New findings have revealed that time ran five times slower in the early universe, after scientists published new research into quasars. A quasar is a luminous active galactic nucleus and studying them has allowed scientists to measure time. The variation in brightness of quasars from the early universe has been measured to determine time dilation back to a billion years after the Big Bang. Experts have found that there was an era in which clocks moved five times slower than they do in the present day. The findings come as a relief to many cosmologists who have been perplexed by previous results that have come from studying quasars. The discovery that the universe is expanding led to the theorisation of “time dilation” – the idea that time moved slower the smaller the universe was. Sign up to our free Indy100 weekly newsletter Professor Geraint Lewis of the University of Sydney, the lead author of a new study, said in a statement: “Looking back to a time when the universe was just over a billion years old, we see time appearing to flow five times slower.” He continued, explaining: “If you were there, in this infant universe, one second would seem like one second – but from our position, more than 12 billion years into the future, that early time appears to drag.” To measure the extent of time dilation, scientists turned to quasars, as they are able to measure their change in brightness over a period they can estimate. The most distant quasar that is visible is 13 billion back in time and can still be seen despite its far distance. Their brightness varies due to turbulence and lumpiness in their accretion disks. Lewis explained the phenomenon as being “a bit like the stock market”. He said: “Over the last couple of decades, we’ve seen there is a statistical pattern to the variation, with timescales related to how bright a quasar is and the wavelength of its light.” Have your say in our news democracy.

India’s Chandrayaan-3 lander only touched down on the Moon a month ago, but already it's made some major contributions to science. The spacecraft arrived on the satellite's unexplored south pole on 23 August, securing India's place as the first country to achieve this ambitious feat. Its rover, named Pragyan (or "wisdom" in Sanskrit) then embarked on an exploration of the rocky terrain, equipped with two instruments for conducting chemical experiments. And now, India's space agency, the ISRO, has published the ground-breaking data collected by the bold robot. Pragyan's findings offered a new, detailed insight into what makes up the lunar soil. And whilst scientists were unsurprised by the presence of iron, titanium, aluminium and calcium in the rocks, they were stunned to note a much higher concentration of sulphur than expected. The discovery is significant for a number of reasons. Most significantly, perhaps, because the sulphur could be used to help create a human base on the Moon. As Jeffrey Gillis-Davis, a planetary scientist, pointed out in a piece for Science Alert: "Astronauts and robots could travel from the south pole base to collect, process, store and use naturally occurring materials like sulfur on the Moon – a concept called in-situ resource utilization. "In-situ resource utilization means fewer trips back to Earth to get supplies and more time and energy spent exploring. Using sulfur as a resource, astronauts could build solar cells and batteries that use sulfur, mix up sulfur-based fertilizer and make sulfur-based concrete for construction." Gillis-Davis went on to explain that sulfur-based concrete has a number of advantages over the more common variety used in building, pointing out that it "hardens and becomes strong within hours rather than weeks, and it's more resistant to wear". "It also doesn't require water in the mixture, so astronauts could save their valuable water for drinking, crafting breathable oxygen and making rocket fuel," he added. The presence of sulphur near the Moon's south pole also suggests that highland soils at the lunar poles could have very different compositions to highland soils at the lunar equatorial regions. This would have key implications for our understanding of how the Moon works as a geological system, given that sulfur mainly comes from volcanic activity. Still, there's plenty of work to be done. And while this is all just one small step in Chandrayaan-3's mission, it could mean a great leap in how we view our dear celestial companion.
