No sign of symmetrons yet, physicists report

A high-precision experiment led by TU Wien has set its sights on pinpointing the so-far hypothetical "symmetron fields" using the PF2 ultra-cold neutron source at the Institut Laue-Langevin in France. For the existence of ...

Cosmic voids and galaxy clusters could upend Einstein

It will be possible to use new astronomical mappings of hundreds of thousands of cosmic voids and galaxy clusters to test Einstein's theory of relativity by looking for small deviations in gravity at vast distances – a ...

Astronomers find 72 bright and fast explosions

Gone in a (cosmological) flash: a team of astronomers found 72 very bright, but quick events in a recent survey and are still struggling to explain their origin. Miika Pursiainen of the University of Southampton will present ...
