Giant Pyramid Buried in Indonesia Could Be The Oldest in The World
  • So, this dating is extremely controversial. The single researcher who claims it has not yet published those findings, and the dates vary wildly (from 9,000bp to 20,000 bp) from interview to interview. No material culture has been found at the site suporting dates older than 2,000bp. No source culture for the 9,000 to 20,000 date has been identified.

    Enen if the dating is verified at somewhere inthat range, all it demonstrates is that something was at the site at that time (if the dating material is from a fire, it shows someone lit a fire there, for instance). Considering there were tool-making hominids in Sundaland 1.5 million years ago, and homo sapians 45,000 bp, it would be interesting, but not revolutionary, to find some presence at the site. Much more and varied evidence would be required to indicate that this was a megalithic work predating Gobekli Tepe.

    As a second note, also important: Gunung Padang is not a pyramid. Its an andesite hill which naturally fractures in to columns and terraces. Some of the terraces have been leveled off by trimming and filling, but that is a very different task from transporting stone to build a pyramid or other free-standing megalithic structure.

  • When we allow aparthied states to comnit genocidal acts without protest, we signal that other countries should not interfere should our own state turn to aparthied and genocide.

    Its either ok for no one or its ok for everyone

  • Cockney and Queen's English have all but disappeared among young people – here's what's replaced them
  • This is just another study confirming what has been known for years. MLE is the multicultural expansion of cockney. Much of the accent survives, but has been modified by exposure to many cultures. Its been identified as the dominant native london accent foresomething like a decade.

  • Scientists Successfully Simulate Backward Time Travel with a 25% Chance of Actually Changing the Past
  • Ok, so, this is in the context of closed timelike curves. This is a thing which appears in the math of general relativity. It has never been observed in real life, and may disappear if we ever have a reconciliatian of quantum mechanics and gravity.

    The study was a computer simulation of "what if we had some particles in a closed timelike curve and could mess with them", and there is no suggestion of this being applicable or even possible in the real world.

  • Roots of Mother Appalachia
  • Mountain bases can support a lot. Everest is not terribly tall from its base, true, but Denali is 5500 meters from base to top and Mauna Kea rises to 10000 meters over base.

    Its also a bit of an incorrect picure to think of the interior magma as a liquid. It can flow, but it can also sieze up or crack. Its an in-between, like corn starch and water.

  • Roots of Mother Appalachia
  • What we see now are the ancient roots. Before the continental colision, there was a sea and subduction zone. This gave us sandstones, diorite, and granite... All of which were crushed at incredible pressure and temperature by the continental collision. At the deep roots of the mountains, this transformed the rock into gneiss, marble, and other extremely hard rock. Additionally, the forces were so great that the very bottom melted and became fresh granite.

    All of these stones are very hard and resistant to erosion, and are what we see todayas the Appalachians

  • Roots of Mother Appalachia
  • Its indirectly gravity. The taller the mountain, the more eroding force can be pleced on it. Water travels faster and therefore cuts deeper.

    Everest is still uplifting fairly quickly at 1mm a year, but its also eroding at roughly the same pace and won't get significantly taller than it is now. The same is true for the rest of the Himalaya as well, the whole range is eroding at a very high pace.

    The Himalaya are home to some very spectacular canyons, including the largest canyon above water. The geology there is on full display and incredible.

  • Roots of Mother Appalachia
  • I have started daydreaming of a career change to geology. There are just so many unanswered questions and its not like space or physics were these questions are tinyor super far away. You can just walk upto a geologic puzzle and hit it with a hammer.

  • Roots of Mother Appalachia
  • One nit, pangea wasn't the first supercontinent, we know of at least two, maybe three before it. The stone of the Adirondak mountains was formed as part of the Grenville mountains, which were built by a suprecontinent 1.5 billion years ago (the adirondaks got tall be'ause of a much more recent, unrelated thing, but their stone is very old). The Grenville runs from Hudson Bay to Texas

  • Roots of Mother Appalachia
  • Completely unrelated. North and south america wern't attached when the appalachians were tall. The Andes are formed by an ocean plate (the Nazca plate) dragging as it is sucked under south america. They are tall, and still growing taller.

  • Had to say goodbye to my little man recently, here he is watching the birds

    He was seventeen, deep into kidney disease. The ten years I got with him were such a joy.

    I thought this is a great example by using a trick bicycle. Also shows that its not a function of speed.

    New feed and top one hour dominated by lemmit.online

    I like to keep up with fresh content and new stuff, so I usually sort by new, top hour, or top 6 hour. The latter is usually good, but if course limiting. I find the the first two, however, are dominated by posts from lemmit.online. For those unfamiliar, this is an instance used by the lemmit bot to repost content from reddit. While some of the content is interesting, a large chunk of it is discussion posts where the op is on a different network entirely, such as aita or programming help requests.

    I don't find these posts to be very... Quality. If it were a possibility, I would block this instance entirely. How do others feel about it? Am I taking too strong a stance? Is this content a positive contribution?

    Barefoot running shoes with long lasting soles?

    I've been running in barefoot shoes for several years, and xero hfs for the last two years. I find that they wear out rather quickly, in the range of 230-250 miles

    What brands have longer lasting materials for the sole? Are there any that could stretch to 300 miles and beyond?
