Deep underground in rural Victoria, Matteo Volpi is searching for evidence of the cosmic glue that holds the Universe together: dark matter.
Matteo is taking the initial measurements for the study at Stawell Gold Mine where an international team is set to construct a $3.5 million laboratory more than a kilometre underground.
Understanding dark matter is regarded as one of the most important questions of modern particle physics.
“If we nail it, it’s a Nobel Prize winning experiment,” says the project leader Elisabetta Barberio, a University of Melbourne physicist and chief investigator of the Australian Research Council Centre of Excellence for Particle Physics at the Terascale (CoEPP).
The Australian Academy of Science recognised five individuals for their career achievements in 2013.
The search for dark matter was kicked off by Ken Freeman’s discovery that there wasn’t enough matter to hold spiral galaxies like ours together. Continue reading Academy recognition→
In 1998 astronomers made an astonishing discovery—the expansion of the Universe is accelerating. The discovery required a complete rethink of the standard model used to explain how the Universe works.
“Now we know that stars, planets, galaxies and all that we can see make up just four per cent of the Universe,” says Dr Tamara Davis, a University of Queensland astrophysicist.
“About 23 per cent is dark matter. The balance is thought to be dark energy, which we know very little about.”
