Era of DNA decoupling: the onset of life ~

  1. Jan 5, 2004 #1
    The first realistic chance for carbon-based life to form in our universe is demarcated at the cosmic temperature of approximately 100 oC (373K), the maximum temperature withstood by primitive DNA. Since the cosmic temperature today (15 billion years) is 2.7K, and since (radiative t vs T formula from Cosmology by Rowan-Robinson)

    t-1/2/(15 billion years)-1/2=373K/2.7K,

    the era of DNA decoupling is at approximately t=800,000 years, before the formation of the stars, but well enough after hydrogen decoupling. Stardust indeed!
