00:00The largest ever simulation of the universe has just been released.

00:04Is this real life or a simulation?

00:07Well, the jury's out on that one.

00:09However, simulations are created by humans frequently.

00:13In fact, the Euclid Consortium,

00:15the international group managing the European Space Agency's Euclid Space Telescope,

00:20just published the world's most extensive simulation of the universe.

00:25It maps an astonishing 3.4 billion galaxies

00:28and tracks the gravitational interactions of more than 4 trillion particles.

00:33Called Flagship 2,

00:35the simulation draws from an algorithm designed by astrophysicist Joachim Stadel

00:39of the University of Zurich, Juzic.

00:42In 2019, Stadel used the supercomputer Pizdaint,

00:46then the third most powerful supercomputer in the world to run the calculation,

00:51ultimately creating an exceptionally detailed virtual model of the universe.

00:55Astrophysicist Julian Adamek of Juzic, a collaborator on the project,

01:00said in a statement that these simulations are essential for preparing the analysis of Euclid's data.

01:06Since 2023, the Euclid Space Telescope has been mapping billions of galaxies across the universe,

01:12studying the distribution of dark energy and dark matter.

01:16The spacecraft will eventually scan about one-third of the night sky.

01:21Euclid generates a large amount of data due to the project's scope,

01:25and simulations like Flagship 2 aid in reducing processing times.

01:29Although the team anticipates that Euclid's observations will closely match the simulation's predictions,

01:35there may be unexpected outcomes.

01:37Flagship 2 runs on the standard cosmological model,

01:41which is what we currently know about the universe's composition.

01:44But missions like Euclid are designed to challenge our current knowledge.

01:48We already see indications of cracks in the standard model.

01:52The team is especially excited to investigate the mystery of dark energy,

01:57the driving force behind the universe's expansion.

02:00As it stands in the standard cosmological model, dark energy is simply a constant.

02:05But Euclid's observations, which will look up to 10 billion years in the past,

02:10might reveal different characteristics.

02:12We can see how the universe expanded at that time

02:15and measure whether this constant really remained constant.

02:18Is that constant?
