Early Life in Death Valley
Paul Knauth scrambled up a steep, rocky canyon in the Black Mountains of Death Valley National Park, sporting gloves and a walking stick to help navigate the sharp scree. The...
Betting on the Future of Quantum Gravity
...constitute black holes. Profound conceptual puzzles posed by black holes suggest that the true theory will demand a radical new perspective on the universe — one in which space and...
Physicists Eye Quantum-Gravity Interface
...gravitational fields. Quantum mechanics and general relativity dominate in disparate domains, and they seem to converge only in enormously dense, quantum-size black holes. In the laboratory, as the physicist Freeman...
A Jewel at the Heart of Quantum Physics
...quantum field theory enters crisis mode in black holes. Black holes pack a huge amount of mass into an extremely small space, making gravity a major player at the quantum...
The Surprising Origins of Life’s Complexity
...comparing the ring in fungi to the ring in animals, the researchers have reconstructed its evolution. The ancestral ring had two types of protein. The black squares, triangles and circles...
Signs of a Stranger, Deeper Side to Nature’s Building Blocks
...of a lattice into the structure of the corresponding black hole by giving it a corrugated outer surface, or horizon. “When it comes to playing ball with black holes, you...
Peering Into the Early Universe
...time when the first stars and chemical elements and black holes and other exotica came into existence for the first time,” said Gerry Gilmore, an astronomer at Cambridge University. The...
Alice and Bob Meet the Wall of Fire
...Hawking realized that black holes aren’t completely black. While nothing might seem amiss to Alice as she crosses the event horizon, from Bob’s perspective, the horizon would appear to be...
