A team at Los Alamos National Laboratory has successfully recreated a significant yet largely overlooked physics experiment: the first recorded observation of deuterium-tritium (DT) fusion. Their updated version of the 1938 experiment, recently detailed in Physical Review C, reaffirms the pivotal role of University of Michigan physicist Arthur Ruhlig. Ruhlig’s original work likely...

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 —...

You can manipulate a black hole as much as you like but you’ll never get rid of its event horizon, a new study suggests. This may sound a little odd, the event horizon is what makes the black hole, well… black. However, in the centre of a black hole, hidden deep inside the event horizon, is a singularity. A singularity is a mathematical consequence, it is also a point in space where the laws of physics do not apply. Mathematics also predicts that singularities can exist without an associated event horizon, but this means that we’d be able to physically...

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...

In a groundbreaking achievement, researchers at Oxford University have successfully demonstrated quantum teleportation between quantum computers, a feat that was previously confined to theoretical discussions and early-stage experiments. The team, led by physicist Dougal Main, managed to create a functioning logic gate between two quantum processors located about six feet apart. This represents a significant advancement in quantum computing, opening new possibilities for quantum networks and the realization of scalable quantum systems. Their work is featured in a study published in Nature, and it marks a pivotal moment in the race to create powerful, distributed quantum computers. Quantum Teleportation: A...

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...

Researchers at Chalmers University of Technology in Sweden carried out nuclear fission reactions in 100 different types of exotic nuclei of elements like platinum, mercury, and lead in a bid to understand the reaction better.In addition to helping us generate cleaner energy in the future, the research also sheds light on how elements are formed in the universe, according to a press release by the institute.Nuclear fission is poised for a comeback after countries worldwide seek newer ways to fuel their energy demands. While wind and solar power plants are being readied at a frantic pace to meet net-zero targets,...

One of history’s greatest “what ifs” is the question of what would have happened had the Germans been able to develop nuclear weapons during the Second World War. The Wehrmacht’s effort to do just that, called the Uranverein, or “Uranium Club,” began in 1939 when German Army physicist Kurt Diebner began to research the potential military applications of nuclear fission. By year’s end, the renowned German physicist Werner Heisenberg had expressed his belief that nuclear fission chain reactions, and thus, eventually, nuclear bombs, might be possible, but only if he had access to enough of a singular substance known as...

University of Seville professor José María Martín-Olalla has published a new solution to a 120-year-old problem regarding matter states at absolute zero that disproves a previous solution offered by famed scientist Albert Einstein. The controversy originally arose in 1905 when Walther Nernst proposed a new approach to the properties of matter as entropy causes them to approach absolute zero (minus 273 degrees Celsius). Dubbed Nerst’s theorem, the concept argued that absolute zero must be inaccessible, or one could theoretically construct an engine that uses absolute zero as a coolant to convert all heat energy into work. This idea goes directly...

Here’s what you’ll learn when you read this story: A new hypothesis from physicists at the University of Portsmouth in the U.K. challenges the long-standing Big Bang Theory as the ultimate origin of the universe. This new “Black Hole Universe” hypothesis, suggests that our universe possibly “bounced” from the formation of larger black hole in another parent universe. While intriguing, the Big Bang Theory is the undisputed cosmological champ for a reason, so it'll take lots of rigorous experiments to confirm its theoretical conclusions. Throughout human history, there has been no greater question than “where do we come from?” This...

If it’s out there, could we observe it soon?Here’s what you’ll learn when you read this story: Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented asteroids to hopefully detect anomalies that could provide evidence of such a force. Although the study shows no fifth force anomaly present in the asteroid Bennu, future explorations of the asteroid Apophis could provide an even better chance to find this elusive force—if it exists at all. According to the current Standard Model, four fundamental...

Planet Earth continues to hide a plethora of secrets that our modern science still seems far from uncovering. One of the most mysterious regions of our world is the southern pole, the Antarctica, where a group of researchers has now found ‘strange radio waves coming from below the ice’.

Now picture those clocks as the most precise instruments humanity has ever built, so accurate that they wouldn’t lose or gain a second for billions of years....

About a century ago, scientists were struggling to reconcile what seemed a contradiction in Albert Einstein’s theory of general relativity. Published in 1915, and already widely accepted worldwide by physicists and mathematicians, the theory assumed the universe was static – unchanging, unmoving and immutable. In short, Einstein believed the size and shape of the universe today was, more or less, the same size and shape it had always been. But when astronomers looked into the night sky at faraway galaxies with powerful telescopes, they saw hints the universe was anything but that. These new observations suggested the opposite – that...

Researchers using NASA's Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. It is so strange it might even offer clues to the mechanism behind events known as fast radio bursts...But a decade-long study with Hubble cast doubt on the magnetar's birthplace. After initial observations with ground-based telescopes shortly after SGR 0501+4516's discovery, researchers used Hubble's exquisite sensitivity and steady...
