Tytuł:: Kwantowe stworzenie Wszechświata
Quantum creation of the Universe
Autorzy:: Heller, Michał
Powiązania:: https://bibliotekanauki.pl/articles/690622.pdf
Data publikacji:: 2007
Wydawca:: Copernicus Center Press
Tematy:: Hartle-Hawking model
inflation
quantum creation
Opis:: The paper discusses the idea of quantum creation of the universe. After a few remarks concerning inflationary models and Tryon's idea of the world's origin as a fluctuation in the preexisting vacuum, the Hartle-Hawking quantum creation model is presented. Its structure and assumptions are discussed, and interpretative difficulties related to the mechanism of 'quantum creation' pointed out.

Tematy:: singularity

Stephen Hawking
Georges Lemaître
Opis:: This paper puts forward the problem of singularity – one of the most important issues in contemporary cosmology. Firstly, the history of “singularity” concept and basis of Penrose’s and Hawking’s theorem of singularity are discussed. Secondly, the problem of singularity is presented as a genesis of search of quantum theories of the beginning of the Universe, in which the concept of singularity is not present. One sophisticated concept of Hartle and Hawking is presented, in particular the authors’ methodology is described. The paper shows many possible philosophical problems which are connected with quantum cosmology.

Tytuł:: What does it mean ‘to exist’ in physics?
Autorzy:: Heller, Michał
Powiązania:: https://bibliotekanauki.pl/articles/691082.pdf
Data publikacji:: 2018
Wydawca:: Copernicus Center Press
Tematy:: existence
ontology in the sense of Quine
ontology of physics
Hartle-Hawking quantum creation model
nothingness in physics
Opis:: Physical theories give us the best available information about what there exists. Although physics is not ontology, it can be ontologically interpreted. In the present study, I propose to interpret physical theories à la Quine, i.e. not to speculate about what really exists, but rather to identify what a given physical theory presupposes that exists. I briefly suggest how Quine’s program should by adapted to this goal. To put the idea to the test, I apply it to the famous Hartle–Hawking model of the quantum creation of the universe from nothing, and try to discover what kind of nothingness the model presupposes. I also make some remarks concerning ontological commitments of the method of physics itself.
