Before ascribing a personality to our subject perhaps we ought, first, to ask what is matter? If dark matter acts as if it were matter, does it follow that it must so be? Could be be talking about a proto-particle having the essence but not (all of?) the elements associated with matter as generally understood? Just a thought.

Mmm... understood.

If one were to subscribe to a torus universe (donut theory) where a big bang is more of a big through (or even a continually expanding and contracting universe) one could theorise a succession of universes existing in parallel to one another outside of what we laughingly call time in a multiplicity that is in fact a repeating sequence of a single universe.

One man's scientific orthodoxy is another man's pseudoscience. The (social-Darwinist and Eugenicist) science of Galton and Pearson was considered cutting-edge in its day.

Hello, Doughnut here - education: PhD. Interested in science in a philosophical context.

I read recently a theory that: "Dark matter is not matter but a state – a structural pre-existent existencethat precedes matter – the submerged iceberg, the tip of which is manifested inthe universe as matter." Presumably this 'state' leaves a solid footprint. Any thoughts?

What are the latest ways to reduce the weight of aircraft, cars and ships? Are we talking new metal alloys or engineering practice?
