Can a theory that isn’t completely testable still be useful to physics? What determines if an idea is legitimately scientific or not? This question has been debated by philosophers and historians of science, working scientists, and lawyers in courts of law. That’s because it’s not merely an abstract notion: What makes something scientific or not determines if it should be taught in classrooms or supported by government grant money.
Scientists think that, under some circumstances, dark matter could generate powerful enough gravitational waves for equipment like LIGO to detect. Now that observatories have begun to record gravitational waves on a regular basis, scientists are discussing how dark matter—only known so far to interact with other matter only through gravity—might create these gravitational waves.
From Windy City Live, April 17, 2019: Romanieo Golphin Jr. is a global scientific ambassador to CERN, and he’s only nine years old! He stopped by the Windy City Live Science Lab to share some of his favorite science experiments and mentions his visit to Fermilab in this 9-minute video.
From The Beacon-News, April 18, 2019: The 12th annual STEM Career Expo at Fermilab allowed high school students interested in careers in math and science to interact with scientists at the lab and other professionals. More than 30 local companies and research organizations were represented at the event.
One of the latest discoveries from the LHC takes the properties of photons beyond what your electrodynamics teacher will tell you in class. For most of the year, the LHC collides protons, but for about a month each fall, the LHC switches things up and collides heavy atomic nuclei, such as lead ions. The main purpose of these lead collisions is to study a hot and dense subatomic fluid called the quark-gluon plasma, which is harder to create in collisions of protons. But these ion runs also enable scientists to turn the LHC into a new type of machine: a photon-photon collider.
From the Kane County Chronicle, April 11, 2019: High school students who are potentially interested in a career in the STEM fields are invited to learn more about opportunities at the Fermilab STEM Career Expo from 5:30 to 8:30 p.m. April 17 at in the atrium of Fermilab’s Wilson Hall. Students will meet with STEM professionals and ask questions about STEM careers. In addition to Fermilab scientists and engineers, the STEM Career Expo will feature more than 100 professionals from more than 30 local companies and research organizations who will explain what they do.
From ABC7: Fermilab scientist Brad Benson talks about the South Pole Telescope’s role part in the Event Horizon Telescope. Scientists behind the Event Horizon Telescope recently revealed the first image ever made of a black hole, depicting its hot, shadowy edges where light bends around itself in a cosmic funhouse effect. Assembling data gathered by eight radio telescopes around the world, astronomers created the picture showing the violent neighborhood around a supermassive black hole, the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades.
From WBEZ’s Morning Shift, April 10, 2019: WBEZ interviews Fermilab scientist Brad Benson about the recent unveiling of the first ever photograph of a black hole. The Event Horizon Telescope, a collaboration between more than 200 scientists using telescopes from around the world, shot photographs of a supermassive black hole in the galaxy M87.
A re-examination of a particle discovered in 2015 has scientists debating its true identity. A recent analysis by the LHCb collaboration at CERN raises questions about the identity of this pentaquark—and may have taken scientists back to square one in the search for a particle that could shed light on questions about color.
From CERN, March 19, 2019: DUNE co-spokesperson Stefan Soldner-Rembold talks the international Deep Underground Neutrino Experiment hosted at Fermilab, neutrinos and the global particle physics community’s efforts to understand this subtle particle.
