Beyond energy, matter, time and space

New particles may yet be discovered, and even new laws. But it is almost taken for granted that everything from physics to biology, including the mind, ultimately comes down to four fundamental concepts: matter and energy interacting in an arena of space and time. (Credit: Carl Wiens)

‘Quantum Bounce’ theory claims black holes explode

Kepler's Supernova Remnant "On October 9, 1604, sky watchers -- including astronomer Johannes Kepler, spotted a "new star" in the western sky, rivaling the brilliance of nearby planets. "Kepler's supernova" was the last exploding supernova seen in our Milky Way galaxy. (Credit: NASA/ESA/JHU/R.Sankrit & W.Blair)

Europe targets black holes with next big space mission

This artist’s impression shows a galaxy releasing material via two strong jets (shown here in red/orange), as well as through wide-angle outflows (shown in gray/blue). The black hole at the galaxy’s center drives both jets and outflows. (Credit: ESA/AOES Medialab)

Reinterpreting dark matter

This figure shows that a comparison of the distribution of matter is very similar on a large scale between wave dark matter, the focus of this research, and the usual dark matter particle. (Credit: UPV/EHU)

Droplets and pilot waves vs quantum mechanics

The story is that Bush et al. at MIT did some playful experiments with droplets and the conclusion is supposed to be that this strengthens the case for de Broglie’s pilot wave theory. (Credit: Motl)
