WHATS IN THIS BLOG: • Einstein is a hero to me. • TV series called Genius. • The God Einstein believed in. • Richard Dawkins missed out. • Einstein defined happiness. • The full God-letter.

ALBERT EINSTEIN IS A HERO TO ME. Always has been. E = mc2 and all that. I was trained as a physicist after all. I even wrote a blog about Einstein’s startling prediction of gravity waves (when two neutron starts collide) and their even more startling discovery in late 2017.

It was surprising to hear about a letter that he wrote the year before he died called Einstein’s God-letter. He was 74 years old and concerned daily about his physical deterioration. But his mind was as sharp as ever.… 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

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. A black hole may be 30 times the mass of the sun, or almost ten million times the mass of the earth, but only 20 miles in diameter, which is mind-blowing.… More
