The detailed mechanics of how matter falls down onto a black hole from outside the event horizon have been revealed in a new paper. As predicted by Einstein’s theory of gravity, there’s a point at which material stops circling the black hole and falls straight down, plunging precipitously beyond the point of no return. Now, […]

Black holes are mysterious, yet also deceptively simple − a new space mission may help physicists answer hairy questions about these astronomical objects
Physicists consider black holes one of the most mysterious objects that exist. Ironically, they’re also considered one of the simplest. For years, physicists like me have been looking to prove that black holes are more complex than they seem. And a newly approved European space mission called LISA will help us with this hunt. Research […]
Physicists Say They May Have Found a Powerful Glitch in the Universe
Einstein 2.0 Researchers have discovered what they’re calling a “cosmic glitch” in gravity, which could potentially help explain the universe’s strange behavior on a cosmic scale. As detailed in a new paper published in the Journal of Cosmology and Astroparticle Physics, the team from the University of Waterloo and the University of British Columbia in Canada posit […]
Physicists Have Unraveled the Surprisingly Hot Mystery of Sand in an Hourglass
“Hearst Magazines and Yahoo may earn commission or revenue on some items through these links.” To model how sand jams in an hourglass, physicists combine two gridlike math models. Flowing sand is vulnerable to jamming, including a jamming transition that could be disrupted. Granules and the subset of powders have their own entire area of […]
