WebApr 19, 2016 · 1. Photons can produce shock waves in water or air, similar to sonic booms. Nothing can travel faster than the speed of light in a vacuum. However, light slows down in air, water, glass and other materials as photons interact with atoms, which has some interesting consequences. The highest-energy gamma rays from space hit Earth’s … WebFeb 17, 2014 · Dark energy with negative pressure and positive energy density is believed to be responsible for the accelerated expansion of the universe. Quite a few theoretical models of dark energy are based on tachyonic fields interacting with itself and normal (bradyonic) matter. Here, we propose an experimental model of tachyonic dark energy based on …
