Approximately 14,000 years ago, the unprecedented solar event—now judged to be the most powerful known to have occurred—marked Earth’s transition into the Holocene epoch, according to the findings of an international team of scientists. The team traces the event to around 12,350 BC using a new climate-chemistry model specifically designed to reconstruct ancient solar particle activity. This expands the known timeline for ancient solar storms and raises the bar on the upper boundaries of their intensity. Although the event in question was already known from past observations of radiocarbon spikes in ancient wood samples, its scale and magnitude remained unknown....

On Tuesday, astronomers watched as a vast 'bird wing' eruption sent waves of superheated plasma surging across the sun's northern hemisphere. At over 600,000 miles long (one million km), the filament of solar material was more than twice as long as the distance from the Earth to the moon. Now, scientists predict that part of this filament eruption could hit Earth tomorrow. In a post on X, formerly Twitter, aurora chaser Jure Atanackov predicted that the full force of this eruption could trigger a severe or even extreme geomagnetic storm, the highest level on official rating systems. Stunning video recorded...

When a Nobel Prize-winning physicist, Dr John Clauser, labels the claims about greenhouse gases warming the Earth as “pseudoscience” and describes them as “a dangerous corruption of science,” I urge you to take notice. He further stated that “the IPCC is one of the worst sources of dangerous misinformation,” and remarked that climate science has “metastasized into massive shock-journalistic pseudoscience.”Similarly, Professor Harold (Hal) Lewis, a distinguished physicist, called such claims “the biggest and most successful pseudoscientific fraud” he had encountered in his lifetime. Another German physicist expressed outrage upon discovering that much of what the IPCC and the media presented...

Conceptual image depicting end of the universe by generative AI (© The 2R Artificiality - stock.adobe.com) In a nutshell * Scientists discovered that neutron stars and white dwarfs are slowly evaporating, shortening the universe’s expected lifespan from 10^1100 years to 10^78 years. * All massive objects lose energy through a process similar to how black holes evaporate, with denser objects deteriorating faster. Despite this “earlier” end, the universe’s death is still inconceivably far in the future—neutron stars will last 10^68 years and white dwarfs about 10^78 years. ================================================================================ NIJMEGEN, Netherlands — Scientists have just calculated that our universe will end...

Deep beneath the thick ice that covers East Antarctica, scientists are revealing new discoveries about a mystery that has been hidden beneath the continent’s frozen exterior for half a billion years. According to newly published research, clues to the formation of a mountain range the size of the Alps tucked away below Antarctic ice are being revealed, offering geologists a unique glimpse at the processes behind their formation. The Gamburtsev Subglacial Mountains, initially discovered by Soviet scientists during an expedition in 1958, have puzzled researchers for decades. Now, these massive features beneath Antarctica’s frozen surface, which were formed long ago...

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...

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. Many relativistic...

History has been made by Stratolaunch, a hypersonic flight test research company headquartered in Mojave, California. The fully autonomous Talon-A2, equipped with landing gear, has successfully exceeded speeds of Mach five and completed its second autonomous landing at Vandenburg Space Force Base. This mission documentary follows the first recovered flight of TA-2, the result of five years of effort and dedication marking a pivotal moment in sustainable hypersonic flight test for our country. Congratulations to the Stratolaunch team and partners on this success! Next steps: fly TA-2 again and again, increasing the cadence of hypersonic flight tests for the United...

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...

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...

The Soviet Union launched the spacecraft known as Kosmos 482 in 1972, one of a series of Venus missions. A Soviet-era spacecraft meant to land on Venus in the 1970s is expected to plunge uncontrolled back to Earth, possibly within the first two weeks of May. It's too early to know where the half-tonne mass of metal might come down or how much of it will survive re-entry, according to space debris tracking experts. Dutch scientist Marco Langbroek predicts the failed spacecraft will re-enter around 10 May. He estimates it will come crashing at around 242 kph, assuming it remains...

In 1972 the Soviet union launched two spacecraft to explore the planet Venus, Venera 8 would become the second spacecraft to land on Venus, while the other spacecraft got stuck in Earth orbit and so was designated Kosmos 482. Now, 50 years later we expect the spacecraft to finally fall back to Earth, and unlike most spacecraft this one is designed to survive atmospheric entry. So it could land as a solid mass and maybe there's hardware that will survive, or more likely it will land in the ocean and sink.... 50 Year Old Venus Spacecraft Is About To Land...

Scientists have discovered a groundbreaking phenomenon where light materializes from nothingness, opening the door to revolutionary advances in physics and technology. In a groundbreaking new study, researchers from the University of Rostock and the University of Birmingham have made a surprising discovery that challenges the long-held understanding of time and space in physics. Their research, recently published in Nature Photonics, reveals the existence of “space-time-topological events” where light appears to emerge from and disappear into nothingness—a phenomenon that initially seems like magic, but is grounded in deep mathematical principles. Rethinking Time and Space in Physics Time has long been considered...
