There  are  various  levels  of  regulation.  The  "highest"  level  is  the  statutory  regulation  of  osteopathy  and  chiropractic. The General  Chiropractic  Council  (GCC) has  exactly  the  same  legal  status  as  the  General  Medical  Council  (GMC).  This  ludicrous  state  of  affairs  arose  because nobody in John Major's government had enough scientific knowledge to realise that  chiropractic, and some parts of osteopathy, are pure quackery.    The  problem  is  that  organisations  like  the  GCC  function  more  to  promote their  discipline  rather  than  regulate  them.

The book was released in 2008 and explores the various ways in which the human race could be rendered extinct by astronomical phenomena. It covers various astronomical events, such as asteroid impacts, supernovae explosions, solar flares and gamma ray bursts. Plait explains the science behind each event and the odds of it occurring in our lifetimes.

Astronomical Event	Estimated Probablity of Causing Death	Commentary
asteroid impacts	1 in 700,000 in a human lifetime	May be able to prevent impact.
solar flares	0 probability directly attributed to event	Energy from eruption may damage power grid on a global scale which may cause many deaths. Developing robust power grids may prevent massive failure.
supernovae explosions	1 in 10,000,000	Death from Ozone depletion and radiation if the supernova is less than 25 light years from Earth.
gamma ray bursts	1 in 14,000,000	Death from radiation and ozone depletion from burst 7,000 light years away if the Earth is inside the path of the energy beam.
Heat death of the Universe	Inevitable	Any remaining objects unlikely to interact after the decay of protons and the evaporation of black holes. The estimated time scale for this era is beyond 1092 years.

Background

The author stated during an interview that one of the reasons for writing the book was that "the Universe is incredibly inhospitable, yet we have this planet that’s doing OK by us. Another is that the Universe is incredibly cool and interesting. Black holes are really fun to think about. Actually, most of this is mind-stretching and fun. What happens to the Sun after 100 quadrillion years? One hundred octillion? A googol? He also said that the reason for using doomsday scenarios was to take a scientific viewpoint make it like a roller coaster or horror movie to make it fun and exciting. The stories were not to scare people out of the their pants but make it cool to read about it.
