One factor to take into consideration is the basic map versus territory issue. The function of the map, the model, the framing device, is not to include all information from the territory, or it would revert back to noise. Whiteout.
So any science, math, field is a framing device with some central focus and method. Different frames can be applied to the same spaces, processes, like different fields of math can be cross referenced.
So the question is whether there is some deeper element to which all these devices refer?
I would pose it is the relationship between energy and form/information.
As mobile organisms this sentient interface our body has with its situation functions as a sequence of perceptions, in order to navigate, so our sense of time is as the present going past to future, yet the evident reality is that activity and the resulting change turns future to past. Tomorrow becomes yesterday, because the earth turns.
There is no dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.
Energy is conserved, because it manifests this presence, creating time, temperature, pressure, color and sound. Frequencies and amplitudes, rates and degrees.
So the energy, as present, goes past to future, because the patterns generated come and go, future to past. Energy drives the wave, the fluctuations rise and fall. No tiny strings necessary.
Consciousness also goes past to future, while the perceptions, emotions and thoughts giving it form and structure go future to past. The digestive system processes the energy, feeding the flame, while the nervous system sorts the patterns, information, as the circulation system is feedback in the middle.
So there is this intellectual focus on the information, as opposed to the dynamic driving it, which does create havoc in our efforts to explain everything in terms of the information derived from our senses.
Galaxies are also energy radiating out, as structure coalesces in.
While we like to model space as three dimensions, that is a mapping device, like longitude, latitude and altitude. The conceptual parameters of space are infinity and equilibrium. Which is implicit in the frame with the fastest clock and longest ruler being closest to the equilibrium of the vacuum, the unmoving void of absolute zero.
So the energy is radiating out, toward infinity, as structure coalesces in, toward equilibrium.
It would seem the possible basis for this centripetal effect is synchronization. One big wave is more efficient than lots of small waves.
Consider anything actually falling into the black holes is shot out the poles as quasars, which are like giant lasers and lasers are synchronized light waves.
Thus even the energy actually pulled in is eventually shot out, toward infinity.
One of the issues in cosmology is Dark Matter. That there is far more gravitational effect, than mass to explain it. So what if we are looking at it backwards?
As these tactile organisms, objects tend to be the center of our focus, but what if the properties we associate with mass are simply intermediate stages and feedback between the centripetal effect of structure coalescing and energy radiating? Gravity being a centripetal effect.
Then mass is more an effect of gravity, than gravity a property of mass.
That's my theory of everything.
