Unexpected #JWST Observations Hint We Might Be Inside A #BlackHole
A new study looking at observations by the JWST of the early universe has thrown up a new and intriguing mystery; the majority of #galaxies appear to be rotating in the same direction. This finding, not predicted by our current understanding of the universe, may hint that we are inside a black hole, according to the study's authors.

Evidence for #StephenHawking's unproven #blackhole theory may have just been found — at the bottom of the sea
The recent discovery of a stupendously powerful #neutrino has left scientists scratching their heads. New research suggests it could be evidence that Stephen Hawking was right about the nature of #blackholes and the early #universe.

Discovery of extreme Quasi-Periodic Eruptions in a newly accreting massive #BlackHole: arxiv.org/abs/2504.07169 -> X-treme X-rays in an X-tra young system: astrobites.org/2025/04/16/x-tr

arXiv.orgDiscovery of extreme Quasi-Periodic Eruptions in a newly accreting massive black holeQuasi-periodic eruptions (QPEs) are rapid, recurring X-ray bursts from supermassive black holes, believed to result from interactions between accretion disks and surrounding matter. The galaxy SDSS1335+0728, previously stable for two decades, exhibited an increase in optical brightness in December 2019, followed by persistent Active Galactic Nucleus (AGN)-like variability for 5 years, suggesting the activation of a $\sim$10$^6\;M_\odot$ black hole. From February 2024, X-ray emission has been detected, revealing extreme $\sim$4.5-day QPEs with the highest fluxes and amplitudes, longest time scales, largest integrated energies, and a $\sim$25-day super-period. Low-significance UV variations are reported for the first time in a QPE host, likely related to the long timescales and large radii from which the emission originates. This discovery broadens the possible formation channels for QPEs, suggesting they are not linked solely to tidal disruption events but more generally to newly formed accretion flows, which we are witnessing in real time in a turn-on AGN candidate.

Six years since ALMA crucially helped the Event Horizon Telescope take the first image of a supermassive black hole in a distant galaxy… you can relive it all below!

www.almaobservatory.orgAstronomers Capture the First Image of a Black Hole | ALMA ObservatoryPress Conference Streaming The Event Horizon Telescope (EHT), a planet-scale array of eight ground-based radio telescopes forged through international collaboration, was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole...

Risale al 10 aprile 2019 la prima foto di un buco nero.
Generati dal collasso gravitazionale di una stella morente, sono oggetti cosmici in grado di deformare lo #spaziotempo.
Così Laurence #Sterne e Denis #Diderot manipolano lo #spazio e il #tempo nelle opere proposte in questo articolo di #Itinera.
Testi che sono contemporaneamente completi e incompleti, così come il gatto di #Schrodinger è contemporaneamente vivo e morto.
