>electrons can absorb and emit light (photons) as they transition between energy levels within atomsLight is energy without mass but not without matter, as it has wave particle duality. It interlocks with matter at the lowest levels of perceived connection, through quantum reactions.
The energy that binds light to gravity is certainly related to the speed of light in a vacuum, a fundamental limit of information. This limit can summarily be solved by applying another unifying theory: One-Electron Universe.
So there we have it, the interface between light and matter, the one electron that connects all life. The son, and its son the sun for us children. This is the way, but only as a pointer is a string. In C++ formally.
