Black Hole

Home News Science & Astronomy Astronomers have photographed a violent cosmic dance that began between two galaxies a billion years ago, pulling them into a collision that birthed a new chaotic galaxy.  At the heart of that giant collision-born galaxy are two supermassive black holes — each once at the…

Black holes, wormholes, entanglement, Einstein, mysterious islands and new science that sees how the inside of a black hole is secretly on the outside. Black holes have been a big problem in physics. For decades, scientists have been mystified about what happens to stuff that falls into a black hole. …

Recent theoretical and observational results have revealed new secrets about these shadowy objects, with deep implications for more than just black holes themselves By Clara Moskowitz By:Clara Moskowitz close Clara Moskowitzis Scientific American's senior editor covering space and physics. She has a bachelor's degree in astronomy and physics from Wesleyan…

These fun stories show progress from the scale of quantum effects to that of snakes and from Earth to the edge of the universe Credit: Scientific American, August 2022 If somebody yells, “Snake!” are you more likely to jump back in fright or say, “Ooh, where?” Fear of snakes (ophidiophobia)…

ESO’s Very Large Telescope (VLT) has imaged the result of a spectacular cosmic collision — the galaxy NGC 7727. This giant was born from the merger of two galaxies, an event that started around a billion years ago. At its centre lies the closest pair of supermassive black holes ever…

SAN JOSE, Costa Rica —  On Father’s Day last year, Octavio Enríquez shared pizza and soda with his two children. Then he told them he was leaving. A Nicaraguan journalist known for rigorous investigations, his latest reporting had led him dangerously close to President Daniel Ortega, a former leftist revolutionary who…

Blazars are powerful active galactic nuclei in which supermassive black holes eject relativistic jets directed along our line of sight. A blazar can shine brighter than its galaxy and can be seen with radio telescopes from a distance of billions of light-years away. Scientists at the Event Horizon Telescope (EHT)…

From the exceedingly big to the unfathomably small, cosmologists are trying to unravel a bizarre set of figures that may reveal what happens inside a black hole, why the Higgs boson is so light and the chances of you having a doppelgänger Physics 9 August 2022 By Antonio Padilla Christian…

mathematical physicsBy Steve NadisAugust 4, 2022 The solutions to Einstein’s equations that describe a spinning black hole won’t blow up, even when poked or prodded. Mehau Kulyk / Science Source In 1963, the mathematician Roy Kerr found a solution to Einstein’s equations that precisely described the space-time outside what we…
