The Double Life of Black Holes
Perfect black holes are versatile mathematical tools. Just don’t mistake them for the real thing.
The End of Theoretical Physics as We Know It
Computer simulations and custom-built quantum analogues are changing what it means to search for the laws of nature.
Black Hole Echoes Would Reveal Break With Einstein’s Theory
Gravitational waves have opened up new ways to test the properties of black holes — and Einstein’s theory of gravity along with them.
Why an Old Theory of Everything Is Gaining New Life
For decades, physicists have struggled to create a quantum theory of gravity. Now an approach that dates to the 1970s is attracting newfound attention.
String Theory Meets Loop Quantum Gravity
Two leading candidates for a “theory of everything,” long thought to be incompatible, may be two sides of the same coin.
