Kastner’s is one of two “most important” books in physics and cosmology that I’ve read (and in my opinion of course) over the past 7+ years, the other being “Singular Universe” by R. Unger and L. Smolin. How many books have I read addressing the subject of “quantum mysteries”? Paradoxes of the “double slit experiment”, “action at a distance”, “the impact of the observer”, and so on. Except for hidden variables, mostly rejected for good reasons these days, all of the *explanations* are either mere speculative descriptions of phenomena taking place independently of their observation, or they explain them away. Dr. Kastner (building on the work of her mentor John Cramer) does actually explain these phenomena without hidden variables! Whether you like her hypothesis or not, it has to be a contender.

“Unseen Reality” is Kastner’s very good explanation for a popular audience familiar with the basic issues of…

In this post, I’m going to disagree with the following statement by physicist Sean Carroll concerning the nature of time:

“The weird thing about the arrow of time is that it’s not to be found in the underlying laws of physics. It’s not there. So it’s a feature of the universe we see, but not a feature of the laws of the individual particles. So the arrow of time is built on top of whatever local laws of physics apply.”–Sean Carroll, https://www.wired.com/2010/02/what-is-time/

That is a common position, but it could very well be wrong. Specifically, what could be wrong with it is the claim that the arrow of time is “not to be found in the underlying laws of physics.” That claim comes from ignoring the possibility that there could be real, dynamical, irreversible collapse in quantum theory. If there is such collapse, that provides the missing link between physical…
