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

• p21-23 Goddard, no mention of Roswell work

• p25 3000 V-2s, 9000 Allies deaths, more slave labor deaths building them

• p32 unnamed congressman "no buck rogers, no bucks" ... and no citation, perhaps POOMA.

• p36-xx NASA SLS, Bezos moon, 6% B
• p43 ice on moon

  • https://www.science.org/doi/epdf/10.1126/science.330.6003.434

  • LCROSS, Cabeus crater near lunar south pole, blasted by spent rocket stage, 6% by mass, top meter or two
  • prior radar mistaken

• p47 "The astronauts would have to adjust to the lower gravity on the moon"
  • er, no, near-one-gee may be necessary for health, the Moon is 83% zero gee.
  • also ignores effects of abrasive lunar dust on equipment

• p60 Dawn asteroid mission orbiting Ceres since 2015 (hydrazine depleted 2018)
