Abstract
The faint young sun (FYS) was introduced as a paradox by prominent astronomer Carl Sagan dan George Mullen. This paradox posits that the luminosity of the sun 4.6 billion years ago (when it came into existence) was less than 30% of its current luminosity. The variation in solar radiance might have facilitated the Origin of Life (OOL) on Earth by influencing prebiotic chemistry, especially in the formation of prebiotic polyester. Polyester, synthesized from alpha hydroxy acids(ɑHAs), serves as a model studied as a framework that facilitates OOL. Studies indicate that polyester gels can form from dehydration reactions of ɑHAs in wet-dry cycles, potentially initiating prebiotic life. Moreover, various investigations have demonstrated that ultraviolet UV light has been known to initiate prebiotic chemical reactions, as well as produce polyester. However, experiments have been done, but none has truly explored broadband light from the FYS. Furthermore, prebiotic polymerization induced by FYS has not been shown. In this paper, we will discuss about FYS, some research conducted regarding prebiotic reactions induced by UV light, and the prospects of how FYS’ broadband light might be beneficial for prebiotic polymerization involving polyester.
