Gravity waves – caused by collision of two neutron stars
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 … More “Gravity waves – caused by collision of two neutron stars”
Einstein and discovery of gravity waves
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 … More “Einstein and discovery of gravity waves”
The elusive neutrino – a mysterious subatomic particle that may be a key to the unexplained dark matter of the universe.
The neutrino is a subatomic particle, smaller than a proton and an electron. The neutrino was proposed by Enrico Fermi and his co-workers in 1930-1932 to explain a common nuclear reaction called beta-decay.
Not too long after, Fermi couldn’t get a paper published in Nature because the neutrino concept was too unrealistic, so he switched … More “The elusive neutrino – a mysterious subatomic particle that may be a key to the unexplained dark matter of the universe.”
Collision between two stars – a neutron star and a black hole.
The death of stars.I watched the sun come up this morning over the Sandia mountains. Our sun is all gas, but in the center is compressed so much (4 trillion psi) that a teaspoon of it weighs 1.5 lb.
The nuclear process that gives it energy will stop and our sun will slowly die out … More “Collision between two stars – a neutron star and a black hole.”

Merry Christmas, Happy Holidays, and Forbes.com Posts
This is a very short post to wish you all a very Merry Christmas and Happy Holidays. It was 17F here in Albuquerque this morning, but warmed up to 40F by mid-afternoon. The sun shined all day, and that’s usually the case in New Mexico. I have written three posts on Forbes.com, as a contributor. … More “Merry Christmas, Happy Holidays, and Forbes.com Posts”
A cosmic mystery, Part 1: Gamma Ray Bursts.
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 … More “A cosmic mystery, Part 1: Gamma Ray Bursts.”
Asteroids that hit the earth: Severe Consequences
• Asteroids: Chance that earth will be hit again
• Meteor Crater in Arizona • Sodom and Gomorrah destroyed by a meteor • The asteroid that killed the dinosaurs • Mass extinctions on earth and spiritual implications
Last weekend I stopped at the Meteor Crater in Arizona, just before Flagstaff on I40. It’s a giant … More “Asteroids that hit the earth: Severe Consequences”
