Gravitational waves

UPDATE: (Science Alert) – New satellite data from the European Space Agency (ESA) reveal that the mysterious anomaly weakening Earth’s magnetic field continues to evolve, with the most recent observations showing we could soon be dealing with more than one of these strange phenomena. The South Atlantic Anomaly is a vast expanse of reduced magnetic […]

The New Yorker wrote an article calledGravitational Waves Exist The Inside Story of How Scientists Finally Found ThemThe article describes how Professor Rainer Weiss idea to build a device sensitive enough to detect ripples in space-time became aprofessional obsession and a quest that spanned ahalfcentury This quest had a team of over 1000 scientists and engineers focused on the task

Evidence of gravitational waves may be in our reach by the end of the year, says scientist. Also; Pluto's small moons tumble in constant chaos, and Hubble detects the first intergalactic supernovae.

MIT Technology Review: Tidal forces carry the mathematical signature of gravitational waves

When black holes merge strong gravitational waves are emitted. The graph shows a state-of-the-art comparison between waveforms of a black hole binary calculated according to two different techniques (top panel); the lower panel shows the final few cycles, including the merger of the two black holes.

When you emit gravitational waves, they have to pass through the Universe. But do they gravitate, too?
