Laser star model of quasars

The laser star hypothesis is a hypothesis put forward by the physicist Y. P. Varshni in 1973 in response to several developments in astrophysical and earth-based research, and his belief that the existing body of work on quasars, or "quasi stellar objects," suffered fundamental difficulties. It states that quasars are hot stars with strong stellar winds which are producing natural lasing. This model is contradicted by the current astrophysical science community understanding that quasars are distant active galactic nuclei.
