And forces can be measured, yes? That's why astronomers use dark matter calculations to correctly predict the positions of astronomical phenomena. They had another idea called modified gravity. It didn't work. Dark matter does. Goddidit with magic doesn't do anything.<quoted text>
LOL, gravity is a force, not a unit of measure.
Are you allowed outside without wearing a helmet?
Maybe your god is dark matter? After all, that's all you fundies do - use your god as a placeholder for ignorance. That's exactly what Mark just did, which is why he was unable to provide a better alternative theory that does a better job of explaining the evidence.
