A blast from the past? The east coast of Australia was once lined by volcanoes that were so explosive they could shoot sand-sized particles 2300 kilometres – all the way across to the west coast.
The volcanic activity occurred 100 million years ago, at a time when New Zealand began tearing away from Australia’s eastern edge.
Until recently, the only evidence of the scale of these eruptions were the 20-kilometre-wide dormant craters and the solidified lava flows left behind.
But now, Milo Barham at Curtin University in Western Australia and his colleagues have found that these eastern Australian volcanoes flung material to the other side of the country.
UCI physicists confirm possible discovery of fifth force of nature
Light particle could be key to understanding dark matter in universe
Irvine, Calif., August 15, 2016 – Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according to a paper published in the journal Physical Review Letters by theoretical physicists at the University of California, Irvine.
“If true, it’s revolutionary,” said Jonathan Feng, professor of physics & astronomy. “For decades, we’ve known of four fundamental forces: gravitation, electromagnetism, and the strong and weak nuclear forces. If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the universe, with consequences for the unification of forces and dark matter.”
