    Science.

    This is for any generally interesting things in the science world.

    Mauna Loa is restless. For the first time in years, the HVO has had to raise the Alert level from Normal to Advisory.
    Color code Yellow.
    Mauna Loa has been experiencing elevated seismic activity and summit inflation. The area near the summit has expanded over 6cm in recent months.
    Like a giant zit, it's getting ready to pop.

    I found the waveforms for Mauna Loa. I don't know why but the USGS practically hides those for the Hawaiian Islands.
    The seismic stations around Mauna Loa are reading constant earthquake activity called Harmonic Tremor.
    Lot's of Magma is definitely filling the volcano.

    Well... Volcanology and Seismology both involve some of the largest cracks around.
    It involves studying cracks in Terra.
    The cracks are very interesting. They come in all shapes and sizes and all different positions.
    Is it normal, reversed, strike slip or even bilateral.
    If you stumble across the wrong crack, you can fall right in.
    My favorite activity is going out into nature and drilling into a crack, just to see what's there.
    Cracks all have there own personality, kinda like finger prints.

    Mauna Loa Update.

    This was not volcanic tremor although it looks similar. It turns out it's some kind of man made issue in or near a quarry on the South Western slope of Mauna Loa.
    I hope nobody lives to close to that quarry...

    The heartbeat of Mauna Loa as magma oozes through it and rock snaps under the pressure.
    When will it pop?

    The lower (narrow) lines on the graph are normal background, the wider sections between the arrows are it's soul stirring.

    Ancient ice ages linked to volcanic activity and climate change

    pretty clear they're linked, but which comes first? seams the more we learn the stronger the evidence that volcanic activity picks up going into and out of glacial periods

    Hawaii also had a "slow earthquake" a couple of days ago. The whole south end of the island slid 1.5" towards the coast. That is the most scary thing of all. The piece of land between the South West and South East Rift Zones will slide into the ocean one day.
    Owning land on the South Coast of Hawaii is a bad idea.
    The geologists figured out those huge landslides are why the Hawaiian Islands have those spectacular coastal cliffs in some areas.

    Science.

    Did you guys read the article about how Seattle is more dangerous from natural catastrophes than the Bay Area? That's kinda scary. They have a ton of old bridges and tall brick buildings.

    Seattle Is One of the Most Dangerous Places in the World - Slog - The Stranger
    Yes. I study geology on the side for fun.
    The North West has several disasters in the making.

    1. The Juan De Fuca Plate going under the North American Plate at the Cascadia Subduction Zone will cause a earthquake and Tsunami to rival the one that hit Japan a few years ago. There will be far less warning, since the trench is right on the coast.

    2. Volcanoes like Mount Saint Helens are small firecrackers compared to whats in store for the Pacific Northwest in the future.
    Not only that but other major Cascade volcanoes are far closer to major cities.
    A simple Lahar could wipe out one of the major cities in minutes, burying them under tens of feet of mud.

    3. Earthquakes. The Pacific Northwest has some of the most dangerous faults in the U.S. although Alaska is still the worst state in that respect. Alaska also has plenty of dangerous volcanoes.

    4. Debris flows. You don't need a volcanic eruption to wipe out a town or city with volcanic debris. Melting glaciers or heavy rains can cause a huge landslide to come down from one of the large volcanoes and bury a town or city.

    Most people there worry about the rain.

    Cool stuff guys.
    I was watching Secrets of the Dead a couple of nights ago, and some little Costa Rican Lawyer turned amateur archaeologist has made fools of big name Egyptologists, while looking for Cleopatra's tomb in a temple that was supposedly "unfinished".

    Science. 454 pages of doctoral research saying that:

    full suspension is better on rough ground
    hardtails are percieved as more efficient when climbing on rough ground

    That behavior has been noticed in elephants for a quite a long time too. There have been instances where the elephants have come back a year or so later and mourn the loss. Animals really are amazing creatures that are capable of many things, more than we give them credit for.

    Lightning

    here is a super slow motion video of a lightning strike. (there are others)

    https://www.washingtonpost.com/news/...me-rate-video/

    I also am fascinated by sprites. it's like super lightning really, really high up in the atmosphere and it's not very well understood. they were only discovered 25 ish years ago and they are hard to catch in action.

    the results of a lightning strike on a golf course.

