Angelo Bassi and Stephen Adler
“I always considered it rather an empty game. Physics is an experimental subject. If they can’t be distinguished experimentally, I don’t care what your interpretation is.” Stephen L. Adler , Professor Emeritus in the School of Natural Sciences, is quoted in this New York...
In a new study of axion motion, researchers propose a scenario known as “kinetic misalignment” that greatly strengthens the case for axion/dark matter equivalence. The novel concept answers key questions related to the origins of dark matter and provides new avenues for ongoing detection efforts...
Freeman Dyson at IAS
Robbert Dijkgraaf, IAS Director and Leon Levy Professor, remembers Freeman J. Dyson, the legendary physicist, writer, and fearless intellectual explorer who served on the Faculty in the School of Natural Sciences at the Institute for over 65 years. “As an eternal graduate student, a ‘rebel’ in his own words, Dyson was unafraid to question everything and everybody," writes Dijkgraaf in the PNAS . “… Perhaps he understood better than most that progress stems from disagreement more than agreement.”

Occupying a region of space (L2) four times more distant than the moon, the SRG observatory is busily rendering an X-ray map of the universe and has officially reached the half-way mark of its first all-sky survey, which began in December and is...
Last April, the Event Horizon Telescope (EHT) sparked international excitement when it unveiled the first image of a black hole. Today, a team of researchers have published new calculations that predict a striking and intricate substructure within black hole images from extreme gravitational light bending...
A new study, conducted to better understand the origin of the universe, has provided insight into some of the most enduring questions in fundamental physics: How can the Standard Model of particle physics be extended to explain the cosmological excess of matter over antimatter? What...
Freeman J. Dyson , theoretical physicist and writer, who embraced the stunning diversity of the universe with unique spirit, died on February 28, 2020 in a hospital near Princeton, NJ at the age of 96. Dyson generated revolutionary scientific insights, including calculations bridging the...
James Stone and Scott Tremaine
James Stone , Professor in the School of Natural Sciences, and Scott Tremaine , Richard Black Professor in the School, have been named Fellows of the American Astronomical Society (AAS). This new accolade honors AAS members for extraordinary achievement and service. Fellows are...
Scott Tremaine
Scott Tremaine , Richard Black Professor in the School of Natural Sciences, has been awarded the 2020 Henry Norris Russell Lectureship from the American Astronomical Society. Selected annually, the Russell Lecturer is chosen on the basis of a lifetime of eminence in astronomical research...
Illustration by Robbert Dijkgraaf
The artwork by Robbert Dijkgraaf , Director and Leon Levy Professor, depicts Russian nesting to capture the different scales of knowledge about the natural world, from the largest matryoshka doll that depicts our universe through the cosmic microwave background, the “first light” emitted soon after the Big Bang, to the smallest doll, the Planck scale, where spacetime becomes a quantum phenomenon.
