3D Time Could Solve Physics' Biggest Problem, Says Bizarre New Study
Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could all be literally a matter of time. Three dimensions of time, in fact. The basic idea of 3D time isn't new. But University of Alaska geophysicist Gunther Kletetschka says his mathematical framework is the first to reproduce known properties of the Universe, making it a somewhat serious contender for uniting physics under one consistent model. "Earlier 3D time proposals were primarily mathematical constructs without these concrete experimental connections," says Kletetschka. Related: "My work transforms the concept from an interesting mathematical possibility into a physically testable theory with multiple independent verification channels." Something is wrong with our current models of reality. While quantum mechanics and general relativity both explain our Universe to a degree that's uncannily accurate, each emerges from fundamentally distinct grounds – one granular and random, the other seamless and immutable. These irreconcilable starting points make it a challenge to construct a single, all-ruling theory of physics that explains gravity in the same way as it does the other three forces. Not that theorists haven't tried. Kletetschka proposes a complete rethink on the basics, pulling back the fabric of space-time itself to come up with a new bedrock to base reality on. While we use the word time to describe virtually any series of events, there's a clear contrast in scale that extends from the near-instantaneous flitting of quantum particles to the eons of cosmic growth stretching into eternity. On the cosmic end, time can be relative, distorting in relation to mass and acceleration. Up close, time is undecided, equally capable of looking to the past as it does to the future. And drifting in the middle is an existence as boringly predictable as tomorrow's sunrise. Separating these scales into their own dimensions provides us with three paths to follow, each marching to its own beat at right angles to the others. By embedding these timelines in mathematics that preserves cause and effect, it's possible to link all three dimensions in a way that could explain everything from how fundamental particles pop up in quantum fields, to why we can't experience quantum weirdness, to the expanding boundaries of the Universe itself. "These three time dimensions are the primary fabric of everything, like the canvas of a painting," says Kletetschka. "Space still exists with its three dimensions, but it's more like the paint on the canvas rather than the canvas itself." Related: Importantly, the framework precisely reproduces known masses of a number of particles, such as top quarks, muons, and electrons, and volunteers predictions for the unknown masses of neutrinos and subtle influences on the speeds of gravitational waves. That means the theory could receive support from future experiments, and potentially contribute to a more united approach to physics as a whole. "The path to unification might require fundamentally reconsidering the nature of physical reality itself," says Kletetschka. This research was published in Reports in Advances of Physical Sciences.

Bright Future: Technology Leaders Look To Quantum
John Prisco, Security CEO & founder of Safe Quantum Inc., working with data-driven companies to develop and deploy quantum-safe technologies Amid the ongoing funding news for bright, young quantum startups (see Classiq, SilQ Connect), recent news from the U.S. Congress and established technology companies is raising the stakes for quantum viability and the need to keep Chinese quantum development within reach. Word on the street is that Nvidia plans to invest in PsiQuantum, the chipmaker's first direct tie to quantum hardware. The move is especially interesting considering the position of Nvidia CEO Jensen Huang, who said earlier this year that a viable quantum computer is still decades away. This move would extend Nvidia's ongoing interest in quantum, which includes quantum software development, a hybrid system framework and a new quantum research lab in Boston that will be devoted to leveraging AI-powered supercomputers alongside advanced quantum hardware. The Nvidia news comes on the heels of other big-name investments in quantum this year. Amazon joined the quantum party, nudging some of its chief cloud rivals like Google and Microsoft in the race for potential payoff when quantum goes commercial. Amazon touted its Ocelot quantum chip (announced a week after Microsoft's own) as a high-efficiency approach to quantum and extending the Amazon Web Services (AWS) cloud-computing platform. Microsoft doesn't plan to allow access to its chip through the Azure public cloud infrastructure, however, focusing instead on building the capacity of its chip to add qubits—quantum bits of data. The flurry of activity isn't a moment too soon if you look at China's movements in quantum. The Chinese announced in April a successful test of perfectly encrypted data communications over 750 miles, an extraordinary distance. It's yet another example of China's emerging dominance in quantum development, a potential threat so serious that Microsoft President Brad Smith warned it puts the United