    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...

    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...
  • New Solution to 120-Year-Old ‘Absolute Zero’ Problem Shows Einstein was Wrong

    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...

    Study Finds ^ | June 12, 2025 | Rob Coyne, University of Rhode Island
    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...

    Imagine harnessing power on a scale almost unimaginable. A cutting-edge laser facility called ZEUS at the University of Michigan has reached a groundbreaking level of power. It generated a brief pulse of light with a power output exceeding the entire world’s electricity consumption by a factor of one hundred. The powerful laser facility has set a new U.S. record by achieving two petawatts (2 quadrillion watts) of peak power, almost doubling that of its closest competitors. Interestingly, the laser’s immense power lasted just a fleeting 25 quintillionths of a second. Yet, in that fleeting moment, ZEUS can unlock profound scientific...

    For centuries, most scientists have shared the belief that light behaves as both a wave and a particle. This idea, then, became the central component to quantum theory, sprouting the field of science known as quantum mechanics. The double-slit experiment supported the idea, showing bright and dark bands that indicated wave-like interference. But now, a new study suggests that this experiment might not lock us into seeing light as a wave. According to the experts, we can interpret those interference bands using quantum particles alone. The research was led by Gerhard Rempe, the director of the Max Planck Institute for...

    Atoms have been seen clumping up, pairing up, and staying alone thanks to a new technique. Image Credit: Sampson Wilcox Scientists now have a new approach to study never-before-seen quantum phenomena. Physicists from the Massachusetts Institute of Technology have produced the first images of atoms freely interacting in space, showing correlations that had been predicted in theory but never directly photographed before. The team’s Atom-Resolved Microscopy is done in this way. Atoms are allowed to move about and interact freely. The researchers then turn on a lattice made of light that, for a fraction of a second, freezes the atoms....

    For the first time, physicists have demonstrated a phenomenon known as the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp before our eyes. The new findings, a collaboration between TU Wien and the University of Vienna, once again confirm a key prediction of Einstein’s theory of relativity by making an optical illusion of relativistic motion observable for the first time. Terrell-Penrose Effect According to Einstein’s special theory of relativity, objects moving close to the speed of light experience unusual effects, including changes in length and time compared to objects at rest.

    The new theory, developed by physicists at Aalto University, describes gravity in a way that’s compatible with the Standard Model of particle physics, opening the door to an improved understanding of how the Universe began. The Standard Model of particle physics describes electromagnetic, weak, and strong interactions, which are three of the four known fundamental forces of nature. The unification of the fourth interaction, gravity, with the Standard Model has been challenging due to incompatibilities of the underlying theories — general relativity and quantum field theory. While quantum field theory utilizes compact, finite-dimensional symmetries associated with the internal degrees of...
  • Scientists Build First-Ever 'Black Hole Bomb' Analog

    Researchers have created the first laboratory analog of the 'black hole bomb', a theoretical concept developed by physicists in the 1970s. If there's one thing black holes are known for, it's their insatiable, inescapable gravity. Stuff goes into a black hole. From beyond the event horizon, this is, as far as we know, true. But from the space around a black hole, you might be able to get something. As Roger Penrose proposed in 1971, the powerful rotational energy of a spinning black hole could be used to amplify the energy of nearby particles. Then, physicist Yakov Zel'Dovich figured out...
