In chapter 7 of Case Against Reality, Hoffman’s “spacetime is doomed” mantra starts sounding like a hypnotist's spell, as reality fades from view. Here we read more fascinating stories that reveal slivers of actual physics, but then contain too many important omissions to be of any constructive help.
One way Hoffman misrepresents facts and twists conclusions is by anthropomorphizing the results and implications of quantum experiments and theory, all the while ignoring the profound difference between quantum scale experiments, and our macroscopic physical reality.
Or, for that matter, you’ll not hear Hoffman acknowledge the profound difference between his mathematical models of idealized universes and our actual ever evolving universal physical reality.
Of course bias comes into it.
As a simple hands on working man, trying to follow through on Hoffman’s trains of logic leaves me overwhelmed time after time. I don’t kid myself, with my middling layperson understanding of physics, I’m in no position to offer lectures or corrections to Hoffman’s details, nor is that my intent.
Heck, I’ve had to do a lot of searching and additional reading these past weeks and again wrestling with this chapter, trying to grasp the various philosophical strands running through it and trying to wrap my head around the heady pipe dreams of these creative theorists.
My intention is to get through Hoffman’s book then to offer a saner down to Earth alternative. An evolutionary perspective of our Earth and our human relationship with this physical reality we are embedded within. Sans the religious baggage Hoffman’s theorem carries, stay tuned for more on that.
I compensate for my mediocre mind by doing homework and knowing how to check out claims and weigh evidence. For this chapter I’ve blown my deadline and spend a good deal of time learning more about what knowledgeable authorities have to explain. I’ll be sharing highlights throughout this review.
A review of Donald Hoffman’s, Case Against Reality,
chapter 7, Virtuality - Inflating a Holoworld
DH: “… But here, where I don’t expect it, science injects a profound mystery: we still don’t understand “now” and “there”. That is, we don’t understand time and space - length, width, and depth - which we take for granted, which are woven into the very fabric of our daily perceptions, and which we assume are a true and reliable guide to physical reality.” (¶2)

Our spacetime is not doomed, no matter what impression breathless writers fill books and magazines with, no matter how smart the scientist’s mind, or how grandiose and self-certain their pronouncements are.
