An important discrepancy in measurements of the universe’s acceleration has theorists wondering whether we’ve gotten something fundamentally wrong in our understanding of the history of the universe.
At the CSIRO’s Radio-Quiet Zone on Wajarri Yamatji country in outback Western Australia, a team of International researchers have found signals thousands of times fainter than the background radio noise. These signals are far from common – they come from the formation of stars 13.6 billion years ago.
We know that the universe is expanding from our research into red shifts of distant galaxies. Acceleration, though? That’s a little tougher to measure. MinutePhysics explains it all.
