Presentation Transcript

  1. The laws of Physics and the Big Bang • Conservation of Energy (Where did all this come from?) • The Second Law of Thermodynamics (What about entropy)

  2. Draw a Card Probabilities • Pick a card • 10 decks with different backs each deck given to different student • Each student picks a card randomly and independently from their deck

  3. Results Shown Below • The odds of the students picking this set of cards each with a different back are: • 1:5210 or one in five hundred twenty billion • How did they ever do it, MUST be rigged! • NOT rigged all sets are equally amazing and boring

  4. Design a Universe Probability • Infinite (or at least VERY large) number of possible values for physical constants • All values have a very low probability of occurring for each constant • All combinations have an even lower probablity • All values and combinations are equally amazing and/or boring

  5. Design a Universe Probability and Simplicity • All values and combinations are equally amazing and/or boring • OR are they? • Conservation Laws • Mass/Energy • Momentum (linear and angular) • Charge • Lepton number • Baryon number • Symmetry • Simplest possible universe (AND most likely)! • Stenger, V. J. (1997). Intelligent Design: Humans, Cockroaches, and the Laws of Physics. Retrieved December 8, 2008, From www.talkorigins.org/faqs/cosmo.html

  6. Physical Constants and tuning for life (Design a Universe Suitable for Life) • Anthropic Principle and Circular reasoning • Physical constants compatible with life • We are here • All measured values compatible with life . . . • Variation of Constants Vs. Stellar Lifetime (see next slide)

  7. Distribution of stellar lifetimes for 100 random universes in which four basic physics constants (the proton and electron masses and the strengths of the electromagnetic and strong forces) are varied by ten orders of magnitude around their existing values in our universe. Otherwise, the laws of physics are unchanged. Note that in well over half the universes, stars live at least a billion years. • Stenger, V. J. (1997).

  8. Testability: The Hallmark of Science • Physical ability test • Testable means falsifiable • Realistic falsifiable experiment • Irreducible complexity • Evolution • Intelligent Vs natural (designed rock?) • ID is inherently NOT falsifiable • ID is NOT science

  9. Failures of Science to Explain? • Fossil intermediates (Johnathan Wells – ID advocate, Author of Icons of Evolution and HIV/AIDS denier) • Evolution of Human immune system (Michael Behe in Darwin’s Black Box) • Fish Tetrapod fossil intermediates (Phillip Johnson Founder of Modern ID Movement and HIV/AIDS denier) • Will science be able to explain: • Origin of the Universe? • Origin of life? • Evolution of RNA/DNA? • I Don’t know, but I wouldn’t bet against it!

  10. Dangers of Intelligent Design • Doctors, Scientists, and Engineers that: • Diagnose and treat diseases based on knowledge of how the natural world works • Design planes, bridges, etc, based on the way in which the natural world works • Understand the way in which the universe operates • Continue to search for natural ways to cure disease • Continue to Search for new answers to how the universe works • OR • Attribute the way in which the natural world works to a designer • Stop looking for the answer since they already know it!

  11. The BIG Question • Do I believe in (an) Intelligent Design(er) • Yes! (Surprise) • GOD (Bigger Surprise) • But . . . • Religion is not Science! (neither is poetry, love, anatomy, or history. The first two are good, I’m not so sure about the last two.) • I would never hang my belief in God on science! • Intelligent Design is not science, but if used to bolster Religion it is BAD theology!
