宇宙中最大的谜团之一就是它大部分是黑暗的。也就是说，不仅夜空是黑暗的，而且宇宙中的大部分物质和能量也是黑暗的。对于今天在行星、恒星和星系中可见的每一个原子，宇宙中至少存在五到六倍的“暗物质”。今天的天文学家和粒子物理学家正在寻求解开这种神秘但无处不在的暗物质的本质，它深刻地影响了宇宙结构的形成。暗能量仍然更加难以捉摸，因为我们缺乏从成熟的物理学中出现的候选领域。我将描述通过直接和间接手段测量暗物质的各种尝试，并讨论解开暗能量的进展前景。
One of the greatest mysteries in the cosmos is that it is mostly dark. That is, not only is the night sky dark, but also most of the matter and the energy in the universe is dark. For every atom visible in planets, stars and galaxies today there exists at least five or six times as much "Dark Matter" in the universe. Astronomers and particle physicists today are seeking to unravel the nature of this mysterious but pervasive dark matter, which has profoundly influenced the formation of structure in the universe. Dark energy remains even more elusive, as we lack candidate fields that emerge from well established physics. I will describe various attempts to measure dark matter by direct and indirect means, and discuss the prospects for progress in unravelling dark energy.
