I don't have any formal physics education, so this might seem off the wall, but consider the issue of time.

We think of it as the point of the present moving past to future, which physics codifies as measures of duration, but isn't that an artifact of the fact that as mobile organisms, we experience our world as a sequence of perceptions, in order to navigate?

Yet isn't the reality that change turns future to past?

Tomorrow becomes yesterday, because the earth turns. Duration is the present, as the events coalesce and dissolve.

In which case, 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.

So time is an effect, like temperature, pressure, color and sound. Time is frequency, events are amplitude.

Energy is conserved, because it is only present . As such, it goes past to future, while the patterns/information generated go future to past.

Energy drives the wave, while the fluctuations rise and fall.

(As consciousness goes past to future, while the perceptions, emotions and thoughts giving it form and structure go future to past, but that's a tangent.)

Now looking at the largest scale, aka, galaxies. The energy radiates out, while the structure coalesces in.

So which is entropy? Is it the classic entropy of lost/radiating energy, or is it the structure gravitating in?

One going to the future, as the other goes to the past.

Since the elemental information is waves, they tend to synchronize, which is centripetal. All collecting into the one loop in the middle. Or harmonize, as the energy radiates out, equalizing across all structures.

Gravity is a centripetal effect, so could it be an aspect of the waves synchronizing and all the excess gravity is synchronization across the entire spectrum?

At the center of galaxies are not only the black holes, but the quasars shooting out the poles. Given they amount to giant lasers and lasers are synchronized light waves....

So we have nodes and networks, organisms and ecosystems, particles and fields.

I've been banned for this, so take it for what it's worth.