    Heard about those a year ago when a research paper was able to gather enough real, repeatable data to prove they exist. Lots of pictures from the international space station were needed because they are so rare. Interesting, and they basically say FU to the standard lightning physics.

    We saw a couple of similar patterns in the ground near our campsite after sitting through a wicked lightning storm in the Sierras many summers ago. We were above 10,000' and had just unpacked and set up camp when that storm barreled in.

    I wasn't afraid of much in my early 20s, but that experience was terrifying.

    One evening, with his charge at full capacity, Micro Farad decided to get a cute coil to discharge him. He went to the Magnet Bar to pick up a chip called Millie Amp. He caught her out back trying self induction; fortunately, she had not damaged her solenoid. The two took off on his megacycle and rode across the Wheatstone Bridge into a magnetic field, next to a flowing current , to watch the sine waves.
    Micro Farad was very much stimulated by Millie's characteristic curve. Being attractive himself, he soon had her field fully excited. He set her on the ground potential, raised his frequency, lowered her resistance, and pulled out his high voltage probe. When he inserted it in parallel, he short-circuited her shunt. Fully excited, Millie cried out, "ohm, ohm, give me mho". As he increased his tube to maximum output, her coil vibrated from the current flow. It did not take long for her shunt to reach maximum heat. Now with the excessive current shortening her shunt, Micro's capacity rapidly discharged – every electron was drained off. But that was not the end of it. Indeed, they fluxed all night, tried various connections and hookings until his bar magnet weakened, and he could no longer generate enough voltage to sustain his collapsing field. With his battery fully discharged, Micro was unable to excite his tickler, so they went home. A few weeks later, they were merged forever and oscillated happily ever after.

    There is a list of ~10 possibilities why we haven't found other civilized life yet, assuming the Galaxy should be colonized already. There is one 11th reason they left off: the possibility that we ARE an alien colony, seeded interstellarly through some early deposit of simple organisms or life precursors.

    I'm not sure i understand, is there something bad there? should i take the link down? I didn't have any problem or i wouldn't have posted it, but i use a lot of blockers.

    colonizing a galaxy? that's a pretty big task. think about it, we can barely get to the moon, how do you expect a species to travel 100,000 light years like it's all a big city?

    no question, we are the aliens. people just don't usually think about it that way though. I don't think we were seeded, there's a pretty well established line of the evolution of life that started in the oceans. mostly in the shallows where there were huge tides early on because the moon was 4-5 times closer to earth then.

    Yeah, so the fundamental assumption of the Fermi paradox (and a view held by Sagan and many others, rightly or wrongly) was that given enough time without being hit by a gamma burst or wiping itself out, an advanced civilization would eventually become type 2, harnessing the energy of entire stars, and solving interstellar travel. Even at a slow 95% of the speed of light, a galaxy 100,000 light years across could be colonized in under a billion years.

    As to the beginning of life, there are still some very big questions which are unsolved, such as how did naturally occurring amino acids (which we have found in comets and have created from scratch in lab conditions) transition to self replicating cells like RNA/DNA or some precursor. We may prove those happened on earth or elsewhere. Whatever the answer, it must have happened somewhere so the point is kind of moot.

    I think it's interesting stuff for sure, but not the work of little green men IMO.

    what i do still have questions about are unexplained sightings by astronauts. a few have said in interviews that they can't explain what they saw. there's even video of unexplained things/crafts in space taken from ISS. nobody seems to talk about it much. i guess i'm only skeptical because if they (the aliens) were here, why not just come out with it? what's the big deal?

    i love that we can give classifications to things that don't exist, that we know of.

    the notion that anyone could harness the energy of a star or travel at 95% of the speed of light is pretty far fetched IMO and only exists in sci-fi stories. these ideas get thrown around very lightly without a good understanding of the unimaginable difficulty involved.

