Call it dark. The cosmic frenzy of dark energy. Trillions of scattering galaxies. What force is flinging them in every direction – and ever faster? Call it dark. It’s an old memory. Dark as the madness of the Dionysian women in ancient Greece who tore apart animals and people. They called it ecstatic frenzy. It was dark energy as an eternal vow of wine and blood. Our oath is with reason’s unblinking eye. Telescopes reveal mutilated bodies of ancient light scattered across the sky. By what? By a larger dark that lasts, a dark that has always been and that only now – and only for us – is ready to be seen.
