The lecture: (from 2013)
Note: there is a period of 19 minutes of Q&A at the end of the lecture.
About the speaker:
Summary:
- It used to be true that most of the great scientists were believers in God
- But now science has advanced and we have better instruments – is it still true?
- Today, many people believe that science has shows that the universe and Earth are not special
- We used to believe that the Earth was the center of the universe, and Darwin showed we are not designed
- The problem with this view is that it is based on old science, not modern science
- Three topics: origin of the universe, fine-tuning of the universe, the Rare Earth hypothesis
Experimental evidence for the origin of the universe:
- #1: Hubble discovered that the universe expands because of redshifting of light from distant galaxies
- #2: Measurements of the cosmic microwave background radiation show the universe had a beginnning
- #3: Measurements of the light element (hydrogen and helium) abundances confirm an origin of the universe
- The best explanation for an absolute origin of space, time, matter and energy is a supernatural cause
Experimental evidence for the design of the universe:
- #1: The amount of matter: a bit less = no stars and galaxies, a bit more = universe recollapses
- #2: The strong force: a bit more = only hydrogen, a bit more = little or no hydrogen
- #3: Carbon resonance level: a bit higher = no carbon, a bit lower = no carbon
Experimental evidence for galactic, stellar and planetary habitability:
- #1: Galaxy: produces high number of heavy elements and low radiation
- #2: Star: long stable lifetime, burns bright, bachelor star, third generation star (10 billion years must elapsed),
- #3: Planet: mass of planet, stable orbit, liquid water, tectonic activity, tilt, moon
Naturalistic explanations:
- Humans evolve to the point where they reach back in time and create finely-tuned universe
- Eternally existing multiverse
Hawking and Mlodinow response to Rare Earth:
- There are lots of planets so one must support life
- Odds of a planet that supports life are low even with 10^22 planets
Hawking and Mlodinow proposal of M-theory multiverse:
- There is no experimental evidence for M-theory being true
- M-theory is not testable now and is not likely to be testable in the future
- But science is about making testable predictions, not about blind speculation
Hawking and Mlodinow no-boundary proposal:
- This theory requires the laws of physics to exist prior to the universe
- But where do you get laws of physics before there is any physical world?
- There is no experimental evidence for no-boundary proposal
- All the evidence we have now (redshift, CMBR, H-He abundances) is for Big Bang
What science has revealed provide abundant evidence for a transcendent Creator and Designer
