  1. How Much, How Hot? by 4of12 · · Score: 4, Insightful

    The linked article is kind of high-level and sketchy on details. Some questions come to mind:

    • How many eV?
    • How much volume did it occupy?
    • How long did it live?
    • How did it decay?
    • What kind of cold matter did it condense into?

    Maybe someone knows a URL for the 3 preprint PDFs going to Phys Rev Lett?

      How does one duplicate THE creation of THE universe (emphasis added)?

      One doesn't. If one were able to, it would almost certainly destroy what's here right now. What one does is duplicate "conditions a fraction of a second after the birth of the universe."

      Which is an entirely different situation. It is merely duplicating in a small bit of matter the state of all matter that existed at the time, a soup of all the stuff that makes particles.

      I'd say you were being too literal, except nowhere before your statement did I see any mention of someone duplicating the creation of the universe. Thus, I'd have to say you're reading a little much into the initial statement.
