• TITLE: The Hubble Frequency and the Hawking Temperature

  AUTHORS: Espen Gaarder Haug, Eugene Terry Tatum

  KEYWORDS: CMB Temperature, Hawking Temperature, Hubble Frequency, Geometric Mean

  JOURNAL NAME: Journal of Applied Mathematics and Physics, Vol.13 No.12, December 24, 2025

  ABSTRACT: We suggest that there should be a minimum electromagnetic radiation frequency in the Hubble sphere and that this seems to be directly linked to the Hawking Temperature and our recent discovery that the CMB temperature could simply be a geometric mean temperature between minimum and maximum Hawking temperatures in the Hubble sphere; see [1]-[3].
