Opposite in it's effects to dark matter, dark energy pushes things apart while dark matter pushes things together. Dark energy is predominant in the universe. About 70% is dark energy, 29% is dark matter and 1% is cosmic dust. Dark energy is what is causing the expansion of our universe, and as dark energy "wins" the battle against dark matter, the expansion will become so fast, the universe could end in the big rip, where everything rips apart, even atoms. But don't worry, that won't happen for another ten trillion years.
