I have a question that I can't figure out. In the Sun, it takes several hundred thousand years for a photon released in the core to reach the surface. Use the speed of light and the radius of the sun to estimate the escape time for a photon from the center of the sun if there were no...

I see where you going... P^2 = a ^3 Comparing 10-squared to 10-cubed. Cubed would be greater. Thanks M=4pi^2a^3 / P^2G Thanks a lot. It seems so simple now.
