Time for light to travel from the core of the sun to us = 100,000 years 8 minutes

We know it takes eight minutes for light to travel from the sun’s surface to the Earth, which is a pretty casual way of saying something that reshaped our universe when we worked it out. But it takes 100,000 years for that light to reach the sun’s surface from the core. The light is continually absorbed and re-emitted through the gigantic ball of nuclear fire, in the solar system’s biggest game of pass-the-parcel, where the parcel is almost all the energy you’ve ever used. One-hundred-thousand years. Neutrinos make the same trip in about two seconds.
