Dark side of the 바카라 사이트

From all we know about the 바카라 사이트, something like 96% of its total matter-energy component is missing! All we see and detect directly in the 바카라 사이트, the familiar baryon matter, atoms, accounts for only about 4% weight of the 바카라 사이트. Dark matter and dark energy, together, the dark side of the 바카라 사이트 are invisible to our telescopes and they dominate over the dynamic of the cosmos and its structure and still we do know what they are. In my talk I review the current status of cosmology and how we try to understand these mysterious components of our 바카라 사이트. The talk would be understandable for general public and under-graduate students.
