Stephen Wolfram: computation is the universe’s OS

Mathematica creator Stephen Wolfram has spent nearly 50 years arguing that simple computational rules underlie everything from animal patterns to the laws of physics. In his 2023 TED talk, he makes the case that computation isn’t just a useful way to model the world — it’s the fundamental operating system of reality itself.

Wolfram introduces “the ruliad,” an abstract concept encompassing all possible computational processes. Space and matter, he argues, consist of discrete elements governed by simple rules. Gravity and quantum mechanics emerge from the same computational framework. The laws of physics themselves are observer-dependent, arising from our limited perspective within an infinite computational structure.

On AI, Wolfram sees large language models as demonstrating deep connections between semantic grammar and computational thinking. The Wolfram Language, he claims, bridges human conceptualization and computational power, letting people operationalize ideas directly — what he calls a “superpower” for thinking and creation.

Measuring the quantum extent of a single molecule confined to a nanodroplet

There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability density of the system or elements of the system. But for a confined system, the wave function can be inferred.

Scientists from China have now shown that the wave function’s dependence in space can be determined for a single molecule embedded in a superfluid helium nanodroplet. Their research has been published in the journal Physical Review Letters.

Rare Cosmic Lineup Gives Hubble Close Look at 3I/ATLAS

NASA exoplanet probe tracks interstellar comet 3I/ATLAS to gauge its spin https://www.space.com/astronomy/comets/nasa-exoplanet-probe-…e-its-spin.

NASA’s TESS Reobserves Comet 3I/ATLAS https://science.nasa.gov/blogs/3iatlas/2026/01/27/nasas-tess…-3i-atlas/


On January 22, 2026, the NASA/ESA Hubble Space Telescope observed the interstellar comet 3I/ATLAS nearly perfectly aligned with the Sun-Earth axis, revealing unprecedented jet structures and an extended anti-tail.

Ultrathin kagome metal hosts robust 3D flat electronic band state

A team of researchers at Monash University has uncovered a powerful new way to engineer exotic quantum states, revealing a robust and tunable three-dimensional flat electronic band in an ultrathin kagome metal, an achievement long thought to be nearly impossible. The study, “3D Flat Band in Ultra-Thin Kagome Metal Mn₃Sn Film,” by M. Zhao, J. Blyth, T. Yu and collaborators appears in Advanced Materials.

The discovery centers on Mn₃Sn films just three nanometers thick. Despite their extreme thinness, these films host a 3D flat band that spans the entire momentum space, offering an unprecedented platform for exploring strongly correlated quantum phases and designing future low-energy electronic technologies.

“Until now, 3D flat bands had only been observed in a few bulk materials with special lattice geometries,” said Ph.D. candidate and co-lead author James Blyth, from the Monash University School of Physics and Astronomy.

Researchers discover hundreds of cosmic anomalies with help from AI

A team of astronomers have used a new AI-assisted method to search for rare astronomical objects in the Hubble Legacy Archive. The team sifted through nearly 100 million image cutouts in just two and a half days, uncovering nearly 1400 anomalous objects, more than 800 of which had never been documented before.

New insight into the Origin of Water on the Earth

Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water.

There remains a number of mysteries on our planet including the elusive origin of water on the earth. Active studies suggested that terrestrial water had been delivered by icy comets or meteorites containing hydrous silicates that came from outside the “snow line” – the boundary beyond which ice can condense due the low temperatures. More recent studies, however, have provided observations opposing to cometary origin theory, yet still failing to suggest plausible substitutions for the source of terrestrial water. “Until now, much less attention has been paid to organic matter, comparing to ices and silicates, even though there is an abundance inside the snow line” says planetary scientist Akira Kouchi at Hokkaido University.

In the recent study published in Scientific Reports, a group of scientists led by Akira Kouchi demonstrates that heating of the interstellar organic matter at high temperature could yield abundant water and oil. This suggests that water could be produced inside the snow line, without any contribution of comets or meteorites delivered from outside the snow line.

It’s been an idea that has been around since 1895 but only since the 1960s that it was taken seriously. But the biggest issue is how to make a cable over 36,000km that is light enough and strong enough. We now have the ability to make the materials but can we make them long enough to make it a reality, find out in today’s video.

As puzzling as a platypus: The JWST finds some hard to categorize objects

The platypus is one of evolution’s lovable, oddball animals. The creature seems to defy well-understood rules of biology by combining physical traits in a bizarre way. They’re egg-laying mammals with duck bills and beaver-like tails, and the males have venomous spurs on their hind feet. In that regard, it’s only fitting that astronomers describe some newly discovered oddball objects as “Astronomy’s Platypus.”

The discovery consists of nine galaxies that also have unusual properties and seem to defy categorization. The findings were recently presented at the 247th meeting of the American Astronomical Society in Phoenix. The results are also in new research titled “A New Population of Point-like, Narrow-line Objects Revealed by the James Webb Space Telescope,” posted to the arXiv preprint server. The lead author is Haojing Yan from the University of Missouri-Columbia.

“We report a new population of objects discovered using the data from the James Webb Space Telescope, which are characterized by their point-like morphology and narrow permitted emission lines,” the authors write in their research. “Due to the limitation of the current data, the exact nature of this new population is still uncertain.”
