In 1917, Albert Einstein inserted a term called the `cosmological constant' into his theory of general relativity to predict a stationary universe. A decade later, when it became clear that our Universe was expanding, Einstein ab andoned the constant calling it the 'biggest blunder' of his life.

However, lately, Einstein's biggest blunder has made a dramatic comeback with scientists discovering an accelerating Universe filled with some form of energy density counteracting gravity. So, is the cosmological constant really the mysterious 'dark energy' or is it something else? How can we hope to unravel this mystery?
