Logically "nothing" would be the void. A temperature of absolute zero. Perfect equilibrium.
Which would seem implicit in Special Relativity, as the frame with the fastest clock and longest ruler would be closest to the equilibrium of the vacuum, through which light travels at C.
Yet the conceptual opposite of the absolute would be the infinite. So we fluctuate somewhere between everything cancelling out and everything fading out.
Black holes and black body radiation.
So what is in the middle?
We live in this state called the present, but it keeps changing. As mobile organisms, we experience a sequence of perceptions, in order to navigate, so we refer to this change as time.
Though our experience of time is as the present moving past to future, it would seem that beyond our biological point of view, it is change turning future to past. Potential, actual, residual
Tomorrow becomes yesterday, because the earth turns.
So there is no actual 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 then, is "conserved," because it is only present. It creates time, as well as temperature, pressure, color and sound. Time is frequency, events are amplitude.
So energy, as process of change, goes past to future, while the patterns generated go future to past. In terms of a wave, the energy drives it, while the fluctuations rise and fall.
Galaxies are energy radiating out, toward infinity, while form coalesces in, toward equilibrium.
As consciousness expands out, going past to future, while the perceptions, emotions and thoughts rise and fall, coalescing in, future to past.
Though it is the digestive, respiratory and circulatory systems processing the energy, feeding the flame, while the central nervous sysytem sorts the information. Signal from the noise.
That's why, when we try to think about it, our understanding is order versus chaos, rather than energy and form.
So while information describes, it's the energy that explains.
