What's Fine - Tuning In Cosmology? (#1902) Duration: 29:00 STEREO TVG (Secondary audio: none)

Here's the claim: cosmic conditions that allow complex structures - galaxies, stars, planets, people - depend on a few "constants of nature" lying within tight ranges of values. But is fine-tuning valid?

What's Fine - Tuning In Physics? (#1903) Duration: 29:00 STEREO TVG (Secondary audio: none)

Why do the "constants of nature" - masses of subatomic particles and strengths of forces like gravity and electromagnetism - have the values they do? Does fine-tuning "cry out" for explanation?

Is The Anthropic Principle Significant? (#1904) Duration: 29:00 STEREO TVG (Secondary audio: none)

Here's the claim: conditions of the universe relate to the presence of observers. Does the Anthropic Principle convey deep insights? Or thwart science? For sure, it's often misunderstood and controversial.

Can Metaphysics Discern God I? (#1704) Duration: 29:00 STEREO TVG (Secondary audio: none)

How to think about God rationally, logically, profoundly, critically. We have no illusion that metaphysics can find God, but can a kind of progress be made?

What's Strong Emergence? (#1905) Duration: 29:00 STEREO TVG (Secondary audio: none)

Here's the claim: each level of the scientific hierarchy - physics, chemistry, biology, psychology - has its own special laws that can never be explained by deeper laws (physics). How can this be?

What Exists II? (#1906) Duration: 29:00 STEREO TVG (Secondary audio: none)

What's the ultimate stuff of reality? What's absolutely fundamental and non-reducible - the fewest number of categories within which every specific thing, of every general kind, can be classified?

Why Anything at All II? (#1907) Duration: 29:00 STEREO TVG (Secondary audio: none)

It's the ultimate puzzle. It's the haunting question. Why is there "something" rather than "nothing"? It seems impenetrable, uncrackable, unfathomable. But are there ways?
