Countless mysteries abound about our moon, some more esoteric than others.

Is the moon a hollow space station created eons ago by extraterrestrials? Is it actually a chunk of the Earth blown off by a collision with Planet X, or Nibiru, as recorded by the ancient Sumerians? (This is in fact very similar to the predominant theory held by science about how our moon was created – see below.) Or is the moon an artificial satellite carefully put into place by our creators (or ancestors?) in order to allow for the important life-sustaining Earth phenomena that are linked to the precise placement of our moon (tides, etc.)?

In any case, new analysis of moon rock suggests that we know even less about Earth’s mysterious moon than we thought – but exactly how much less?…

Goodnight, Old Moon

by Sid Perkins

A new analysis of a lunar rock brought back by the 1972 Apollo 16 mission suggests that the moon could be tens of millions of years younger than previously thought. Another possibility, scientists say, is that current models of how the moon cooled in its early years may be totally wrong.

The predominant theory of the moon’s origin holds that a Mars-sized object slammed into Earth soon after the solar system formed about 4.56 billion years ago. After the impact, large volumes of melted material splashed into space, coalesced, and cooled into today’s moon. Previous studies of lunar rocks suggest that the sea of molten rock covering the lunar surface began to solidify anywhere between 4.43 billion and 4.53 billion years ago. But those dates aren’t very precise, largely because the concentrations of the trace elements used in the dating techniques are extremely low, says Lars Borg, a planetary scientist at Lawrence Livermore National Laboratory California. Now Borg and his colleagues have used several methods of radioactive dating to come up with a new—and surprising—date for when the moon’s magma ocean cooled…

Imagine that you are from a society living thousands of years in the future. You are on a spirit walk through the high desert, and you stumble upon a mysterious monument tucked inside a lone mountain. Upon closer inspection you find that the monument is in fact a clock – a clock that has been telling time for almost 10,000 years…

In the video below, Alexander Rose discusses the design and construction of the 10,000 Year Clock. What are the challenges and responsibilities incumbent upon the current generation when thinking for the long-term future?

The implications of this discovery are staggering. Not only does this imply that the seeds of life are floating all over the not-so-sterile universe, but it’s likely that space is a cesspool of biology… how wonderful!

DNA Meteorites: Life Falling From The Sky

Posted by Robert L. Gidley

DNA meteorites have been confirmed as real by a recent report in the August 9 edition of Proceedings of the National Academy of Sciences. Components of DNA, including nucleobases, have been found in 12 meteorites analyzed using the latest scientific methods.

This was the first study that successfully showed that the nucleobases did not come from contamination. To rule out contamination, the study analyzed the areas where the meteorites came from to rule out possible earthly contamination.

Three of the nucleobases found were also very rare in terrestrial biology,

“Finding nucleobase compounds not typically found in Earth’s biochemistry strongly supports an extraterrestrial origin,” study co-author Jim Cleaves, a chemist at the Carnegie Institution of Washington, told SPACE.com…
