Isn't that what they were saying when Wegner and a few before him suggested
continental movement? And in physics when they thought that they had the
laws described, and there was little to do but confirm them? They had no
idea that there could be any other way to look at things, and basically
denied the possibility.
New data, unexpected experimental results, changed the picture. What that
teaches me is that we probably don't know everything right now, either, and
perspectives may change still.
Right, anything may change but wishful thinking is the last one to achieve such a change. Especially if your "unknown factors" are in violation of known laws.
