Cosmology

A theoretical study suggests that dying stars might create new universes powered by dark energy, forming gravastars instead of black holes.

A new model, the Cosmological Hart-Tipler Conjecture, suggests advanced extraterrestrial life is extremely rare, incorporating cosmic expansion into the analysis.

A new philosophical analysis challenges the "block universe" model of spacetime, suggesting that a fundamental misunderstanding of existence versus occurrence has led to confusion in modern physics.

Astronomers have captured the clearest direct image of a cosmic web filament, revealing a three-million-light-year strand connecting two ancient galaxies.

A new survey of physicists reveals a lack of consensus on fundamental questions in cosmology, including the Standard Model and the nature of dark matter.

University students built a dark matter detector to search for axions, establishing new experimental limits and demonstrating the value of small-scale research.

New research on ultra-faint dwarf galaxies suggests they hold crucial information about the early universe's conditions and star formation.
