Stars, Cells, and God | Life on K2-18b? and Galaxy Formation Models

Join Hugh Ross and Jeff Zweerink as they discuss new discoveries taking place at the frontiers of science that have theological and philosophical implications, including the reality of God’s existence. Life on K2-18b? Two months ago the Internet blew up with articles and blogs announcing that astronomers had discovered molecules in the atmosphere of exoplanet K2-18b that only living organisms can produce. Those biosignature molecules were dimethyl sulfide and chloromethane. While there is no doubt that methane was detected in K2-18b’s atmosphere and carbon dioxide likely detected, the detections of dimethyl sulfide and chloromethane were marginal at best. Furthermore, astronomers have detected chloromethane in a comet and an interstellar cloud where it is well established that life and life chemistry is impossible, and they found abiotic pathways for the production of dimethyl sulfide. The Internet articles overlooked the physical characteristics of K2-18b and its host star that categorically rule out any possibility of physical life on the planet.

Some astronomers have even used this discrepancy to argue against big bang cosmology. A recent paper provides strong evidence for the formation of spiral-type galaxies forming within the first billion years of the universe (where most models predict much longer formation times). We discuss the importance of this data and the implications for how galaxy formation models will change—particularly becoming more complex. Additionally, we expect that this complexity will reveal even more evidence for design in the universe than is now known.
