Galaxies and Cosmology
3 reportsGalaxies and Cosmology is investigated with imaging, spectroscopy, timing, surveys, and physical models suited to the object or signal. Researchers test interpretations with gravitational lensing, large scale structure, and galaxy redshift, while incomplete records, model assumptions, and measurement limits constrain certainty.
Star formation history, galaxy formation, and dark matter halos provide separate checks. Together they examine how galaxies form and evolve and how dark matter shapes galaxies, showing how sparse measurements or incomplete records limit certainty.

Webb Telescope Reveals Merging Young Galaxy Cluster 4.4 Billion Light-Years Away
NASA's James Webb Space Telescope has imaged the galaxy cluster MACS J0553.4-3342 as it appeared 4.4 billion years ago, capturing two massive sub-clusters in the process of merging and highlighting the gravitational effects shaping distant galaxies
Black Hole Thermodynamics Updated Beyond Hawking's Original Theory
Physicists have proposed a new framework for describing black hole energy loss, extending thermodynamic laws to dynamic black holes and addressing a key limitation in Stephen Hawking's classic model
Dark Matter Theory Links Hidden Dimensions to Cosmic Structure
A new theoretical study explores whether dark matter's elusive nature could be explained by its interaction with a hidden fifth dimension, offering a possible connection between two of physics' most persistent mysteries
