Everything that humans have seen up until now exists in the 4.9 per cent of the universe that interacts with light. The rest is hidden from view. Most of it, physicists believe—68.3 per cent—is dark energy, an enigmatic force that drives the...

The 2017 Prospects in Theoretical Physics program will celebrate its sixteenth year by convening more than 130 graduate students and postdoctoral scholars from around the world at the Institute for Advanced Study from July 17 to 28 to explore...

“What is space and time really? Why is the universe really big?” Professor Nima Arkani-Hamed asks. “And on top of that, we don’t understand why there are big things in it.”

Part of a family that zigzagged the globe in pursuit, and defense, of science...

Professor Nima Arkani-Hamed is among those newly elected.

How does science work? . . . The scientific method—famously objective, logical and eminently reliable; and the fruits of its success, both pure and applied, are the single most obvious factor in distinguishing the varying levels of progress between...

In the 1960s, the charismatic physicist Geoffrey Chew, Member (1956) in the School of Mathematics/Natural Sciences, espoused a radical vision of the universe, and with it, a new way of doing physics, arguing that "Nature is as it is because this is...

String theory has so far failed to live up to its promise as a way to unite gravity and quantum mechanics, but at the same time, it has blossomed into one of the most useful sets of tools in science. 

Lectures by Nima Arkani-Hamed, Robbert Dijkgraaf, Nathan Seiberg, Juan Maldacena, Edward Witten, and Institute Members from the 2016 Strings conference.

The story of how and why the universe began is written in the sky. Cosmologists believe that details of the Big Bang are encoded in triangles and other shapes that appear in the distribution of galaxies. Lately, they’ve made significant progress in...
