, 2006 These lectures present a brief review of inflationary cosmology, provide an overview of the theory of cosmological perturbations, and then focus on the conceptual problems of the current paradigm of early universe cosmology, thus motivating an ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.ABSTRACT This article examines the historical displacement of Indigenous peoples in Venezuela, focusing on the links between indigenist policies and the exploitation of natural resources, particularly oil, throughout the 20th century. Using a combined historical and ethnographic approach, it demonstrates how the formation of the Venezuelan nation‐state

Inflationary perturbations and precision cosmology [PDF]
Physical Review D, 2005 Inflationary cosmology provides a natural mechanism for the generation of primordial perturbations which seed the formation of observed cosmic structure and lead to specific signals of anisotropy in the cosmic microwave background radiation. In order to test the broad inflationary paradigm as well as particular models against precision observations, it

A New Hilbert's Hotel Argument Against Past‐Eternalism
Analytic Philosophy, Volume 67, Issue 2, Page 145-153, June 2026.ABSTRACT This paper offers a new formulation of the “Hilbert's Hotel Argument” (HHA) which is superior to existing formulations because it (1) demonstrates that HH is logically impossible in the concrete world, (2) takes into account the need to consider the assumptions of HHA, and (3) offers a reply to an important objection concerning the validity of

Alignment of the Starlings: Learning With Generative AI
Future Humanities, Volume 4, Issue 1, May 2026.ABSTRACT I will argue that answers to normative questions concerning the place of generative AI in learning rest on answers to ontological questions regarding (1) precisely what is happening when a human ‘interacts’ with generative AI and (2) What is distinctive about organic learning as opposed to currently existing ‘machine learning’ (3) What is the ...

Pulsar timing array observations as possible hints for nonsingular cosmology
European Physical Journal C: Particles and Fields, 2023 Recent pulsar timing array (PTA) experiments have reported strong evidence of the stochastic gravitational wave background (SGWB). If interpreted as primordial gravitational waves (GWs), the signal favors a strongly blue-tilted spectrum.

Universe, 2023 Warm inflation has normalized two ideas in cosmology, that in the early universe the initial primordial density perturbations generally could be of classical rather than quantum origin and that during inflation, particle production from interactions ...
