The Best in Science News and Amazing Breakthroughs
How did we get here? Not just we humans, scrabbling about on a pale blue dot, hurtling around a star, hurtling around a supermassive, hurtling through the local cluster. But how did the dot get here, and the star, and the black hole, and the cluster?That's it, really, the question of questions. And, with the largest project of its kind to date, astronomers are attempting to find answers – by conducting computer simulations of the entire Universe.These simulations are intense.
That means normal matter: the stars; the galaxies; all the stuff we could touch ;The largest of these simulations has 300 billion particles with the mass of the small galaxy, in a cubic volume of space with edges of 10 billion light-years. "To make this simulation possible, we developed a new code, SWIFT, which efficiently distributes the computational work over 30 thousand CPUs,"So far, they have not managed to resolve the tension – that would be huge news for cosmology – but they have something about conducting simulations: both normal matter andA simulation that includes normal matter is more difficult to run.
The team has not yet made its FLAMINGO data available to the public, because it is several petabytes in size. Anyone who is interested is encouraged to lodge a polite enquiry
