A huge bubble of galaxies that is one billion lightyears across could be a remnant of the ripples caused by the Big Bang, according to astronomers who have mapped the structure. The structure, named Hoʻoleilana by University of Hawaii scientists, is thought to have been caused by so-called Baryon Acoustic Oscillations (BAOs). These were ripples in the particles of the early Universe in the period following the Big Bang, when planets, solar systems and galaxies were not yet fully formed. As the ripples went outward, they created areas of density in the particles, causing bubble-like structures in which galaxies eventually coalesced. Until now, the BAOs were just a prediction – part of the wider Big Bang theory. No specific structures in the Universe had been found which mimicked their patterns. But Hoʻoleilana fits the description of these huge cosmic bubbles perfectly, according to Brent Tully, who led the study at the University of Hawaii’s Institute for Astronomy. “We were not looking for it. It is so huge that it spills to the edges of the sector of the sky that we were analyzing,” he said. “As an enhancement in the density of galaxies it is a much stronger feature than expected. The very large diameter of 1bn light years is beyond theoretical expectations. “If its formation and evolution are in accordance with theory, this BAO is closer than anticipated, implying a high value for the expansion rate of the universe.” The bubble is absolutely huge. It is made up of several superclusters, structures which themselves are thought to be among the Universe’s largest arrangements of matter. This includes the Hercules Supercluster, the Corona Borealis Supercluster and the Sloan Great Wall. All of these structures contain thousands of galaxies. In the middle of Hoʻoleilana sits the Bootes Supercluster and the Bootes Void, an immense space of nothingness which is an incredible 330m lightyears across. Daniel Pomarede, from the CEA Paris-Saclay University, who contributed to the research, said: “It was an amazing process to construct this map and see how the giant shell structure of Ho’oleilana is composed of elements that were identified in the past as being themselves some of the largest structures of the universe.” The research was published on 5 September in The Astrophysical Journal.

Google is set to begin deleting millions of Gmail, Drive and Photos accounts next month as part of a major update to the platform. The purge will impact all personal Google accounts that have been left dormant for at least two years, with emails, documents, spreadsheets, calendar appointments, photos and videos all permanently deleted. The policy was introduced earlier this year but is set to come into effect in December 2023. “We are updating our inactivity policy for Google Accounts to two years across our products,” Ruth Kricheli, Google’s vice president of product management, wrote in a blog post in May. “This update aligns our policy with industry standards around retention and account deletion and also limits the amount of time Google retains your unused personal information.” The move is aimed at protecting active Google users from security threats like phishing scams and account hijacking. Old accounts that have not been used for years are typically at risk from hackers as they may use the same passwords that have been compromised in other security breaches, which are easily available on the dark web. Any account at risk of deletion will receive “multiple notifications” before any action is taken, Google said, including to any associated recovery email addresses. The tech giant has already begun sending emails to those affected, telling users it is “to protect your private information and prevent any unauthorised access to your account even if you’re no longer using our services”. Losing access to a Gmail account could also potentially prevent people from using other online platforms and services that are associated with that email address, even if they are not related to Google. In order to keep an account active and avoid being deleted, Google users are advised to open or send an email, use Google Drive, download an app on the Google Play Store, or simply make a Google Search while logged in to the account. Any account that has posted a video to YouTube will also not be impacted, regardless of when it was last active.

Archaeologists in Turkey are slowly unravelling the secrets of a previously unknown ancient language. And among them are revelations that long-forgotten civilisations used language to promote multiculturalism and political stability. The ancient clay tablets unearthed from archaeologists, in the ancient capital of the Hittite Empire at Hattusa, were recently found to contain the previously unknown language. Researchers had dusted off nearly 30,000 unique tablets at the scene – a UNESCO World Heritage Site – with most written in Hittite, and a few in the brand new language. The ongoing excavations have since revealed that the imperial civil service had whole departments whose job it was to research their subject peoples’ religions. Back in the second millennium BC, Hittite leaders told their officials to record religious ceremonies and other traditions of subject peoples by writing them in their respective local languages. The idea was that the traditions would be preserved and incorporated into the wider empire, in what appears to be a push towards multiculturalism. The fact that multiculturalism was such a prominent part of Bronze Age culture certainly has resonances in the modern day, where debates around immigration and multiculturalism continue to be a hot topic. So far, experts have found at least five subject ethnic groups who have had the treatment, with the latest example unearthed two months ago. It was written in a previously unknown Middle Eastern language that had been lost for up to 3,000 years. The language is being called Kalasmaic, because it would have been spoken by a subject people in an area called Kalasma in the northwest of the empire. And while only five minority languages have so far been found on the Bronze Age tablets, the reality is that there were probably at least 30, archaeologists say. Daniel Schwemer, a Wurzburg University professor who is leading the investigation into the newly discovered texts, said: “Bronze Age Middle Eastern history is only partly understood – and discovering additional clay tablet documents is helping scholars to substantially increase our knowledge.” How to join the indy100's free WhatsApp channel Sign up to our free indy100 weekly newsletter Have your say in our news democracy.
