In view of the growing difficulties ΛCDM-cosmologies to compete with recent highly accurate cosmological observations, I propose alternative model: Unicentric Model Observable UNiverse (UNIMOUN). The model relies on employing a new time-dependent -metric for GR field equations, which enables reversible phase transitions between normal compressible fluids and incompressible quantum superfluids, ...

The observation of primordial gravitational waves could provide a new and unique window on the earliest moments in the history of the universe and on possible new physics at energies many orders of magnitude beyond those accessible at particle accelerators. Such waves might be detectable soon, in current or planned satellite experiments that will probe for characteristic imprints in the polariz...

Nature abhors an infinity. The limits of general relativity are often signaled by infinities: infinite curvature as in the center of a black hole, the infinite energy of the singular big bang. We might be inclined to add an infinite universe to the list of intolerable infinities. Theories that move beyond general relativity naturally treat space as finite. In this review we discuss the mathemat...

We report on some aspects of our efforts to establish properties of the extremely faint galaxy population by applying our photometric redshift technique to the HDF and HDF–S WFPC2 and NICMOS fields. We find that cosmological surface brightness dimming effects play a dominant role in setting what is observed at redshifts z > 2, that the comoving number density of high intrinsic surface brightnes...

The highest energy cosmic rays observed possess macroscopic energies and their origin is likely to be associated with the most energetic processes in the Universe. Their existence triggered a flurry of theoretical explanations ranging from conventional shock acceleration to particle physics beyond the Standard Model and processes taking place at the earliest moments of our Universe. Furthermore...

Big Bang Nucleosynthesis (BBN) and the Cosmic Background Radiation (CBR) provide complementary probes of the early evolution of the Universe and of its particle content. Neutrinos play important roles in both cases, influencing the primordial abundances of the nuclides produced by BBN during the first 20 minutes as well as the spectrum of temperature fluctuations imprinted on the CBR when the U...

The present study sought to examine for how hope and sexual assault are involved in suicidal risk in a sample of 325 college students. Specifically, we were interested to examine whether sexual assault may play an additive as well as interactive role in the prediction of suicidal risk (viz., suicidal behaviors & reasons for living) above and beyond hope. Results from regression analyses indicat...

The Implicit Association Test (IAT; Greenwald, McGhee, and Schwartz, 1998) has become a widely used method of measuring individuals’ implicit preferences based on the speed of sorting words or images into respective categories in a computerized task. Age IATs have been used to ascertain implicit preference judgments towards young and old faces and to compare these ratings with explicit, self-re...

The consumer’s experience of self-customizing a product with a sales configurator can be a source of experience-related benefits for the consumer, above and beyond the traditionally considered utility of possessing a product that better fits his/her idiosyncratic needs. Although such experience-related benefits have been found by previous studies as increasing consumers’ willingness to pay for ...
