This Cosmologist Knows How It’s All Going to End
...eventually star formation halts, because there’s no new material being brought in. The stars you have burn out. A lot of things fall into black holes, then the black holes...
Joe Polchinski’s Restless Pursuit of Quantum Gravity
...a paradox about the nature of black holes. The “firewall argument,” as it’s called — developed with Ahmed Almheiri, Donald Marolf and James Sully — “took form over three months...
A Hint of Dark Matter Sends Physicists Looking to the Skies
...from undiscovered particles to black holes. One idea in particular, however, is drawing renewed attention: the axion. And researchers are turning to the skies to track it down. Axions are...
For Astronomers, Neutron Star Merger Could Eclipse Eclipse
...it had detected gravitational waves from two colliding black holes. Four months later, while still in its first observing run, the team confirmed the detection of a second black hole...
The End of Theoretical Physics as We Know It
...no one can calculate how they come together to make a proton. The equations just can’t be solved by any known methods. Similarly, a merger of black holes or even...
The Physicist Who Slayed Gravity’s Ghosts
...find amazing about general relativity is that it tells you precisely when it stops working. Out of the laws of general relativity come black holes. From the outside, we think...
Random Surfaces Hide an Intricate Order
...Next, fit them together in any fashion, as long as the final shape closes up like wrapping paper around a gift (so no holes or openings). If you start with...
Quanta Writers and Editors Discuss Trends in Science and Math
...especially the role of black holes in the universe. But I would say, actually, what excites me most is that in this period of — kind of — turmoil and...
New Studies Rescue Gravitational-Wave Signal From the Noise
...their criticism on the experiment’s famous first signal, a squiggly line — representing the collision of giant black holes more than a billion light-years away — that was printed in...
