I'm a biologist, so my physics knowledge is limited to undergraduate physics, Hawking's book, and discovery channel. I'm hoping for some enlightenment regarding a theory that was published in Nature a few years ago where it was postulated that time could be regarded as quanta. I don't really understand even the basics and I can't find the ref., but I believe the author was Peter Shsu (or something like that). Also, I would like to hear some background and opinion on an alternative to the Big Bang theory called the plasma theory in which the universe is not expanding and there was no big bang origin. Thanks in advance.
