I have for a long time been searching for applications of the philosophy of Wittgenstein, particularly later Wittgenstein, to physics. I believe I have found that application in the work of Peter Putnam, who, building on the philosophy of Sir Arthur Eddington, Everett (of Many Worlds fame), and John Wheeler, constructed, in his private musings, the beginnings of a verbal, syntactical representation theory for quantum physics.
There have been a couple of articles lately about Putnam, starting with this one in Nautilus less than a month ago.
He was a relatively unknown figure who might have been as famous as Wittgenstein himself if not for a meddling mother.
A cosmic void could be distorting how we see the universe expand. Sound from the Big Bang may hold the clues. According to astronomers, Earth and the entire Milky Way galaxy might be located within a vast, low-density region of space—essentially a cosmic void—that causes the universe to expand mo
Instead of a tempest in a teapot, imagine the cosmos in a canister. Scientists have performed experiments using nested, spinning cylinders to confirm that an uneven wobble in a ring of electrically conductive fluid like liquid metal or plasma causes particles on the inside of the ring to drift inward. Since revolving rings of plasma also occur around stars and black holes, these new findings imply that the wobbles can cause matter in those rings to fall toward the central mass and form planets.
The scientists found that the wobble could grow in a new, unexpected way. Researchers already knew that wobbles could grow from the interaction between plasma and magnetic fields in a gravitational field. But these new results show that wobbles can more easily arise in a region between two jets of fluid with different velocities, an area known as a free shear layer.
“This finding shows that the wobble might occur more often throughout the universe than we expected, potentially being responsible for the formation of more solar systems than once thought,” said Yin Wang, a staff research physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and lead author of the paper reporting the results in Physical Review Letters. “It’s an important insight into the formation of planets throughout the cosmos.”
In addition to their high masses, the black holes are also rapidly spinning.
“This is the most massive black hole binary we’ve observed through gravitational waves, and it presents a real challenge to our understanding of black hole formation,” says Mark Hannam of Cardiff University and a member of the LVK Collaboration. “Black holes this massive are forbidden through standard stellar evolution models. One possibility is that the two black holes in this binary formed through earlier mergers of smaller black holes.”
Twin orbs of superhot plasma at the Milky Way’s center known as the “Fermi bubbles” contain inexplicable clouds of cold hydrogen, new research reveals. They could help scientists figure out when our galaxy’s black hole last erupted.
The researchers behind these findings uncovered the Infinity Galaxy while examining images from the JWST’s 255-hour treasury COSMOS-Web survey. In addition to the suspected direct collapse black hole that sits between the colliding galaxies, the team found that each nucleus of those galaxies also contains a supermassive black hole!
“Everything is unusual about this galaxy. Not only does it look very strange, but it also has this supermassive black hole that’s pulling a lot of material in,” team leader and Yale University researcher Pieter van Dokkum said in a statement. “The biggest surprise of all was that the black hole was not located inside either of the two nuclei but in the middle.
We asked ourselves: How can we make sense of this?
The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large Hadron Collider at CERN. This effect, known as charge–parity (CP) violation, has been theoretically predicted, but hitherto escaped observation in baryons. The experimental verification of this asymmetry violation in baryons, published in Nature this week, is important as baryons make up most of the matter in the observable universe.
Cosmological models suggest that matter and antimatter were created in equal amounts at the Big Bang, but in the present-day universe matter seems to dominate antimatter. This imbalance is thought to be driven by differences in the behavior of matter and antimatter: a violation of symmetry known as CP violation.
This effect has been predicted by the Standard Model of physics and observed experimentally in subatomic particles called mesons more than 60 years ago, but never previously observed in baryons. As opposed to mesons, which are formed by two quarks, baryons are formed by three quarks—particles that make up most of matter such as neutrons and protons are baryons.
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.

These black holes were whirling at speeds nearly brushing the limits of Einstein’s theory of general relativity, forcing researchers to stretch existing models to interpret the signal.
“Black holes this massive are forbidden by standard stellar evolution models,” says Professor Mark Hannam from Cardiff University. “One explanation is that they were born from past black hole mergers, a cosmic case of recursion.”
Using the James Webb Space Telescope (JWST), an international team of astronomers has performed deep and high spectral resolution imaging of a distant protocluster of galaxies, designated A2744-z7p9OD. Results of the new observations, published July 8 on the arXiv preprint server, shed more light on the properties of this protocluster, revealing that it hosts a remarkably evolved core.
Galaxy clusters are collections of hundreds to thousands of galaxies bound together by gravity. Such clusters are the most immense gravitationally bound structures in the universe, and therefore they could serve as excellent laboratories for studying galaxy evolution and cosmology.
Of special interest for astronomers are studies of protoclusters of galaxies—the progenitors of clusters. These objects, found at high redshifts (over 2.0), could provide essential information about the early phases of the universe.
