A photon created in the Sun's core bounces around for tens of thousands of years before reaching the surface and racing to Earth in 8 minutes.
Inside the Sun's ultra-dense plasma, photons constantly scatter off particles in a sluggish 'random walk.' Once free of the solar surface, light crosses the 150-million-km gap to Earth in 8 minutes 20 seconds.

After finally escaping the Sun's dense interior, sunlight reaches Earth in ~8 minutes 20 seconds.
By encoding binary 0s and 1s into synthetic A, C, G, and T DNA bases, a single gram of nucleic acid can theoretically store ~215 petabytes for millennia without power.
Flash-heating the air channel to roughly 30,000 °C in microseconds causes explosive thermal expansion, generating the supersonic shockwave we hear as thunder.
At a precise combination of temperature and low pressure known as the 'triple point,' water exists simultaneously as ice, liquid, and vapor.
Below 2.17 Kelvin, liquid helium-4 enters a zero-viscosity quantum phase and forms a microscopic Rollin film that creeps upward over beaker walls.
