Deepest underground structures

An evening pause: This is not a complete list, as it leaves out some very deep caves and mines that I myself have actually visited, but it truly does provide a sense of scale. It also mixes artificial structures with natural features.

Hat tip Cotour.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from me (hardback $24.95; paperback $14.95; Shipping cost for either: $5.00). Just email me at zimmerman @ nasw dot org.

    Unbelievable. That is a lot of mass above you. I guess I didn’t know that oil wells went down to 35,000 feet. I wonder if we will ever know how much oil is truly below our feet. Better bankrupt our civilization, because we’re not sure.

  • Peter Gent

    Oil wells going down to 35,000 feet proves oil is not a fossil fuel. It is produced naturally deep in the earth’s crust.

  • Cotour

    PG:

    “But is the O-14 really 49,000 feet deep? The short answer is no, because there is one little catch: directional drilling.”

    https://oilprice.com/Energy/Energy-General/The-Truth-About-The-Worlds-Deepest-Oil-Well.html

    “In terms of vertical depth, though, BP’s Tiber field in the Gulf of Mexico, drilled by the infamous Deepwater Horizon, became the location for the deepest oil well. The Tiber well’s depth – true vertical depth – was more than 35,000 feet.”

    I suspect that abiotic oil is the result, as is “Fossil” fuel-based oil and gas is essentially the same thing.

    Massive amounts of biological material being laid down over eons of time and driven down to depth through plate tectonics to where it is very deep and has been there for a long, long time. The earth has been biologically active for the last 3.5 billion years?

    I found the video very interesting in how it gave perspective and scale to something that is difficult to visualize.

    Good one Cotour. Thanks.

    Reminds me I watched a great movie on Amazon Prime called “Thirteen Lives” starring Viggo Mortensen and Colin Farrell and directed by Ron Howard about the 2018 rescue of the boys’ soccer team and their coach from a cave in Thailand.

    Like other commenters here I blame fairies.

  • GWB

    OK… two things…
    Why is the Turtle crying? (Tears of the Turtle Cave)
    Because he’s the bottom turtle. It is not really turtles all the way down.

    What are they observing 1,000m underground? Usually “observatories” are for looking at the stars. Kamioka Observatory looks like a contractor misread the blueprints and nobody questioned them on the cost overruns for digging a deep hole.

    Noticed some inconsistency with negative numbers appearing. Weird.

    All of that really cool.

    Well, in the case of mines, you’d need to blame kobolds. Fairies are lazy and don’t like to get their hands (or wings) dirty. Kobolds do real work. :)

  • Alex Andrite

    wow.
    I had to clear my “ears” due to multiple popping on the way down.

  • GWB: These deep underground observatories are for detecting neutrinos, which can pass through the Earth quite easily. By placing the neutrino detector deep underground you isolate it from other energy sources that could make detection difficult.

    I figured that might be what it was. But it should be labelled that way in the video. (Not your problem, obviously.)
    Also, I think that idea makes a materialistic assumption there are no “energy sources” in the Great Deep. The Old Ones are not forever content to be ignored. ;)

    Thank you. Name calling erupts from childish emotions that have no rational or logical expression except a bellow if fear.

    Obscenities are similar but are adult bellows that fail to consider the content and counter such with well thought out counterpoint thus the obscenity which is the bellower” reaction “you mean I have to think now and actually write my reasoned counterpoint- bullocks!”

  • Joseph Neal Sr: And thank YOU for your donation. It is most appreciated.

    I have found that by insisting people not use obscenities or insults they are forced to think, and thus the quality of the comments on this webpage have improved considerably. In other words, I demand they act like civilized mature adults, and after a short grumpiness most find the rules actually benefit both them and everyone else.

    Civilization. What a concept. We should all try it sometime.

  • Boobah

    I noticed that they showed another, further underground laboratory and that one was labelled as a neutrino observatory; Kamioka in particular does that, too, but they’re also a gravity wave observatory, and the work there and at other similar sites is how we’ve largely confirmed that, however gravity propagates, it seems to do so at the speed of light, since the gravity waves from events arrive at the same time as the light.

    Ahhhh, ok. Thanks.
