A strange ripple in spacetime could be the first fingerprint of dark matter
3+ hour, 32+ min ago (887+ words) Dark matter is believed to make up most of the matter in the universe, yet scientists still cannot observe it directly. Unlike ordinary matter, dark matter does not interact with light or electromagnetic forces, making gravity the only known way…...
NASA shared the audio from a black hole showing what it actually sounds like and people are saying it's really creepy
5+ hour, 47+ min ago (386+ words) Have you ever wondered what a black hole would sound like if humans could actually hear it, well thanks to NASA, we know now. The space agency shared an eerie audio clip from deep space, and the internet quickly became…...
String theory suddenly emerged from simple physics rules
3+ hour, 41+ min ago (906+ words) String theory offers a potential way around that problem. In the theory, every particle, including the hypothetical graviton that would carry the force of gravity, comes from different vibrations of tiny strings. The mathematics also requires the strings to exist…...
The supermassive black hole at the centre of the Milky Way has a mass of 4 million suns, and the entire solar system is orbiting it at 514, 000 mph without anyone on Earth feeling a thing
9+ hour, 8+ min ago (671+ words) The galactic center sits 26, 000 light-years away, and the orbital mechanics binding Earth to a four-million-solar-mass object reveal more about how gravity actually works than the headline number ever does....
A "portal" to another dimension? How a theoretical particle could solve the dark matter mystery
13+ hour, 44+ min ago (395+ words) Adrian Carmona from Spain's University of Granada wrote the paper alongside Javier Castellano Ruiz and Matthias Neubert from Johannes Gutenberg University in Germany. They published their framework in the European Physical Journal C. Their model resolves the dark matter problem by…...
End of the Universe? Chinese researchers create super-bubble in lab that could destroy
18+ hour, 53+ min ago (349+ words) Scientists at Tsinghua University have recreated a frightening cosmic event in a laboratory that, in theory, could destroy the entire universe in an instant. Researchers successfully observed the main process behind a theory known as 'false vacuum decay'. The results…...
Scientists detect mysterious blue flashes erupting from deep space 'unlike anything seen before"
11+ hour ago (529+ words) Only 14 have ever been recorded Since the first one lit up astronomers' telescopes in 2018, only 14 Luminous Fast Blue Optical Transients (LFBOTs) have ever been recorded. They burn up to 100 times brighter than any other known stellar explosion, displaying an intense…...
Earth's magnetic field could be 'ringing' with dark matter " Physics World
16+ hour, 31+ min ago (557+ words) Sabnam Shrestha is a Ph D student contributor to Physics World. She is currently pursuing her graduate studies in physics at the University of Alabama, Tuscaloosa, US. She is interested in active galactic nuclei, with emphasis on their role in…...
What If the Universe Had No Beginning? Part 3: A Universe From Nothing
3+ day, 17+ hour ago (79+ words) Run Hawking's machinery and out pops something startling: the most likely universe looks an awful lot like ours, complete with inflation, a low-entropy beginning, and an arrow of time. All of cosmology, falling out for free. Almost....
