Sunlight is an "emanation" with a 100,000-year delay

A photon born in the Sun's core does not travel directly to the surface. Inside the star, it constantly collides with particles, getting absorbed and re-emitted in a process known as a random walk.

Because of this, the energy's journey outward takes about 100,000 years. Yet, once it leaves the Sun's surface, the light takes only about 8 minutes to reach Earth.

So, the sunlight on your face is energy that began its journey from the star's interior long before the dawn of modern civilization.
