Making Something From Nothing: Researchers Find That Matter Can Be Conjured from a Vacuum
From Nothing, Something A new theory suggests particles can be produced from a vacuum under certain conditions, like those found near pulsars like the one modeled here. NASA It is often said that you can't get something for nothing, but a handful of scientists from the University of Michigan would beg to differ. Theoretically speaking, they say, you can conjure particles from a vacuum under the right conditions. All you need is an ultra-high-intensity laser, a particle accelerator, and an open mind about what exactly "nothing" is (hint: it's something). The first step in understanding their line of thinking is to change the way you look at a vacuum; rather than being an empty void, they say, a vacuum is a balanced combination of matter and antimatter, or particles and antiparticles. These particles have tremendous density but we cannot observe them, for their observable characteristics cancel each other out. The researchers have devised...
