Splitting and recombining an electron wave packet has been used to test relativity at a record sensitivity. The result heralds an era of precision measurements of relativity using quantum-information ...

In physics, the term “isotropy” means a system where the properties are the same in all directions. For fusion, neutron energy isotropy is an important measurement that analyzes the streams of ...

The latest data from the Planck satellite have consolidated our understanding of the cosmic microwave background and the early Universe — except for some large-angle anomalies. These effects could be ...

The standard model of Cosmology makes an important assumption: that the Universe is essentially isotropic, the same in all directions. This is a pretty good assumption, and so far isotropy seems to be ...

No matter where we look, the same rules apply everywhere in space: countless calculations of astrophysics are based on this basic principle. A recent study by the Universities of Bonn and Harvard, ...
