Pulsating Moon Contradicts Plate Tectonics



"The net result of the electrical imbalance will be the pulsation of the Earth (expansion-contraction), which is superimposed on its expansion." -- Stavros T. Tassos, seismologist, 1998

Science Daily: NASA's Lunar Reconnaissance Orbiter Reveals 'Incredible Shrinking Moon'.

ScienceDaily (Aug. 20, 2010) — Newly discovered cliffs in the lunar crust indicate the moon shrank globally in the geologically recent past and might still be shrinking today, according to a team analyzing new images from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. The results provide important clues to the moon's recent geologic and tectonic evolution.

Earth and Moon Formed Later Than Thought



"Capture of our Moon becomes the only option, it cannot have been created from the Earth." -- Wallace Thornhill, physicist, October 2000

Science Daily: Earth and Moon Formed Later Than Previously Thought, New Research Suggests.

"Our results show that metal core and rock are unable to emulsify in these collisions between planets that are greater than 10 kilometres in diameter and therefore that most of the Earth's iron core (80-99 %) did not remove tungsten from the rocky material in the mantle during formation," explains Dahl.

The result of the research means that Earth and the Moon must have been formed much later than previously thought -- that is to say not 30 million years after the formation of the solar system 4,567 million years ago but perhaps up to 150 million years after the formation of the solar system.

Moon Mantle Is Rigid



The lunar surface has been mapped and it's crust and mantle are solid and rigid with no liquid beneath the surface.

To me this is another piece of evidence that suggests there is no water inside Europa and therefore the moons are growing: Most Detailed Lunar Map Suggests Little Water Inside Moon.

In part, the new map will serve as a guide for future lunar rovers, which will scour the surface for geological resources.

But Araki and his colleagues did something more with the map: they measured the roughness of the lunar surface, and used that information to calculate the stiffness of the crust.

If water flowed beneath the lunar surface, the crust would be somewhat flexible, but it wasn't. The surface was too rigid to allow for any liquid water, even deep within the Moon.

Earth's surface is more flexible, by contrast, with the surface rising or falling as water flows above or below ground. Even our planet's [alleged] plate tectonics is due in part to water lubricating the crust.

And Mars? On a scale of surface roughness, it falls somewhere between the Earth and the Moon, which indicates that there may have once been liquid water, but that the surface is now very dry.

No surprise there.

But Mars' roughness coupled with the complete absence of plate tectonics suggests that if there is water in the red planet's interior, it is not located near the surface, where it could lubricate the crust, Shum explained.

The LALT map is the most detailed lunar map ever created.
