Gravitational Waves Should Permanently Distort Space-Time
...Thorne, a physicist at the California Institute of Technology whose work on gravitational waves earned him part of the 2017 Nobel Prize in Physics. “It is connected ultimately to the...
Black Hole Firewalls Could Be Too Tepid to Burn
...stuff,” said Donald Marolf, a physicist at the University of California, Santa Barbara, and one of the four co-authors. The argument caused an uproar in the theoretical physics community, much...
How Maxwell’s Demon Continues to Startle Scientists
The thorny thought experiment has been turned into a real experiment — one that physicists use to probe the physics of information. The universe bets on disorder. Imagine, for example,...
Sun’s Puzzling Plasma Recreated in a Laboratory
...in Nature Physics. The experiment was also able to mimic a region around the sun where the plasma hangs in a precarious balance. Within this boundary, plasmas are contained by...
This Physicist Discovered an Escape From Hawking’s Black Hole Paradox
...— then seemed to be permanently lost. Hawking’s calculation posed a paradox — the infamous “black hole information paradox” — that has motivated research in fundamental physics ever since. On...
Black Hole Echoes Would Reveal Break With Einstein’s Theory
...in theoretical physics. We dream of the day when one of our equations will be plotted against data and fit spot on. It’s rare for this dream to come true....
Squishy Neutron Star Setback Dampens Hopes of Exotic Matter
...Born from supernovas, these objects contain a star-size mass in a city-size space. This unique trait has led scientists to believe that some extreme physics might take place in their...
In Violation of Einstein, Black Holes Might Have ‘Hair’
...the Institute for Advanced Study in Princeton, New Jersey. That paradox distills the fundamental conflict between general relativity and quantum mechanics, the two great pillars of 20th-century physics. “If you...
Why the Tiny Weight of Empty Space Is Such a Huge Mystery
...physics, has to say about empty space. A quantum field is empty when there are no particle excitations rippling through it. But because of the uncertainty principle in quantum physics,...
