Dropping Einstein’s universe into a black hole

Scientists are throwing Einstein’s theories into the heart of one of the most dynamic and dangerous arenas of the universe: colliding black holes.

Nearly a century after Einstein published his theory of general relativity, scientists are finding new ways to test its description of the universe. Einstein reimagined the universe as a great fabric composed of both space and time, with neither component as a constant. Instead, the presence of matter and energy bend and warp that fabric to create the force of gravity.

Advanced technology and mathematical models have finally caught up with the 95-year-old theory, which remains the most accepted explanation of universal gravitation.
