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."

New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy's state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies.
More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope.
Scientists Detect Cosmic 'Dark Flow' Across Billions of Light Years
Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), scientists have identified an unexpected motion in distant galaxy clusters. The cause, they suggest, is the gravitational attraction of matter that lies beyond the observable universe.
Immigrant Sun: Our star could be far from where it started in Milky Way
A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such as the sun can migrate great distances.
U-M physicists' analysis leads to discovery of new particle
University of Michigan physicists played a leading role in the discovery of a new particle, the Omega b baryon, which is an exotic relative of the proton.

UCI scientists discover minimum mass for galaxies
By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe - 10 million times the mass of the sun.
Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.
Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (~redshift 7.5).
