Arp's Anomalies

Arp’s anomalies are unexpected observations about galaxies and quasars that challenge traditional ideas about how the universe expands. Specifically, astronomer Hal Arp noticed that some galaxies and quasars appear closely connected or aligned in ways that suggest they might be physically related, despite having different distances from Earth. These observations contradict the standard view that such objects are only coincidentally aligned and at vastly different distances. Arp’s work raises questions about the nature of these objects and the expansion of the universe, prompting discussions about alternative explanations for their relationships beyond current cosmological models.
