Einstein
More than any other equation in physics, E = mc² is recognizable and profound. But what do we actually learn about reality from it?
two particles different wavelength speed of light
The Michelson-Morley experiment of 1887, despite expectations, revealed a null result: no effect. The implications were revolutionary.
For centuries, Newton's inverse square law of gravity worked beautifully, but no one knew why. Here's how Einstein finally explained it.
how many planets
From size to mass to density and more, each world in our Solar System is unique. When we compare them, the results are truly shocking.
A computer-generated visualization shows particle collision data with yellow lines and red dots against a black background. The simulated particles appear to interact within a transparent geometric shape.
Today, the Large Hadron Collider is the most powerful particle physics experiment in history. What would a new, successor collider teach us?
Dark matter's hallmark is that it gravitates, but shows no sign of interacting under any other force. Does that mean we'll never detect it?
