ZA_1_18 Verified Physics & Quantum

ZA_1_18 — Dark Energy and the Cosmological Constant Problem

Dark energy — the mysterious component constituting ~68% of the total energy density of the observable universe — drives the accelerating expansion of space and represents one of the deepest unsolved problems in physics.

ZA_1_16 — Sonoluminescence: Light from Sound and the Mystery of Collapsing Bubbles

Sonoluminescence is the emission of short bursts of light from gas bubbles in a liquid when excited by ultrasonic sound waves. First observed by H. Frenzel and H. Schultes at the University of Cologne in 1934 (multi-bubb
