Time ran five times slower in the early universe, new study finds
Time ran five times slower in the early universe, new study finds
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.

Boy wins solid gold Prime bottle worth a staggering £400k from KSI and Logan Paul
Boy wins solid gold Prime bottle worth a staggering £400k from KSI and Logan Paul
A young boy has won a solid gold Prime bottle worth an incredible $400k after successfully entering a competition held by KSI and Logan Paul. The young lad won after successfully guessing the code to a special locked bottle of the drink in London. It comes after KSI and Paul launched a giveaway for one of two gold bars that had been crafted into the shape of their energy drink – one in London and one in New York. Announcing the competition on Instagram, the pair said: "The golden Prime will be encased in bulletproof glass. "To get to it you must correctly guess a six-digit code. Each person only has one guess and only 20 seconds to make that guess.” They added: "If the code is not guessed correctly within 48 hours, the torches inside the case will ignite. "And the gold prime bottle will be incinerated completely - worth absolutely nothing.” They also explained that the items had been made by the former NASA engineer Mark Rober”. The competition was launched to mark the sale of one billion Prime bottles across the world, as the pair celebrated the remarkable success of the energy drink. Thousands tried across both locations, but it was a young load in a Pinewood FC shirt that managed to guess the right code. The winning moment saw him type in the right numbers, setting off the confetti and smiling as he held the prize. The other prize in New York was subsequently melted down, ensuring there was only one winner. The pair then released a statement, saying: "We do everything BIG. Since we created PRIME, we’ve made our own blueprint when it came to marketing, scaling, and building the brand. "In a short period of time, we’ve become the fastest-growing beverage company in history, selling our one-billionth bottle in just year two,” they added. "We’re confident our fans will be pleasantly surprised when they visit our celebratory Gold Stores and see what a unique experience our team has built."
