    Mean Origin
AI Thread Summary
The discussion revolves around the concept of "origin from nothing" in quantum cosmology, highlighting two main approaches: quantum tunneling from nothing and the no boundary proposal. A recent paper by Brown and Dahlen critiques both approaches, suggesting that the Hawking-Turok instanton does not facilitate the quantum creation of a universe. The conversation emphasizes the complexity of defining "nothing," with some participants arguing that true nothingness, devoid of any physical properties, is unphysical and cannot lead to creation. Theoretical models are proposed that involve absolute nothingness, which would require a reevaluation of the laws of physics and the nature of existence itself. Ultimately, the discussion reflects ongoing debates in cosmology about the origins of the universe and the implications of quantum mechanics.

x = y.
Then x2 = xy.

"does not compute"... x2 = xy

This has become silly. Thread closed.
