Wouldn't it be wonderful to find the cave was used by ancient extraterrestrial visitors to Earth to store footage of the planet's early history, specifically life's beginnings up to and including the dinosaur years? But it's probably just a big hole. Wink

im no archioplanetary scientist ...
it would seem kinda logical to imagine potential cave systems in the moon left by contracting lava as it cooled.
you know any mathamaticians ?
probably should be a formula to calculate the statistical probability frequency & rough cave density based on computer modeling or the type of formation & cooling & gravitational effects.

imagine if they found highly advanced life fossilised in the cave dating back a million years.

exciting !

EXCERPT: Scientists from the Japan Aerospace Exploration Agency who discovered the cave say that it could be used as a base for astronauts, especially if it's found to contain water....

Quote:Stephen Hughes, a professor in the Department of Chemistry, Physics and Mechanical Engineering at the Queensland University of Technology says that it's possible that there is an extensive array of lava tubes all over the moon.

and we all know what is left behind by lava... massive precious gems and gold & rare minerals/metals...
potentially it would be quite the resource that propells the species into interstella travel, or lights the fire of greed that burns the civilisation to the ground.

The more you find the less rarer they get.  Smile

exosplunking?

@RainbowUnicorn

There was a certain amount of data available in regards to lava cavities that I came across while trying to deal with Norval (Craterchains).  While his subject matter wasn't particular convincing (BET - Bad Extra Terrestrials leaving large bulletin messages [words etc] on planets through detonating nuclear weapons or some such), some of the material I found while debunking him was relevant e.g. Lava Tubes (wikipedia.org)

While indeed there has been many suggestions of man returning to the moon for many different reasons, this particular one would be of scientific investigation and therefore likely aid in meriting why it should happen sooner rather than later.

my err, i was actually being serious. referring to the known geological process and mineral deposits etc.
giant precious gems as an example based on the potential of long time periods un-touched etc etc..

i was thinking in a very simple manner e.g Gold Deposits on lava tubes for a modest ... lets say 5000 kilometers.
would be an awful lot of gold.
more soo potential of rare new mineral deposits created in low gravity or by coalescent process etc.
only 10 tons of some new ultra light weight incredibly strong alloy would leap frog modern technology by decades/generations potentially...or even less.
maybe only a few kilos might be enough to map & figure out how something is made to allow science to reproduce something.

a flexible crystal layering that can be sprayed on in a directional manner to allow strength 50 times stronger than steel yet flexible like fabric in 1 direction (musing).

From what I read, it's hypothesized that this large cave that the Japanese discovered might be a lava tube. There is evidence of extensive lava flows on the Moon, so lava tube caves may (or may not) be expected too. Would cave formation be the same as it is on Earth in lunar temperature, atmospheric and gravity conditions? We are talking about extensive lava flows that produced the Moon's "seas", not just streams of lava emerging from Earth volcanos that produce tubes here on Earth. Much of the surface of the near side of the Moon seems to have been fluid at some time (or various times). I can imagine (science-fiction imagination is all it is) huge voids underneath the lunar "seas", created when the surface cooled and solidified over a hotter still-liquid layer that continued to flow. That wouldn't produce mere tubes, but extensive galleries miles wide.

If water ice has been found in shadows that never are illuminated by sunlight near the lunar poles, it might be even more likely in lava tubes that are always dark.

But... sadly my belief is that lava tubes are usually kind of featureless inside. Just rock tubes. That's how they appear here in California, at Lava Beds National Monument. See here. They don't display the stalactites, stalagmites and the large crystals that one sometimes finds in limestone caves created by liquid water dissolving cavities in the rock, creating crystals by evaporation.
