I just read the following article about a book by Richard Muller. http://www.npr.org/sections/13.7/2016/09/27/495608371/now-and-the-physics-of-time What do you all think of it? Is this really a new idea? "I think that only now can we finally understand the concept of now. In cosmology, we think of the expanding universe as the continuous creation of new space; the universe continues to grow as the space between galaxies increases. That recognition makes it plausible that in the ongoing expansion, the universe is creating not only new space but also new time. Each newly created moment is what we refer to as now. Let's call this the "Now Hypothesis.""
