[GSMNL] Radiometric dating - The theory behind Radiometric dating.

 


The theory behind radiometric dating is actually quite simple.  Every Atom of a given element has the same number of protons, but there are varieties in the number if neutrons. These varieties are called isotopes. Some of these isotopes decay (parent isotope) into other isotopes of other elements (daughter isotope). The time is takes for half of a sample of a given isotope to decay is called its half life. The half life of a given isotope can be as small a fractions of a second to billions of years. Some as far as we know are stable and do not decay.

Measurements of the half lives show that in general they are constant though there have been some reports of small variations. It is these half lives that form the theoretical bases of
radiometric dating. The basic idea is that if you have x amount of the parent isotope and y amount of the daughter isotope that given a constant half life you can calculate how much time parent isotope would have to decay to produce the measured amount of the daughter isotope.

Next the assumptions of Radiometric dating

[GSMNL] Asteroid 2014 RC

 

 
For several hours on Sunday September 7, 2014 you may not want to sat the Moon is the closed celestial object to the Earth you would be wrong. This because at 2:18 p.m. on September 7 Asteroid 2014 RC will pass 25,000 miles from Earth  or about 10% of the distancebetwen the Earth and the Moon. At just 60 feet across it is a small asteroid that will not be visible to the unaided eye. At 25,000 miles there is no danger of an impact with the Earth. In Astronomy terms this is a near miss but even if an impact occured the explosion would be at about 90 kilotons of TNT or 4 times the size of the atomic bomb dropped on Nagasaki Japan.  

Based on the Nebula Hypothesis it is claimed that asteroids a remnant from formation of the solar system but it suffers from problems such things as inbalences of angular momentum.. Also real planets both in the solar system and among exoplanets that are not in orbits predicted by the Nebula Hypothesis. Alternative theories include an exploded or shattered planet between Mars and Jupiter. They could have originated from outside the solar system which from a creationist perspective could have been created on day four of the creation week with the rest of the universe. There is  also the idea that they formed from material ejected from Earth during the Genesis Flood.
