Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

(via Sabine Hossenfelder) Zero-point energy is one of the most intriguing phenomena of quantum mechanics. Because quantum particles are also waves, they must always have more than zero energy.

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality. Advanced theories, seeking to unify general relativity and quantum mechanics, ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...
