A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

As technology improves, scientists discover new ways to search for theorized dark matter particles called axions. In the early 1970s, physics had a symmetry problem. According to the Standard Model, ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.

The fundamental particle of light is both ordinary and full of surprises. What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

Three physicists share their experiences learning and communicating physics in a foreign language: English. Rose Ferreira, an astronomer and popular-science communicator who goes by the name Rose DF, ...

Rubin Observatory will bring new capabilities to the studies of dark matter and dark energy. In just a few years, scientists at Vera C. Rubin Observatory in Chile will launch the Legacy Survey of ...

Matter and antimatter behave differently. Scientists hope that investigating how might someday explain why we exist. One of the great puzzles for scientists is why there is more matter than antimatter ...

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size. At least when it comes to particle accelerators, bigger is ...

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it. The Large Synoptic Survey Telescope, a flagship astronomy and astrophysics ...

Just over 40 years ago, a new theory about the early universe provided a way to tackle multiple cosmological conundrums at once. For Alan Guth, insight into the origins of the universe started in a ...
