Biggest-ever simulation of the universe could finally explain how we got here
Biggest-ever simulation of the universe could finally explain how we got here
It’s one of the biggest questions humans have asked themselves since the dawn of time, but we might be closer than ever to understanding how the universe developed the way it did and we all came to be here. Computer simulations are happening all the time in the modern world, but a new study is attempting to simulate the entire universe in an effort to understand conditions in the far reaches of the past. Full-hydro Large-scale structure simulations with All-sky Mapping for the Interpretation of Next Generation Observations (or FLAMINGO for short), are being run out of the UK. The simulations are taking place at the DiRAC facility and they’re being launched with the ultimate aim of tracking how everything evolved to the stage they’re at now within the universe. The sheer scale of it is almost impossible to grasp, but the biggest of the simulations features a staggering 300 billion particles and has the mass of a small galaxy. One of the most significant parts of the research comes in the third and final paper showcasing the research and focuses on a factor known as sigma 8 tension. This tension is based on calculations of the cosmic microwave background, which is the microwave radiation that came just after the Big Bang. Out of their research, the experts involved have learned that normal matter and neutrinos are both required when it comes to predicting things accurately through the simulations. "Although the dark matter dominates gravity, the contribution of ordinary matter can no longer be neglected, since that contribution could be similar to the deviations between the models and the observations,” research leader and astronomer Joop Schaye of Leiden University said. Simulations that include normal matter as well as dark matter are far more complex, given how complicated dark matter’s interactions with the universe are. Despite this, scientists have already begun to analyse the very formations of the universe across dark matter, normal matter and neutrinos. "The effect of galactic winds was calibrated using machine learning, by comparing the predictions of lots of different simulations of relatively small volumes with the observed masses of galaxies and the distribution of gas in clusters of galaxies," said astronomer Roi Kugel of Leiden University. The research for the three papers, published in the Monthly Notices of the Royal Astronomical Society, was undertaken partly thanks to a new code, as astronomer Matthieu Schaller of Leiden University explains. "To make this simulation possible, we developed a new code, SWIFT, which efficiently distributes the computational work over 30 thousand CPUs.” Sign up for our free Indy100 weekly newsletter How to join the indy100's free WhatsApp channel Have your say in our news democracy.

The Rolling Stones and Skechers launch shoe collaboration with iconic tongue logo
The Rolling Stones and Skechers launch shoe collaboration with iconic tongue logo
The Rolling Stones and footwear brand Skechers have teamed up to launch a collection of trainers for men and women. The collaboration with the legendary British rock band features a range of limited edition designs, all featuring the iconic lips and tongue logo designed in 1970 by English artist John Pasche. Produced in partnership with Bravado, Universal Music Group’s merchandise and brand management company, the Skechers X The Rolling Stones collection comprises of three styles: the modern Skechers Uno, a canvas slip-on, and lug and cup sole designs. The canvas slip-ons are made from light-wash blue denim, with the tongue and lip logo on the tops of the shoes. Meanwhile, the other two designs come in a black-and-white, as well as a red-and-white colourway, with the logo placed either on the side of towards the back of the trainers. The collection will launch exclusively at the RS No 9 Carnaby, The Rolling Stones’ flagship merchandise store in London today (Thursday 15 June), followed by stores across the UK and the EU on 22 June. The Rolling Stones said in a statement: “We love partnering with brands that offer great product and giving our fans something new they can enjoy.” Michael Greenberg, president of Skechers, added: “For six decades, the Stones have endured like no other – rebelling, conquering and being listened to by billions. Nearly every adult on this planet knows their iconic logo.” Skechers recently released a collaboration with Doja Cat, which comprised of the Skechers Uno trainers in different colours, such as neon pink, neon green and bright purple. The American footwear company has also previously collaborated with musicians including Ringo Starr, Britney Spears, Christina Aguilera, and Snoop Dogg.
