"What If We Have Completely Misunderstood Our Place in the Universe ? A Harvard astronomer has a provocative hunch about what happened after the Big Bang. Our universe is about 13 billion years old, and for roughly 3.5 billion of those years, life has been wriggling all over our planet. But what was going on in the universe before that time ? It's possible that there was a period shortly after the Big Bang when the entire universe was teeming with life. Harvard astronomer Avi Loeb calls this period the 'habitable epoch,' and he believes that its existence changes how humans should understand our place in the cosmos. The full article is here"

    "Essentially, the idea presented in the book is that the lower the energy level, the slower the life gets. All the way from a few instants after big bang (high-energy, high-speed quark-based life, think nanoseconds as hours or so) to trillions of years in the future (quantum-fluctuation [or something like that] based life warming up around evaporating black holes, a single thought takes thousands of years). For each energy epoch, the one before it seemed to be too hot to support life, and the one after it was considered as a heat death of the universe."

    Now THAT is an interesting thought. Wish I could mod up AND post a comment at the same time, but I already commented above. :(

    Humans seem to be stuck on the thought that life must be similar to what we know. Carbon based, in the "Habitable zone", humanoid, etc... When really, we have no idea what it could be, or look like, or even how it interacts with the Universe. What if the intelligent life out there has no sense of sight, but instead uses heat to "see"? i.e. thermal vision. And what if the requirements for this species to live is that they be as far as possible from their star?

    I am sure there have been thousands of books on the subject, but none immediately come to mind, only Star Trek episodes.
