The Slowing of Earth Rotation and Lunar Recession


For over 40 years scientists have been able to measure the distance between the Earth and the moon with incredible accuracy using retro-reflectors left on the moon by Apollo astronauts. These measurements  have shown that the moon is receding from the Earth at 3.82 cm (1.5 inches) per year. Measurements of the Earth rotation rate by way of atomic clocks has also shown that an Earth day is getting longer at a rate of 1.7 milliseconds per day per century.  

These two phenomenons are inter-related through the tidal forces between the Earth and the Moon. It has been know for decades that when these figures are plugged into the laws of physics that they show that the Earth moon system can not be more than about1.25 billion years old.

Calculations such as these are largely dismissed by proponents of a 4.5 billion years old Earth. They also point to paleontological data as evidence that the moon is receding and it is receding at a rate compatible with 4.5 billion years. These claims not only ignore alternative interpretations of the fossils and rocks in question but they usually use only one or two data points when multiple data point are used the scattering in the data is not what would be expected if it were really a result of the slowing of the Earth rotation.


However plugging any model using a 4.5 billion year old earth-moon system into the laws of physic never produces the current Earth-Moon system with out significant tweaking and then the always come in below the paleontological data. This includes the currently accepted “Giant Collision Hypothesis of the Origin of the Moon.”


Furthermore plugging the same paleontological data is  into the same laws of physics produces a maximum age for the Earth-moon system of about 2.067 billion years. Tweaking this model to make it reach 4.5 billion years requires putting an impossibly small delay time in high tide of less than 24 seconds.

There is simply no way of reconciling a 4.5 billion year old Earth-moon system with the laws of physics and the paleontological data claimed as evidence for the same. They simply do not and can not be made to match up. All of this makes a very strong case that earth-moon system can not be 4.5 billion years old.

While this dose not prove that the Earth is 6-8 thousand years old it is consistent with what we would expect if it were 6-8 thousand years old and  paleontological data was simply an interpretation of rocks and fossils assuming an older Earth. The dispersion in the data is not what would be expected if the the Earth had truly been slowing for billions of years.



Lunar recession and the Age of the Earth

This video is a detail and math intensive look at lunar recession and the age of the Earth.
If you do not think you can handle the math then watch the shorter version below that eliminates the math.

Lunar recession and the Age of the Earth Short Version

This video is a shorter version of the one above the excludes the math. It is still a detail look at lunar recession and the age of the Earth.
If you dthink you can handle the math then watch the longer version above



This program provides illustrates the principle of reducing entropy and there by producing order from disorder

Convention 1: W is used instead of W since Greek letters could not be used.

Convention 2: The value of We and Ws are not adjusted for the number of particles to avoid extremely large numbers.

 These conventions do not change how well it illustrates the participle of order from disorder..
