The Future of Humanity
Terraforming Marsm Interstellar Travel, Immortality, And Our Destiny Beyond Earth
Michio Kaku 2018, 629.455 KAKU Cedar Mill Library
The media-canonical future, as channeled by a 70yo pop-sci media gadfly and former theoretical physicist. Many acknowledgements of other non-engineer non-inventor non-entrepreneur media pundits. Much focus on "ick factor" reactionary barriers. I mostly skimmed the book, looking for any surprises.
- p1 Prologue, Toba volcanic explosion 75 kya.
p5 Sun expansion to 1.2 AU 5Gy from now
- wp mass loss will expand Earth's orbit to 1.5 AU, tidal drag will reduce it, luminosity will increase 2700x
this assumes no Oort object flyby orbit astroengineering
unnecessary for the expansion of life towards a Kardashev 2 civilization, but given all that energy, why not?
p20 Tsiolkovsky aside
