Conscious Choice cover

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.

Hang Son Doong (Mountain River Cave) in Vietnam

An evening pause: As I have been out today doing survey work for a cave project of which I am the cartographer, I thought this video of Hang Son Doong (Mountain River Cave) would be appropriate.

Note that this cave is definitely not the largest in the world, as is often claimed. It appears to have the largest single room of any known cave, but the cave itself is relatively small at about four miles, compared for example to Mammoth Cave in Kentucky, which is the world’s longest cave at 400 miles.

    Would it be largest based on the volume of space inside? It certainly dwarfs its visitors. The photos are breathtaking.

  • It is a breathtaking cave, but in terms of volume it doesn’t even come close to Mammoth, or other large systems that top a hundred miles. See the long cave list for the world and the U.S. long cave list.

    I’m surprised by how many caves on this list I’ve been in, and even more surprised by how many I’ve never heard of. Also, should caves that are entirely under water be included, or be on a separate list?

    Yes, I see now that Mammoth is the colossus of caves, no contest.

    I’m shocked to find that I live about 3 hours from the 11th deepest cave in the U.S. A very cold, wet one, but apparently very nicely decorated. A relative once walked to its entrance during a much longer back-packing excursion in the Seven Devils, but I’ve never heard anyone else even mention its existence.

    Really, you have the most interesting avocation.
