Expansion Of Space

We describe the effect of the expansion of space on the wavelength of the light beam in a Fabry-Pérot interferometer. For an instrument such as the Laser Interferometer Gravitational-Wave Observatory (LIGO), which has high sensitivity and a long period of light storage, the wavelength λ L of laser photons are redshifted due to the expansion of space in each cavity by an amount δ λ given by δ λ / λ L = H 0 τ s ≈ 8 . 8 × 10 - 21 , where H 0 ≈ 2 . 2 × 10 - 18 s - 1 is the Hubble constant and τ s ≈ 4 ms is the light storage time for the cavity. Since τ s is based on the cavity finesse F which depends on the laser beam full width at half maximum (FWHM) δ ω of each cavity, we show that a difference in finesses between the LIGO arm cavities produces a signal h H ( t ) at the anti-symmetric output port given by h H t = 2 a 1 H 0 1 δ ω X t - 1 δ ω Y t , where δ ω X ( t ) and δ ω Y ( t ) are the beam FWHM at time t, respectively, for the X and Y arm cavities and a 1 is a beam proportionality constant to be determined expermentally. Assuming a 1 ≈ 1 , then for cavity beams FWHM of δ ω ( t ) ≈ ( 523 . 2 ± 31 ) rad . s - 1 the output signal has the range ∣ h H ( t ) ∣ ≤ 1 × 10 - 21 , which is detectable by advanced LIGO.

Expansion Of Space

One of the theatre and performance conventions that has been challenged by the application of technology is that of space. Theatrical space has been “expanded” through the application of technology and its artefacts. However, it is not reallyclear what is meant by “expansion”, as it means different things according to different authors and these divergent meanings often lead to misunderstandings. In this article, I will demonstrate the need for a more nuanced understanding of what the expansion of theatrical space means and its impact on the concept of spectatorship. The analysis will be based on three distinct forms of digital performance where spatial expansion has been an issue; these are three categories that also mark the heterogeneity and dynamism of the convergence of performance and technology: multimedia performance, telematic performance and pervasive performance. Through an analysis of specific cases across the categories, I aim to show how the expansion of space implies a more participatory stance in the role of the spectator.

Expansion Of Space

The present study aims to investigate the area of conflict between the decline and the expansion of communication options in regional and minority languages, which has increasingly been brought into the focus of attention by the new digital media. This topic will be discussed based on the example of Occitan in the southern third of contemporary France where the langue d’oc continuously forfeits its territory.Besides the real topographic decline, the internet offers the Occitan a new virtual sphere of communication. By contrasting the concrete decline of space with the virtual expansion of space, the following article aims to illustrate the importance of the border, more precisely the border demarcation, with regard to the possibilities of communication of the Occitan language.

Expansion Of Space

A long standing problem in paleontology is the presence of giant arthropods during the so-called carboniferous era. The same difficulty occurs for the size of plants at the same period. We devise a possible answer to this question entirely different from the theories developed until now, based on the hypothesis that the size of atoms is decaying for very large times and the dimensions of polymers such as chitin and cellulose, containing expansible holes, are decreasing more slowly than rigid materials such as metals, alloys, composite materials and stone. Incidentally, this hypothesis might also give an alternative statement to the expansion of space.
