$2,100 mechanical keyboard has 800 holes, NYC skyscraper looks

What’s interesting about the typing feel of this keyboard is the use of low-profile keycaps despite the keyboard supporting full-height mechanical switches. I’m curious if the pairing results in the keycaps feeling too thin or unstable while typing. Other Icebreaker specs include a “silicone dampener integrated into the bottom lid both supporting the PCB and […]

Do black holes really evaporate — and how do we know?

In 1974, Stephen Hawking put forward an intriguing idea: Using the principles of quantum physics, he predicted that even though nothing is supposed to escape a black hole’s event horizonthese cosmic beasts can actually emit particles. And by ejecting these particles, black holes will shrink over a very long time, eventually evaporate and possibly explode. […]

Scientists followed a mysterious signal — and found 2 black holes gorging on something like never before

Supermassive black holes — cosmic titans with masses of 100,000 to billions of times the mass of the sun — are among the universe’s most fearsome phenomena. These celestial behemoths can consume entire stars and unleash torrents of powerful radiation visible across vast cosmic distances. However, in a recent study, researchers observed something entirely unprecedented: […]

New map of the universe uses gravitational waves to reveal hidden black holes and cosmic structure

Credit: Carl Knox, OzGrav, Swinburne University of Technology and South African Radio Astronomy Observatory (SARAO) An international study led by astronomers from Swinburne University of Technology has created the most detailed maps of gravitational waves across the universe to date. The study has also produced the largest ever galactic-scale gravitational wave detector and found further […]

The contentious genius who made black holes real

The Impossible Man: Roger Penrose and the Cost of Genius Patchen Barss Basic (2024) In the early days of a book project that would span six years, writer Patchen Barss had the best stroke of luck a biographer can hope for. His subject, the Nobel prizewinning mathematical physicist Roger Penrose, brought him a bundle of […]

The Mystery of How Supermassive Black Holes Merge

However, modeling has shown that it is difficult to scatter enough stars toward the black holes to solve the final-parsec problem. Alternatively, each black hole might have a small disk of gas around it, and these disks might draw in material from a wider disk that surrounds the empty region carved out by the holes. […]

Necrotizing fasciitis: The ‘flesh-eating’ infection that bores holes in the body

Disease name: Necrotizing fasciitis, also known as “flesh-eating disease” Affected populations: Flesh-eating disease can affect anyone. It occurs in about 0.4 in 100,000 people in the U.S. each year. The disease is most commonly seen in people with conditions that weaken the immune systemsuch as cancer, liver scarring (cirrhosis), diabetes and kidney disease. Causes: Necrotizing […]

‘Webb has shown us they are clearly wrong’: How astrophysicist Sophie Koudami’s research on supermassive black holes is rewriting the history of our universe

A supermassive mystery lurks at the center of the Milky Way. Supermassive black holes are gigantic ruptures in space-time that sit in the middle of many galaxies, periodically sucking in matter before spitting it out at near light speeds to shape how galaxies evolve. Yet how they came to be so enormous is a prevailing […]

‘Hawking radiation’ may be erasing black holes. Watching it happen could reveal new physics.

Primordial black holes (PBHs), which are thought to have formed right after the Big Bang, may be heating up and exploding throughout the universe. These black hole explosions, powered by Hawking radiation — a quantum process where black holes generate particles from the vacuum due to their intense gravitational fields — could be detected by […]
