This preprint is the final part of a series of preprints devoted to the study of unsolved problems in classical physics (interference paradoxes, differences between antenna and laser radiation, the structure of the photon and its “wave” properties, etc.). This preprint analyzes the phenomenon of "redshift" using the concept of the Intervals of space. Based on the data obtained, it is concluded that the hypothesis of a systemic "expansion of the Universe" is not supported. The article's content may be of practical professional interest: - The "redshift" effect can be used to measure distances to distant objects (with a well-developed mathematical basis). - There is reason to believe that "redshift" and "dark energy" are the result of the same mechanism operating in nature. - A previously published preprint presented an analysis of the differences between antenna and laser radiation. As a result, it was shown that these differences provide an opportunity to identify radiations presumably generated by the mind. In antenna radiation, a packet of photons (in the usual sense, a half–wave) with a certain direction of the vector of the electrical component is periodically replaced by a packet of photons with the opposite direction of the vector of the electrical component. There is no such thing in cosmic radiation.

Redshift is a collection of poetry that explores chronic illness through a variety of personal and medical spaces. This includes the manner in which illness intersects with youth, femininity, and sex. Redshift also interrogates the concept of naming an illness as the speaker struggles to get a diagnosis, and by extension, the language and knowledge of her own body.

We introduce an efficient transformation from univariate polynomial commitment based zk-SNARKs to their transparent counterparts. The transformation is achieved with the help of a new IOP primitive which we call a list polynomial commitment. This primitive is applicable for preprocessing zk-SNARKs over both prime and binary fields. We present the primitive itself along with a soundness analysis of the transformation and instantiate it with an existing universal proof system. We also present benchmarks for a proof of concept implementation alongside a comparison with the current non-transparent state-of-the-art. Our results show competitive efficiency both in terms of proof size and generation times. At the 80-bit security level, our benchmarks provide proof generation times of about a minute and proof sizes of around 515 KB for a circuit with one million gates.

The light emitted by celestial objects can have its wavelength "stretched" in different ways before it is observed by astronomers. These stretching phenomena are collectively called "redshift". They influence virtually all aspects of astronomy and even underpin the "Big Bang" theory of the creation of the universe. This book details the types of redshift and explains their myriad of uses. It begins by introducing the nature of light and the problems involved in measuring its properties. After explaining the redshift phenomena and their uses, the book touches on the age and size of the universe; two subjects embroiled in controversy because of our current interpretation of the redshift. Less conventional theories are then expressed. As a by-product of the explanation of redshift, the book offers the reader a basic understanding of Einstein's theory of relativity. Mathematical treatments of the concepts introduced in the text are boxed off and should not detract from the book's readibility, but allow it to be used as a textbook by students of astronomy at all levels. It is also suitable for astronomers and astrophysicists, amateur astronomers, and any science enthusiast.

A series of six ‘camera-less’ photographs made by exposing light through translucent meteorite fragments as if they were photographic negatives. The images are abstract yet offer us a window into a meteorite’s formation at the birth of the solar system some 4.75 billion years ago, long before the formation of the Earth. Whilst the image relates cosmic time to the time and light embedded in any photograph, the title includes a copyright statement outlining an experimental comet-like scattering of the image into the public domain after the artist’s death.
\nThe works were made with the close assistance of two leading lawyers: Joanne Wheeler, Partner, CMS Cameron McKenna, London and Robert Lands, Partner, Finers Stephens Innocent, London.

Received mmddyy / accepted mmddyy We report results from a deep search for redshifted HI 21cm absorption in 55 strong MgIIλ2796 absorbers (having Wλ2796 0> 0.5Å) at intermediate redshifts, 0.58<zabs< 1.70, with the Green Bank Telescope (GBT) and the Giant Metrewave Radio Telescope (GMRT). Nine detections of HI 21cm absorption were obtained, all at 1.17<zabs< 1.68, including three systems reported earlier by Gupta et al. (2007). Absorption was not detected at> 3σ significance in 32 other MgII absorbers, with 26 of these providing strong upper limits to the HI 21cm optical depth,τ3σ < 0.013 per ∼ 10 km s−1. For the latter 26 systems, the spin temperature Ts of the absorber must be> [800 × f] K (where f is the covering factor), if the HI column density is ≥ 2×10 20 cm−2, i.e. if the absorber is a damped Lyman-α system (DLA). Data on the remaining 13 systems of the sample were affected by radio frequency interference and were hence not useful. Two of the MgII absorbers, at zabs ∼ 1.4106 towards 2003−025 and at zabs ∼ 0.9115 towards 2149+212, are known DLAs. We detect HI 21cm absorption towards 2003−025 with
