I'm not a believer in Dark Matter.
Shhh. Thats a secret. The evidence still isn't convincing for its existence.
Works well to complicate theories, however.
The simplest test I can think of would be this:
Dark matter interferes with the baryonic matter via gravitic coupling.
This should affect local 'speed of sound' measurements, including angle of shockwaves from transsonic objects.
So measure the shockwaves from a test mass moving through local space at a considerable velocity. It would be trivial to calculate shockwave angle from the known velocity and from the observed particle density.
There should be a considerable discrepancy.
This would be an experiment in local space. After all, if there is Dark Matter anywhere, it should be here as well.
If it isn't here, then where did it go?
Also, gravity measurements of 'known mass' volumes of space would show excess mass of around +75%.
Problem is, I haven't heard of a way to measure the gravitational field of say a few cubic kilometers of interplanetary real estate.
...RenegadeMime would like to point out that this post officially enters me into the ranks of Internet Nuts, and would like me to feel free to experiment with different fonts and colours.
