KEY PARTICLE WEIGHS IN A BIT HEAVY, CONFOUNDING PHYSICIST

The grand explanation physicists use to describe how the universe works may have some major new flaws to patch after a fundamental particle was found to have more mass than scientists thought.

“It’s not just something is wrong,” said Dave Toback, a particle physicist at Texas A&M University and a spokesperson for the U.S. government’s Fermi National Accelerator Lab, which conducted the experiments. If replicated by other labs, “it literally means something fundamental in our understanding of nature is wrong.”

The physicists at the lab crashed particles together over ten years and measured the mass of 4 million W bosons. These subatomic particles are responsible for a fundamental force at the center of atoms, and they exist for only a fraction of a second before they decay into other particles.

“They are constantly popping in and out of existence in the quantum froth of the universe,” Toback said.

The difference in mass from what the prevailing theory of the universe predicts is too big to be a rounding error or anything that could be easily explained away, according to the study by a team of 400 scientists from around the world published in the journal Science.

The result is so extraordinary it must be confirmed by another experiment, scientists say. If confirmed, it would present one of the biggest problems yet with scientists’ detailed rulebook for the cosmos, called the standard model.
