Known physics suggests the early universe should have produced matter and antimatter in equal amounts. Nearly all of it annihilated into radiation, but roughly one extra matter particle survived for every billion pairs—and why that tiny imbalance existed remains one of physics’ deepest unsolved problems.
2+ hour, 59+ min ago (906+ words) The measured net baryon-to-photon ratio is about 6.1 parts in ten billion. Physics can describe the required ingredients for that excess, but no confirmed mechanism made it....
The Universe Changed Its Mind About Expansion
49+ min ago (29+ words) For billions of years, expansion slowed. Then something changed. About six billion years ago, the Universe crossed a strange cosmic threshold. Nothing …...
Open-Source Trifilar Pendulum Brings Low-Cost Inertia Testing to Small
1+ hour, 37+ min ago (691+ words) Every spacecraft that tumbles, spins, or reorients itself in orbit does so according to a property that engineers cannot afford to guess: the mass moment of inertia....
A Century-Old Physics Effect Just Got a New Dimension
6+ hour, 56+ min ago (417+ words) Physicists have uncovered an in-plane Hall response that overturns a century-old assumption about how this famous electrical effect works. The discovery could eventually make multidirectional magnetic sensing possible with one tiny device....
Physicists Map When Lost Qubit Coherence Can Come Back to Life
3+ hour, 15+ min ago (581+ words) A quantum bit that has lost its coherence is usually written off as a casualty of its noisy environment, but a new theoretical study argues that this verdict is often premature — and, more importantly, predictable....
The Three-Layer Model: Why the Same Mistake(pseudoscience) Keeps Wearing Different Clothes
6+ hour, 24+ min ago (328+ words) Three claims, three vocabularies, one structure. A universe steered by focused intention. A quantum field …...
beyond the last observer
7+ hour, 43+ min ago (443+ words) Something can happen without anyone witnessing it.. A star can collapse in a distant galaxy with no observer present, Its light can travel across the universe for billions of …...
