What does it mean to say that the universe is fine tuned for life?
The characterization of the universe as finely tuned suggests that the occurrence of life in the universe is very sensitive to the values of certain fundamental physical constants and that the observed values are, for some reason, improbable.
What does fine tuned mean in physics?
In theoretical physics, fine-tuning is the process in which parameters of a model must be adjusted very precisely in order to fit with certain observations. The heuristic rule that parameters in a fundamental physical theory should not be too fine-tuned is called naturalness.
What is Swinburne’s fine tuning argument?
Swinburne will argue that ‘intelligent life is something which a creator God would have the power and abundant reason to bring about, and so a pheno- menon which, if he exists, would be quite likely to occur ‘, so that P(e\h&k) is quite high; but intelligent life is ‘something not in the least likely to occur except as …
What is the fine-tuning argument in philosophy?
The Fine-Tuning Argument, to be abbreviated by FTA in what follows, claims that the present Universe (including the laws that govern it and the initial conditions from which it has evolved) permits life only because these laws and conditions take a very special form, small changes in which would make life impossible.
What is fine-tuning in CNN?
Fine-tuning is a super-powerful method to obtain image classifiers on your own custom datasets from pre-trained CNNs (and is even more powerful than transfer learning via feature extraction). If you’d like to learn more about transfer learning via deep learning, including: Deep learning-based feature extraction.
What is fine-tuning CNN?
What is the definition of fine-tuning?
: to make small changes to (something) in order to improve the way it works or to make it exactly right. See the full definition for fine-tune in the English Language Learners Dictionary.
What does fine-tuning a network mean?
Fine-tuning is a way of applying or utilizing transfer learning. Specifically, fine-tuning is a process that takes a model that has already been trained for one given task and then tunes or tweaks the model to make it perform a second similar task.
Is the fine tuning argument true about the universe?
If you’re not familiar with the fine-tuning argument, it goes something like this: The parameters for life are so finely tuned that if they were tweaked ever so slightly, all life would cease to exist, and the universe would be too hostile for life, if it existed at all.
How is the fine tuned Universe related to creationism?
Various possible explanations of ostensible fine-tuning are discussed among philosophers, scientists, theologians, and proponents and detractors of creationism. The fine-tuned Universe observation is closely related to, but is not exactly synonymous with, the anthropic principle, which is often used as an explanation of apparent fine-tuning.
Is the anthropic principle a fine tuned universe?
Carbon and oxygen. Critics also suggest that the fine-tuned universe assertion and the anthropic principle are essentially tautologies. The fine-tuned universe argument has also been criticized as an argument by lack of imagination, as it assumes no other forms of life, sometimes referred to as carbon chauvinism.
Is there a condition of no fine tuning for life?
Section 5 turns from fine-tuning for life to the criterion of naturalness —a condition of no fine-tuning in a rather different sense which applies to theories in quantum field theory and plays a large role in contemporary particle physics and cosmology. 1. Fine-Tuning for Life: the Evidence
