A/Prof Dr Joan Vaccaro, of Griffith’s Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called ‘T violation’ could be the origin of time evolution and conservation laws. “I begin by breaking the rules of physics, which is rather bold I have to admit, but I wanted to understand time better and conventional physics can’t do that,” Dr Vaccaro says.

“I do get conventional physics in the end though. This means that the rules I break are not fundamental. It also means that I can see why the universe has those rules...

The fact that they share peaks at the same wavelength shows that they belong to the same source. At bottom right, the Keck I and Keck II Telescopes at Hawaii’s the W. M. Keck Observatory.

Discovery could help explain how ‘cosmic dark ages’ ended. Using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii, the researchers detected the galaxy as it was 13 billion years ago. The researchers made the discovery using gravitational lensing to see the incredibly faint object, which was born just after the Big Bang...

An in-depth look at the origins of matter and the environmental conditions that helped shape the universe today. Our understanding is shaped by re-creating events that constituted the Big Bang and by studying the primordial soup of fundamental particles of the very early universe. One of the best science tools for this is the Relativistic Heavy Ion Collider (RHIC), a DOE Office of Science User Facility at Brookhaven National Laboratory.

RHIC, a particle collider, is the first machine capable of mashing together heavy ions, which are atoms that h...

It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.

The MicroBooNE detector – a so-called time projection chamber filled with 170 tons of liquid argon – spotted neutrinos that were generated when proton beams from Fermilab’s accelerator complex slammed into a target a few hundred yards away from the detector.

Researchers from Department of Energy’s SLAC National Accelerator Laboratory are developing tools for the acquisition of the experiment’s data and for the reconstruction of...
