Decades later, an international collaboration of scientists decided to rerun the experiments with an even higher degree of precision. The team raced muons around a magnetic, ring-shaped track — the same one used in Brookhaven’s experiment — and studied their signature wiggle at the Fermi National Accelerator Laboratory near Chicago.The first two sets of results — unveiled in 2021 and 2023 — seemed to confirm the muons’ weird behavior, prompting theoretical physicists to try to reconcile the new measurements with the Standard Model.

Now, the group has completed the experiment and released a measurement of the muon’s wobble that agrees with what they found before, using more than double the amount of data compared to 2023. They submitted their results to the journal Physical Review Letters.That said, it’s not yet closing time for our most basic understanding of what’s holding the universe together. While the muons raced around their track, other scientists found a way to more closely reconcile their behavior with the Standard Model with the help of supercomputers.There’s still more work to be done as researchers continue to put their heads together and future experiments take a stab at measuring the muon wobble — including one at the Japan Proton Accelerator Research Complex that’s expected to start near the end of the decade. Scientists also are still analyzing the final muon data to see if they can glean information about other mysterious entities like dark matter.

“This measurement will remain a benchmark ... for many years to come,” said Marco Incagli with the National Institute for Nuclear Physics in Italy.By wrangling muons, scientists are striving to answer fundamental questions that have long puzzled humanity, said Peter Winter with Argonne National Laboratory.

“Aren’t we all curious to understand how the universe works?” said Winter.

From 1942 to 1944, the company built more than 150 airships for the Navy to serve in World War II, flying patrol over warships on the seas with zero reported loss of ships when a blimp was on watch.The Goodyear Blimp has been a regular at major sporting events since flying above the 1955 Rose Bowl. A few years later, it became a service vehicle for television coverage while simultaneously functioning as a highly visible advertising platform.

Since that time, blimps have undergone wholesale changes and improved dramatically: steering technology; safety innovations; high-definition cameras; aerial views captured with specialized systems that compensate for movement during filming, resulting in stable and smooth footage footage; and much quieter rides thanks to relocated engines and propellers.There currently are four Goodyear Blimps — the three in the U.S. and one in Friedrichshafen, Germany.
