Does dark matter exist?
“As modern cosmologists rely more and more on the ominous “dark matter” to explain otherwise inexplicable observations, much effort has gone into the detection of this mysterious substance in the last two decades, yet no direct proof could be found that it actually exists. Even if it does exist, dark matter would be unable to reconcile all the current discrepancies between actual measurements and predictions based on theoretical models. Hence the number of physicists questioning the existence of dark matter has been increasing for some time now. “
I’m no physicist, but I have a pretty good grasp of the scientific method and of statistics, and if your theory requires massive forces that you’ve been unable to actually detect despite decades of trying, then it might be that your theory needs revision.
I know that the Einstein relativity-based model of the “large” things in the universe is incompatible with the quantum model of the “small” things, even though both have been tested and shown to work. I understand (somewhat) how string theory might bridge the gap between the two models, but I can’t recall what it says about dark matter. Regardless of whether string theory ever develops into a standard testable model, it’s time to dump this whole dark matter thing and start looking for better answers.
