A new discovery of a low-mass star stands to put big bang creation on even more solid footing. In the biblically predicted big bang creation model,1 long before any stars exist, the universe contains only three elements: hydrogen, helium, and a trace amount of lithium.2 Thus, in big bang cosmology the universe’s firstborn stars will be devoid of elements heavier than lithium.

A remaining challenge to the big bang creation model is that astronomers have yet to detect a star containing no elements heavier than lithium. Several atheists and all young-earth creationist scientists refer to this lack of evidence as proof that the big bang model has failed. In Jonathan Sarfati’s book, Refuting Compromise, he writes,
“The total absence of these stars counts as a falsified prediction of big bang cosmology.”3

Big bang proponents give little credence to this challenge since no presently available telescope is powerful enough to detect a star devoid of elements heavier than lithium. In big bang cosmology the first stars would have formed 13.6 billion years ago.4 Thus, to observe these stars in their initial state we must measure the spectra of individual stars 13.6 billion light-years away. No telescope yet exists to measure a star’s spectrum at that distance.

Current telescopes are powerful enough, however, to detect low-mass firstborn stars well past their initial state. Unlike high-mass stars that burn out in a few million years or less, low-mass stars continue to shine for billions of years. Hence, it is possible to observe low-mass firstborn stars at relatively nearby distances.

A low-mass firstborn star that is several billion years old, though, will accrete over its several-billion-year history a small quantity of heavy elements from the interstellar medium. The ashes from the exploded remains of the supergiant firstborn stars pollute the interstellar medium.

In regions where the stellar density is high, the pollution can be so great as to make it difficult for astronomers to detect the difference between a polluted firstborn star and a relatively unpolluted second-generation star. However, for a low-mass firstborn star residing in a region where the density of stars is very low, the pollution from the interstellar medium will be so extremely low that there will be no doubt that astronomers are observing an old firstborn star rather than any kind of second-generation star.

There are no nearby regions characterized by a very low stellar density. Consequently, astronomers have discovered only a single handful of stars possessing an extremely low abundance of elements heavier than lithium.

Calculations performed by Japanese astronomers5 showed that an old firstborn star in a region of low stellar density can accumulate up to 1/100,000th as much iron per unit mass as the Sun, while it would be impossible for any kind of second-generation star to possess so little iron. The most iron-poor star discovered so far is SMSS J0313-6708. It possesses less than 3 x 10-8 as much iron as the Sun.6 This star, however, possesses measurable abundances of both carbon and magnesium. That measurable amount of carbon and magnesium led two teams of astronomers to conclude that SMSS J0313-6708 is a low-mass firstborn star that was heavily polluted by the iron-poor ejecta from a single supernova eruption of a nearby massive firstborn star.7

Now, a team of four astronomers in Spain has determined that the recently discovered star, J0023+0307, possesses both an extremely low abundance of iron and an extremely low abundance of carbon.8 J0023+0307’s iron abundance is less than 2.5 x 10-7 as much as the Sun’s and its carbon abundance less than 1,300 times as much as SMSS J0313-6708’s.

The four astronomers point out that it is likely that J0023+0307 may possess a carbon-to-iron ratio as low as the Sun’s and perhaps even lower. If J0023+0307’s carbon-to-iron ratio is the same as the Sun’s, then its total quantity of elements heavier than lithium compared to the Sun’s is less than 2.5 x 10-7. Such a low abundance of elements heavier than lithium would make J0023+0307 the most metal-poor (in astronomy, any element heavier than helium is a metal) star known. In fact, it makes J0023+0307 at least 40 times more metal-poor than any other known star.

The team of four close their research paper by appealing to other astronomers to take high-resolution spectra of J0023+0307 on the world’s largest optical telescopes. Such spectra potentially will reveal the detailed nature of J0023+0307’s abundance of elements heavier than lithium rather than simply provide strong upper limits. However, the limits the four astronomers established already leave no doubt that J0023+0307 is a firstborn star that was very lightly polluted by the interstellar medium. Hence, the so-called challenge to the biblically predicted big bang creation model has been resolved in its favor.

About The Author

Dr. Hugh Ross

Reasons to Believe emerged from my passion to research, develop, and proclaim the most powerful new reasons to believe in Christ as Creator, Lord, and Savior and to use those new reasons to reach people for Christ. I also am eager to equip Christians to engage, rather than withdraw from or attack, educated non-Christians. One of the approaches I’ve developed, with the help of my RTB colleagues, is a biblical creation model that is testable, falsifiable, and predictive. I enjoy constructively integrating all 66 books of the Bible with all the science disciplines as a way to discover and apply deeper truths. 1 Peter 3:15–16 sets my ministry goal, "Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience." Hugh Ross launched his career at age seven when he went to the library to find out why stars are hot. Physics and astronomy captured his curiosity and never let go. At age seventeen he became the youngest person ever to serve as director of observations for Vancouver's Royal Astronomical Society. With the help of a provincial scholarship and a National Research Council (NRC) of Canada fellowship, he completed his undergraduate degree in physics (University of British Columbia) and graduate degrees in astronomy (University of Toronto). The NRC also sent him to the United States for postdoctoral studies. At Caltech he researched quasi-stellar objects, or "quasars," some of the most distant and ancient objects in the universe. Not all of Hugh's discoveries involved astrophysics. Prompted by curiosity, he studied the world’s religions and "holy books" and found only one book that proved scientifically and historically accurate: the Bible. Hugh started at religious "ground zero" and through scientific and historical reality-testing became convinced that the Bible is truly the Word of God! When he went on to describe for others his journey to faith in Jesus Christ, he was surprised to discover how many people believed or disbelieved without checking the evidence. Hugh's unshakable confidence that God's revelations in Scripture and nature do not, will not, and cannot contradict became his unique message. Wholeheartedly encouraged by family and friends, communicating that message as broadly and clearly as possible became his mission. Thus, in 1986, he founded science-faith think tank Reasons to Believe (RTB). He and his colleagues at RTB keep tabs on the frontiers of research to share with scientists and nonscientists alike the thrilling news of what's being discovered and how it connects with biblical theology. In this realm, he has written many books, including: The Fingerprint of God, The Creator and the Cosmos, Beyond the Cosmos, A Matter of Days, Creation as Science, Why the Universe Is the Way It Is, and More Than a Theory. Between writing books and articles, recording podcasts, and taking interviews, Hugh travels the world challenging students and faculty, churches and professional groups, to consider what they believe and why. He presents a persuasive case for Christianity without applying pressure. Because he treats people's questions and comments with respect, he is in great demand as a speaker and as a talk-radio and television guest. Having grown up amid the splendor of Canada's mountains, wildlife, and waterways, Hugh loves the outdoors. Hiking, trail running, and photography are among his favorite recreational pursuits - in addition to stargazing. Hugh lives in Southern California with his wife, Kathy, and two sons.
