(PhysOrg.com) -- For at least half a century, astronomers have been perplexed by so-called runaway stars; big monsters that hurtle around galaxies at some thirty kilometers per second without apparent reason. Now however, ...
All observations in astronomy are based on light emitted from stars and galaxies and, according to the general theory of relativity, the light will be affected by gravity. At the same time all interpretations in astronomy ...
