Chemical Signatures of ET? | Timescape Cosmology

Join astrophysicists Hugh Ross and Jeff Zweerink as they discuss new discoveries with theological and philosophical implications pointing to the reality of God’s existence.

Dimethyl sulfide in a planet’s atmosphere has been widely cited as an unambiguous signature of life on the planet. However, the discovery of dimethyl sulfide in a comet, in the interstellar medium, and in laboratory photochemical experiments shows nonbiological pathways for the manufacture of dimethyl sulfide and other organosulfurs. Thus, the James Webb Space Telescope’s discovery of such organic compounds on exoplanets can’t prove life exists on another planet.

The seeds of big bang cosmology were planted nearly 100 years ago, and it stands as the reigning cosmology model for the last 60–70 years. What many people may not realize is that the mathematical foundation for the big bang rests on an approximation needed to solve Einstein’s equations of general relativity. Over the last 20 years, a growing group of scientists have argued that more accurate solutions that don’t utilize the approximation provide a better model of the universe while simultaneously removing the need for dark energy. We describe the basics of this new model and discuss the apologetics implications.
