  • New theory proposes time has three dimensions, with space as a secondary effect

    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...

    Explanation: Sure, that figure-8 shaped curve you get when you mark the position of the Sun in Earth's sky at the same time each day over one year is called an analemma. On the left, Earth's figure-8 analemma was traced by combining wide-angle digital images recorded during the year from December 2011 through December 2012. But the shape of an analemma depends on the eccentricity of a planet's orbit and the tilt of its axis of rotation, so analemma curves can look different for different worlds. Take Mars for example. The Red Planet's axial tilt is similar to Earth's, but...
  • Earth’s Twisted Sister: How Will We Reveal Venus’ Secrets?

    Near-Term goals for the exploration of Venus include improved remote-sensing from orbital probes. This will tell us more about the gravity and topography of Venus. Improved radar imaging and infrared imaging will fill in more blanks. The team also promoted the idea of a sustained aerial platform, a deep probe, and a short duration lander. Multiple probes/dropsondes are also part of the plan. Dropsondes are small devices that are released into the atmosphere to measure winds, temperature, and humidity. They’re used on Earth to understand the weather, and extreme phenomena like hurricanes, and can fulfill the same purpose at Venus....

    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,...

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

    The Debrief ^ | June 18, 2025 | Christopher Plain
    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...

    If we looked at the Sun during an eclipse through a green filter, this is what it would look like. (ESA/Proba-3/ASPIICS/WOW algorithm) A solar eclipse is a marvel. This quirk of the complex interplay between Earth, the Moon, and the Sun doesn't just remind us of the wonders of the cosmos – it gives us a window into the Sun we rarely get to see. More specifically, with the Moon blotting out the main disk of the Sun, we can see details and features in the solar atmosphere, or corona, that are usually obscured from view. Now, a new satellite...

    Analysis of swabs from China's Tiangong Space Station has revealed a new strain of bacteria sporting new adaptations for surviving outer space. Scientists have discovered a new microbe never-before-seen on Earth inside China's Tiangong space station. The new strain of bacteria, named Niallia tiangongensis after the space station, is a variant of a soil-dwelling terrestrial microbe that can cause sepsis, and was found inside one of the station's cabins. Now, a new analysis of the strain has revealed that the bacterium isn't only one of a kind, but has also picked up some key adaptations that could be helpful in...

    A distant star system that scientists described as abnormal, chaotic, and strange is finally coming into focus, thanks to NASA's James Webb Space Telescope. Using its powerful Near-Infrared Camera (NIRCam), Webb has captured a rare image of one of two known planets orbiting the star 14 Herculis, located about 60 light-years from Earth in the Milky Way.The planet, known as 14 Herculis c, stands out for how incredibly cold it is. While astronomers have discovered nearly 6,000 exoplanets, only a small handful have been directly imaged, and most of those are extremely hot, with temperatures soaring into the hundreds or...

    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...
  • Scientists Are Getting Closer to Finding Evidence of the Fifth Force

    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...

  • Humans Have Smoked Meat For Almost 2 Million Years, Study Suggests

    ScienceAlert ^ | 15 June 2025 | David Nield
    Long before the days of electricity and fridge freezers, meat was preserved by smoke. A new study suggests the practice could stretch back almost 2 million years, and may even be a primary reason our ancestors started making fires in the first place. While the generation of flames is inextricably linked with the rise of humans, in the earliest days it would've required significant time and effort to ignite and keep fires lit. The benefits of preserving meat may have been a key reason why that time and effort was worth it. The study is the work of two researchers...

    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...
