Join astrophysicists Hugh Ross and Jeff Zweerink as they discuss new discoveries with theological and philosophical implications pointing to the existence of God.
Hugh explains that the Dark Energy Spectroscopic Instrument (DESI) Collaboration has released redshift and position measurements on 3,855,000 galaxies and 857,000 quasars in the redshift range 0.1–2.1. Analysis of this database shows that gravity alternatives to general relativity on large cosmic size scales are negligible and provides stronger evidence for a time-varying dark energy equation of state. The analysis also yields the best measure to date of the cosmic matter density, thereby affirming a feature of cosmic creation. Jeff discusses how scientists over the past 10–15 years have discovered a tension between measurements of the Hubble constant from the early universe compared to the late universe. If found to be a real discrepancy, such a tension could point to new physics and a greater understanding of the development of the universe. A new study with data from James Webb Space Telescope (JWST) affirms the validity of the late Hubble constant measurement, strengthening the case for a legitimate discrepancy.
