Maybe it's just energy and information.

We are mobile organisms, so we evolved this process of sequential perception, in order to navigate. The effect is that we experience time as the point of the present, moving past to future.

The reality is that change turns future to past. Tomorrow becomes yesterday, because the earth turns.

There is no literal 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 is the present, creating time, as well as temperature, pressure, color and sound. Time is frequency, events are amplitude.

So the energy as present, goes past to future, while the patterns generated go future to past. Energy drives the wave, while the fluctuations rise and fall.

As consciousness goes past to future, while the perceptions, thoughts and emotions giving it form and structure go future to past.

So if you think of what is described as "mass," it is a force we can assign quantity.

Presumably there is a lot of "missing mass," because the assumption is that gravity is a property of mass and there is far more gravitational effect than mass to explain it.

Yet gravity is a centripetal effect and mass is a dense state of energy, so wouldn't it be more logical to assume mass is an effect of this concentration of energy?

If the most elemental form energy expresses is waves, waves tend to either synchronize, which is centripetal, or harmonize, which is centrifugal. So there are nodes and networks, organisms and ecosystems, particles and fields.

The primary dynamic of the universe are galaxies, which are energy radiating out, as structure coalesces in. One centrifugal, the other centripetal. Then the excess gravity is the synchronization across the much broader spectrum.

Just some thoughts and connections to consider.
