Svetlu treba osam kratkih minuta da stigne do Zemlje sa Sunčeve površine. 
Koliko vremena to isto svetlo putuje iz Sunčevog jezgra do njegove površine?
Neobično, odgovor je mnogo hiljada godina. Sten Odenvald objašnjava zbog čega je to tako kroz ilustraciju problema nasumičnog hoda.

The light that reaches Earth from the Sun may take only eight minutes to cross space, but its journey inside the Sun lasts about 170,000 years. Photons created in the Sun’s core bounce endlessly among dense particles, slowly shifting from gamma rays to visible light. This random walk through turbulent solar layers means every sunbeam is a messenger from a distant past, starting its voyage before humans even wore clothes. The Sun’s inner dynamics turn a simple trip into a labyrinth lasting across ages.
