The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer ...

Understanding the early universe is a foundational goal in space science. We're driven to understand nature and how it evolved from a super-heated plasma after the Big Bang to the structured cosmos we ...

FLAMINGO simulation maps the universe but reveals a puzzling mismatch: galaxies cluster less than theory predicts.

Recent observational breakthroughs are beginning to challenge the long-standing view of dark energy as unchanging. Data from the Dark Energy Spectroscopic Instrument ( DESI ), an advanced survey ...

Another batch of the ‘impossible’ galaxies turned out not to be standard galaxies at all, but a new type of object that ...

The mystery of how the first quasars in the universe formed—something that has baffled scientists for nearly 20 years—has now been solved by a team of astrophysicists whose findings are published in ...

Cosmic dawn galaxies seen by JWST reveal hidden clues about dark matter and keep rival theories about its true nature alive.

New research from UBC Okanagan mathematically demonstrates that the universe cannot be simulated. Using Gödel’s incompleteness theorem, scientists found that reality requires “non-algorithmic ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. When you ...

NASA’s Roman Space Telescope is set to embark on a deep-sky survey that could capture nearly 100,000 cosmic explosions, shedding light on everything from dark energy to black hole physics. Its ...