States in jeopardy of falling irrevocably behind. Smith has exhorted the current administration to prioritize quantum research, renewing programs such as the National Quantum Initiative Act and focusing on developing an educational pipeline initiative to cultivate quantum talent. Already this year, a bipartisan group of U.S. representatives banded together to introduce a sandbox program to complement the National Quantum Initiative. The Quantum Sandbox for Near-Term Applications Act aims to provide a cloud-based workspace for government and commercial researchers to experiment with quantum applications for defense, healthcare, energy and manufacturing. There are other bright spots. Cisco, at the heart of the existing internet infrastructure, announced a new quantum lab and the development of a quantum chip prototype designed to enable quantum networks to scale. IBM has partnered with Tata Consultancy Services to launch the largest quantum research and development center in India, alongside an IBM Quantum Systems Two installation with a 156-qubit Heron quantum processor. The Indian investment is on top of IBM's strategy to invest $150 billion (that's BILLION) in the United States over the next five years to expand U.S.-based manufacturing of quantum computers and mainframe systems. With the volume of investment in small and large technology companies, it's clear that quantum's future is calling. No doubt the next few years will also herald a time of mergers and acquisitions, as newer technologies come to market. Smart investors would do well to especially consider companies with a focus on early-stage quantum solutions, such as quantum key distribution (QKD), with proven use cases that deploy quantum today over existing fiber optic networks.

'Time Breaks Down at Quantum Scale': New Scientific Discovery Shocks Physicists and Redefines the Laws of the Universe
IN A NUTSHELL 🔍 Physicists in England discovered two opposing arrows of time in open quantum systems, challenging traditional views. in open quantum systems, challenging traditional views. 🌌 The study suggests time can move in both directions at the quantum level , revealing a symmetrical nature. , revealing a symmetrical nature. ♻️ Entropy continues to increase in both directions of time, prompting a reevaluation of thermodynamic principles. continues to increase in both directions of time, prompting a reevaluation of thermodynamic principles. 🧠 The findings raise profound questions about the nature of reality and time's role within the universe. Time, often perceived as a relentless, forward-moving arrow, is a concept that has intrigued scientists and philosophers alike. While everyday experiences reinforce the notion of time's unidirectional flow, recent research suggests a more nuanced understanding at the quantum level. A groundbreaking study led by physicists in England has revealed the existence of two arrows of time in open quantum systems, challenging traditional views and opening new avenues for exploration in the realms of thermodynamics and quantum mechanics. The Enigma of Time's Arrow Time's arrow, a metaphor for its unidirectional flow, is a cornerstone of our understanding of the universe. Yet, this seemingly straightforward concept has baffled physicists who seek to understand why time flows only in one direction. In classical physics, equations often ignore the directionality of time. For example, a pendulum's motion appears identical whether viewed forwards or backwards. However, in reality, time's arrow is clearly asymmetrical, moving from past to future. This dichotomy raises fundamental questions about the nature of time and its underlying mechanisms. Over two years, a research team in England delved into this mystery, focusing on open quantum systems—systems that interact with their environment. Their findings, published in Scientific Reports, reveal the existence of two arrows of time moving in opposite directions. This discovery not only challenges our traditional understanding but also suggests that time's behavior at the quantum level is more complex than previously thought. 'This One Sentence Changed Everything': Emotionally Intelligent People Swear by This Powerful Phrase to Command Respect and Build Deep Connections Open Quantum Systems: A New Perspective To unravel the mysteries of time at the quantum level, scientists turned their attention to open quantum systems. Unlike closed systems, which are isolated from external influences, open systems interact with their surroundings, resulting in changes over time. This interaction is key to understanding time's passage at the subatomic level. Energy dissipation, or entropy, serves as a proxy for time's flow. As energy dissipates into the environment, it indicates the direction of time. The research team's model demonstrated that these open systems allow for the emergence of two arrows of time, a phenomenon not observed in closed systems. In their equations, the team observed 'slightly modified' results, suggesting that two trajectories—one moving forward in time and the other backward—are equally possible. This duality presents a radical shift in our perception of time, suggesting a symmetrical nature that defies conventional understanding. 