Scientists Have Detected a Faint Hint of The Background Hum of The Universe

by

Ever since scientists made the first detection of gravitational waves from a pair of colliding black holes in 2015, evidence has been growing that the Universe ought to be full of them.   Every massive event – every black hole or neutron star merger, every supernova – should have sent gravitational waves ringing out across … Read more

16-Year Study of Extreme Stars Has Once Again Proved Einstein Is Still Right

by

Two pulsars locked in close binary orbit have once again validated predictions made by Einstein’s theory of general relativity. Over 16 years, an international team of astronomers has observed the pulsar pair, named PSR J0737−3039A/B, finding that the relativistic effects can be measured in the timing of their pulses – just as predicted and expected. … Read more
