Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.
Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.
An experiment conducted on hybrid matter-antimatter atoms has defied researchers’ expectations.
Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed.
Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff.
When astronomers tried to confirm a signal from the birth of the first stars after the Big Bang, they saw nothing.
Celia Escamilla-Rivera is combining large data sets with supercomputers to test general relativity against its little-known competitors.
The strong force holds protons and neutrons together, but the theory behind it is largely inscrutable. Two new approaches show how it works.
