The reality, it turns out, is not quite so simple. Questions about what the universe is, how it began, how it works and where it is going have exercised the minds of some of the smartest scientists of the 20th Century and, while huge strides have been made in pinning down the science underlying the workings of the universe, some stubborn obstacles still remain. In fact, it does sometimes seem that the more we learn and the more questions we answer, the more there is to learn and the more new questions arise. Nevertheless, this website tries to summarize some of the main theories and topics in modern physics and astrophysics without getting into too much serious mathematics, but at the same time without dumbing it down to the point of uselessness. It attempts to tread the fine line between the two extremes: providing sufficient accurate and hard information and explanation, but without too much confusing detail. It attempts to cover some of the fundamental topics in 20th Century physics such as the Big Bang, black holes, quantum theory, special and general relativity, etc, as well as touching on fascinating concepts such as dark matter and dark energy, wormholes, the Big Crunch, the Big Freeze and the Big Rip, superstrings, curved space-time, the
