Dark Matters

By Roger Colins

Dark matter has been driven to the forefront of investigation since the search for Higgs Bosons came to an abrupt end last year, following a 5.9 sigma result.
The next LHC labs fired up in CERN, Switzerland are the 'CMS' Compact Muon Spectrometer and the Toroidal LHC Apparatus, 'ATLAS'. Bods will tweak and twang their instruments, spin the accellorator and see how much dark matter and or, dark energy, they can find.

But it's dark, which means you can't see it, right? Dark matter was first proposed by Jan Oort and then Fritz Zwicky because there's a missing 95 per cent of all matter that should be in the universe. Historically, to observe the wind we only need see the leaves blow but with dark matter, it isn't going to be that easy. If looking for the ether, or where sub atomic particles go when they take a vacation, even measuring the disparity between absolute zero and Planck might not even make dark matter flinch, especially if it is just the left over 'ash' of larger building blocks.

I would begin with a black hole. Stars are hotter on the outside than they are in the middle so how cold would the core of a black hole be? Shred an atom into it's component parts, further shred your electrons, protons and neutrons into theirs and then try to do it to quantum particles. Strings will certainly leap to the forefront but dark matter cannot be dismissed from the equation.

A black hole could be the best place to start because there if there's anything that might provide this penultimate step, it would be the most powerful accelerators in the universe. The centre of every galaxy is supposed to have one but we can't see them, not just because they're the black, we can see the leaves blow, but because they're also shrouded by their galaxy of stars. A veritable needle in a haystack.

Could we use a magnet then? Gravity of galactic black holes are the anchor for the disc of stars spinning round them. While the black hole eats away at any one that gets too close, what about including the accumulated gravitational force of those stars, on the black hole? They may in turn provide an effect on the monster as well. Gravity may be very weak but we're talking about super massive black holes versus the sum mass of the rest of their galaxy. It is worth consideration.
