Theorists seek dark matter in hot neutron stars
Dark matter is an enigma wrapped in a conundrum. We have lots of gravitational evidence for the presence of dark matter. In fact, the evidence is from so many different types of observations, and is all so consistent, that...
Cosmology and dark energy revealed by geometry of galaxy pairs
The Universe strikes a balance between simplicity and complexity that cosmologists are increasingly coming to understand. Recent observations of supernovae and the large-scale distribution of galaxies leave us with the confoundi...
Is it now or never for dark matter WIMPs?
For several decades, astronomers and cosmologists have been piling up data that indicates most of the matter in the Universe is dark, interacting only via gravity. As modified theories of gravity failed to account for observatio...
Cheap and cheerful gravity wave detector on the horizon
Gravity waves seem to be the ultimate in hard-to-detect phenomena. Currently, we have a couple of rather large laser interferometers and a giant suspended pendulum looking for them, so far without success. Furthermore, astronome...
Astronomy and particle physics race to replace Standard Model
If energy issues seem to be attracting the attention of a lot of physicists, the Large Hadron Collider seems to be drawing the attention of many of the rest of them, including people in fields...
A short history of the history of the Universe
John Mather, along with George Smoot, won the Nobel Prize for his work on the Cosmic Background Explorer (COBE), the probe that first caught glimpses of fluctuations in the Cosmic Microwave Background (CMB) left over...
Recent observations show dark matter unobserved again
One of the things that isn't widely advertised in science is that progress often looks a bit like this video—things get done, but the results are rarely quite what you expect. A...