    I do wish i could check back in with humanity/earth in 1000 years, 100,000 years, 10 million years, etc. to see what's going on. how does this story end? ( also in another 15-100 billion years to see what happens to the universe?)

    right. I'm also curious if there is life on Europa (ice moon of Jupiter). i read a couple years ago that they were thinking of sending a probe there that could melt it's way through the ice and explore the oceans below. that would be pretty awesome.

    LOL. You better send a note to Hawking on that and tell him he has no idea what's involved. Sagan too, next time you see him.

    The technology we've developed in the the last several years would be unimaginable to even DaVinci. Every time we've reached what we believe to be an absolute limitation, we've overcome it in a cosmic microsecond. We can't foresee what will come and what discoveries we'll encounter (in the next million years, unless Gamma ray burst or self annihilation). Quantum mechanics has many secrets yet to reveal. The LHC team is about to announce a newly discovered particle. Quantum entanglement is real and re-creatable.

    I'm on it.

    one of the biggest hang-ups IMO is our capacity to store energy. it's pathetic. we don't have a technology that can support deep space travel. batteries go bad in a couple years, liquid oxygen runs out, what else is there? there haven't been any major advancements in that department in 50 years. without solar, and constant refueling, we're helpless in space.

    look how much fuel is burned during a rocket launch, it's like 80% (?) the total weight of the entire vehicle.

    They created us, and now they're gone, for whatever reason. Maybe UFOs are just monitoring us like ants in an ant farm?

    Yeah agree it's completely impossible with rocket propulsion.

    Hawking has suggested a dyson sphere to focus the energy of a star on a solar sail. Sagan was big on on the nuclear ram jet concept. But it will probably be none of those - There are things we can't foresee now.

    Silly TV show, yes. The archeological evidence of things we'll probably never figure out how were constructed, and for what reasons, are much more convincing than fake footprints and grainy photos of a dude in an ape suit.

    we may never figure certain things out, i agree, but we're also probably trying to read too deeply into what was possibly one guy's idea. someone of power just got it into their head to build something and did it. stonehenge, Nazca, etc.

    frankly that stuff doesn't interest me much. ancient cultures are interesting, but I'm more into geology, the history of the earth/solar system, astronomy and physics. the quantum world kinda blows my mind, pyramids are just big triangles to me.

    I'm interested in that stuff, too, it all ties in with everything else. I'm blown away by what's been left behind by the ancients, IMO they understood quantum world, which is why they were able to do and build the things they did. What was created goes way beyond what hundreds or thousands of man-hours could have produced over hundreds or thousands of years. And this was happening all over the planet! It wasn't one guy with a lot of power going: Hey, let's build a pyramid!

    I could watch Ancient Aliens with the volume off and still be blown away. The evidence of technologies beyond are comprehension is apparent. This ain't no hammer and chisel work:

    Cornfield, this is the science thread, not the pseudo-science thread. Humans have been able to carve smooth rock for thousands of years. The Lake Titiacaca ruins are impressive but similar feats have been achieved all over the world. When a civilization has plentiful food and water, and a surplus of labor, much is possible . . . as we have seen in Inca, Aztec, Easter Island Ruins, Stonehenge, the city of Petra, the list goes on. All these have been shown to be possible with primitive tools and sufficient time and resources.

    Corn, i think it's remarkable what ancient people were able to accomplish, really. it's impressive even by todays standards, and the techniques often cannot be duplicated today as the skills haven't been passed down.

    but ancient astronauts theory lacks scientific data. this is the third paragraph from the wiki page you linked.
    The idea that ancient astronauts actually existed is not taken seriously by academics, and has received little or no credible attention in peer reviewed studies.[5] Ancient astronauts have been widely used as a plot device in science fiction.
    it's cool that you into it, there's a lot to be learned there, but taking unexplained phenomena as proof of aliens is a bit of a stretch.

    Some maybe, but not all. As a novice woodworker/carpenter I have a hard enough time working with little sticks and boards. What was done in the past involved stones weighing many tons which were fit together as if they grew there. Sure, there could have been techniques to do this that have been lost, but it's really hard to imagine ropes and pulleys lifting and setting these things in place, even with hundreds of workers, or animals providing leverage. Almost seems like there would have to be some kind of knowledge of anti-gravity, and how to use it. Where that knowledge came from is also a mystery, and we may never know the answer.

