Graham,

Thanks for the mention.

While I agree there is far more we don't know, than what we do, I think the problem of dark matter might be better explained by re-arranging our assumptions about what we do know.

The problem is that there is far more gravitational effect, than matter to explain it, given the asumption that gravity is an effect of matter, so there must be a bunch of invisble matter. Yet what is matter? What is gravity?

Matter is what is physically stable and gravity is this attractive force it seems to generate, which Einstein described as a curvature of space.

Yet how does matter come to be? Wouldn't it be more reasonable to explain matter in terms of gravity, rather than the other way around?

Consider the premise of quantization; That the act of measuring helps to create what we measured. What was diffuse and probable becomes focused and stable. Which goes to the very edge of physical reality and our perception of it. Essentially quantization is a form of contraction and consolidation, that starts with measuring light as photons. So rather than looking for missing mass to explain the gravity, wouldn't it be more logical to look for the gravity directly?

The point I keep making about time is that as these mobile organisms, our sequential process of perception is a function of navigation, so we experience time as the point of the present moving past to future, yet 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 what is present, which is always reconfiguring itself, creating time. So the energy goes past to future, while the patterns generated go future to past.

Think in terms of a wave; The energy drives it, while the fluctuations rise and fall.

Yet as these biological organisms, it is our gut and heart processing and circulating the energy, while the mind sorts and orders the information precipitating out. Consequently we try to explain everything in terms of the information. Signals from the noise. So everything is either order or chaos.

Now think of how that explains how we try to understand everything in terms of the forms generated, the fluctuations rising and falling, the quanta emerging from our detectors. This information comes into being and it is quickly entered into the record, as the observers and detectors go onto the next measurement. Measurement to the past, as observers to the future.

Now consider the premise of waves as frequency and amplitude; We can only know them as the wave has crested. Otherwise all our detectors would sense is increasing pressure. Sothe clarity of information is a function of the inward coalescing of energy, the wave cresting. It isn't that gravity bends the light, the light bending is gravity.

That is where all that extra gravitational effect is.
