Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists can't explain the Hubble tension just by changing the expansion rate in the late universe – this whole class of solutions falls short. When you purchase through links on our site, we may ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Researchers in Germany argue that a modified theory of gravity could explain universal expansion, removing dark energy from ...

The Big Bang theory has provided the most widely accepted basis of our understanding of the universe since it was first proposed by Georges Lemaitre in 1927. In short, it posits that all the matter in ...

NASA/CXC/Univ. of Bonn/K. Migkas et al. Less than a second after the Big Bang, the universe suddenly blew up from nothing to a hot, dense sea of neutrons and electrons stretching across billions of ...

Research by the Atacama Cosmology Telescope collaboration has culminated in a groundbreaking new image that reveals the most detailed map of dark matter distributed across a quarter of the entire sky, ...

Aug. 29 (UPI) --Early universe observations by the James Webb Space Telescope cannot be explained by current cosmological models. These models estimate the universe to be 13.8 billion years in age, ...
