What does the discovery of gravitational waves say about inflation and the big bang?

Gravitational waves are ripples that carry energy across the universe. They were predicted to exist by Albert Einstein in 1916 as a consequence of his General Theory of Relativity. Although there is strong circumstantial evidence for their existence, gravitational waves have not been directly detected before. This is because they…

Einstein’s theory of relativity holds up in deep space

Some 7,000 light years away, Einstein’s theory of general relativity has stood up to its most intense test yet, scientists said on Thursday. The project involved observing a massive, fast-spinning star called a pulsar, and its companion white dwarf — a smaller but very dense star that is dying, having…

CERN to re-run Einstein particle tests

GENEVA (Reuters) – Physicists are to run new tests in May after the CERN research institute said on Thursday that its startling findings appearing to show that one of Einstein’s fundamental theories was wrong could have been caused by a loose cable. The CERN lab near Geneva appeared to contradict…

Einstein’s ‘Nazi’ letters to be auctioned in the U.S.

Three letters by Albert Einstein to a American-German group which campaigned against the Nazis in Germany in the 1930s will go on the auction block in Los Angeles next week. In one, the father of relativity praises the “Friends of Truth,” a Cincinnati-based German-American group, for not allowing Jews to…

Study rejects ‘faster than light’ particle finding

(Reuters) – An international team of scientists in Italy studying the same neutrino particles colleagues say appear to have travelled faster than light rejected the startling finding this weekend, saying their tests had shown it must be wrong. The September announcement of the finding, backed up last week after new…
