Abstract: In this paper gives a rather theoretical introduction into particle physics aspects of the cosmological dark matter and energy puzzle. A fairly comprehensive list of possible candidates is given; in each case the production mechanism and possible way to detect them are described. I then describe detection of the dark matter, in my view, most promising candidates, dark matter in galaxies, scientists closer to observing dark matter, Higgs boson may unravel dark energy mystery, How do black holes get super massive? and How dark matter works? in slightly more detail. The main emphasis will be on recent developments.
