String theory

A lab-made black hole is beyond current technology but could be possible one day

The Ads/CFT duality conjecture suggests our universe is a hologram, enabling significant discoveries in the 25 years since it was first proposed

His groundbreaking work combined the mathematical field of topology with string theory

Runaway success and underfunding have led to growing pains for the preprint server

The Harvard physicist explains the collaboration's long-awaited research on the black-hole information paradox

In my last post Steven Weinberg, one of history’s greatest physicists, answers questions about progress—or the lack thereof—in particle physics, cosmology and politics.

One might think that success in science requires seeing through your own bullshit as well as the bullshit of others. But in my experience, this quality is quite rare.

Last night at the 87th Academy Awards, Eddie Redmayne won the Oscar for best actor for his portrayal of theoretical physicist and cosmologist Stephen Hawking in The Theory of Everything.

In 2007 Garrett Lisi was a 39-year-old physicist, unaffiliated with any institution, toiling in obscurity on what he called "An Exceptionally Simple Theory of Everything,” which could account for all of nature’s forces.

At a 1990 conference on cosmology, I asked attendees, who included folks like Stephen Hawking, Michael Turner, James Peebles, Alan Guth and Andrei Linde, to nominate the smartest living physicist.

I exaggerate with the title of this post, but only slightly. The title is a reaction to a strange article on multiple universes written by Tom Siegfried at Science News.

Leonard Susskind rebelled as a teen and never stopped. Today he insists that reality may forever be beyond reach of our understanding
