Moonshine Link Discovered for Pariah Symmetries
...symmetry groups to special classes of “weight 3/2” modular forms, objects that also show up in natural counting functions for black holes and for higher-dimensional generalizations of strings called “branes.”...
Ultra-Powerful Radio Bursts May Be Getting a Cosmic Boost
...What could possibly be making such blasts? Astrophysicists imagined one-off cataclysms — perhaps collapsing stars, or colliding black holes — which would seem to be the only way to generate...
Troubled Times for Alternatives to Einstein’s Theory of Gravity
...principle, which states that very dense strong-gravity objects such as neutron stars or black holes “fall” in the same way when placed in a gravitational field. (On Earth, the more...
A Short History of the Missing Universe
...quasars — the bright cores of galaxies with active black holes at their center — using the new spectrograph at the Keck telescope in Hawaii. Tytler’s data helped researchers understand...
New Quantum Paradox Clarifies Where Our Views of Reality Go Wrong
...of humans and even lesser, [whether] it extends to objects the size of black holes.” Despite this lack of empirical evidence, physicists think that quantum mechanics can be used to...
The Astronomer Who’d Rather Build Space Cameras
...to be luminous material surrounding supermassive black holes.) So in the ’70s, you built one of the earliest astronomical instruments with CCDs, which had just been invented and could detect...
Solution: ‘Perfect Randomness’
...the Einstein-Rosen (ER) bridge. This was originally proposed in the context of black holes, but perhaps it is true for all entangled particles, as I have discussed in a previous...
Virginia Trimble Has Seen the Stars
...a paper with recent Nobel Prize winner Kip Thorne on the search for black holes and neutron stars. But for David DeVorkin, the senior curator of history of astronomy at...
Why I’m Hosting The Joy of x Podcast
...taught me a lot. As you’ll hear in one episode, the astrophysicist Janna Levin schooled me about black holes, but what I found even more delightful was her explanation of...
