It’s a big deal. Not so much perhaps with the way you eat your Wheaties in the morning or balance your checkbook, but in the mysterious world of science which always seems to impact the overall trajectory of our lives it is a major event. This is fascinating stuff. I enjoy following the way science bores into the secrets of how God has designed our existence in the universe and marveling at the brilliance of all He has created. This is just one more step and I love that we live in an age when we can see and learn from so many wondrous revelations and discoveries.

FIRST COSMIC EVENT OBSERVED IN BOTH GRAVITATIONAL WAVES AND LIGHT
by Nancy Atkinson
About 130 million years ago, in a galaxy far away, two neutron stars collided. The cataclysmic crash produced gravitational waves, ripples in the fabric of space and time. This event is now the 5th observation of gravitational waves by the Laser Interferometer Gravitational wave Observatory (LIGO) and Virgo collaboration, and the first detected that was not caused by the collision of two black holes.
But this event — called a kilonova — produced something else too: light, across multiple wavelengths.
For the first time in history, an astronomical phenomenon has been first observed through gravitational waves and then seen with telescopes. In an incredibly collaborative effort, over 3,500 astronomers using 100 instruments on over 70 telescopes around the world and in space worked with physicists from the LIGO and Virgo collaboration.
Scientists call this “multimessenger astronomy.” Continue reading
