TWO COSMIC MYSTERIES. I have personally encountered two cosmic mysteries early in my career – like about 40 years ago. They both involved massive, unprecedented sources of energy. The mysteries continued for decades and occasionally the two encounters kept popping up in my memory. Only in the last few years have both these mysteries been solved – and both explanations involve black holes. This is Part 1. Part 2 will come later.

GAMMA RAY BURSTS. I flew into Los Alamos, New Mexico in 1972 to work at the famous scientific laboratory there (only an hour and a half drive from where I now live in Albuquerque). My job was to study data recorded by satellites (called Vela) that looped around the earth – data on high energy protons and electrons specifically.… More

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. They’ve detected gravitational waves from a collision between two neutron stars. This event was detected on 17 August 2017.… More
