摘要：

Experiments and observations over the last two decades have provided strong

support for a "standard" model of cosmology that describes the evolution of the

universe from an early epoch of inflation to the complex hierarchy of structure

seen today. I review the basic physics, astronomy, and history of ideas on

which this model is based. I describe the data which persuade cosmologists that

(as yet undetected) dark energy and dark matter are by far the main components

of the energy budget of the universe. I conclude with a list of open

cosmological questions.
