This material causes potential wells and hills that are exhibited in the late-time integrated Sachs-Wolfeeffect. The FLRW metric shows that one accepted model of this material would need to have negativepressure. In 2011, the Hubble Telescope ruled out a bubble of empty space that was considered analternative to this material. Two proposed forms of this material are quintessence and a type described bythe cosmological constant; those two forms are used in describing a stationary and accelerating universe.For 10 points, name this hypothetical material believed to form the majority of the mass-energy content ofthe universe.
