This week’s report from the Cosmos brings amazing stories ranging from What Existed Before the Big Bang to Forms of Consciousness We Can’t Recognize to World’s Scientists Share Their Expectations for the James Webb Space Telescope.
It’s been said that Newton gave us answers; Stephen Hawking gave us questions. In his famous lecture on “Life in the Universe”, our era’s greatest theoretical physicist, who was laid to rest in 2018 in Scientists’ Corner at Westminster Abbey, between Isaac Newton and Charles Darwin, asked one of his most profound questions: “What are the chances that we will encounter some alien form of life, as we explore the galaxy?”
“Gravitational waves will bring us exquisitely accurate maps of black holes – maps of their space-time. Those maps will make it crystal clear whether or not what we’re dealing with are black holes as described by general relativity,” said Nobel Prize laureate, Caltech’s Kip Thorne. Now, scientists at Cardiff University’s Gravity Exploration Institute are using the technologies behind one of the biggest scientific breakthroughs of the century—the detection of gravitational waves led by Thorne— in the long-standing search for dark matter.
Welcome to an extraordinary catch of news from the Cosmos. Today’s stories range from Why AI Needs a Genome to Our Solar System is a Cosmic Oddity to the Quantum Experiment that Could Prove Reality Doesn’t Exist, and much more.
A gravitational wave isn’t a ripple through objects in spacetime; it passes through spacetime itself. Gravitational waves make the Universe itself vibrate, says Brian Clegg, author of Gravitational Waves: How Einstein’s Spacetime Ripples Reveal the Secrets of the Universe.
