Tech & ScienceAstronomers have spotted huge swaths of gas spinning around the supermassive black hole thought to sit at the heart of the Milky Way.The rambunctious clouds—observed moving at almost one-third of the speed of light—are a “resounding confirmation” of scientists’ long-standing belief in the galactic behemoth known as Sagittarius A*, researchers said in a statement released by the European Southern Observatory (ESO).Black holes are regions of space where gravity is so intense it gulps up everything from matter to light that strays too close. As a result, the holes themselves are completely dark and incredibly cold. But nearby orbiting matter gets fiercely hot and bright as it races around the massive objects.Astronomers using the ESO’s GRAVITY instrument on the Very Large Telescope in Chile spied some of the material charging around Sagittarius A*. Flares of infrared radiation alerted scientists to the gas swirling near the … [Read more...] about Massive Clouds of Gas Hurtle Around Our Galaxy’s Black Hole at One-third the Speed of Light

An image of the cosmic microwave background Credit: ESA and the Planck Collaboration We are not living in the first universe. There were other universes, in other eons, before ours, a group of physicists has said. Like ours, these universes were full of black holes. And we can detect traces of those long-dead black holes in the cosmic microwave background (CMB) — the radioactive remnant of our universe's violent birth. At least, that's the somewhat eccentric view of the group of theorists, including the prominent Oxford University mathematical physicist Roger Penrose (also an important Stephen Hawking collaborator). Penrose and his acolytes argue for a modified version of the Big Bang. In Penrose and similarly-inclined physicists' history of space and time (which they call conformal cyclic cosmology, or CCC), universes bubble up, expand and die in sequence, with black holes from each leaving traces in the universes that follow. And in a new paper … [Read more...] about Physicists think they’ve spotted the ghosts of black holes from another universe
Tech & Science A Virgin Galactic rocket launched its commercial spacecraft and the two pilots aboard more than 30 miles into the atmosphere above the Mojave Desert at almost two-and-a-half times the speed of sound. The VSS Unity’s third launch marked the first time a Virgin Galactic spaceship entered the mesosphere, a middle layer of Earth’s atmosphere 30 to 50 miles above its surface, an altitude too high for commercial aircraft and weather balloons to reach. Company heads hope the successful test proves its first round of space tours isn’t too far off. The “space plane,” propelled by rockets for more than 40 seconds to achieve a speed of Mach 2.47, reached its fastest speed and traveled more than 170,800 feet in the atmosphere. The next step, Virgin engineers said, is to cross the Karman Line, 62 miles above the Earth’s sea level, which is commonly considered the point where the atmosphere ends and space begins. But the VSS Unity might have … [Read more...] about Virgin Galactic Space Plane Travels Twice the Speed of Light, Commercial Flights Next?
Sections Skip to content Skip to site index Five decades after her first restaurant in Paris, she has retreated from the dining room but remains a fast-moving force, worrying every detail. Maguy Le Coze at Le Bernardin, the Midtown Manhattan citadel of seafood that she owns with the chef Eric Ripert. Mr. Ripert called her “the soul, the spirit and the boss” of the restaurant. Credit Damon Winter/The New York Times Supported by ByAlan Richman June 5, 2018 She grew up in a modest hotel run by her parents in a French seaport village, sharing a room with her younger brother. Her father cooked, her mother oversaw the dining room, and Maguy Le Coze was waiting tables by the time she was 12, a serious child who forever remained that way. The two children attended separate elementary schools in Port Navalo — Gilbert the one for boys, Maguy the one for girls. There was another difference: “I would do my homework,” she said. … [Read more...] about Still the Boss of Le Bernardin, Maguy Le Coze Strides On
Bryan Logan, provided by Published 7:41 pm, Monday, May 14, 2018 The driver of a Tesla Model S that collided with a fire department vehicle in Utah last week reportedly told police that she had Autopilot engaged at the time of the crash. The South Jordan Police Department told news outlets on Monday that the driver, a 28-year-old woman, had been looking at her phone before the crash, during which the Tesla was traveling at highway speeds. Tesla says it is cooperating with the investigation. This is the latest in a series of Tesla crashes in recent months involving the company's semi-autonomous driving Autopilot feature. The vehicle was traveling at highway speed, and according to the Associated Press, it had not slowed down before the collision. The driver suffered a broken ankle. Tesla says it is cooperating with the South Jordan Police Department in Utah in the ongoing investigation. "Tesla has not yet received any data from the car and thus does not know the facts of what … [Read more...] about Tesla Model S driver who collided with a fire department vehicle in Utah says Autopilot was engaged at the time of the crash (TSLA)
