Einstein's cosmological constant replaced with 'hysteretic universe' theory
A theoretical physicist proposes replacing Einstein's static cosmological constant with a dynamic Preisach model of hysteresis to describe a "living, hysteretic universe." This new model, termed the "non-constant Preisa…

Physicists explore if speed of light limit can be overcome
The speed of light, often considered an absolute limit, may not be unbreakable according to emerging theories in physics. While Special Relativity suggests faster-than-light (FTL) travel and communication are impossible…
