Assignments - Soft Tissue and Carbon 14 in Dinosaur Bones
Thank-you for your comments and questions last week. I enjoyed thinking about the things you brought up. An analogy hit me as I was hiking (after a comment about how the age of rocks is measured.) Correct me if I'm wrong, but I learned that some rocks are "born" after they cool to a certain temperature that closes up the changing atoms and isotopes within them. This is when the rock starts to "decay" (or the unstable atoms start loosing matter and energy from their nuclei).
The atoms can turn into different elements or isotopes as they loose this energy and matter. Scientist measure the rate of decay, and that is how they come up with the age of the rock. We learned last week that they need to make several assumptions in this measurement, such as the assumption that the enclosed rock had 100% parent atoms (atoms that have only the original radioactive element in them) and 0 daughter atoms (atoms that have lost some of the matter and energy from the nuclei). Yet, this has never been the case in any "newborn" rocks they measure.
Anyway, it occurred to me that when we have the spirit of God in our hearts - our hearts are open to change and ready to love. It is when our hearts grow cold that they start to "decay" and we loose that energy, or life force, that helps us feel and love. So it is important that we keep our hearts warm by doing things that invite that Spirit into our hearts. Gospel principles are found all over nature. It's like God's book for us to study.
Ready for more interesting discoveries? Here are the videos and articles for the week:

Following are some findings that conclude that chemical bonds in the DNA structure have an average half life of only 521 years at 13.1C. They then summarized that it is impossible to find DNA from creatures living tens or hundreds of millions of years ago. One calculation claimed that DNA, even several million years old, would be undetectable:

In particular, pay attention to the assumptions in these videos and readings and the conclusions drawn from the assumptions.
Also watch:
2. Further study:
- Anything of interest to you in these topics (including things that refute the evidence presented here.) I was going to add a video that refutes the evidence for you to study - they all blame it on contamination - but I couldn't find any without swear words, so be cautious as you search.
