Dark Energy

Evidence has been growing that we are living in a very strange universe. Ten years ago, as we were coming to grips with dark matter, observations told us that something else, comprising about 73% of the Universe, is accelerating it. One theory proposed to explain this acceleration is the existence of dark energy. In order to find out what this mysterious energy is, astronomers need to compare astrophysical observations that are at first sight completely unrelated. Understanding the nature of dark energy will have consequences for both astronomy and fundamental physics. The enigma of dark energy cannot be solved without connecting the cosmological properties of the universe to the fundamental properties of matter on the subatomic level: from the infinitely small to the infinitely big.
