How An Extreme New Star Could Change All Cosmology

The video explores the discovery of a peculiar white dwarf star, ZT FJ19O1+1458, which challenges existing theories about white dwarf formation. This star, discovered at the Zwicki Transient Facility, exhibits unusual properties such as rapid rotation and strong magnetic fields. Advanced observations suggest it may have formed from a white dwarf collision, raising questions about the nature of Type 1A supernovae and dark energy calculations. The video discusses the potential future of this star, including the possibility of it becoming a neutron star or exploding as a supernova.
