Alien Probes Could Already Lurk in Our Solar System, Study Says

In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of “universal constructor.”

The theory was further detailed in the 1966 book, Theory of Self-Reproducing Automata, a collection of von Neumann’s writings compiled and completed by a colleague after his death.

In the years that followed, scientists engaged in the Search for Extraterrestrial Intelligence (SETI) considered how advanced civilizations could rely on self-replicating probes to explore the galaxy.

Oldest Known Maya Monument Could Be a Map of The Universe

A monumental complex built by the Maya around 3,000 years ago was modeled on a map of the cosmos, new fieldwork has revealed.

A detailed survey of the Aguada Fénix site reveals that not only was the monument significantly larger than initial surveys suggested – laid out in the shape of a cross with axes measuring 9 and 7.5 kilometers (5.6 and 4.7 miles) – but it was also designed as a cosmogram, an architecture symbolizing the cosmos.

What’s even more remarkable about the structure is that the site contains none of the trappings of social inequality, such as elite residences or sculptures of rulers.

No Clear Cometary Tail in Post-Perihelion Images of 3I/ATLAS

On November 5, 2025, two new images of the interstellar object 3I/ATLAS were released. They show a compact source of light without a clear cometary tail. The coma is not very different in morphology than its appearance in the Hubble Space Telescope on July 21, 2025 (accessible here).

This is surprising in view of NASA’s JPL report here of a non-gravitational acceleration — normalized at a heliocentric value of 1 au:

1. A radial acceleration away from the Sun of 1.1x10^{-6} au per day squared.

Post Perihelion Data on 3I/ATLAS

Reports from the Minor Planet Center (here) and NASA’s Jet Propulsion Laboratory (here) just released new data on the interstellar object 3I/ATLAS following its perihelion passage on October 29, 2025. The new data covers the period between October 31 and November 4.

When compared to previous data obtained on October 5–8, it appears that 3I/ATLAS brightened by a factor of ~5 in the Green-band which is centered at a wavelength of 0.464 micrometers.

The value of the non-gravitational acceleration was reduced by a third relative to the value reported on October 29. This reduction is within the uncertainties. The net detection is now more robust, standing at a level of 3.7 standard deviations.

Nonlocality-enabled photonic analogies of parallel spaces, wormholes and multiple realities

Multiverse and wormholes are experimentally elusive due to dimensional constraints. Here, authors use nonlocal artificial materials and deep learning to emulate photonic parallel spaces, realizing invisible zero-index tunnels and independent optical devices coexisting at the same physical location.

California Needs Supercities—and We Should Build Them Now

My latest, part of my CA Gov run!

These cities could also confront two of California’s biggest crises: homelessness and housing affordability. We could plan from day one for low-income and permanent supportive housing, integrated into neighborhoods rather than hidden on the margins. Additionally, for young people, who have watched the dream of owning a home slip away, these new cities could offer a real future—places where the middle class can afford to live, not just survive.

Supercities would also allow us to build sustainability into the foundation of urban life. Powered by renewable energy, designed around walkability and transit, and filled with parks, green roofs and cutting-edge architecture, they could show the world that growth and environmental responsibility can coexist. California has always been a leader in innovation. Why not apply that same imagination to how we live?

This isn’t fantasy—it’s pragmatism. California’s housing shortage is measured in millions of units. Fixing that within the current system is nearly impossible. Building new cities from scratch is the cleanest, fastest way to meet the scale of the problem. It would put people to work, attract investment and reignite the sense of purpose that once defined this state.

The choice is simple: stagnation or creation. We can let our cities decay under the weight of overregulation and paralysis, or we can build new ones that embody the California ideal of progress. The state that built Silicon Valley, Hollywood and the Golden Gate Bridge shouldn’t be afraid to build again. Supercities aren’t some futuristic fantasy—they’re the bold, realistic solution California needs to revive its economy, house its people and remind the world what ambition looks like.
