BBC Science and Environment Astronomers have discovered a unique triple star system which could reveal the true nature of gravity. They found a pulsar with two white dwarfs all packed in a space smaller than Earth's orbit of the Sun. The trio's unusually close orbits allow precise measurements of gravity and could resolve difficulties with Einstein's theories. The results appear in Nature journal and will be presented at the 223rd American Astronomical Society meeting.
