Stars bolster Einstein’s theory

Astronomers have observed a dwarf star in the Musca constellation with a mass so great that it distorts space-time. Its companion, a pulsar, orbits the dwarf star in a rapid five-hour cycle. The white dwarf, though Earth-sized, is far denser. The pulsar, a supernova remnant, emits neutrons. The white dwarf's gravity and spin cause frame-dragging, affecting the pulsar's motion. This phenomenon, observed by Australian telescopes, supports Einstein's theory of general relativity.
