What Gravitational-Wave Astronomy May Reveal

Marcia Bartusiak— Early last year, the field of astrophysics announced one of its biggest discoveries. A cosmic phenomenon that Albert Einstein had predicted a century earlier was at last detected directly. Two massive black holes collided, their spectacular merger generating huge ripples—gravitational waves—in the very fabric of space-time. After spreading

The Enigma of Gravitational Energy

Marcia Bartusiak— To the practiced eye, Einstein’s equations stand as the quintessence of mathematical beauty. When it was introduced in 1915, general relativity was hailed as a momentous conceptual achievement. But for a long time the theory had little practical importance. Although the scientific community embraced general relativity—and recognized Einstein
