Tired light Tired light is a class of hypothetical redshift mechanisms that was proposed as an alternative explanation for the redshift-distance relationship. These models have been proposed as alternatives to the models that require metric expansion of space of which the Big Bang and the Steady State cosmologies are the most famous examples. The concept was first proposed in 1929 by Fritz Zwicky, who suggested that if photons lost energy over time through collisions with other particles in a regular way, an idea not too different from Breit-Wheeler process, the more distant objects would appear redder than more nearby ones. Zwicky himself acknowledged that any sort of scattering of light would blur the images of distant objects more than what is seen. Additionally, the surface brightness of galaxies evolving with time, time dilation of cosmological sources, and a thermal spectrum of the cosmic microwave background have been observed — these effects should not be present if the cosmological redshift was due to any tired light scattering mechanism. Despite periodic re-examination of the concept, tired light has not been supported by observational tests and has lately been consigned to consideration only in the fringes of astrophysics.

Fritz Zwicky Fritz Zwicky (February 14, 1898 – February 8, 1974) was a Swiss astronomer. He worked most of his life at the California Institute of Technology in the United States of America, where he made many important contributions in theoretical and observational astronomy. In 1933, Zwicky was the first to use the virial theorem to infer the existence of unseen dark matter, describing it as ""dunkle Materie "".

Pierre Prévost Pierre Prévost (] ; 3 March 1751 – 8 April 1839) was a Genevan philosopher and physicist. In 1791 he explained Pictet's experiment by arguing that all bodies radiate heat, no matter how hot or cold they are.

Emile Zuckerkandl Émile Zuckerkandl (July 4, 1922 – November 9, 2013) was an Austrian-born French biologist considered one of the founders of the field of molecular evolution. He is best known for introducing, with Linus Pauling, the concept of the "molecular clock", which enabled the neutral theory of molecular evolution.

Alfred Kleiner Alfred Kleiner (April 24, 1849 – July 3, 1916) was a Swiss physicist and Professor of Experimental Physics at the University of Zurich. He was Albert Einstein's doctoral advisor or "Doktorvater." Initially Einstein's advisor was Heinrich F. Weber. However, they had a major falling out, and Einstein chose to switch to Kleiner.

Cosmobiology Historically, the term 'Kosmobiologie' was used by the German medical astrologer Friedrich Feerhow and Swiss statistician Karl Krafft in a more general sense "to designate that branch of astrology working on scientific foundations and keyed to the natural sciences".

Bruno Huber Bruno Huber (November 29, 1930 – November 3, 1999) was a Swiss astrologer who, with his wife, Louise Huber, founded the Huber School of Astrology in 1962. This school of thought specializes in astrological psychology. A later branch of the school opened in the UK in 1983. He previously worked as an assistant to Roberto Assagioli doing psychosynthesis and was a follower of Assagioli's friend and colleague Alice Bailey.

Johann Euler Johann Albrecht Euler (27 November 1734 – 17 September 1800) was a Swiss-Russian astronomer and mathematician. Also known as "Johann Albert Euler" or "John-Albert Euler", he was the first child born to the great Swiss mathematician Leonhard Euler (1707–1783), who had emigrated [for the first time] to Saint-Petersburg on 17 May 1727. His mother was Katharina Gsell (1707–1773) whose maternal grandmother was the famous scientific illustrator Maria Sibylla Merian (1647–1717) and whose father was the Swiss Baroque painter Georg Gsell (1673–1740) who had emigrated to Russia in 1716. Katharina married Leonhard Euler on 7 January 1734 and Johann Albert would be the eldest of their 13 children (only 5 of whom survived childhood).

Astronomer An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as many other celestial objects — either in observational astronomy, in analyzing the data or in theoretical astronomy. Examples of topics or fields astronomers work on include: planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. There are also related but distinct subjects like physical cosmology which studies the Universe as a whole.

Haro 11 Haro 11 (H11) is a small galaxy at a distance of 300,000,000 ly (redshift z=0.020598). It is situated in the southern constellation of Sculptor. Visually, it appears to be an irregular galaxy, as the ESO image to the right shows. H11 is named after Guillermo Haro, a Mexican astronomer who first included it in a study published in 1956 about blue galaxies. H11 is a starburst galaxy that has 'super star clusters' within it and is one of nine galaxies in the local universe known to emit Lyman Continuum photons (LyC).

Sphinx Observatory The Sphinx Observatory is an astronomical observatory located above the Jungfraujoch in Switzerland. It is named after the "Sphinx", a rocky summit on which it is located. At 3,571 m (11,716 ft) above mean sea level, it is one of the highest observatories in the world. Accessible to the public, it is also the second highest observation deck in Switzerland. The mountain top has been tunneled to fit an elevator which ascends to the observatory from the Jungfraujoch railway station, the highest such train station in Europe.
