Implications for the Age of the Earth
Setterfield: Thank you for your request for information. Yes, the calculations have been done to convert radiometric and other atomic dates to actual orbital years. This is done on the basis outlined in our Report of 1987 and a the combined timeline. Basically, when light-speed is 10 times its current value, all atomic clocks ticked 10 times faster. As a consequence they registered an age of 10 atomic years when only one orbital year had passed. For all practical purposes there is no change in the rate of the orbital clocks with changing light speed. The earth still took a year to go around the sun.
Now the redshift of light from distant galaxies carries a signature in it that tells us what the value of c was at the time of emission. The redshift data then give us c values right back to the earliest days of the cosmos. Knowing the distances of these astronomical objects to a good approximation, then allows us to determine the behaviour of light speed with time. It is then a simple matter to correct the atomic clock to read actual orbital time. Light speed was exceedingly fast in the early days of the cosmos, but dropped dramatically. At a distance of 20 billion light years, for example, the value of c was about 87 million times its current value. At that point in time the atomic clocks were ticking off 87 million years in just one ordinary year. When the process is integrated over the redshift/cDK curve the following approximate figures apply.
NOTE: When the redshift/lightspeed curve is matched to history, it turns out to have an almost exact fit. We can look at the past ages and see where they fit into the biblical timeline by way of the use of the lightspeed curve.
The curve showing the lightspeed through time is here.
The results, shown in terms of biblical patriarchal ages, is here. (BP means "before present")

Setterfield: This formula only applies on a small part of the curve as it drops towards its minimum. Note that "D" is atomic time. Furthermore, 't' or orbital time, must be added to 2800 bc to give the actual BC date. The reason for this is that 2800 BC is approximately the time of the light-speed minimum.
The more general formula, but still very approximate, is D = [1905 t2] + 63 million". In this formula "D" is atomic time, and once the value for "t" has been found it is added to 3005 BC to give the actual BC date. This is done because the main part of the curve starts about 3005 BC when the atomic clock is already registering 63 million years. Working in the reverse, therefore, if we take a date of 5790 BC we must first subtract 3005. This gives a value for "t" of 2785 orbital years. When 2785 is squared this gives 7.756 million. This is then multiplied by 1905 to obtain 14.775 billion. From this figure is then subtracted 63 million to give a final figure of 14.71 billion. This is the age in years that would have been registered on the atomic clock of an object formed in 5790 BC.
