No, the James Webb Space Telescope Hasn’t Broken Cosmology

February 27, 2023

The Webb telescope has spotted galaxies surprisingly far away in space and deep in the past. These four, studied by a team called JADES, are all seen as they appeared less than 500 million years after the Big Bang.

Prof. Wendy Freedman is exploring how JWST observations can be squared with the standard cosmological model.

Deep earthquakes could reveal secrets of the Earth’s mantle

February 22, 2023

Earth sliced in half, showing the different layers of the planet inside.

A new study led by University of Chicago geophysicist Sunyoung Park suggests there may be a layer of surprisingly fluid rock located in the Earth’s mantle. The study uses 350-mile-deep earthquake to make elusive measurements of the Earth’s layers.

Dark energy from supermassive black holes? Physicists spar over radical idea

February 17, 2023

An artist's impression of a supermassive black hole in the center of a galaxy.

Earlier this week, a study made headlines claiming that the mysterious “dark energy” cosmologists believe is accelerating the expansion of the universe could arise from supermassive black holes at the hearts of galaxies. If true, the connection would link two of the most mind-bending concepts in physics—black holes and dark energy—and suggest that the source of the latter has been under theorists’ noses for decades. However, some leading theorists are deeply skeptical of the idea.
