Will LQG explain the constants?

Click For Summary
The discussion centers on the idea that certain fundamental constants in physics, like the fine-structure constant and the cosmological constant, appear finely tuned for life, prompting questions about their origins. Lee Smolin's "cosmic natural selection" (CNS) theory proposes that these constants could evolve through a process analogous to Darwinian natural selection, where values that favor black hole production enhance the universe's reproductive success. CNS is presented as a falsifiable model, unlike the anthropic principle, as it predicts specific outcomes that could be tested against observations. The theory suggests that if certain astronomical measurements contradict CNS predictions, it could be disproven, emphasizing its scientific validity. Overall, the CNS principle offers a novel framework for understanding the constants of nature while acknowledging the need for further research and validation.

I asked because I don't have $100 to spend on a textbook right now, even if its a classic that I've skimmed in a college bookstore a few times and longed to buy. Being a professor doesn't pay nearly as well as being a full time practicing lawyer.

we are both in the same boat Ohwilleke, sorry to say. But we must both be close to university libraries! Let's both get over to the physics departmental library and look this up----I just have secondhand references too and it is not really satisfactory.
