The history of cosmology, along with the rest of science, is replete with popular theories which have eventually been jettisoned by the evidence, and wholly unintuitive and implausible realities being confirmed by repeated experiment. The Universe, it turns out, is how it is whether we like it or not.
But it has been suggeted that the Nobel Prize for Physics in 2013, awarded after the discovery of the Higgs Particle may be the last ever awarded to a theoretical physicist, because it becomes ever more difficult to collect experimental evidence to prove mathematical theory. How, for example, can we prove or disprove other Universes which by definition we can never visit? Given the predictive success of mathematics so far, could we ever satisfy ourselves cosmological truths of things we could never test, based on mathematics alone?
Articles in this section of the web site explore, month-by-month, theories yet to be proven by experiment: some already widely accepted, some provocative, others work-in-progress even by the theorists. On this web site, you're very welcome to give your opinions and reasoning, in the comments below each article.
