About Physics on Plax
Physics asks how the universe works at every scale, from particles and light to energy, forces and the cosmos. Stories summarise research reports and explain their results in plain language.
Many physics ideas begin with an everyday question. Why the sky is blue is a good one: our guide shows how scattering explains blue skies, red sunsets and white clouds.

- Why the sky is blue, and why sunsets are red
The colour of the sky comes from the way air molecules scatter sunlight. The same physics explains red sunsets, white clouds and the black sky on the Moon.
