Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Physicists have spent decades arguing over whether our universe is a fundamental reality or a kind of cosmic software, and ...

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

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

If true (and it’s a pretty big “if”), Vopson’s new gravitational study would shake the foundations of the currently accepted view of the universe. In his paper, Vopson writes that his new work could ...

The dynamical dance of physics can entrance — as the latest supercomputer models of the cosmos demonstrate. Dubbed FLAMINGO, the set of simulations captures the emergence of the structure of the ...

Scientists made a twin version of our universe, showing the evolution of all forms of matter and energy, in the biggest cosmological computer simulation to date. When you purchase through links on our ...

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 ...

Since the gravitational waves predicted by Einstein were first detected in 2015, astrophysicists have been pondering the gravitational wave background—the cumulative undulations of these spacetime ...
