New data from the largest 3-D map of our universe suggests we may be wrong about dark energy. One of the driving forces behind that evolution is also one of our age's biggest mysteries in physics: dark energy. Einstein abandoned the idea as his "greatest blunder" in the 1930s, as astrophysicist Ethan Siegal explains, but a constant dark energy would have vindicated him. "If true, it would be the first real clue we have gotten about the nature of dark energy in 25 years," Adam Riess, a Nobel laureate for his co-discovery of dark energy, told Quanta Magazine. "The idea that dark energy is varying is very natural," Paul Steinhardt, a Princeton University cosmologist, told the magazine.