'Britain Just Sent This Beast Into the Sky': UK Unleashes First Combat Drone With 5,750-Mile Strike Range Implications for Thermodynamics and Beyond The study's findings have significant implications for fields such as thermodynamics, cosmology, and quantum mechanics. At the heart of these disciplines is the concept of entropy, described by the second law of thermodynamics as a tendency toward disorder. The team discovered that even with two arrows of time, entropy's progression remains consistent, hurdling toward disorder regardless of time's direction. This revelation challenges the notion of irreversible processes and suggests a more complex relationship between time and entropy. As Andrea Rocco, the study's senior author, explains, the results prompt a reevaluation of assumptions about time's function in the universe. While the study does not confirm speculative ideas about time's origins, such as the emergence of twin universes at the Big Bang, it provides a framework for rethinking these concepts. 'They Found a Goblin in the Rocks': On a Unearths Terrifying Jurassic Lizard Bolg With a Face Straight Out of a Horror Film Rethinking the Nature of Time The discovery of twin arrows of time raises profound questions about our understanding of reality. Although the research does not entertain the idea of time travel or constructing time machines, it highlights the theoretical possibility of two equally valid time trajectories. Once the arrow takes a direction, familiar dynamics like entropy come into play, reinforcing time's irreversible nature. Rocco likens the concept to a network of roads, where the paths are visible, but the traffic direction remains unknown. This metaphor underscores the complexity and intrigue surrounding time's behavior at the quantum level. The study's implications extend beyond academic interest, touching upon fundamental issues about the nature of reality and time's role within it. The exploration of time's duality in open quantum systems offers a fresh perspective on a timeless enigma. By revealing the possibility of two arrows of time, the research invites us to reconsider our assumptions and delve deeper into the mysteries of the universe.

Quantum eMotion Announces Successful Completion of Quantum Simulation Project Evaluating Sentry-Q Cryptographic Architecture
Montreal, Quebec--(Newsfile Corp. - June 26, 2025) - Quantum eMotion Corp. (TSXV: QNC) (OTCQB: QNCCF) (FSE: 34Q0) ("QeM" or the "Company"), a developer of quantum-secure technologies, announces the completion of an internal quantum simulation project assessing aspects of its cryptographic architecture. The benchmarking project, conducted in collaboration with PINQ², utilized IBM's Qiskit quantum computing framework to simulate Grover's algorithm—a quantum search algorithm known for its theoretical ability to speed up brute-force attacks on symmetric encryption schemes. The analysis focused on evaluating the relative complexity of attacking symmetric encryption algorithms when enhanced with entropy from QeM's proprietary Quantum Random Number Generator (QRNG). Key Observations: Simulations indicate that the success rate of Grover's algorithm decreases significantly with increasing key size. The integration of QeM's QRNG appears to increase oracle complexity and circuit depth in the simulated quantum circuits, suggesting a higher computational burden for potential quantum attackers. At projected real-world key sizes (e.g., 256 bits), Grover's algorithm would require approximately 2¹²⁸ iterations to succeed, rendering such attacks infeasible with foreseeable quantum hardware. "While our simulations are conducted at small key sizes, the extrapolated trends support a clear conclusion: the integration of our QRNG-generated entropy demonstrates characteristics consistent with strong resistance to quantum attacks," said Dr. Francis Bellido, CEO of Quantum eMotion. "This work strengthens our confidence in the security-by-design approach we are taking with Sentry-Q and our broader post-quantum product roadmap." The project lays the groundwork for future validation in embedded and edge environments. Next-phase development will include hybrid testbenches and real-time emulation of cryptographic architectures enhanced with QRNG under constrained computing conditions. About QeM The Company aims to address the growing demand for affordable hardware and software security for connected devices. QeM has become a pioneering force in classical and quantum cybersecurity solutions thanks to its patented Quantum Random Number Generator, a security solution that exploits the built-in unpredictability of quantum mechanics and promises to provide enhanced protection for high-value assets and critical systems. The Company intends to target highly valued Financial Services, Healthcare, Blockchain Applications, Cloud-Based IT Security Infrastructure, Classified Government Networks and Communication Systems, Secure Device Keying (IOT, Automotive, Consumer Electronics) and Quantum Cryptography. Neither TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release. This press release may contain forward-looking statements that are subject to known and unknown risks and uncertainties that could cause actual results to vary materially from targeted results.
