Wikenigma - an Encyclopedia of Unknowns Wikenigma - an Encyclopedia of the Unknown


[ newest at the top ]

• October 2023 : Wikenigma is introducing 'hashtags' for some articles. For example #Unknowable for subjects which, by their nature, can definitely never be accurately answered. Or #Unfalsifiable? for questions which may never be able to be resolved by experiment. .

• September 2023 : It's quite a slow process, but every now and again a Wikenigma question gets answered. Such is the case with theAntimatter and Gravity problemplugin-autotooltip__plain plugin-autotooltip_bigAntimatter and gravity


The 'Resolved' category archives questions which have been answered since they were added to the site.

As of Sep. 2023, this entry is now moved to the 'Resolved' section.

A recent set of experiments at CERN, which created thousands o…

• September 2023 : Many thanks again to The British Library, which is now archiving the entire Wikenigma site several times a year (latest update July 2023 )..

• Aug. 2023 : In the light of recent developments and proliferation of online AI systems, this is to re-affirm that all of the content of Wikenigma is entirely human edited. It's perhaps inevitable that some AI generated content will eventually be featured - as even some 'peer-reviewed' scientific papers are now appearing with auto-generated content. The current editorial policy is to remove any content known to be AI generated.

• June 2023 : A milestone of 1,000 articles has been reached. Many thanks to all supporters and contributors.

• May 2023 : To complement the upcoming 1,000th article post, Wikenigma has a new logo. The achromatic interrogative cuboid (a black-box with question marks).

• March 2023 : Wikenigma has started a Twitter feed for curator's pick of the moment.

• Feb 2023 : Gearing up for the British Library's yearly site archiving.

• Aug 2022 : A milestone of 900 unknown articles has been reached.

• July 2022 The site was offline for a few days at the end of the month due to overstretched demand. Many apologies.

• Apr 2022 : Moved to new server. Faster page response times.

• Feb 2022 : To support , Wikenigma is introducing a new strategy to mark external links to 'Open Access' reference papers as such. The green icon open access denotes that the entire reference is fully open for all readers, free of any charges.

• Oct 2021 : A milestone of 800 unknown articles has been reached.

• Sept. 2021 : Currently beta-testing an 'auto-translation' engine.

As always with auto-translation, it's a very long way from being perfect . . . but could be of help in attractiing a wider global audience . . .

• July 2021 : A milestone of 700 unknown articles has been reached.

• May 2021 : A milestone of 650 unknown articles has been reached.

• Mar. 2021 : Many thanks to the The British Library, which has now begun permanently archiving the contents of Wikenigma.

• Jan. 2021 : A milestone of 600 unknown articles has been reached.

• Oct. 2020 : A milestone of 500 unknown articles has been reached.

• Aug. 2020 : Currently (beta) testing the new 'WYSIWYG' (What You See Is What You Get) page editor. It greatly simplifies the editing process, avoiding the need to learn the Wiki syntax. (Note: it's currently not 100% stable)

• Aug 2020 : A milestone of 400 unknown articles has been reached.

• Aug 2020 : There are credible rumours of a 'WYSIWYG' (What You See Is What You Get) editing system to help make it easier to create and edit pages without having to use the (quite eccentric) 'Wiki' syntax code. The plugin isn't quite stable enough for general use yet. But when it is, it should make editing pages much more straightforward.

• July 2020 : the core software has been updated - hopefully faster and more stable.

• Apr 2019, there are now around 260 articles.

+ Many thanks to 'No Such Thing as a Fish' and 'QI' who recently tweeted about the site ! The response was so strong the site had to get a server upgrade !

• As of June 2017, there are now around 220 articles detailing real-world, fully documented observations and phenomena which no-one, anywhere, has yet been able to explain. Thanks to our contributors and supporters.

• As of April 2017, there are now around 170 articles detailing items which are as yet unknown to humanity. Thanks to our contributors and supporters.

• March 2017 . . . now out of beta.

• 6th Sep 2016. Moved server to - and now in beta version.

• Alpha launch nearing

Automatic Translation
