We’re in the process of
constructing the spacetime model that I say is one of the things the physicists
are missing that’s currently blocking their progress. In this post we’ll learn
more about the structure of our spacetime. To discover its geometry, we used a
symmetry principle—that the physics of the universe should look the same to
every observer. The same principle can teach us something about time. Remember
that there is an aspect of the universe that is atemporal—there’s no time. This
means that the temporal aspect of the universe—the one we see—should also have
zero time. Now, how in the world can a temporal universe have zero time? Easy.
It just has to take a step backward for every step forward in time. What this
does is split our spacetime into two similar fields, one going forward in time
and one going backward. But there’s a subtlety here: one direction always has
more points because the universe expands with every time step, forward or
backward.
Physicists and philosophers are desperately searching for reality, but aren't getting any warmer. An engineer watches the action and offers comments and answers from his work, The Book of the Universe (view my profile and click on My Web Page).

Particles, Dark Matter, and Dark Energy
In my last post, we gave
birth to the spacetime model that the physicists are missing—one of the reasons
why they’re not making progress. Now we need to flesh out the model by adding
the structural details that will allow us to explain the standard models of
particle physics and cosmology.

A Really Big Bang, and then...Inflation
In her excellent blog,
Backreaction, phenomenologist Sabine Hossenfelder laments the difficulty of
finding a precise answer to the question, “What
is a Singularity?” She talks about several kinds of mathematical and
cosmological singularities and attempts to clear up the confusion about them.

Metaphysics Is Physics--Just Think About It.
We tend to think of thoughts as nonphysical, nothing but the
results of electrical activity in our brains. But are they all nonphysical? What
about atemporal existence? As I
explained in this
post, it’s a thought that exists in itself because it’s conscious—it thinks
itself. I say that makes it physical.
as solidly real as any other thing you can think of, and certainly more so than
you or me, since it’s immortal and we’re not. By “physical,” I mean exactly
what you’d think—stuff you can touch and feel.
