If you have ever wondered what it might feel like to be sucked into a black hole — twisted, stretched, confused, doomed — you could do worse than trip through “The Warped Side of Our Universe, An Odyssey Through Black Holes, Wormholes, Time Travel and Gravitational Waves,” a collaborative book project by Kip Thorne, a physicist at the California Institute of Technology, and Lia Halloran, a visual artist and chair of the art department at Chapman University in Orange, Calif.Dr. Thorne brings impressive credentials to the task. In 2017 he won the Nobel Prize in Physics for his work on the Laser Interferometry Gravitational-Wave Observatory, or LIGO, which discovered space-time vibrations resulting from the collision of two distant black holes. He was also the executive producer of the movie “Interstellar.” Ms. Halloran, who grew up surfing and skateboarding in the Bay Area, became obsessed with science after a high school internship at the Exploratorium in San Francisco. The book consists of illustrations of what Dr. Thorne likes to call the “space-time storms” predicted by general relativity, Einstein’s theory of gravity, alternating with his own explanations of the physics, which appear in verse. Many of the illustrations, which are in ink on drafting film, portray Ms. Halloran’s wife, Felicia, being whipped around, crushed and twisted by the forces of nature.

Those ripples are probably the distant thunder of countless collisions between supermassive black holes, throughout space and time. He predicted that the intense gravity of extremely massive objects, like black holes, warps the fabric of space-time. The NSF funded the 15-year experiment, which is called the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). Supermassive black holes are thought to exist at the center of every galaxy. Her lab runs computer models of merging supermassive black holes to predict how they behave and what signals they send out into space.

Fenomenul a fost observat în 2019 cu ajutorul undelor gravitaţionale. În 2019, observatoarele de unde gravitaţionale LIGO şi Virgo au fost folosite pentru a identifica, în premieră, un sistem binar, format dintr-o gaură neagră şi o stea neutronică care s-au ciocnit, notează Science Alert. Într-o lucrare care urmează să treacă prin procesul de peer review, cercetătorii din cadrul colaborării ENGRAVE (ElectromagNetic counterparts of GRAvitational wave sources at the VEry Large Telescope) explică faptul că această coliziune, în mod straniu, nu o anume urmare. Oamenii de ştiinţă explică faptul că radiaţia electromagentică este omologul valurilor gravitaţionale. Studiul a fost publicat pe serverul arXiv şi urmează să fie publicat în Astronomy & Astrophysics.
