A major physics lab in the U.S. has found a particle, far smaller than any atom, that switches itself back and forth between being a piece of matter and a piece of anti-matter 17 trillion times each second.
It has taken 700 people in 20 countries, millions of dollars’ worth of custom equipment, vast amounts of energy, and 20 years of work to find this.
The back-and-forth switching appears to be one of the fastest processes in nature. One of the big mysteries in physics is why the universe is practically all matter, and not anti-matter. The universe once had equal amounts of both, scientists believe. more>>>
