Scientists have long grappled with a fundamental question: what exactly is light?Is it a wave, flowing like ripples across water, or is it made up of tiny particles, like miniature paintballs zipping through space?This fundamental question was at the heart of the double-slit experiment, demonstrating light's dual nature.Just recently, physicists at MIT conducted an experiment using incredible atomic precision.Interestingly, it has definitively resolved a long-standing debate between quantum giants Albert Einstein and Niels Bohr about the elusive nature of light...Einstein believed he could devise an experiment to observe light's particle path and wave interference simultaneously.Bohr, leveraging the uncertainty principle, argued...

Sunspots, those mysterious dark patches on the Sun's surface, have been observed by astronomers for thousands of years. Yet, despite centuries of study, no one fully understood why these spots could remain stable for such extended periods. New research, however, has finally cracked the case, revealing that the secret lies in a delicate balance between the Sun's magnetic fields and the pressure of its plasma. Sunspots have been documented since at least 27 B.C., with Chinese astronomers recording the phenomenon long before Galileo peered at the Sun through his telescope. Some historical records even suggest that Greek philosopher Anaxagoras might...

While the study is intriguing, additional observations will be essential to verify or challenge its findings. Astudy analyzing JWST observations of the early universe has uncovered an intriguing mystery: most galaxies appear to be rotating in the same direction. This unexpected pattern, which defies current cosmological models, has led the study's authors to propose a bold possibility: that our universe might exist inside a black hole. The JWST has allowed astronomers to peer back further into the past than any other infrared or optical telescope, seeing infrared light that was emitted by distant galaxies just 300 million years after the...

The company claims it has cracked a scalable method to make stable gold from mercury. Ever since the discovery of alchemy, or since humans thought gold was a precious object, a worldwide quest to turn common elements into the yellow metal has been ongoing. Folklore and fables sing praises of humans who went on this quest and those who received such blessings. No such claims have yet stood the test of science, and this could change quite soon. An engineering firm from the United States – Marathon Fusion – has claimed that making gold from mercury is possible, and they...

Gravitational waves from massive black holes challenge current astrophysical models The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detected during the fourth observing run of the LVK network on November 23, 2023. LIGO, the Laser Interferometer Gravitational-wave Observatory, made history in 2015 when it made the first-ever direct detection of gravitational waves, ripples in space-time. In that case, the...

That’s the conclusion reached by one researcher from the University of North Carolina: black holes can’t exist in our Universe — not mathematically, anyway. “I’m still not over the shock,” said Laura Mersini-Houghton, associate physics professor at UNC-Chapel Hill. “We’ve been studying this problem for a more than 50 years and this solution gives us a lot to think about.” In a news article spotlighted by UNC the scenario suggested by Mersini-Houghton is briefly explained. Basically, when a massive star reaches the end of its life and collapses under its own gravity after blasting its outer layers into space —...

WASHINGTON (Reuters) - A supermassive black hole appears to be homeless in the cosmos without a galaxy to nestle in, Hubble Space Telescope scientists reported on Wednesday. Most monster black holes lurk at the heart of massive galaxies, slurping up matter from the galactic center with a pull so strong that nothing, not even light, can escape. But a team of European astronomers reported in the journal Nature that a particular black hole some 5 billion light-years away has no evidence of a host galaxy. A light-year is about 6 trillion miles, the distance light travels in a year. The...

Image by Gerd Altmann from Pixabay A University of Alaska Fairbanks (UAF) scientist has proposed a “three-dimensional time” theory that replaces the traditional model of one dimension of time and three physical dimensions as the primary fabric of everything. Unlike previously proposed, purely mathematical ‘3D time’ constructs where space emerges as a secondary manifestation, Professor Gunther Kletetschka at the UAF Geophysical Institute says his theory of everything, which could unify quantum physics and gravity, is testable and verifiable. “Earlier 3D time proposals were primarily mathematical constructs without these concrete experimental connections,” Professor Kletetschka explained. “My work transforms the concept from...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also argues that time comes in three dimensions rather than just the single one we experience as continual forward progression. Space emerges as a secondary manifestation. "These three time dimensions are the primary fabric of everything, like the canvas of a painting," said associate research professor Gunther Kletetschka at the UAF Geophysical Institute. "Space still exists with its three dimensions, but it's more like the paint on the canvas...
