LHC Quark-Gluon Plasma: Primordial Soup Was Soupy
Intro: A New Picture of the Big Bang’s First Moments Researchers at CERN’s Large Hadron Collider (LHC) have peeled back another layer of the universe’s oldest mystery. By recreating fleeting, ultra-hot conditions that existed just after the Big Bang, scientists observed that the primordial quark-gluon plasma — the searingly hot mix of fundamental particles that…

Tracking the Fragile Nucleus: How CERN Probes Cosmic Rays with the Deuteron
Introduction: The Quest to Understand Cosmic Rays Cosmic rays have fascinated scientists for decades. These high-energy particles travel through space and strike Earth’s atmosphere, creating cascades of secondary particles that reveal clues about distant stars and violent events in the universe. At CERN, researchers are pushing the boundaries of our understanding by focusing on one…

Quantum Gravity Calculations Reveal Leading Order Dimension-6 Operators
Introduction Understanding gravity at the smallest scales remains a central challenge in theoretical physics. Recent calculations in quantum gravity have highlighted the prominent role of leading order dimension-6 operators within the framework of effective field theory (EFT). These operators capture the first, and often most consequential, quantum corrections to classical gravity when energies approach the…

Quantum Gravity Calculations Reveal Leading Order Dimension 6 Operators: A New Window into Quantum Spacetime
Overview: Pushing the Frontiers of Quantum Gravity Understanding gravity at the smallest scales has long been a central challenge in theoretical physics. Recent calculations in quantum gravity have spotlighted the first nontrivial corrections beyond the familiar Einstein-Hilbert action: leading order dimension 6 operators. These operators, suppressed by high energy scales, encode how spacetime behaves when…
