I have recently been studying creation and found it to be a fascinating subject. I am no scientist so everything you read in this is really things I have learned from other scientists. In particular I have really enjoyed Dr. Gentry’s work who so happens to be an Adventist. I really recommend checking out his website at www.halos.com for further information. In this article I will be discussing Dr. Gentry’s work on radioactive halos in granite rock that he has worked on for over 40 years. To the best of my knowledge it appears his work still stands today as solid evidence of a young earth that was created in six literal days.
We start with Hebrews 1:10 where it says “You, LORD, in the beginning laid the foundation of the earth, And the heavens are the work of Your hands”. What might the foundation of the earth be made from? It’s interesting that Jesus is our foundation. “For no other foundation can anyone lay than that which is laid, which is Jesus Christ.”(1 Cor 3:11) We are also told to look to Jesus the author and finisher of our faith(Heb 12:2). Christ so happens to be our Rock: “all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ.”(1 Cor 10:4) By studying(knowing) the Son of God our Rock we are studying a sure foundation that the gates of Hades cannot prevail against. “He said to them, “But who do you say that I am?” Simon Peter answered and said, “You are the Christ, the Son of the living God.” Jesus answered and said to him, “Blessed are you, Simon Bar-Jonah, for flesh and blood has not revealed this to you, but My Father who is in heaven. And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it.”(Matt 16:15-18) What does all this have to do with creation? You may notice that I am making a spiritual connection with Christ as our foundational Rock through whom the foundation of the earth was laid. Might the foundation of the earth be made of “rock” and have evidence that gives us an immovable platform on which to stand firm that God created the heaven and the earth in six literal days?
Evolution says hot magma slowly cooled over millions and millions of years under high pressure to produce the earth’s granite rock. In this magma one can find the radioactive isotope of Uranium 238. After the magma has cooled and solidified into granite this Uranium is trapped in the granite rock. Uranium 238 is unstable and decays over time which is called half-life. While trapped in the granite rock the Uranium is decaying into daughter isotopes. Here is the process of which Uranium 238 breaks down found in Dr. Gentry’s book “Creations Tiny Mystery”:
Uranium-238 initiates a chain of steps which ends in the element lead (chemical symbol Pb). The 238U decay chain, as shown below, has some daughters which decay by emitting a beta (?) particle, which is nearly 7400 times lighter than the more massive alpha (?) particle. The type of decay is shown by the symbols ? and ?.
The half-life of a radioactive isotope is the time required for half the atoms in any collection to decay. If 1000 atoms exist at a certain time, then only 500 will remain after one half-life, after two half-lives only 250 atoms of the original collection will remain, and so forth. Half-life and decay rate are closely related quantities. isotopes that decay quickly have short half-lives; those that decay more slowly have longer half- lives. At present 238U is decaying very slowly with a half-life of 4.5 billion years.
While this Uranium is decaying in the granite rock it leaves behind a signature called “halos” in the granite rock. Only alpha decay leaves its signature so counting in the model above we see that Uranium has 8 steps of breaking down via alpha decay until it reaches the stable daughter of lead 206. When analyzing a piece of granite under a microscope that has a piece of Uranium 238 in it one will find these “halos” that have 8 rings. Scientists can study these halos left behind to find out the composition of the substance trapped in the granite even though it may have broken down completely into Lead 206. Here is a chart from Dr. Gentry’s book “Creations Tiny Mystery”:

With a half-life of 4.5 billion years it is very reasonable that Uranium would become trapped in the granite as the magma cools over millions of years. During its decay it would leave these spherical halos behind in the granite as evidence. Thus far you can see that this is hardly evidence for creation but hold on. What would you say if Uranium had only a 3 minute half-life? It doesn’t but I’m laying down an example. The Uranium would have decayed into daughter isotopes long before the magma cooled into granite. If the daughter isotopes had long half lives of millions of years you would find their signature left behind but you wouldn’t find the parent signature from the Uranium as it would have decayed while in molten lava which can have no halos.
It’s interesting that Dr. Gentry has found earth's granite rock is full of Po 218 (polonium) halos without the Uranium 238 parent. These halos start with Po 218 as the parent and then break down into Po 214 and Po 210 until reaching Pb 206 (Lead). Look back to the breakdown chart above keeping in mind that beta decay doesn’t leave a signature. These are three ringed halos found in abundance in granite rock throughout the world without any of the isotopes between U 238 and Po 218 (refer to breakdown chart). What is the significance of finding Po 218 halos in granite rock? Po 218 has a half-life of 3 minutes so as a parent cannot exist on its own in nature. It breaks down very fast so 100 atoms would break down to 50 in 3 minutes, 25 in 6 minutes, 12 in 9 minutes, 6 in 12 minutes, 3 in 15 minutes and ultimately in less than a half hour would be gone. It is impossible to have Po 218 halos in granite rock as the granite took millions of years to cool down supposedly. Yet they are there and evolutionary scientists know this calling it a “Tiny Mystery” that will someday be solved. Of course they attempt to theorize how this has happened but as with any error it’s always based on assumption. How can Po 218 be leaving its signature in granite rock? “By the word of the LORD the heavens were made, And all the host of them by the breath of His mouth. He gathers the waters of the sea together as a heap; He lays up the deep in storehouses. Let all the earth fear the LORD; Let all the inhabitants of the world stand in awe of Him. For He spoke, and it was done; He commanded, and it stood fast.”(Psalm 33:6-9) “Of old You laid the foundation of the earth, And the heavens are the work of Your hands.”(Psalm 102:25)
Simply put; Po 218 must have been created inside the granite rock when the Lord laid the foundations of the earth nearly instantly. You could not have Po 218 halos if granite cooled from magma over millions of years because the half-life is to short. Another key piece of evidence is scientists even 40 years after Dr. Gentry made this discovery have not been able to synthesize granite in the lab as it appears in nature. Attempts always turn out to be like rhyolite which has tiny crystals instead of the large crystals found in granite. Thus far only God has been able to create the large crystalline granite found in and on earth with Po 218 halos enclosed. Dr. Gentry made these discoveries back in the 60’s and 70’s and the rock still stands firm to its true origin today. Scientists should pay closer attention to the rock and so should Adventism pay closer attention to the Rock as the “Son of the living God” as He is our foundation that no man can take away. Amen.
