If Earth were at the middle of the solar core, how long would it take to destroy the planet?
Furthermore, how would the planet be destroyed?
To consider the planet to be destroyed, it must be ripped apart in some senses. I'd imagine that the Surface of the Earth would continuously melt and disperse into the sun, until nothing is left.
I've done some research and found that the Sun's energy output is roughly e26, and the gravitational binding energy of earth is e32. So that suggests it would take at least e6 seconds for the Earth to be destroyed.
