According to a new research co-authored by Stephen Meyers, Ph.D., at the University of Wisconsin-Madison, and Alberto Malinverno, Ph.D., a research professor at Columbia University's Lamont-Doherty Earth Observatory, the moon is now moving away from the Earth at a rate of 3.82 centimeters per year adding 2 milliseconds to Earth days every century.
"One of our ambitions was to use astrochronology to tell time in the most distant past, develop very ancient geological time scales".
Meyers and his team wanted to know how the moon's orbit affects Earth's rotation. By looking at the Earth's Milankovitch cycles, they were able to see how the Earth has tilted and wobbled, as well as how the climate has shifted to give us our lengthened days. Scientists like Meyers have observed this climate rhythm in the rock record, spanning hundreds of millions of years.
Another complication is the chaotic Solar System theory - the idea that, rather than having regular and highly predictable orbits, over time the objects in the Solar System are growing more chaotic. Still, the further back in the rock record he and others have tried to go, the less reliable their conclusions.

VoteVets is also still blocked by Trump, the progressive veterans organization tweeted Monday. Clearly, the White House disagrees.
The moon is moving away from our planet at just 3.82cm a year, which is having a small, but measurable effect on Earth's movement.
However, scientists have established that the moon is 4.5bn years old. One layer was taken from a 55 million-year-old rock from the Walvis Ridge in the Atlantic Ocean, and the other taken from a 1.4 billion-year-old rock from Northern China.
As the rotation of Earth is going on slow and slow, the distance between Earth and lunar surface is increasing. Earth days, apparently, will just keep getting longer from here on out. "But when we start to think about destinations that are further than the moon, like Mars, or staying on the moon for a long time, we need to start thinking about the infrastructure we want to have in space that can be used multiple times".
Meyers provided his theory at the Lamont-Doherty Earth Observatory in 2016 where Alberto Malinverno, a teacher at the Columbia University revealed his interest in the research study. This was at least in part because the moon was closer and changed the way Earth spun around its axis. Changes in the climate due to orbital changes are called orbital forcing. This was before the period of spreading of the complex life across the globe.
Normally, Crampton said, changes in Earth's orbit would be calculated by astronomers, rather than palaeontologists. They referenced 2 of the earlier research study made on Milankovitch cycles and rock records.
