantalizing insights into the nature of the most distant object ever observed in the Universe -- a gigantic stellar explosion known as a Gamma Ray Burst (GRB).
Vanderbilt astronomers participate in new search for dark energy
The most ambitious attempt yet to trace the history of the universe has seen "first light." The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey III (SDSS-III), took its first astronomical data on the night of Sept. 14-15 at the Sloan Foundation telescope in New Mexico.
James Webb Space Telescope Begins to Take Shape at Goddard
NASA's James Webb Space Telescope is starting to come together. A major component of the telescope, the Integrated Science Instrument Module structure, recently arrived at NASA Goddard Space Flight Center in Greenbelt, Md. for testing in the Spacecraft Systems Development and Integration Facility.
To understand the universe, science calls on the ultrasmall
Will the universe expand outward for all of eternity and end in a vast, dark, cold, sterile, diffuse nothingness? Or will the "Big Bang" - the gargantuan explosion that formed the universe 14 billion years ago - end in the "Big Crunch?"
First Black Holes Born Starving
The first black holes in the universe had dramatic effects on their surroundings despite the fact that they were small and grew very slowly, according to recent supercomputer simulations carried out by astrophysicists Marcelo Alvarez and Tom Abel of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University, and John Wise, formerly of KIPAC and now of NASA Goddard Space Flight Center.
First black holes kept to a strict diet, study shows
A new supercomputer simulation designed to track the fate of the universe's first black holes finds that, counter to expectations, they couldn't efficiently gorge themselves on nearby gas.
Simulations Illuminate Universe's First Twin Stars
The earliest stars in the universe formed not only as individuals, but sometimes also as twins, according to a paper published today in Science Express.

The Big Bang Theory: The Complete First Season Starring: Johnny Galecki, Jim Parsons, Kaley Cuoco University physicists Leonard and Sheldon know whether to use an integral or a differential to solve the area under a curve. But they don’t have a clue about girls. Or dating. Or clothes. Or parties. Or having fun. Or, basically, life. So when a pretty blonde named Penny moves in the apartment across the hall, the guys decide to get an education outside of the classroom. Boys, you have a lot to learn. With series creators Chuck Lorre (Two and a Half Men) and Bill Prady (The Gilmore Girls) concocting the right mix of logic and lunacy and stars Johnny Galecki (Roseanne) and Jim Parsons (Judging Amy) turning geekdom into Phi Beta fun, The Big Bang Theory is big on laughs. And life. |

Howard Goodall's Big Bangs Starring: Howard Goodall Directed By: David Jeffcock;Justin Kershaw 'In this series I'm going to look at five of the great breakthroughs that European music has experienced in its extraordinary history; five momentous discoveries. I also want to show what they mean to us today, at a time when so-called classical music is being absorbed into a much bigger mainstream and when its 1,000-year reign seems to be coming to a close.' HOWARD GOODALL With intriguing anecdotes and witty humour, composer Howard Goodall presents five innovations in European musical history, which have overwhelmingly changed its course: NOTATION: the journey from plain chant in medieval times to symphonic works and improvisation EQUAL TEMPERAMENT (a universal tuning, scale and key system): from the discoveries of Pythagoras to J.S. Bach OPERA: where music interfaces with real... |

Big Bang: The Origin of the Universe (P.S.) by Simon Singh (Author) A half century ago, a shocking Washington Post headline claimed that the world began in five cataclysmic minutes rather than having existed for all time; a skeptical scientist dubbed the maverick theory the Big Bang. In this amazingly comprehensible history of the universe, Simon Singh decodes the mystery behind the Big Bang theory, lading us through the development of one of the most extraordinary, important, and awe-inspiring theories in science. |
