"...of about 14 lunations" [on the age of the universe]


".......Meni, or Manai, signifies "The Numberer." And it is by the changes of the moon that the months are numbered: Psalm civ. 19, "He appointed the moon for seasons: the sun knoweth the time of its going down." The name of the "Man of the Moon," or the god who presided over that luminary among the Saxons, was Mane, as given in the "Edda," and Mani, in the "Voluspa."....."

[from The Two Babylons by Free Church of Scotland minister Alexander Hislop ]

"....The full moon cycle is a cycle of about 14 lunations ..."
[from Wikisource:  ]

"...The best measurement of the age of the universe is 13.798±0.037 billion years

"...NASA's Wilkinson Microwave Anisotropy Probe (WMAP) project's nine-year data release in 2012 estimated the age of the universe to be 13.772±0.059×109 years 

"... In 2013, the European Space Agency's Planck spacecraft team estimated the age of the universe to be 13.82 billion years,

"...The first reasonably accurate measurement of the rate of expansion of the universe, a numerical value now known as the Hubble constant, was made in 1958 by astronomer Allan Sandage 

"...Sandage and other astronomers repeated these measurements...(...)..and thus increase the resulting age for the universe....(....)....using these new models for stellar evolution, the estimated age of the oldest known star is 14.46±0.8 billion years.

    And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. [Genesis 6:5, kjv]


    Interstellar (film)
    From Wikipedia, the free encyclopedia
    Interstellar is a 2014 science fiction adventure film directed by Christopher Nolan. Starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, and Michael Caine, the film features a team of space travelers who travel through a wormhole in search of a new habitable planet. It was written by Jonathan Nolan and Christopher Nolan; Christopher combined his idea with a script developed by his brother in 2007 for Paramount Pictures and producer Lynda Obst. He is producing the film with Obst and his wife, Emma Thomas. Theoretical physicist Kip Thorne, whose works inspired the film, acted as both an executive producer and a scientific consultant for the film.
    Scientific accuracy
    Theoretical physicist Kip Thorne was a scientific consultant for the film, to ensure the depictions of wormholes and relativity were as accurate as possible. "For the depictions of the wormholes and the black hole," he said, "we discussed how to go about it, and then I worked out the equations that would enable tracing of light rays as they traveled through a wormhole or around a black hole—so what you see is based on Einstein's general relativity equations."[52]

    In creating the wormhole and a rotating black hole, which opposed to a non-rotating black hole has an ergosphere, Dr. Thorne collaborated with visual effect supervisor Paul Franklin and a team of 30 computer effects artists at Double Negative. Thorne would provide pages of deeply sourced theoretical equations to the artists, who then wrote new CGI rendering software based on these equations to create accurate computer simulations of the gravitational lensing caused by these phenomena. Some individual frames took up to 100 hours to render, and ultimately resulted in 800 terabytes of data. The resulting visual effect provided Dr. Thorne with new insight into the effects of gravitational lensing and accretion disks surrounding black holes, and will lead to the creation of two scientific papers; one for the astrophysics community and one for the computer graphics community.[53]

    Christopher Nolan was initially concerned that a scientifically accurate depiction of a black hole would not be visually comprehensible to an audience and would require the effects team to unrealistically alter its appearance. However Nolan found the finished effect to be understandable provided that he maintained consistent camera perspectives, "What we found was as long as we didn’t change the point of view too much, the camera position, we could get something very understandable".[54]
