Description
The expansion of the Universe was predicted by Albert Einstein and measured by Edwin Hubble almost eighty years ago. Due to gravity it was expected that the cosmic expansion would slow down over time. Ten years ago observations of distant supernovae aimed at determining the decelaration due to the matter content of the Universe found an apparent accelerated expansion. This surprising results has been confirmed by several other methods and now stands as the greatest mystery in physics today. The talk will present the evidence for this new Dark Energy component and present possible interpretations.
