Here is a thought experiment that doesn't seem to add up.
Suppose you have a unit of mass at rest on the surface of Earth that spontaneously transforms to photos all moving radially outward into space. At some distance (say 1Km) the photons revert back to the original mass but are now 1Km above the surface of the Earth at rest. During this process no external energy has been added.
Now the mass at 1Km above the Earth begins to fall. When it passes it's original location it now has the same mass as when it started but has this additional kinetic energy. Where did this additional energy come from?
