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.

Have scientists produced a speck of solid metallic hydrogen?

Scientists using a diamond vise think they have produced the first speck of solid metallic hydrogen, potentially capable of being a superconductor at normal temperatures.

While the scientists who performed the experiment believe they have succeeded, others are skeptical. Read it all. This is quite fascinating research.

    The new Feishman and Pons?

    If this is indeed true in all of its aspects, what mechanism is proposed that would allow metallic hydrogen under such intense pressure to remain in its metallic state sans the pressure?

    ….”what mechanism is proposed that would allow metallic hydrogen under such intense pressure to remain in its metallic state sans the pressure?”

    The same mechanism that lets a diamond stay in its metastable state when the temperature drops and the pressure is let up and the thing stays a diamond instead of going back to graphite, until you raise the temperature above the critical point again, of course.

    Metastable states are tricky that way.

    Sometimes the critical temperature is well *below* room temperature. Sometimes they are several thousand degrees Kelvin.

    Ya dinna knooo, till you try it laddee!

    They haven’t dropped the pressure yet. I assume they’ll try that first. They haven’t raised the temperature yet.

    They may be just a wee bit nervous!

    Slightly off subject but related to hydrogen and cold … an interesting read
