Dark Energy
Dark energy is a form of energy of which almost nothing is known, except that it exists. It can be detected from the expansion of the universe, which increases with time. Measured values signify that the dark energy makes 72% of our universe, three times as much as the dark matter. So far, there are neither observations nor mathematical models, which could explain the nature of the dark energy. Most plausible is maybe the vacuum energy, because quantum mechanics doesn't allow an absolutely empty vacuum.
