Second detection heralds the era of gravitational wave astronomy - Guest Work

Guest Work Jun 16, 2016

By Paul Lasky, Monash University Earlier this year, a team of over 1,000 scientists from across the globe announced the first discovery of gravitational waves and the first ever observation of colliding black holes. That same team has now published a second gravitational-wave observation from another cataclysmic black hole death spiral, detected on Boxing Day, December … Read More

Gravitational Waves - Physics Stop

Marcus Wilson Feb 12, 2016

The big breaking physics news is the detection of gravitational waves. These waves are distortions in space-time, caused by a large mass doing something spectacular (two colliding black holes in this case)  that propagate across the universe and create tiny changes in space when they reach us. The commentary here describes what goes on. Essentially, things change … Read More

The logic of journal embargoes: why we have to wait for scientific news - Guest Work

Guest Work Feb 12, 2016

Vivian Siegel, Massachusetts Institute of Technology Rumors were flying through the blogosphere this winter: physicists at the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) may finally have directly detected gravitational waves, ripples in the fabric of space-time predicted by Einstein 100 years ago in his general theory of relativity. Gravitational waves were predicted to be produced by … Read More

What happens when LIGO texts you to say it’s detected one of Einstein’s predicted gravitational waves - Guest Work

Guest Work Feb 12, 2016

Chad Hanna, Pennsylvania State University The best thing about a day in my life on the lookout for gravitational waves is that I never know when it will begin. Like many of my colleagues working for the Laser Interferometer Gravitational-Wave Observatory (LIGO), the morning of Monday, September 14, 2015 caught me completely off-guard. For years, we’ve been … Read More

New Windows on the Universe - Guest Work

Guest Work Feb 12, 2016

By Professor David Wiltshire As researchers with the Laser Interferometer Gravitational-Wave Observatory (LIGO) announce they have spotted gravitational waves – ripples in space itself set off by violent astrophysical events – University of Canterbury Professor of Physics Dr David Wiltshire discusses what it means. The announcement that gravitational waves have been directly captured for the first time ever, from the … Read More

From bosons to Bigfoot: six science mysteries that might be solved in 2016 - Guest Work

Guest Work Jan 05, 2016

Gavin Hesketh, UCL; Louise Gentle, Nottingham Trent University, and Simon Cotton, University of Birmingham From the origin of life to the fate of the universe, there’s plenty scientists simply don’t know. But they are making progress. 2015 has been a great year for science: we’ve seen the agreement of climate deal, pictures of dwarf … Read More
