  • There is a battle for cosmology that is going on right now. On one side is the mighty firepower of cosmology's standard model. It brings order to everything from the patterns in the big bang's afterglow to the evolution of galaxies. But it can only do so using dark powers. There's dark matter, an additional unseen stuff amounting to a quarter of everything in the universe, which keeps galaxies and clusters of galaxies in line and stops them from flying apart. Far outgunning even this, however, is dark energy. Representing more than two-thirds of the universe, dark energy is a mysterious, expansionist force whose very identity is unknown--but which has dominated the cosmos for the past 5 billion years. Not for much longer as some scientists claim that dark energy's power is a mere illusion created by the machinery of the standard model itself. They now aim to bring it down. Ananthaswamy examines how the universe's dark spectres could be banished.
