(Phys.org)—Researchers working out of the University of Copenhagen have published a paper in the journal Science in which they claim that a new method of dating chondrules and calcium-aluminum–rich inclusions (CAIs) is more accurate than previous methods. Their dating method produces results that contradict earlier findings that have suggested that chondrules formed up to 2 million years later than CAIs; instead they say, the two materials found in meteorites formed at roughly the same time.
