Physicists have come up with a new idea for how our universe began, and it could also explain dark matter. They say that if our universe has small extra dimensions, then these can temporarily store energy, causing a “cosmological stasis” in which the universe expands but nothing else happens. Then the stasis ends and dark matter remains. Sounds wild. What are we to make of this?

Quantum Gravity! New Research Explains How Space-Time Could Be Entangled

Could gravitational waves—the ripples in space-time—also be quantum in nature? Scientists believe they might! A new study suggests gravitational waves could induce quantum entanglement, revolutionizing physics and reshaping our understanding of gravity. But detecting these effects requires cutting-edge technology. Will future observatories like LIGO-India unlock the quantum secrets of space-time? Dive into this fascinating discovery and explore the possibilities of a quantum universe! Watch now and join the discussion!

Mediterranean neutrino observatory sets new limits on quantum gravity

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the infinitely small. The solution to this puzzle might lie in the humble neutrino, an elementary particle with no electric charge and almost invisible, as it rarely interacts with matter, passing through everything on our planet without consequences.

For this very reason, neutrinos are difficult to detect. However, in rare cases, a neutrino can interact, for example, with water molecules at the bottom of the sea. The particles emitted in this interaction produce a “blue glow” known as Čerenkov radiation, detectable by instruments such as KM3NeT.

The KM3NeT (Kilometer Cube Neutrino Telescope) is a large underwater observatory designed to detect neutrinos through their interactions in water. It is divided into two detectors, one of which, ORCA (Oscillation Research with Cosmics in the Abyss), was used for this research. It is located off the coast of Toulon, France, at a depth of approximately 2,450 meters.

A Roadmap for AI Governance: Lessons from G20 National Strategies

The rapid evolution of artificial intelligence (AI) is poised to create societal transformations. Indeed, AI is already emerging as a factor in geopolitics, with malicious non-state actors exploiting its capabilities to spread misinformation and potentially develop autonomous weapons. To be sure, not all countries are equal in AI, and bridging the “AI divide” between the Global North and South is vital to ensuring equal representation while addressing regulatory concerns and the equitable distribution of benefits that can be derived from the technology.

Most G20 members have established comprehensive national AI strategies, notably technology giants like the United States, United Kingdom, China, and countries of the European Union. Global South nations such as Brazil, Argentina, and India, despite economic constraints, are demonstrating progress in leveraging AI in areas like social services and agriculture. Future strategies must anticipate emerging threats like Generative AI (GenAI) and Quantum AI, prioritising responsible governance to mitigate biases, inequalities, and cybersecurity risks.
