I just finished reading the book Will The World End in 2012? by Dr. Raymond Hundley. At 184 pages, it's a fast read. The author examines the top 10 theories as to why the world is supposedly going to end in 2012, or more specifically for some theories, on Dec. 21, 2012.
Each chapter begins with a (slightly cheesy, IMO) scenario in which that prediction occurs in real life. And although there are 10 theories, as the author notes in the eleventh chapter, (entitled Final Evaluations), only four of the theories hold any scientific credence whatsoever (Writing as a Christian, the author includes Christ's return to Earth as a plausible theory.) The remaining "realistic" three reasons for the earth's demise include:
-- massive solar flares hitting Earth, triggering earthquakes, tsunammis, etc. This theory is backed by the best scientific evidence. Scientists at NASA and other respected institutions are expecting a peak of solar flares in 2012; the question is whether they will do any damage.
-- a malfunction of the particle collider in Europe (unknown probability, obviously.)
-- super-volcano eruptions (including the one under Yellowstone) due to the Earth's core heating up (also of uncertain likelihood)
I was personally annoyed at how the author gave credence to some really outlandish theories. I suppose the goal was to include every possible 2012 theory, but as I read, I found myself mentally checking off the truly ridiculous theories as rubbish before the author even gave his conclusion at the end of each chapter.
In conclusion, I found this book to be somewhat interesting, but I did not feel it left me as a reader any wiser or informed than I was before, (except for gaining useless knowledge about wacky 2012 theories.) However, some people are apparently really weighed down with worry and fear about 2012, so for them, this book would probably provide a much-needed dose of reality!
In conclusion (again), my personal opinion is that Jesus did not say "Watch and pray," and "No one knows the hour or the day" for nothing. Christians who adhere to the belief that the world is ending on 12/21/12 should (IMO) maybe read their Bibles a little closer. :)
