A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing intricate details. As you might imagine, mapping the universe on the largest of ...

As we delve deeper into the cosmos, artificial intelligence (AI) is becoming an indispensable tool, enabling scientists to simulate universes on a scale never seen before. This novel approach is not ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

"It is larger than the size of most anything to which it might be compared." The universe's largest structure, the Hercules-Corona Borealis Great Wall, was already a challenge to explain with models ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first predicted by Albert Einstein back in 1915, could have given rise to cosmic ...

The universe may have been born out of nothing, with an "anti-universe" twin where time runs in the opposite direction—rather than exploding from an infinitely small and dense point, or "singularity." ...

Many people wonder: if the universe is expanding, is there a point in space that serves as the “centre”? It seems intuitive to ask, how can something expand if there’s no specific starting point? The ...

An international team has discovered a giant spiral disk galaxy in the early cosmos which is three times larger than similar galaxies of the same epoch. Galactic disks are flat, rotating structures ...