    Lacking data for those that need absolute proof, sure, and that data may never come to light. I'm just going by what I see as being impossible for humans to create without knowledge that goes way beyond what we today understand. I cannot say for certain that the ancient aliens existed and had a hand in creating these things, but it's fun to think they did, and it would explain a lot of things if they did.

    My friends think I'm crazy for being into this stuff, you guys ain't the only ones.

    not sure, but it's a really small number. in all likelihood there are many other "intelligent" species out there, and even more planets with some form of life, but as the article states they're just so far apart it will be 100's of millions of years before we are likely to hear from them.

    given the vast distances involved i think it's unlikely an intelligent alien species would waste time searching randomly through mostly empty space (unless they harnessed the ability to predictably use worm holes). even if they did it would probably be just a small probe type ship, not one that would try to take over the world. I mean common, lets be realistic about our hypothetical alien encounters.

    "Fully rigid" isn't a thing.

Almost seems like there would have to be some kind of knowledge of anti-gravity, and how to use it. Where that knowledge came from is also a mystery, and we may never know the answer.
    Its fun to believe it might be aliens but that's one of the least probable scenarios - every time something can't be explained, to say it must be aliens, is a modern form of theism.

    Watch a few of these:

    This shows how Easter Islanders might have moved their giant statues:
    https://www.youtube.com/watch?v=YpNuh-J5IgE
    The idea for it came from the fact that the Rapa Nui mythology says that the statues 'walked' to their locations. There is an extended NatGeo special on Easter island covering this in more detail.

    This shows how bronze age Navateans probably built the City of Petra, skip to 31m, 2 guys show that it can be done with bronze age tools by the end of the show.

    There was a nova or history channel or nat geo special on Lake Tatiacaca where they demonstrated how the smooth rock could be achieved with primitive tools, I can't find it now, I will look for it. Humans have routinely found ingenious ways to move large amounts of stone and built large, complex structures which seem only possible with modern tools. Lake Tatiaca structures were built by stone age societies, not bronze age, but the Petra example shows how human creativity, combined with the right enthusiasm (usually religious) and surplus of resources can achieve some pretty amazing feats.

    If aliens do exist...
    If they do and have the technology to travel from one star to another I truly doubt we would know they are here. The brain capacity difference between a human and a deer is huge. With that a human can go into the forest wearing camouflage and scents and remain undetectable by the deer. The human can take pictures and study the deer without it ever knowing we are there. The brain power difference between an alien who can travel to earth from a far away star and us is more like human to ant. So all of this crap about abduction and UFO's..we are the deer. They could do all of this without us ever knowing they came. I have no doubt there is other life and civilizations out there but again, we would never know.
    The other thing is if an alien civilization has the technology to get here we sure as hell better hope they are friendly, or again, we are the deer.

    Here is a debunk about the Puma Punku ruins close to Lake Titicaca, the H structures above.

    https://youtu.be/Fn4AoAZMRqM

    The references for this video can be found at the bottom here:
    Puma Punku | Ancient Aliens Debunked

    The wikipedia article on Puma Punku confirms some of the facts from this debunk video, such as the fact that the stone is Sandstone (not granite) and that the largest stone was 131 tons, not 800 tons as claimed in ancient aliens.
    https://en.wikipedia.org/wiki/Pumapunku

    The wikipedia article is supported with references peer reviewed archaeology journal articles, such as The Construction and Reconstruction of Ritual Space at Tiwanaku, Bolivia (A.D. 500-1000) on JSTOR

    There is evidence on site of Copper metallurgy (specifically Cu-As-Ni) so I was wrong that this is purely stone-age technology.

    As I can see, many of the claims in Ancient Aliens are outright false.

    Totally on board with all of that.

    Not to mention a near-boundless supply of human labor, absent labor unions and laws.

    Thanks for digging all that up, something I should have done a long time ago. Now I can't watch Ancient Aliens anymore, lol!

    That show on Petra was awesome! I'll watch the whole thing when I get time. I'd also like to look for more info on Saksaywaman.
