Finding hints of gravitational waves in the stars

22 septiembre 2014

Scientists have shown how gravitational waves — invisible ripples in the fabric of space and time that propagate through the universe — might be ‘seen’ by looking at the stars. The new model proposes that a star that oscillates at the same frequency as a gravitational wave will absorb energy from that wave and brighten, an overlooked prediction of Einstein’s 1916 theory of general relativity. The study contradicts previous assumptions about the behavior of gravitational waves.
