Talk:Chronon

message: Is this notable? A Google Scholar search for "chronon" only brings up 648 articles, most of which have under 20 citations.  --Mike Peel 15:22, 30 July 2006 (UTC)
replies: text: Yeah, after reading the article I don't know why I know what a chronon is. It's not referenced in the QM or decoherence articles at all... --HantaVirus 17:06, 31 July 2006 (UTC)
replies: text: In a 1975 article "Skewered" by Isaac Asimov, He calculates the time interval for a particle moving at the speed of light to travel a distance of 1 ferni (10E-13s) as equal to 3x(10E-24s) (which is approximately 10E-23.5s) and calls that 1 chronon and credits the word "chronon" to Stanley G. Weinbaum, A science fiction writer.WFPM (talk) 09:59, 9 August 2009 (UTC)

text: In a 1963 book "View from a height" Asimov wrote an article ("The ultimate split of a second"), where he calls the distance light travels in a second to be a "light fermi".WFPM (talk) 10:14, 9 August 2009 (UTC)
thread_title:  Notability? 

message: "A chronon is a proposed quantum of time, that is a discrete and indivisible "unit" of time, in a theory that proposes that time is not continuous."
Time is not continuous...this doesn't seem rational, even considering quantum mechanics. The other three dimensions (those of space), have no quantized lengths, so why would time? Also, a chronon (2×10-23 s) is like 1021 times longer than a planck time, which is the closest that theories can get us to the Big Bang. If chronons are discrete and indivisble, then what does the planck time denote? I dont think that time is quantized into segments. Instead, a planck time is the smallest interval in the continuous "stream" (FLOABW...) of time that makes physical sense to use (explaination). --HantaVirus 15:35, 14 August 2006 (UTC)
thread_title:  Universal Slideshow? 

message: This is an observation related to the stub "chronon". I believe the possibility that time is quantized is very real. After all, 10 -43 (10 at the 43rd negative potency)is the time that light takes to cross one planck lenght. Bellow that level space and time as we know them do not exist. I have always considered this to be one quantum of time. I am curious, therefore, to know the reasons why the writer of the stub claims the time quantum to measure 10 -22 secs.

thread_title: Equation terms

message: Why is this article rated "high importance"? It is an obscure theory not supported by mainstream physics.  The concept has no visibility to the public at large and the article averages only about 200 hits per day. SpinningSpark 19:47, 3 May 2010 (UTC)
replies: text: Last few months typically about 350 hits a day, or 10,000 hits a month, is quite respectable. You could now maybe justify making this medium importance.--Penbat (talk) 11:57, 22 February 2014 (UTC)
thread_title:  Importance 

message: The concept of chronon has been garnering attention over the last decade. See this October 2013 paper “Upper Time Limit, Its Gradient Curvature, and Matter” by Eytan H. Suchard published in Journal of Modern Physics and Applications 2014, 2014:5   http://scik.org/index.php/jmpa/article/view/1317/640

thread_title:  Chronon field 

message: Suchard's articles are based on Sam Vaknin's dissertation "Time asymmetry Revisited". See Library of Congress record: http://catalog2.loc.gov/vwebv/holdingsInfo?searchId=115001&recPointer=0&recCount=25&searchType=1&bibId=3810279
Suchard's Chronon is a purely geometric approach, complementing Vaknin's asymmetry and spinor-based approach.  — Preceding unsigned comment added by 77.29.140.31 (talk) 16:17, 30 January 2014 (UTC)
thread_title:  Please correct: Vaknin's dissertation, not Suchard's 

message: RFC before changes: the Planck time isn't a quantization of time at all.  It's a minimum time, not an indivisible packet of time.  You can have 13-1/2 Planck times, you just can't have less than 1.
Also, unrelated but might as well mention here: recent evidence suggests the inflationary period began in less than one-billionth of Caldirola's proposed chronon width.  I'm not sure if that discredits Caldirola's width or not, as the article (and sources) are a bit unclear (one could suggest spatial expansion is not quantized in the same way particle motion would be, I suppose).

replies: text: Now the article says: The Planck time [] is not a quantization of time itself [] Additionally, the Planck time is a universal quantization of time itself [] So it isn't, but additionally, it is? --92.208.45.176 (talk) 12:27, 1 November 2016 (UTC)
thread_title:  Misrepresentation of Planck Time 

message: The article says: "While time is a continuous quantity in both standard quantum mechanics and general relativity, many physicists have suggested that a discrete model of time might work, especially when considering the combination of quantum mechanics with general relativity to produce a theory of quantum gravity."
I don´t know how chronon works with the Wheeler–DeWitt equation..?
According to David Deutsch time is a quantum consept. I suppose that chronon , "unit" can be compared to what David Deutsch called "moment" (=world)... Physicist Paul Davies says also that time is not continuous.
BTW, Julian Barbour has also similar ideas, Platonia (philosophy). Kartasto (talk) 10:28, 13 July 2014 (UTC)
thread_title:  Some ideas... 

message: In the article tachyons in fiction, there's a See Also saying:
:A chroniton is a fictional elementary particle with time-travel properties in some works of science fiction.
However, that link to chroniton redirects to this article, which doesn't mention the term, or anything about fictional chronitons. From looking at the history, at one point chroniton and chronon were both stub articles about fictional particles from science fiction. At that point, it probably made sense to merge them. But now that this is an article about the actual physics hypothesis and various related theories, it no longer works.
I believe this article should cover uses of chronon in fiction (especially Star Trek and Doctor Who, but I'm sure there are plenty of other examples), and should also mention that "chroniton" is sometimes used in SF as a synonym for chronon, and sometimes as a distinct technobabble concept (e.g., in at least some Doctor Who novels, chronons are either the quantum of time, or the physical manifestation of the Web of Time, while chronitons are particles given off by time-travel events), as well as a link back to tachyons in fiction. --70.36.140.225 (talk) 04:34, 15 September 2014 (UTC)
