WHATS IN THIS BLOG: • What are neutron stars? • Scientists record a collision between two neutron stars. • The collision gives a flash of light, so we know where it originates. • The collision creates gold and silver.
I have excerpted some words below from an article in Time Magazine: “What we learned from a never-before-seen cosmic collision,” 30 October 2017.
MY PREVIOUS BLOG WAS ABOUT THE DISCOVERY OF GRAVITY WAVES, WHICH CAME FROM A COLLISION OF TWO BLACK HOLES. To read that article, click here. Then hit back-arrow to return to this blog article.
Now the scientists have gone one better.… More

WHATS IN THIS BLOG: • Gravity waves……what are they? • Upcoming talk on Fracking and Earthquakes (by the Gray Nomad)
GRAVITY WAVES……WHAT ARE THEY? After searching for 30 years, scientists have found and measured gravity waves. This was announced yesterday. Gravity is the pull between the sun and the earth, or the pull between a human and the earth. Einstein one-hundred years ago (1916) published the General Theory of Relativity. In it he predicted gravity waves that would spread across the universe like ripples from a stone dropped into a pond. Except they travel at the speed of light.
But to create a gravity wave, you need to suddenly shift a very heavy object, such as a black hole.… More
