129 Fine tuned

Is the universe fine tuned for life to exist?

All the author managed to accomplish is to show that he doesn't understand the Fine-tuning argument. He has entirely missed the headline: There are 26 constants and dozens of other parameters that have values within a narrow range in order to produce a universe that could support life.

For example: If the gravitational constant (aka "big G") were stronger by one part in 10^40 (some physicists say 10^60), then the universe would have collapsed within seconds after the expansion began.

If the gravitational constant were weaker by one part in 10^40, then the expansion would have proceeded too rapidly for stars and galaxies to form. The universe would contain nothing more interesting than fundamental particles rushing away from each other forever.

In either case, there would be NO LIFE OF ANY KIND.
There are dozens of similar examples of fine-tuning that we could share. Many of them are told in the book entitled: A Fortunate Universe by two cosmologists: Geraint Lewis (an atheist) & Luke Barnes (a theist).

Good job, and while I agree with you, you must address what I am sure would be the theist's rebuttal to your claims. The universe is fine tuned to be the universe, but the Earth is fine tuned for our existence. Which (in the theist's mind) means undoubtedly that a designer created the exact conditions on Earth for his creations to exist. After all, he singled out the Earth from all the other heavenly bodies when he created them! He created all that other stuff out there wthout an intent to make humans there, and only made more specific conditions here where he was making mankind.
