His incompleteness theorems destroyed the search for a mathematical theory of everything. Nearly a century later, we’re still coming to grips with the consequences.
Astronomers are discovering that magnetic fields permeate much of the cosmos. If these fields date back to the Big Bang, they could solve a major cosmological mystery.
Researchers say there are three possible explanations for the anomalous data. One is mundane. Two would revolutionize physics.
We asked four physicists why gravity stands out among the forces of nature. We got four different answers.
By chewing on the problems posed by “extremal” black holes, physicists have exposed a surprising and universal connection between energy and entropy.
The first official evidence of a key imbalance between neutrinos and antineutrinos provides one of the best clues for why the universe contains something rather than nothing.
The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.
Sometimes a mirror that reflects 99.9999% of light isn’t good enough.
In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty.
