The state of physics today is like it was when we were mystified by radioactivity.They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then. Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory.But now we learn that string theory, well, is not that much of a break.The throughput rate, the rate at which the sand accumulates in the bottom chamber, is characteristic of a specific decay sequence and can be viewed as roughly analogous to the neck of the hourglass, which controls the rate at which the sand falls.(See Figure 1 below.) Secularists believe that nuclear decay has been a part of the natural world since its formation some 13.8 billion years ago, and the nuclear decay rates for the various radioisotopes have been constant throughout that time.These radiohalos originate from tiny point-like inclusions of U or some other naturally occurring radioisotope within the crystal.
Interestingly, it is in these radiohalos we find the best indirect observational evidence, measured at today’s rates of decay, supporting millions of years of radioisotope decay.This perspective, generally termed the uniformitarian view of nature, constitutes a pillar of the secularist’s worldview and is fundamental in generating the concept of deep time in the origins discussion.The Bible defines this view well in 2 Peter 3:3-4: …knowing this first: that scoffers will come in the last days, walking according to their own lusts, and saying, “Where is the promise of His coming?This feature of nuclear construction produces, groups of elements with the same number of protons but differing numbers of neutrons.
Because these families have the same number of protons in the nucleus, they also have the same number of electrons orbiting the nucleus and thus exhibit the same chemical behavior.All elements above Bismuth in the Periodic Table are unstable, i.e., they are in a constant state of releasing energy, or Each nucleus that alpha decays produces a unique set of alpha-particle energies.
