The possibility of time travel has fascinated humanity for centuries, fueling both literary imagination and scientific debates. In a study published in Classical and Quantum Gravity, physicist Lorenzo Gavassino explores the thermodynamic and quantum foundations that would sustain life and physical processes in a universe with closed timelike curves (CTCs). Through rigorous analysis, the author […]
Quantum mechanics
Quantum particles observed for the first time to have mass only when moving in one direction
An international team of scientists has achieved a remarkable breakthrough in the study of quantum materials thanks to an experiment conducted in Florida. Using the world’s most powerful magnet, they discovered strange behavior in a material that could have revolutionary applications for future technologies, from batteries to medical devices. The experiment was conducted at the […]
Tiny Black Holes Created at the Beginning of the Universe Could Be Hiding in Hollow Planets, Rocks, and Ancient Buildings on Earth
Black holes result from the collapse of massive stars after they exhaust their fuel, creating regions of spacetime where not even light can escape. However, new research suggests that the chaos of the early universe might have generated black holes much smaller than those commonly known, referred to as primordial black holes (PBHs). These tiny […]
DNA-like geometric structure discovered in space-time
An international team of scientists, composed of researchers from the Complutense University of Madrid, Saint Louis University’s Madrid campus, and the University of California, has proposed a new theory suggesting that spacetime could be made up of “entangled virtual bosons”, similar to the double helix of DNA. This finding, which could have significant implications for […]
Scientists Explain How to Build Time-Traveling Quantum Sensors
Time travel has always fascinated fans of science fiction. While science says traveling to the future is possible if you can move close to the speed of light, going back in time is impossible. But what if scientists could use the strange rules of quantum physics to learn about past events? New research shows this […]
No One Opens Schrödinger’s Cat’s Box: Why Doesn’t the Universe Behave Like Quantum Particles?
A new study in quantum cosmology proposes an innovative approach to address one of the oldest puzzles in physics: the transition from quantum to classical. This transition is crucial for understanding how our universe, full of well-defined stars and galaxies, emerged from a primitive quantum state where things could be in multiple states at once. […]
Physicists announce new theory that unifies Gravity and Quantum Mechanics while preserving Einstein’s concept of Spacetime
Modern physics is based on two pillars. One is quantum theory, which governs the smallest particles in the universe. The other is Einstein’s general theory of relativity, which explains gravity through the curvature of spacetime. But these two theories contradict each other, and reconciling them has been difficult for over a century. The prevailing hypothesis […]
Physicists trap Electrons in a 3D Crystal for the first time
Electrons move through conductive materials like travelers during rush hour in Manhattan. The charged particles can bump and collide with each other but mostly don’t pay attention to other electrons as they zip around at high speeds, each with their own energy. But when electrons in a material are trapped together, they can all reach […]
