[QUOTE="Umbran, post: 6853994, member: 177"] Just to be clear, this has little to do with the string theory part of the discussion. To my knowledge, string theory does not remove the need for "dark matter" or "dark energy" to explain the behavior of the universe on the large scale. Not that I'm aware. The problem isn't, "The theory makes predictions, but our machines aren't good enough yet." The problem is that the predictions string theories make are the same as those made by conventional models. So, there's nothing to say that string theory is the real thing we should be using. String theory is, at best, as good as the simpler models we already have, and doesn't give us anything fundamentally different. I've seen one argument that string theories suggest that the force of gravity should be material-dependent. So, the pull of the Sun on a metallic asteroid should be different from the Sun's pull on an icy comet of the same mass. However, I've never seen any prediction of *by how much* the pull should be different. Just that they might be different. If you can't make a *particular* prediction, it doesn't count. We can put on top of that the fact that (again, to my knowledge) nobody has observed such variance. It has to be pretty darned small to have eluded our notice, if it is there. [/QUOTE]
