The origin of Earth’s moon has fascinated mankind for thousands of years and has received scientific attention for over forty years, building on the return of rocks from the moon and the growing understanding of planet formation. The central idea of a giant impact on Earth is widely accepted and physically appealing but the constraints … Continue reading Origin of the Moon | The Royal Society
Quantum mechanics is a foundation of physics, chemistry and materials science. Still, there is an ongoing debate about the emergence of the classical, macroscopic world from the well-understood microscopic world of quantum mechanics. We contribute to this discourse by demonstrating quantum superposition of massive particles at the distance (0.5 m) and time scales (2 s) … Continue reading Quantum mechanics at the macroscopic scale – Mark Kasevich (SETI Talks 2016)
Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the … Continue reading Harry Cliff: Have we reached the end of physics?
This new image of powerful remnants of dead stars and their mighty action on the surrounding gas from the European Space Agency’s XMM-Newton X-ray satellite observatory reveals some of the most intense processes taking place at the centre of our galaxy, the Milky Way. The bright, point-like sources that stand out across the image … Continue reading The Milky Way’s Tumultuous Heart Revealed In X-Rays
