What, with all the talk of branes, parallel Universes and other controversial hypotheses it makes it hard to have any confidence in the field of theoretical physics. Theoretical physics came to a standstill more or less with the introduction of the Standard Model, and even that model is built upon experimental result rather than actual theory. The last real "manly" theory was the General Relativity theory, which is now approaching its 1st Century. Don't you guys feel a sense of a lack of confidence in physics; that a radically advanced theory must be proposed that will finally explain things, such as entanglement, or provide a decent model for the Big Bang? Instead, we're getting dubious concepts like superstrings, branes and other absurd ideas that cannot be subject to the experiment, and that do not make heuristic or theoretical sense. Do you guys see the Ultimate Truth as ultimately elusive? That we as a species are just not evolved enough to learn the Secrets of the Universe? Secrets that go beyond relativity or particle physics? That it would take an artificially-intelligent computer with immense processing power to learn these secrets? Entanglement is a 30-year old mystery that has eluded some of the best minds our species can generate. At this point, I'm ready to give up. I'm ready to surrender any faith I have in our species ability to understand the Ultimate Truth. I just don't think we can do it.
