Could Something Missing in the Universe Be Revealed by Ripples in Spacetime?
It is possible that gravitational waves — ripples in spacetime — could illuminate dark energy. These ripples encounter supermassive black holes or enormous galaxies as they traverse space. Because it has been proven that gravitational waves are bent when they pass through or near these objects, dark energy might also have an effect on them. “Gravitational waves can be used probe the nature of dark energy,” Jose Maria Ezquiaga, who co-authored a paper recently published in Physical Review Letters, told SYFY WIRE. “If the dark energy is in its essence a modification of gravity, this will affect the way in which the gravitational waves propagate.”
