A comprehensive exploration of competing cosmological theories examines the Big Bang model alongside alternative explanations for the universe's origins and expansion.

For over a century, the Big Bang theory has dominated our understanding of cosmic origins, describing the universe's expansion from an extremely dense state rather than an explosion in space. Scientists rely on the Cosmic Microwave Background and 3D galaxy maps from instruments like DESI to study early universe conditions. While cosmic inflation theory explains rapid initial expansion, researchers from the University of Portsmouth propose an alternative "bounce universe" model, suggesting our cosmos emerged from matter collapse in a larger universe forming a massive black hole, where quantum effects prevented singularity and triggered expansion.

• The Big Bang describes space expansion, not an explosion, with cosmic inflation theory explaining ultrafast early growth
• Portsmouth researchers propose a bounce universe theory where quantum effects in a collapsing black hole triggered expansion
• ESA Euclid and ARRAKIHS missions will provide precise data to test competing cosmological models
• Both theories must explain observed patterns in the Cosmic Microwave Background and galaxy distributions
