In the last 100 years, God has provided mankind with the ability to look way out and way in. In both directions, they find WONDER!
11 The heavens are yours, and yours also the earth;
you founded the world and all that is in it. Psalm 89:11
We are on number six of the “10 Best Evidences From Science That Confirm a Young Earth” by Answers In Genesis. I watched a video several years ago that talked about this one.
#6 Helium in Radioactive Rocks
“During the radioactive decay of uranium and thorium contained in rocks, lots of helium is produced. Because helium is the second-lightest element and a noble gas, meaning it does not combine with other atoms, it readily diffuses (leaks) out and eventually escapes into the atmosphere. Helium diffuses so rapidly that all the helium should have leaked out in less than 100,000 years. So, why are these rocks still full of helium atoms?
While drilling deep Precambrian (pre-flood) granitic rocks in New Mexico, geologists extracted samples of zircon (zirconium silicate) crystals from different depths. The crystals contained not only uranium but also large amounts of helium. The hotter the rocks, the faster the helium should escape, so researchers were surprised to find that the deepest, and therefore the hottest, zircons (at 387oF) contained far more helium than expected. Up to 58% of the helium that the uranium could have ever generated was still present in the crystals.
The helium leakage rate has been determined in several experiments. All measurements are in agreement. Helium diffuses so rapidly that all the helium in these zircon crystals should have leaked out in less than 100,000 years. The fact that so much helium is still there means they cannot be 1.5 billion years old as uranium-lead dating suggests. Indeed, using the measured rate of helium diffusion, these pre-flood rocks have an average “diffusion age” of only ~6,000 (4,000-to-8,000) years.
These experimentally determined and repeatable results, based on the well-understood physical process of diffusion, thus emphatically demonstrate that these zircons are only a few thousand years old. The supposed 1.5 billion-year age is based on the unverifiable assumptions of radioisotope dating that are radically wrong. Thus, all available evidence confirms that the true age of these zircons and their host granitic rock is only 6,000 (+/- 2,000) years.”
This one is definitely a case of “follow the science.” Rather than manipulate the findings to say what they want them to say, they simply reported what they found. Tomorrow, we look at Carbon-14 in fossils, coal, and diamonds.
Abba, the evidence is stacking up! Keep showing Your Word to be true, Amen.
