Galaxy study validates general relativity on cosmic scale, existence of dark matter

News - Astronomy News

(University of California - Berkeley) While general relativity describes well the behavior of the solar system, Einstein's theory of gravity and spacetime has not been tested on cosmological scales. Now, a team that includes UC Berkeley physicist Uros Seljak has analyzed data on 70,000 galaxies to show that the theory is so far the best description of the universe, at least out to 3.5 billion light years from Earth. Specifically, theories without dark matter do not fit the observations.

Most extreme white dwarf binary system found with orbit of just 5 minutes

News - Astronomy News

(University of Warwick) An international team of astronomers, including Professor Tom Marsh and Dr. Danny Steeghs from the University of Warwick, have shown that the two stars in the binary HM Cancri definitely revolve around each other in a mere 5.4 minutes. This makes HM Cancri the binary star with by far the shortest known orbital period. It is also the smallest known binary.
