No Bang. Just Currents — Eric Lerner, DemystiCon ‘25, DemystifySci #348

Physicist and fusion researcher Eric Lerner presents a sweeping critique of the Big Bang theory and the standard model of cosmology at Demysticon 25. He builds on the foundations of plasma physics and the work of Nobel laureate Hannes Alfvén to outline an alternative cosmological framework rooted in known physical laws—gravity, nuclear fusion, and electromagnetic plasma behavior—rather than hypothetical concepts like dark matter, dark energy, or cosmic inflation. He explores how filamentary plasma structures may account for galaxy formation, how fusion research using dense plasma focus devices parallels cosmic processes, and how the cosmic microwave background may not be relic radiation from a singular origin. Merging astrophysics, plasma cosmology, and energy research, this talk reframes the origin and structure of the universe—and calls into question the prevailing narratives at the heart of modern theoretical physics.

This Ultra-Thin Drumhead Moves Sound With Almost No Loss — And May Change Tech Forever

When a drummer hits a drum, the surface vibrates and creates sound—a signal we recognize as music. But once those vibrations stop, the signal disappears. Now imagine a drumhead that’s incredibly thin, only about 10 millimeters wide, and covered in tiny triangular holes. Scientists have created exactly that, and it does something extraordinary.

Researchers at the Niels Bohr Institute in Copenhagen, working with teams from the University of Konstanz and ETH Zurich, discovered that vibrations can travel through this miniature membrane with barely any energy loss. In fact, the vibrations move more cleanly than signals in even the most advanced electronic circuits. This breakthrough, recently published in Nature, opens up new possibilities for how we transmit sound and information, especially in the race toward powerful new quantum technologies.

Open House

Have you heard about the crazy guys who bought an entire tower to convert it into a vertical village? Yes, that’s us.

Do you want to walk the 16-floor tower and explore the space? Still on the fence, if you should become a citizen? Do you have questions about how you can get involved and co-create? Wanna hear updates on what happened in the last 2 weeks? This event is for you! 👩‍🚀

About us: We are transforming a 16-floor tower in the heart of San Francisco into a self-governed vertical village —a hub for frontier technologies and creative arts. 8 themed floors will be dedicated to creating tier-one labs, spanning AI, Ethereum, biotech, neuroscience, longevity, robotics, human flourishing, and arts & music. These floors will house innovators and creators pushing the boundaries of human potential in a post-AI-singularity world.

Satyendra Nath Bose

Satyendra Nath Bose FRS, MP [ 1 ] (/ ˈ b oʊ s / ; [ 4 ] [ a ] 1 January 1894 – 4 February 1974) was an Indian theoretical physicist and mathematician. He is best known for his work on quantum mechanics in the early 1920s, in developing the foundation for Bose–Einstein statistics, and the theory of the Bose–Einstein condensate. A Fellow of the Royal Society, he was awarded India’s second highest civilian award, the Padma Vibhushan, in 1954 by the Government of India. [ 5 ] [ 6 ] [ 7 ]

The eponymous particles class described by Bose’s statistics, bosons, were named by Paul Dirac. [ 8 ] [ 9 ]

A polymath, he had a wide range of interests in varied fields, including physics, mathematics, chemistry, biology, mineralogy, philosophy, arts, literature, and music. He served on many research and development committees in India, after independence. [ 10 ] .
