Fundamental Physics and Dark Matter

For the past ten years or so there has been a lot of speculation about the existence and behavior of nonbaryonic dark matter. In this talk I would like to re-examine the evidence for a non-baryonic dark component, contrasting the theoretical prejudice that Ω = 1 with the Big Bang Nucleosynthesis constraints on the amount of baryonic matter, Ω b ≤ 0.2. Assuming then that such a component does exist, I will present a list of candidates from particle physics to explain this dark matter, and illustrate what I find to be a most exciting development, the fact that all the most likely candidates stand to be ruled out or even detected in the next five to ten years.
