'Blurred times' in a quantum world

When measuring time, we normally assume that clocks do not affect space and time, and that time can be measured with infinite accuracy at nearby points in space. However, combining quantum mechanics and Einstein's theory ...

Black hole makes material wobble around it

The European Space Agency's orbiting X-ray observatory, XMM-Newton, has proved the existence of a "gravitational vortex" around a black hole. The discovery, aided by NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, ...

Gravitational physics poised for new era of discovery

The recent detection of gravitational waves from the collision of two black holes signals a new era in gravitational wave astrophysics that will allow probing of the Universe in never before known ways, writes a Montana State ...

Scientists' breakthrough in modelling universe

Research teams in Europe and the USA – including a cosmologist from the University of Portsmouth – have begun modelling the universe for the first time using Einstein's full general theory of relativity.
