Energy made in the core of the sun can take many thousands of years to work its way out.

Astronomy Facts, sourced to NASA.

What it means

The interior is so dense that a photon travels only a tiny distance before being absorbed and re-emitted in a random direction. The result is a drunken stagger rather than a journey, and it takes an enormous number of steps to cover the distance from core to surface. Once free of the surface, the same energy crosses the gap to Earth in eight minutes.

The claim comes from NASA, and the page it comes from was read on 2026-08-27 to confirm it still says this.

This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
