LONDON & KRAKOW, Poland--(BUSINESS WIRE)--Jun 15, 2023--

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.

Meta is revamping Facebook’s logo to a darker blue with a few small tweaks to create what it claims is a “bolder, electric and everlasting” design. The “subtle” logo change – which at first glance may seem barely noticeable – incorporates a “more confident expression of Facebook’s core blue color,” the social media company said in a blog post. Facebook says the logo change to the lowercase “f” is more visually accessible in the platform’s app with “stronger contrast for the ’f’ to stand apart”. “We wanted to ensure that the refreshed logo felt familiar, yet dynamic, polished and elegant in execution. These subtle, but significant changes allowed us to achieve optical balance with a sense of forward movement.” Dave N, director of design at Facebook said. The social media giant highlighted three “key drivers” behind the evolution of its logo, including a push to “elevate the most iconic elements” of the brand, and to create “an expansive set of colors” anchored in blue. Over the years, the social media platform’s logo has undergone a number of changes, starting from one that had square boundaries to the current circular design. The new logo, the company says, uses its custom typeface – Facebook Sans – and a redesigned wordmark and logo to “create a consistent treatment and improve overall legibility.” The new design has led to some being left puzzled on social media. Some users, however, described the design changes in a little more detail. Facebook says it has also developed a new colour palette with a new set of hues, tones and contrast ratios. “The deep tonal range of secondary blues allows for flexibility while providing balance as a single expression of our brand identity,” the company said. It said more changes to the platform’s “reactions, typography and iconography” are to be rolled out in the future. “All of these refinements will create a more consistent, personal and seamless experience for the billions of people who interact with Facebook daily,” the company said. Meta likely has more changes planned for the brand’s design in the coming days, with the company describing the latest tweaks on Wednesday’s blog as “the first phase of a refreshed identity system” for the app. Read More Meta’s encryption plans will create ‘safe haven’ for paedophiles, Braverman says Elon Musk warns of ‘civilisational risk’ posed by AI at historic gathering of tech giant chiefs Twitter rival Threads’ launch of much-anticipated feature did little to attract more users, data suggests What is ‘Rumble’, where Russell Brand is posting videos?
