As gravitational wave observatories become more sensitive, we may see the collisions of neutron stars and, possibly, find out what these stellar husks are REALLY made of. We are now in an incredible new era of astronomy where the faint ripples in spacetime caused by distant black hole collisions are being detected and studied. These are the most energetic events in the cosmos and, by “listening in” to their gravitational wave signals, these black hole mergers have finally been directly observed.

Newly spotted ripples in space-time are making waves in the scientific community.
The recent announcement of a second gravitational wave detection by the Laser Interferometer Gravitational Wave Observatory (LIGO) has sparked excitement and enthusiasm even among scientists not directly involved in studying these wrinkles in space and time. Space.com spoke with several astronomers at the 228th meeting of the American Astronomical Society (AAS) in San Diego, California, to gauge their reaction.

On Sept. 14, 2015, our planet experienced a very slight spacetime ripple that was detected by the Laser Interferometer Gravitational Wave Observatory (LIGO). On analyzing the signal, physicists realized these gravitational waves were caused by a black hole merger, some 1.3 billion light-years away. This first gravitational wave event was dubbed “GW150914.” Continue reading Gamma-Ray Burst Detected Near Gravitational Wave Source
In the wake of last week’s historic announcement of the discovery of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO), British physicist and black hole theorist Stephen Hawking was quick to congratulate the US-led collaboration, sharing his excitement for the historic news. Continue reading Hawking: Gravitational Waves Could Revolutionize Astronomy
Gravitational waves have been directly detected for the first time by the LIGO collaboration. For more on this exciting news, read the Discovery News coverage of the announcement. Read on to find out what gravitational waves are and why they are important. Continue reading What You Need to Know About Gravitational Waves
We now live in a universe that we know is humming with gravitational waves. Before the historic announcement on Thursday morning at a National Science Foundation (NSF) meeting in Washington D.C., there were only rumors that the Laser Interferometer Gravitational-Wave Observatory (LIGO) had discovered this key component of Albert Einstein’s General Relativity, but now we know that the reality is even more profound. Continue reading We’ve Detected Gravitational Waves, So What?
In the roller-coaster rumor mill that surrounds some of the biggest physics endeavors of our time, it pays to remain skeptical when extraordinary claims of historic discoveries are made on social media. In a tweet by Lawrence Krauss this morning, the well-known Arizona State University theoretical physicist and cosmologist wrote: “My earlier rumor about LIGO has been confirmed by independent sources. Stay tuned! Gravitational waves may have been discovered!! Exciting.” Continue reading Gravitational Wave Rumors Rumble Social Media
