Hanslune Posted April 24, 2019 #1 Share Posted April 24, 2019 https://www.theatlantic.com/science/archive/2018/04/are-we-earths-only-civilization/557180/?utm_source=facebook&utm_medium=social&utm_campaign=share&fbclid=IwAR0DreRviYKj5ryN-2y79RzcIKktM4I4RzJzkl-skeW6MreGxlvLHwmaO7I This is a non-woo look at how we would/could detect a Palocene non-human industrial civilization Quote It’s not often that you write a paper proposing a hypothesis that you don’t support. Gavin and I don’t believe the Earth once hosted a 50-million-year-old Paleocene civilization. But by asking if we could “see” truly ancient industrial civilizations, we were forced to ask about the generic kinds of impacts any civilization might have on a planet. That’s exactly what the astrobiological perspective on climate change is all about. Civilization building means harvesting energy from the planet to do work (i.e., the work of civilization building). Once the civilization reaches truly planetary scales, there has to be some feedback on the coupled planetary systems that gave it birth (air, water, rock). This will be particularly true for young civilizations like ours still climbing up the ladder of technological capacity. There is, in other words, no free lunch. While some energy sources will have lower impact—say solar vs. fossil fuels—you can’t power a global civilization without some degree of impact on the planet. 5 1 Link to comment Share on other sites More sharing options...
Earl.Of.Trumps Posted April 24, 2019 #2 Share Posted April 24, 2019 Interesting theory, @Hanslune, but just how can this all be detected? According to your link, once you go past 2.6 million years there is nothing whatsoever left. Link to comment Share on other sites More sharing options...

According to your link, once you go past 2.6 million years there is nothing whatsoever left. I believe they were talking about older layers that are still on the surface. The older layers are still there just buried. We find dinosaur and even earlier fossils in much older layers. Stromatolites were discovered in metasedimentary rock in Greenland 3.7 billion year. old. https://en.wikipedia.org/wiki/Stromatolite 4 Link to comment Share on other sites More sharing options...
jaylemurph Posted April 24, 2019 #4 Share Posted April 24, 2019 I hate to be picky, but history refers to the existence of written texts within a culture. It only goes back a few thousand years, a lot less time than the article is discussing. —Jaylemurph 3 Link to comment Share on other sites More sharing options...

+Not A Rockstar Posted April 25, 2019 #6 Share Posted April 25, 2019 I find this very exciting, as I am intensely interested in the question of if there was a civilization (or several) before we came along. That science is looking and defining what would have to be found if the answer is yes gives me more hope for a real answer, one way or the other. I do have one question about the def of a civilization. This steps it out into being world wide, and I never heard that as a requirement before. Technically, could it not rise and fall on one continent and still be a civ? 2 Link to comment Share on other sites More sharing options...

Yeah an in our civilization's case, cut gems and misplaced fossils. I live in a place where lava might someday flow over my house. If so an archaeologist in 50,000,000 AD would find a layer with stone tools from a variety of materials and tools sets, pottery shards and fossils from all kinds of eras. That would be magnificent confusion! Edited April 25, 2019 by Hanslune 4 1 Link to comment Share on other sites More sharing options...

You are correct the size of civilization doesn't need to be world wide but being wide spread might make it a lot easier to detect - we've been lucky to find a number of the current easiest sites.= Catal huyuck, GT and others. 2 2 Link to comment Share on other sites More sharing options...

So they would find hundreds of rocks, fossils and various stone and metal artifacts from all over the U.S., Africa and Asia under water and lava. 2 Link to comment Share on other sites More sharing options...

Tatetopa Posted April 25, 2019 #20 Share Posted April 25, 2019 Its a good paper. Thanks. Don't tell Graham Hancock. What would one of our cities leave behind in 50 million years? A lens of material in sedimentary rock or under a lava flow maybe? A few square miles of silica, iron oxides, aluminum oxides a scattering of copper, gold rare earths, diamonds, and other anomolies maybe? No buildings, at least on earth, just a tell tale smear of non-natural agglomerations of elements. 2 Link to comment Share on other sites More sharing options...

Yeah, a thin layer that would be noticeably 'unnatural' with a mix of stuff that nature just couldn't produce or place all together, maybe long half-life radioactives too. 2 1 Link to comment Share on other sites More sharing options...

Given that we still see people believing GH's statement that the Piri Reis map shows Antarctica I suspect that people stating, as fact, that their was an invisible Native American civilization in NA - which left no traces - for decades to come.

Piney Posted April 25, 2019 #23 Share Posted April 25, 2019 @Hanslune Yeah, but they left it covered up with plant life. Not too many know about it and there are no rangers or guides.
