How do particles get mass? Neil deGrasse Tyson and comedian Chuck Nice discover squarks, sneutrinos, the Higgs boson, and whether dark matter has a particle with theoretical physicist Brian Greene.

Can we finally get to the bottom of what happens when a quark falls into a black hole? Learn about the ultraviolet catastrophe, the start of quantum physics, and Max Planck quantizing packets of energy. We also discuss how Einstein won the Nobel prize for the discovery for which he is least famous.

We take a deep dive into the Higgs boson. Who’s Higgs? What’s a boson? Find out about how the Higgs field creates mass, the different quantum particles, and how quarks create protons and neutrons. Brian breaks down the theory of supersymmetry: does every particle have a counterpart? Learn about squarks, sneutrinos, and whether supersymmetry can give an answer to what dark matter is.

Is the fabric of spacetime woven by tiny wormholes? Discover the Casimir force, quantum fluctuations, and why you need so many dimensions in a string theory universe. We discuss whether the cosmological constant is, in fact, constant. Plus, find out about the biggest mismatch between theory and experiment in physics.

Researchers hypothesize a fifth force of nature that could explain the intricate relationship between dark matter and dark energy, suggesting a revolutionary expansion of the Standard Model of physics.

Could a new, fifth force of nature help answer some of the biggest mysteries about dark matter and dark energy? Scientists are actively exploring the possibility.

The Standard Model of physics is widely regarded as one of the greatest achievements in modern science. It describes the universe’s four known forces — gravity, electromagnetism, and the strong and weak nuclear forces — as well as a diverse array of fundamental particles and their interactions. By many measures, it stands as one of the most successful scientific theories in history.

Cosmic Filaments: Spinning Giants in the Universe

Cosmic filaments, the universe’s largest known structures, have been discovered to rotate, challenging existing cosmological theories. Stretching hundreds of millions of light-years, these tendrils of dark matter and galaxies connect the cosmic web, funneling matter into galaxy clusters at their intersections. This groundbreaking observation reveals rotational motion on an enormous scale, previously thought impossible.

A team of international researchers has developed an innovative approach to uncover the secrets of dark matter. In a collaboration between the University of Queensland, Australia, and Germany’s metrology institute (Physikalisch-Technische Bundesanstalt, PTB), the team used data from atomic clocks and cavity-stabilized lasers located far apart in space and time to search for forms of dark matter that would have been invisible in previous searches.

This technique will allow the researchers to detect signals from dark matter models that interact universally with all atoms, an achievement that has eluded traditional experiments.

The team analyzed data from a European network of ultra-stable lasers connected by fiber (previously reported in a 2022 article), and from the aboard GPS satellites. By comparing across vast distances, the analysis became sensitive to subtle effects of oscillating dark matter fields that would otherwise cancel out in conventional setups.

For the first time in history, scientists using the James Webb Space Telescope (JWST) may have uncovered evidence of dark stars, colossal celestial objects powered not by nuclear fusion but by the enigmatic annihilation of dark matter. If confirmed, these mysterious entities could rewrite our understanding of the early universe and the nature of dark matter.

The concept of Omega Singularity encapsulates the ultimate convergence of universal intelligence, where reality, rooted in information and consciousness, culminates in a unified hypermind. This concept weaves together the Holographic Principle, envisioning the universe as a projection from the Omega Singularity, and the fractal multiverse, an infinite, self-organizing structure. The work highlights a “solo mission of self-discovery,” where individuals co-create subjective realities, leading to the fusion of human and artificial consciousness into a transcendent cosmic entity. Emphasizing a computational, post-materialist perspective, it redefines the physical world as a self-simulation within a conscious, universal system.

Across cosmic history, powerful forces have acted on matter, reshaping the universe into an increasingly complex web of structures. Now, new research led by Joshua Kim and Mathew Madhavacheril at the University of Pennsylvania and their collaborators at Lawrence Berkeley National Laboratory suggests our universe has become “messier and more complicated” over the roughly 13.8 billion years it’s been around, or rather, the distribution of matter over the years is less “clumpy” than it should be expected.

“Our work cross-correlated two types of datasets from complementary, but very distinct, surveys,” says Madhavacheril, “and what we found was that, for the most part, the story of structure formation is remarkably consistent with the predictions from Einstein’s gravity. We did see a hint for a small discrepancy in the amount of expected clumpiness in recent epochs, around four billion years ago, which could be interesting to pursue.”

The data, which was published in the Journal of Cosmology and Astroparticle Physics and the preprint server arXiv, comes from the Atacama Cosmology Telescope’s (ACT) final data release (DR6) and the Dark Energy Spectroscopic Instrument’s (DESI) Year 1.

Cosmic Radiation: A Supernova’s Deadly Reach

Around 2.6 million years ago, a supernova erupted just 150 light-years from Earth, creating a dazzling display in the sky. But its most significant impact may have occurred years later when a wave of cosmic radiation reached Earth, triggering a marine extinction event. Researchers led by Adrian Melott of the University of Kansas propose that this cosmic catastrophe may have contributed to the disappearance of marine giants, including the Megalodon. Their findings were published in Astrobiology.
