摘要: We hypothesize that cosmic string loops are the seeds about which globular clusters accrete. Fixing tension by demanding peak in distribution of masses objects accreting onto agrees with observed mass our Milky Way galaxy, we then compute expected number density and function clusters, compare observations. Our hypothesis naturally explains why oldest most dense a they found halo galaxy.
