- The Quantum Experiment That Breaks Time
The article explores a theoretical quantum experiment combining quantum mechanics and relativity, imagining a 'quantum twin' sent across the galaxy to investigate the quantum nature of time. It references Schrödinger's cat and the twin paradox to question whether one could exist in multiple temporal states simultaneously.
- Big Bang origin theory disputed by scientists
A comprehensive survey of physicists reveals significant disagreement on fundamental scientific questions including the nature of the Big Bang, quantum mechanics interpretations, and unified physics theories. Only 20% of physicists agree with the popular definition of the Big Bang as the moment time started, while 68% view it as a hot, dense state. String theory remains the leading candidate for unifying relativity and quantum mechanics, though only 19% of surveyed physicists support it.
- The Physics of GPS
The article explains how GPS technology relies on physics principles like relativity to function. It discusses the role of satellites and atomic clocks in providing accurate location data.
