One of the greatest mysteries in the whole of science is the prospect that 75% of the Universe is
made from a mysterious substance known as 'Dark Energy', which causes an acceleration of the cosmic expansion.
The lecture will review the current evidence for Dark Energy and future international projects such as the "Dark Energy Survey".
