New breakthroughs in molecular diffusion and visible singularities, reshaping science with applications in chemistry, physics, and cosmology.
Quantum foam itself released gravitational waves that eventually shaped the cosmic universe.
Over billions of years, these stretched ripples grew into clumps of matter, forming the first stars and galaxies. Eventually, they created a massive network of galaxies and dark matter called the cosmic web, which spans the entire universe today.
A new study suggests that the cosmic web could have formed without relying on inflation driven by a scalar field. Instead, it proposes a novel mechanism that suggests that inflation arises from gravitational wave amplification.
Inflation is believed to have laid the foundation of everything there is out in space. However, nobody knows when it happened, why it happened, or what caused it. Plus, scientists don’t have any solid evidence to confirm whether it happened.

How Symmetry Shapes the Universe: A Peek into Persistent Symmetry Breaking.
Imagine a world where certain symmetries—like the balance between left and right or up and down—are spontaneously disrupted, but this disruption persists regardless of temperature. Scientists are exploring this fascinating behavior in a special type of mathematical framework known as biconical vector models. These models examine how symmetries behave under specific conditions, especially in a universe with two spatial dimensions and one time dimension (2+1 dimensions).
This study takes a closer look at these models and reveals exciting new insights about symmetry breaking in a way that respects established physical principles. Here’s what the researchers discovered:
1. Symmetry Breaking Basics: The study confirms that symmetry can break persistently when these models are designed to include both continuous and discrete symmetry features (described by the mathematical groups O(N)×Z₂). This breaking shifts from one type of symmetry (O(N)×Z₂) to another (O(N)) as temperature rises, but only under certain conditions.
2. Precision at Zero Temperature: By using advanced computational methods, the team accurately described how these models behave when the temperature is absolute zero. Their findings are valid for a wide range of systems, provided the number of components, N, is 2 or greater.
In the fascinating intersection of quantum computing and the human experience of time, lies a groundbreaking theory that challenges our conventional narratives: the D-Theory of Time. This theory proposes a revolutionary perspective on time not as fundamental but as an emergent phenomenon arising from the quantum mechanical fabric of the universe.

“In a sense, Nature has been continually computing the ‘next state’ of the Universe for billions of years; all we have to do — and actually all we can do — is ‘hitch a ride’ on this huge ongoing [quantum] computation.” — Tommaso Toffoli
In my new book Temporal Mechanics: D-Theory as a Critical Upgrade to Our Understanding of the Nature of Time (2025), I defend the D-Theory of Time, predicated or reversible quantum computing at large, which represents a novel framework that challenges our conventional understanding of time and computing. Here, we explore the foundational principles of D-Theory, its implications for reversible quantum computing, and how it could potentially revolutionize our approach to computing, information processing, and our understanding of the universe.
Quantum computing is drawing more attention now than generative AI did before ChatGPT’s release. This sparks big questions about what QC could achieve in 2025.
Researchers experimentally demonstrated counterflow superfluidity, a quantum state where atoms flow in opposite directions simultaneously.
Even so, many wonder: If the universe is at bottom deterministic (via stable laws of physics), how do these quantum-like phenomena arise, and could they show up in something as large and complex as the human brain?
Quantum-Prime Computing is a new theoretical framework offering a surprising twist: it posits that prime numbers — often celebrated as the “building blocks” of integers — can give rise to “quantum-like” behavior in a purely mathematical or classical environment. The kicker? This might not only shift how we view computation but also hint at new ways to understand the brain and the nature of consciousness.
Below, we explore why prime numbers are so special, how they can host quantum-like states, and what that might mean for free will, consciousness, and the future of computational science.
