How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has long been a puzzle, but a University of Arizona-led team of scientists is one step closer to finding answers, thanks to supercomputer simulations. Observing real galaxies in space can only provide snapshots in time, so researchers who study how galaxies evolve over billions of years need to use computer simulations. Traditionally, astronomers have used simulations to invent theories of galaxy formation and test them, but they have had to proceed one galaxy at a time. Peter Behroozi of the university's Steward Observatory and colleagues overcame this hurdle by generating millions of different universes on a supercomputer, each according to different physical theories for how galaxies form. The findings challenge fundamental ideas about the role dark matter plays in galaxy formation, the evolution of galaxies over time and the birth of stars. The study is the first to create self-consistent universes that are exact replicas of the real ones -- computer simulations that each represent a sizeable chunk of the actual cosmos, containing 12 million galaxies and spanning the time from 400 million years after the Big Bang to the present day. The results from the "UniverseMachine," as the authors call their approach, have helped resolve the long-standing paradox of why galaxies cease to form new stars even when they retain plenty of hydrogen gas, the raw material from which stars are forged. The research is partially funded by NSF's Division of Physics through grants to UC Santa Barbara's Kavli Institute for Theoretical Physics and the Aspen Center for Physics.

I’m not entirely sure who the Samsung Galaxy Note is aimed at, but as somebody who gets to observe from the sidelines, this is one fun, functional and loveable device — although it comes at an out of contract price of around £450-500 upwards, give or take. The biggest talking point of the Galaxy Note is its [...]

Matt Egan is back in the hosting chair to chat with producer Chris about the Samsung Galaxy Note 7 and how we feel about phablets. Techworld.com editor Charlotte Jee comes in to explain what is going on at the GDS (government digital service) and why we should care (13:00). Then online editor at Techworld.com Scott Carey chats Instagram stories, why it is a blatant rip off of Snapchat stories and how the social media giant can get away with being so brazen (22:00).

Matt Egan hosts as we delve into the tech headlines of the week. Senior Staff Writer at PC Advisor Henry Burrell talks the gang through the latest on Samsung's upcoming smartphone and why it's been delayed, plus another brand comes back from the brink. Online Editor at Techworld Tamlin Magee then explores the strange but true story of Silicon Valley billionaires buying private islands with underground bunkers in case everything really does go Pete Tong. Finally Staff Writer at Macworld UK and PC Advisor Dominic Preston talks us through the frights of the latest Resident Evil game while everyone agrees they can be more terrifying than most horror films.

5G tablets are on the way, and Samsung's Galaxy Tab S6 could be repackaged as one of the first. The South Korean company accidentally listed the 5G-ready model on its website. Now, it's only a matter of time before the Galaxy Tab S6 5G goes official.

The Samsung Galaxy Note 10+ is a big, powerful phone that's good for artists and note-takers.

Samsung will announce the next-generation foldable phone later this month; however, a newly-leaked hands-on video reveals exactly how its Galaxy Z Flip will perform in the real world.

The new foldable phone from Pablo Escobar's brother is a Samsung Galaxy Fold with no changes to the software, according to a YouTuber and a journalist who obtained the products amid consumer worries the business is a scam.

The Samsung Galaxy Z Flip is the first folding phone to really work, but it's still a costly and potentially fragile fashion object rather than a mainstream hit.

The Galaxy S20 Ultra has the potential to become the best phone you can buy, but it's not worth $1,400 until Samsung fixes some bugs.

The Samsung Galaxy S20 is the most manageable of the S20 lineup in terms of size and price, but it may get left behind with future 5G upgrades.
