In the realm of science, Vera Rubin's groundbreaking work challenged the assumption that stars in galaxies move according to the planets in our solar system. Her discovery of stars moving at unexpected speeds led to the concept of dark matter, expanding our understanding of the universe. Both Mercury and Vera Rubin's stories illustrate the power of questioning assumptions, striving for precision, and embracing the unexpected to transform our understanding and achieve remarkable results.

    • Dark Matter's Mysterious DiscoveryThe discovery of dark matter, an invisible mass making up over 85% of the universe, challenges our understanding and highlights the importance of data collection and questioning assumptions.

      The universe's mysteries far outweigh our current understanding. Vera Rubin's observation of stars moving too fast led to the discovery of dark matter, an invisible mass that makes up more than 85% of the universe. Despite decades of evidence, scientists still don't fully understand what dark matter is or how it interacts with normal matter. This discovery challenges our current understanding of the universe and highlights the importance of collecting more data and questioning assumptions. The unknowns in the universe are vast, and it takes courage and perseverance to grapple with them.

    • Vera Rubin's discovery of dark matterVera Rubin's discovery of dark matter, which makes up 85% of the universe, challenged the scientific community and remains a mystery with unknown properties, requiring specialized equipment to detect

      Vera Rubin's discovery of dark matter challenged the fundamental understanding of the universe. Despite overwhelming evidence, the astronomical community was reluctant to accept the existence of this unseen matter. However, Rubin's persistence and extensive research in over 60 galaxies left no denying it. Dark matter, which makes up the majority of the universe, is still a mystery. Scientists believe it's a particle, but its properties are unlike anything known to science. It's invisible and cannot be touched, making it incredibly difficult to detect. Researchers are now exploring the deepest parts of the Earth in search of this elusive substance, using specialized equipment to bypass its ability to pass through normal matter. The discovery of dark matter has opened up a new realm of scientific inquiry and continues to challenge our understanding of the universe.

    • The elusive search for dark matterScientists continue to search for dark matter, an elusive substance believed to make up a quarter of the universe, using subtle vibrations caused by particle interactions. Despite decades of searching, no definitive evidence has been found, leading some to consider alternative explanations, such as reworking the laws of gravity.

      The search for dark matter, the elusive and invisible substance believed to make up around 27% of the universe, continues to elude scientists despite billions of particles passing through the Earth and our detectors daily. The metaphor used to describe the detection of dark matter is like a subtle bell, where a slight nudge from a dark matter particle causes a tiny vibration that can be detected. However, the challenge lies in distinguishing these vibrations from the constant bombardment of other particles. To address this, researchers have gone deep underground to shield their experiments from cosmic radiation. Despite decades of searching, no definitive evidence of dark matter has been found, leading some scientists to consider alternative explanations, such as reworking the laws of gravity. Historically, similar situations have occurred, like the discovery of Neptune based on irregularities in Uranus' orbit. In both cases, scientists faced the choice between accepting new observations or rethinking their fundamental assumptions. While the majority chose the former, there is a lingering possibility that dark matter might not exist and that our understanding of gravity needs revision. This idea makes some physicists uncomfortable, but the door to exploring this possibility remains open. The search for dark matter continues, but it's essential to keep exploring alternative explanations to broaden our understanding of the universe.

    • The mystery of dark matter and its impact on our understanding of the universeDespite no direct detection, dark matter's role in the universe is suggested by stars moving too fast, gravitational lensing, galaxy formation, and cosmic matter distribution. It's believed to make up around 5x more mass than normal matter, expanding our knowledge if discovered.

      The discovery of dark matter's role in the universe challenges our understanding of gravity and the composition of the cosmos. Vera Rubin's observation of stars moving too fast led scientists to propose dark matter as an explanation for the additional gravity required. Although it hasn't been directly detected, evidence such as gravitational lensing, the formation of galaxies, and the distribution of matter in the universe suggest its existence. The possibility of redefining gravity still exists, but the mounting evidence for dark matter is compelling. Dark matter is believed to make up around five times more mass in the universe than normal matter, and its discovery would significantly expand our knowledge of the cosmos. Despite the lack of definitive evidence, the pursuit of understanding dark matter continues to motivate scientists, as the nature of science itself is provisional and subject to change.

    • Exploring the 'shadow universe' with dark sector particlesThe universe's vastness and complexity fuel human curiosity and discovery, with potential breakthroughs like the recent subatomic wobble shedding light on dark matter or redefining our understanding of the universe

      The universe is vast and complex, with much still unknown. Particle physicists are exploring the possibility of a "dark sector" of particles that could make up a "shadow universe." This idea, while humbling in its scale, also highlights the human capacity for discovery and understanding. Vera Rubin's work on dark matter is a prime example, as her observations of galaxy rotation led to the hypothesis of this mysterious substance. The recent discovery of a subatomic wobble could be a significant step forward in understanding dark matter or even rewriting our understanding of the universe. Despite the vastness and complexity of the universe, the human curiosity and capacity for discovery are powerful tools.

