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.
Before the First Stars
A team of astronomers have used the James Webb Space Telescope (JWST) “to boldly go where no man has gone before”: to observe and measure the composition of gas clouds before any stars formed. The JWST’s primary mission is to explore the cosmic dawn—the first billion years of cosmic history. Astronomers took a high-resolution spectrum of a giant gas cloud in the halo of GN-z11, a bright galaxy 13.38 billion light-years away, corresponding to only 410 million years after the big bang creation event. The only elements found in the gas cloud’s spectrum were hydrogen and helium. This is the first time astronomers detected an object in the universe where no elements heavier than helium exist. This discovery affirms a major prediction of the biblically predicted big bang creation model: that before stars formed, the elemental composition of the universe, by mass, will be 75.33% hydrogen, 24.67% helium, and a trace amount of lithium. The level of ionization in the gas cloud revealed that the stars in GN-z11’s core must all be in the range of 50–1,000 times the Sun’s mass. This mass range explains why astronomers observe many bright galaxies and several supermassive black holes in the cosmic dawn. All these discoveries provide yet more evidence that the more we learn about the universe, the more evidence we accumulate that a God beyond space and time created and exquisitely designed the universe so that at the just-right time and location, humans could live and thrive.
The Universe: 28 GYr Old?
Recent images from the James Webb Space Telescope (JWST) found galaxies that, given their age, appeared far larger and more complex than expected. In more lay-level arenas, this discovery was used to cast doubt on the standard big bang cosmological model. However, this discovery generated quite a bit of excitement in the scientific community because it revealed a fun problem to investigate. Consequently, astronomers have invested much effort trying to understand how to explain these large, complex galaxies. An author of a recent paper attempts to understand these galaxies by modifying how light propagates through the universe and by having some fundamental constants change over time. A careful analysis of this latter approach shows how standard big bang cosmology (with dark energy and dark matter) can give a robust explanation of the universe—and provide evidence for the God of the Bible.
