Valleys of Neptune

Valleys of Neptune

Conversations around the recent astounding news of gravitational waves having been recorded, and do exist, has turned my attention to the universe.  What fathomless, endless magic exists!  This series feels like a beginning.

This from Science Magazine, February 2016:

Long ago, deep in space, two massive black holes—the ultrastrong gravitational fields left behind by gigantic stars that collapsed to infinitesimal points—slowly drew together. The stellar ghosts spiraled ever closer, until, about 1.3 billion years ago, they whirled about each other at half the speed of light and finally merged. The collision sent a shudder through the universe: ripples in the fabric of space and time called gravitational waves. Five months ago, they washed past Earth. And, for the first time, physicists detected the waves, fulfilling a 4-decade quest and opening new eyes on the heavens.
