Line 475:

Attempts to find a mathematical basis for this dimensionless constant have continued up to the present time. However, no numerological explanation has ever been accepted by the physics community.

A new theory of unification of interactions, based on trace dynamics and on the exceptional Jordan algebra of the octonions, gives a first principles derivation of the asymptotic value of the fine structure constant, reproducing the measured value exactly. <ref>{{Cite web|last=Singh|first=Tejinder P.|date=23 January 23, 2021|title=(PDF) The characteristic equation of the exceptional Jordan algebra: its eigenvalues, and their possible connection with mass ratios of quarks and leptons|url=https://www.researchgate.net/publication/348355473_The_characteristic_equation_of_the_exceptional_Jordan_algebra_its_eigenvalues_and_their_possible_connection_with_mass_ratios_of_quarks_and_leptons|url-status=live|archive-url=|archive-date=|access-date=2021-01-23|website=ResearchGate|language=en}}</ref>

In the early 21st century, multiple physicists, including [[Stephen Hawking]] in his book ''[[A Brief History of Time]]'', began exploring the idea of a [[multiverse]], and the fine-structure constant was one of several universal constants that suggested the idea of a [[fine-tuned universe]].<ref name=":2">{{cite book |author=Stephen Hawking |year=1988 |title=A Brief History of Time |url=https://archive.org/details/briefhistoryofti00step_1 |url-access=registration |publisher=Bantam Books |isbn=978-0-553-05340-1 |pages=[https://archive.org/details/briefhistoryofti00step_1/page/7 7], 125|author-link=Stephen Hawking }}</ref>
