Theoretical breakthrough: Generating matter and antimatter from the vacuum
Under just the right conditions—which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator—it could be possible to create something out of nothing, according to University of Michigan researchers.
The scientists and engineers have developed new equations that show how a high-energy electron beam combined with an intense laser pulse could rip apart a vacuum into its fundamental matter and antimatter components, and set off a cascade of events that generates additional pairs of particles and antiparticles.
“We can now calculate how, from a single electron, several hundred particles can be produced. We believe this happens in nature near pulsars and neutron stars,” said Igor Sokolov, an engineering research scientist who conducted this research along with associate research scientist John Nees, emeritus electrical engineering professor Gerard Mourou and their colleagues in France.
At the heart of this work is the idea that a vacuum is not exactly nothing.
