The Arrow of Time from an Overlooked Physical Law

I’m reblogging this as a counterpoint to a recent book by John Gribbin, “The Time Illusion,” claiming that the ‘block world’ picture of spacetime is settled science. In fact, it is not. There is no real physical evidence for the ‘block world’ model, and there are counterexamples to the claim that relativity requires such a model. The inability of the block world to provide a complete explanation for the 2nd Law of Thermodynamics is another reason to keep an open mind regarding alternative, ‘growing universe’ models.

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…
