Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances. At this scale, new phenomena could arise. However, the Planck-scale ...

The perfect liquid -- now even more perfect
Ultra hot quark-gluon-plasma, generated by heavy-ion collisions in particle accelerators, is supposed to be the "most perfect fluid" in the world. Previous theories imposed a limit on how "liquid" fluids can ...

'Faster-than-light' particles spark science drama
Oh Albert. Did you get it wrong? In 2011, physics was shaken by an experiment which said the Universe's speed limit, enshrined by Einstein in his 1905 theory of special relativity, could be broken.

Visual assistance for cosmic blind spots
A bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure. However, it must do so constructively. In ...

Vanquishing infinity: Old methods lead to a new approach to finding a quantum theory of gravity
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure. ...
