Dark matter is a substance that has gravity—it holds galaxies together—but cannot be directly seen with any instrument yet created. Scientists are trying many different approaches to find the nature of this mysterious substance.

Kamionkowski is known for his early work on the possibility that dark matter could be composed of elementary particles and his more recent work on the hypothesis of dark matter being made up of black holes.

Congratulations to Vincenzo Vitelli and Carlos E.M. Wagner, who were named 2025 fellows of the American Association for the Advancement of Science for their distinguished contributions to the sciences. 

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

In this spring’s Compton Lectures, Keith McBride, a UChicago postdoctoral researcher, will illuminate how astroparticles can answer questions about the farthest reaches of our universe as well as be harnessed as practical tools to understand our earth. The free public talks run every Saturday from March 28 through May 16 at 11 AM.

Bonnie Fleming has joined UChicago as professor of physics, effective March 10. Previously, Fleming served as Fermilab’s Deputy Director for Science and Technology and Chief Research Officer and a part-time University of Chicago faculty member with appointments in the Physics Department and the Enrico Fermi Institute. Read a Q&A with our newest full-time physics professor.

The University of Chicago Library exhibit "Binding Energy: Books by Chicago Physics Faculty" explores the work of researchers from Enrico Fermi to the only woman on the Pile-1 team.

New infrared light sources mark 100-fold efficiency boost, could improve broad range of sensors, technology.

Congratulations to early-career scholars Aloni Cohen (Computer Science and DSI), Anna Wuttig (Chemistry), and Zoe Yan (Physics), recognized for their potential to make substantial contributions to their fields.