    • Potential new particle discovery at Fermilab could expand our understanding of the universeScientists are exploring a potential hole in the standard model of physics through the muon g-2 experiment, which could lead to the discovery of new particles and a more comprehensive understanding of the universe.

      Scientists are continually pushing the boundaries of our understanding of the universe, and the discovery of a potentially new particle at Fermilab could be a major breakthrough in physics. The standard model, which attempts to catalog all the building blocks of the universe, may be incomplete as it doesn't explain phenomena like gravity or account for the existence of dark matter and dark energy. The muon g-2 experiment at Fermilab could be revealing a hole in the standard model, hinting towards new particles that could help explain these mysteries. This is an exciting development in the field of physics, as it could lead to a more comprehensive understanding of the universe.

    • New particles could explain muon discrepancyScientists found a difference in muon behavior and Standard Model predictions, possibly hinting at new particles and expanding our understanding of physics.

      Scientists have discovered a tiny but significant difference between the precise measurements of muon behavior in a magnetic field and the theoretical predictions based on the Standard Model. This discrepancy could indicate the presence of new, as-yet-undiscovered particles outside the Standard Model, which would expand our understanding of the fundamental laws of physics. The Standard Model is not considered "broken," but rather incomplete, and scientists are actively working to fill in the missing pieces. This research adds to the ongoing quest for a more comprehensive explanation of the natural world.

    • Fermilab muon g-2 experiment reveals intriguing extra wobbleThe Fermilab muon g-2 experiment has discovered an unexplained wobble, potentially hinting at new physics beyond the Standard Model, including leptoquarks, supersymmetry, or a new force, which could lead to the discovery of dark matter.

      The Fermilab muon g-2 experiment, which aims to validate the original Brookhaven experiment, has uncovered an intriguing extra muon wobble. This wobble could be a sign of new physics beyond the Standard Model, such as leptoquarks, supersymmetry, or even an entirely new force. The potential discoveries of these new particles or forces could have significant implications for our understanding of the universe and could potentially lead to the discovery of dark matter. The scientists involved are excited about the possibilities and are currently exploring these three hypotheses. The next step is to determine the ingredients of this "breadcrumb" clue and uncover the larger "loaf" of knowledge it represents.

    • Unraveling the mysteries of the universeLatest findings at Fermilab could lead to new particles, forces, and answers to fundamental questions about our universe and our place in it.

      Physicists are continually conducting experiments to unravel the mysteries of the universe, and the latest findings at Fermilab might be leading us closer to discovering new particles and forces. The pursuit of new physics is an ongoing, dynamic process that keeps scientists on the edge of the unknown. While it may be difficult for non-experts to fully grasp the technicalities, the excitement lies in the potential for groundbreaking discoveries that could answer fundamental questions about our universe and our place in it. The work being done could potentially shape future textbooks and our understanding of dark matter, among other unsolved mysteries. The thrill of potentially uncovering new knowledge about the universe and our place in it is what drives physicists to continue their research.

    Babbage: The hunt for dark matter

    Babbage: The hunt for dark matter

    Dark matter is thought to make up around a quarter of the universe, but so far it has eluded detection by all scientific instruments. Scientists know it must exist because of the ways galaxies move and it also explains the large-scale structure of the modern universe. But no-one knows what dark matter actually is.


    Scientists have been hunting for dark matter particles for decades, but have so far had no luck. At the annual meeting of the American Association for the Advancement of Science, held recently in Denver, a new generation of researchers presented their latest tools, techniques and ideas to step up the search for this mysterious substance. Will they finally detect the undetectable?

    Episode #185: UnchartedX Swapcast - Sacsayhuaman
    For our third installment in the series of swapcasts we are doing with Ben from UnchartedX, we are joined by Matt from the excellent Ancient Architects YouTube channel. The four of us take a look at Ben's raw footage of the amazing and mysterious megalithic site of Sacsayhuaman in Peru, as well as the remains of beautiful megalithic, polygonal, "cyclopean" masonry in the city of Cuzco below.Unlike Egypt, there is far less information available about these sites, what their true origins are, who built them, and why. We ponder these questions, as well as the questions of how these sites were constructed, as they seem almost unbelievable in the details of the masonry....and yet there they stand. Someone did it. Who they were and how they did it are still mysteries. The video for this episode will be released on all of our YouTube channels, so stay tuned!
