A novel mathematical model of the Universe
suggesting that the whole cosmo might be rotating very slowly, making one entire revolution every 500 billion years. The theoretical framework is fully compatible with the standard cosmological model (ΛCDM), it doesn’t contradict current astronomical measurements and is supported by the expanding paradox interpretation.
The discrepancy between the low and high redshift Hubble constant (H₀), denotes a missing link in the understanding of the spacetime expansion estimate with an angular velocity of ω₀ ~2 x 10⁻³ Gyr⁻¹.
Inspired by Gödel slow rotating dark-fluid variant, the spinning model resolves the conflict between
maximal rotation velocity, avoiding closed time-like loops with a tangential velocity inferior to the speed of light at the horizon. Artwork by @ALCrego_

Happy World Quantum day! Today, we celebrate the incredible world of quantum physics and its potential to revolutionise technology, from computing to cryptography. Let's honour the brilliant minds pushing the boundaries of science and shaping our future. ⚛️
📣 We have beam in the tunnel 💫
Today, the Large Hadron Collider received the first particle beams of 2025. #BeamTime
Protons were injected into the #LHC for the first time since November 2024, when the annual year-end technical stop (YETS) started. This is the fourth year of #LHCRun3, and the new data-taking season is about to begin.
Stay tuned for more #ParticlePhysics news.

In #QuantumMechanics the state of entanglement is a fundamental phenomenon where particles share correlated quantum values regardless of their spatial separation. Detecting and protecting that bonding state from measurements is significantly challenging due to the fragility of that condition.
An alternative method is introduced here called Variational Entanglement Witness (VEW) scheme. The VEW, although still based on inequalities like the Bell theorem, leverages a set of mathematical operators that identify the entanglement states by measuring their expectation values. VEW offers a reliable tool that allows to differentiate without quantifying the degree of entanglement. The strategy improves the overall reliability of detection, minimizing the probability of 𝜓 collapse. The theoretical approach was tested on superconducting chips simulating nonlocal measurements by assessing the post-measurement state to confirm the entanglement preservation.

Happy Pi day! The current date and time (14 March, 1.59pm) resemble 3.14159, the approximation of the mathematical constant Pi, or π. Pi is the ratio of the circumference of a circle to its diameter. The ratio stays the same no matter how big or small the circle is.
