초록: The Universe was hidden in a dark space for a long time. However recent astrophysical and cosmological observations revealed that our Universe is mostly made of unknown dark matter and dark energy except 5% of ordinary matters. In this talk I would like to talk about what are dark matter and dark energy, how they are discovered and what we are trying to do to know more about them.
