Draft:Cosmohedra

Submission declined on 21 September 2026 by Ldm1954 (talk).

This draft's references do not show that the neologism meets Wikipedia's criteria for inclusion. The draft requires multiple published secondary sources that:

provide significant coverage: discuss the term in detail, not just brief mentions or routine use;
are reliable: from reputable outlets with editorial oversight;
are independent: not connected to the subject, such as promoted or sponsored content.

Please add references that meet all three of these criteria. If none exist, the subject is not yet suitable for Wikipedia.

Wikipedia is not a dictionary and we do not accept articles that are simply definitions of neologisms.

If you would like to continue working on the submission, click on the "Edit" tab at the top of the window.
If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.
If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.
Please do not remove reviewer comments or this notice until the submission is accepted.

Where to get help

If you need help editing or submitting your draft, please ask us a question at the AfC Help Desk or get live help from experienced editors. These venues are only for help with editing and the submission process, not to get reviews.
If you need feedback on your draft, or if the review is taking a lot of time, you can try asking for help on the talk page of a relevant WikiProject. Some WikiProjects are more active than others so a speedy reply is not guaranteed.

Comment: The work so far only has a few citations. As such it is WP:TOOSOON you need to wait until it has many hundreds of citations. Not everything belongs on Wikipedia. Ldm1954 (talk) 19:41, 21 September 2026 (UTC)

Cosmohedra are a proposed type of geometric object in mathematical physics. They were introduced in a paper first posted in 2024 and published in Journal of High Energy Physics in 2025, by Nima Arkani-Hamed, Carolina Figueiredo and Francisco Vazão.^[1] The authors proposed cosmohedra as geometric structures for calculating the wave function of the universe, with the aim of replacing large collections of Feynman diagram calculations with a single geometric description. The idea is related to other geometric approaches to quantum field theory and particle physics, including the amplituhedron and associahedra.^[1]

Research

Later research extended the construction to graph cosmohedra.^[2] Forcey, Glew and Kim proposed related “acyclonesto-cosmohedra” as generalisations of the construction in a peer-reviewed article in Journal of Physics A: Mathematical and Theoretical.^[3] Another paper introduced the correlatron, a related polytope whose geometry includes cosmohedron and associahedron facets.^[4]

Cosmohedra have been discussed in independent popular-science coverage. New Scientist described the cosmohedron as a geometric object proposed for reconstructing the quantum wave function of the universe.^[5] Quanta Magazine has discussed the broader research programme involving geometric descriptions of quantum field theory and its relationship to the amplituhedron.^[6]

Cosmohedra remain a subject of ongoing research.
