CAN WE SEE NAKED SINGULARITIES?

Can we see Focus

The purpose of this study was to determine whether the visual modality is useful for the perception of prosody. An audiovisual corpus consisting of four focus conditions (subject, verb, object focus and broad focus) was recorded from a male native speaker of French. A preliminary production study showed that there are visible correlates of contrastive focus in French a) increase in lip area and...

[Can we see pain?].

Pain is a highly subjective experience that is difficult to measure objectively due to its varied expression. It is defined as a complex sensory-emotional experience, it is modulated by cognitive factors and involves a broad neural system. Functional neuroimaging has helped to define that neural circuit involved in the perception, modulation and response to painful experience, both in healthy c...

Gravitational collapse and naked singularities

Gravitational collapse is one of the most striking phenomena in gravitational physics. The cosmic censorship conjecture has provided strong motivation for researches in this field. In the absence of general proof for the censorship, many examples have been proposed, in which naked singularity is the outcome of gravitational collapse. Recent development has revealed that there are examples of na...

Naked Singularities and Quantum Gravity

There are known models of spherical gravitational collapse in which the collapse ends in a naked shell-focusing singularity for some initial data. If a massless scalar field is quantized on the classical background provided by such a star, it is found that the outgoing quantum flux of the scalar field diverges in the approach to the Cauchy horizon. We argue that the semiclassical approximation ...
