A review by Peter D. Tillman
The book is written as a history of 20th century physics, from Einstein's theory of the relativity of
space & time (1905), to black holes, gravity waves and wormholes in the 90s. I found this a very engaging
approach. Thorne's writing is (usually) clear and direct, and he includes enough biographical tidbits and
anecdotes to keep the human juice in potentially dry topics.
Cosmic radio waves were discovered by a Bell Telephone engineer in 1932. Despite widespread publicity,
professional astronomers weren't very interested -- the first radio-telescope was built by a radio "ham",
in his mother's back yard in Illinois, in 1940. The first professional radio-telescopes weren't built until
after WWII, in England and Australia; Americans didn't become competitive until the late 50s.
Thorne has a fair command of Russian, which gave him an "in" when the USSR started allowing scientific
contacts in the post-Stalin era. Now that Russia is such a mess, we forget that the Soviets produced a
bunch of world-class scientists and engineers 2, from the 30s on -- including some of the
best physicists since Einstein.
Dr. Thorne, the Feynman Professor of Physics at Caltech, is
best known to the general public for his 1988 wormhole "time machine" proposal. Press coverage included a
photo of the author doing physics in the nude on Mt. Palomar. "Embareassing," but didn't hurt the book
sales. The wormhole work grew out of a request from Carl Sagan for a plausible FTL transport scheme for his
1985 science-fiction novel Contact (which I recommend). Sagan's request made Thorne realize the value of
thought experiments that ask, "What things do the laws of physics permit an infinitely advanced civilization to
do, and what do the laws forbid?" This style of speculation by world-class scientists has become popular (and
somewhat respectable) in the last decade, and has resulted in some very stimulating reading, such as K. Eric
Drexler's Engines of Creation (1986), and Hans Moravec's Mind Children (1988) and Robot (1999).
My last exposure to formal physics was two painful undergraduate courses (mumble) years ago. Since then I've
kept up at roughly a Scientific American level or below (plus I read a lot of science fiction).
I think I'm close to the author's aim-point for his potential audience.
I found some of the physics tough going, but these sections can be safely skimmed without losing the thread
of his arguments. I read most of the book in two sittings -- it's surprisingly gripping. So... don't put off
reading Black Holes any longer!
2 -- along with some remarkable pseudo-science. Iosif Shlovsky tells of many such projects in his very
entertaining Five Billion Vodka Bottles to the Moon (1991).
