Bill Napier (politician)
William M. Napier (born 29 June 1940 in Perth, Scotland) is the author of five high tech thriller novels and a number of nonfiction science books. Career He received his Bachelor of Science degree in 1963 and his Doctor of Philosophy degree in 1966, both from the University of Glasgow. Napier is a professional astronomer who has worked at the Royal Observatory in Edinburgh, the University of Oxford and Armagh Observatory. He is currently an honorary professor of Astrobiology in the Center for Astrobiology at Cardiff University, which describes him as "a leading figure in the dynamics and physics of comets, and a pioneer of the modern versions of catastrophism." And honorary professor at the Buckingham Centre for Astrobiology, University of Buckingham, which describes him as, "a pioneer of modern studies of the impact hazard due to asteroids and comets," and also as having, "carried out an investigation of long-running claims of anomalous QSO/galaxy associations."

Perth, Scotland
Perth (Scottish English, locally: ; gd, Peairt ) is a city in central Scotland, on the banks of the River Tay. It is the administrative centre of Perth and Kinross council area and the historic county town of Perthshire. It had a population of about 47,430 in 2018. There has been a settlement at Perth since prehistory, prehistoric times. It is a natural mound raised slightly above the flood plain of the Tay, at a place where the river could be crossed on foot at low tide. The area surrounding the modern city is known to have been occupied ever since Mesolithic hunter-gatherers arrived there more than 8,000 years ago. Nearby Neolithic standing stones and circles date from about 4,000 BC, a period that followed the introduction of farming into the area. Close to Perth is Scone Abbey, which formerly housed the Stone of Scone (also known as the Stone of Destiny), on which the King of Scots were traditionally crowned. This enhanced the early importance of the city, and Perth becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coherent Catastrophism
The Shiva hypothesis, also known as coherent catastrophism, is the idea that global natural catastrophes on Earth, such as extinction events, happen at regular intervals because of the periodic motion of the Sun in relation to the Milky Way galaxy. Initial proposal in 1979 William Napier and Victor Clube in their 1979 ''Nature'' article, ”A Theory of Terrestrial Catastrophism”, proposed the idea that gravitational disturbances caused by the Solar System crossing the plane of the Milky Way galaxy are enough to disturb comets in the Oort cloud surrounding the Solar System. This sends comets in towards the inner Solar System, which raises the chance of an impact. According to the hypothesis, this results in the Earth experiencing large impact events about every 30 million years (such as the Cretaceous–Paleogene extinction event). Later work by Rampino Starting in 1984, Michael R. Rampino published followup research on the hypothesis. Certainly Rampino was aware of Napier ...

Catastrophism
In geology, catastrophism theorises that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope. This contrasts with uniformitarianism (sometimes called gradualism), according to which slow incremental changes, such as erosion, brought about all the Earth's geological features. The proponents of uniformitarianism held that the present was "the key to the past", and that all geological processes (such as erosion) throughout the past resembled those that can be observed today. Since the 19th-century disputes between catastrophists and uniformitarians, a more inclusive and integrated view of geologic events has developed, in which the scientific consensus accepts that some catastrophic events occurred in the geologic past, but regards these as explicable as extreme examples of natural processes which can occur. Proponents of catastrophism proposed that each geological epoch ended with violent and sudden natural catastrophes such as m ...

1940 Births
Year 194 ( CXCIV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Septimius and Septimius (or, less frequently, year 947 ''Ab urbe condita''). The denomination 194 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Comet Research Group
The Comet Research Group, Inc. (also known as the CRG) is non-profit organization whose members promote their research focused on cosmic impact events or meteor air bursts on Earth in the distant past, including events of biblical significance. Archeologist Carl Feagans and NASA astronomer David Morrison have described the group's theories as pseudoscientific and pseudoarchaeological catastrophism, particularly where related to Abu Hureyra and the Younger Dryas impact hypothesis. These proposals are typically proposed in opposition to what they view as uniformitarianism. History The CRG was founded by paleoceanographer James P. Kennett and others who contend that the incidence of comet and meteoritic impacts of global significance is much higher than what is normally considered the rate. The multidisciplinary CRG membership roster lists at least sixty scientists from fifty-five colleges and universities (both accredited and unaccredited), as well as several non-scientists ...

Science Daily
''Science Daily'' is an American website launched in 1995 that aggregates press releases and publishes lightly edited press releases (a practice called churnalism) about science, similar to Phys.org and EurekAlert!. The site was founded by married couple Dan and Michele Hogan in 1995; Dan Hogan formerly worked in the public affairs department of Jackson Laboratory writing press releases. The site makes money from selling advertisements. As of 2010, the site said that it had grown "from a two-person operation to a full-fledged news business with worldwide contributors". At the time, it was run out of the Hogans' home, had no reporters, and only reprinted press releases. In 2012, Quantcast Quantcast is an American technology company, founded in 2006, that specializes in AI-driven real-time advertising, audience insights and measurement. It has offices in the United States, Canada, Australia, Singapore, United Kingdom, Ireland, Fran ... ranked it at 614 with 2.6 million U.S. vi ...

Younger Dryas Impact Hypothesis
The Younger Dryas impact hypothesis (YDIH) or Clovis comet hypothesis is a speculative attempt to explain the onset of the Younger Dryas (YD) as an alternative to the long standing and widely accepted cause due to a significant reduction or shutdown of the North Atlantic "Conveyor" in response to a sudden influx of fresh water from Lake Agassiz and deglaciation in North America. The YDIH posits that fragments of a large (more than 4 kilometers in diameter), disintegrating asteroid or comet struck North America, South America, Europe, and western Asia around 12,850 years ago, coinciding with the beginning of the Younger Dryas cooling event. Multiple meteor air bursts and/or impacts are said to have produced the Younger Dryas boundary layer (YDB), depositing peak concentrations of platinum, high-temperature spherules, meltglass, and nanodiamonds, forming an isochronous datum at more than 50 sites across about 50 million km2 of Earth's surface.
