When listening to world science festival’s latest episode on youtube, Pondering the Imponderables: The Biggest Questions of Cosmology, I found myself to be most in line with George F.R. Ellis’ line of thinking overall.

Big Bang cosmology, chemical and biological evolutionary theory, and associated sciences have been extraordinarily successful in revealing and enabling us to understand the development of the.

Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much effort, none of the new particles proposed to explain dark matter have been discovered. In a review that was published in Nature this week, physicists Gianfranco Bertone (UvA) and Tim Tait (UvA and UC Irvine) argue that the time has come to broaden and diversify the experimental effort, and to incorporate astronomical surveys and gravitational wave observations in the quest for the nature of dark matter.

Over the past three decades, the search for dark matter has focused mostly on a class of particle candidates known as weakly interacting massive particles (or WIMPs). WIMPs appeared for a long time as a perfect dark matter candidate as they would be produced in the right amount in the early universe to explain dark matter, while at the same time they might alleviate some of the most fundamental problems in the physics of elementary particles, such as the large discrepancy between the energy scale of weak interactions and that of gravitational interactions.

Matter ejected from a spinning disc of doom surrounding a black hole a mere 15,000 light years away has produced some of the most energetic rays of light ever witnessed from an object of its kind.

The insanely powerful photons of gamma radiation were produced by a never-before-seen phenomenon surrounding a miniature quasar. The discovery could help us better understand what goes on deep in the chaotic heart of the Milky Way.

SS 433 is a smaller version of the kinds of maelstrom of death you’d find lurking at the core of most galaxies. It’s also in our neighbourhood, more or less, making it relatively easy to study.

What trouble could a coin-sized black hole cause?

Scientists and religious leaders joined forces to create programs on neuroscience, cosmology—and even some evolutionary science.

With help from dark matter annihilation, some of the universe’s earliest stars were able to grow much larger than they would otherwise.

A new map of dark matter all over the universe could reveal things scientists don’t know about dark energy.

Primordial black holes that formed early in the universe’s history could shed light on how exactly the universe formed.

Today, an international group of researchers, including Carnegie Mellon University’s Rachel Mandelbaum, released the deepest wide field map of the three-dimensional distribution of matter in the universe ever made and increased the precision of constraints for dark energy with the Hyper Suprime-Cam survey (HSC).
