Modeling black holes is easier with a flicker of light

A few days ago, I wrote about non-singular black hole models, specifically one known as the Hayward model. Since its introduction in 2006, several variations of the Hayward model have been introduced, including a rotating model similar to the Kerr metric used to study the supermassive black holes we’ve observed directly. This raises an interesting […]

Chemists find clues to the origins of buckyballs in space

Far from Earth, in the vast expanses of space between stars, exists a treasure trove of carbon. There, in what scientists call the “interstellar medium,” you can find a wide range of organic molecules—from honeycomblike polycyclic aromatic hydrocarbons (PAHs) to spheres of carbon shaped like soccer balls.

Rapid brightening of interstellar comet 3I/ATLAS as it nears sun surprises scientists

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling scientists.

Parabolic flight experiment highlights flame dynamics in microgravity

Casting a swirling shadow, a glowing candle flame sways eerily before flaring up once more. As ghostly as it looks, this flame dance is not the result of any force—paranormal or otherwise—but rather the lack of one: gravity.

A mundane universe and the rarity of advanced civilizations

How could the principle of “radical mundanity” proposed by the Fermi paradox help explain why humans haven’t found evidence of extraterrestrial technological civilizations (ETCs)? This is what a recent study posted to the arXiv preprint server hopes to address as a lone researcher investigated the prospect of finding ETCs based on this principle. This study […]
