Introduction to the Block Universe for Everyone
There is an important result from modern physics that everyone
needs to be aware of. It's been "hidden" for a long time for
various reasons but it is now popping up more and more in scientific
and philosophical books and journals. It gives the best ever
proof for the existence of God and a human soul. And changes our
entire understanding of the world we live in. And more besides!
To start, take a look at the following 20 second video:
What did you see? You're probably going to say you saw one palm tree moving in the breeze. But that was a video. What you really saw were 435 images of the tree. Well, that's a video. But if you were looking at the palm tree on the beach (in Carolina, Puerto Rico, just east of San Juan, BTW) would you be seeing a whole series of images? Or would you be seeing just one tree where the parts are moving around in the breeze? The standard assumption we make about the world is that we see parts moving around. But is that assumption right? Maybe when you are right there on the beach (or anywhere in this world) you ARE seeing a whole series of different, unique images. Is there some way to tell if you're seeing things moving around or a series of images just like in a video? It turns out there is a way to decide this.
This issue was settled by a physicist/mathematician, Hermann
Minkowski in 1908 although often people say Einstein gets the credit
because the idea is used in his theories of special relativity and
general relativity. But hardly anyone knows about this result. It
is an idea that has never really leaked out to the general public.
Some physicists who specialize in time and Einstein's theory of
relativity know about it as do philosophers who study the issue of
time. It is only in the last 20 years or so that more people have
been paying attention to this result. The answer is that we ARE
viewing one 3D image after another, after another. The universe is
just like a video that we are watching except it is a 3D video and
each "image" in the video is huge. Each 3D image is a snapshot of
the entire universe at a given moment in time! Now, in a video, as
you start to watch it, everything you're going to see in the future
is already out there for you to see. Then when you are half-way
through the video, the part that you watched is still there.
Physicists found that the universe is really a huge block of
everything that has ever happened, is happening now or will
happen in the future. They call it the block universe,
or sometimes the blockworld. So they say that the past,
present and future are all equally real. There is absolutely
nothing that makes the present special except that it is what we see
right NOW. In philosophy, the idea is called eternalism and
goes way back in time to the Greek philosopher, Parmenides of Elea.
For some documentation on the reality of this result you can go to
my collection of quotes and references on the block universe:
Science Points to the Block Universe.
There are more analogies to help understand the block Universe result.
First of all, consider an amusement park ride such as the haunted
mansion ride at Disneyworld. The whole ride was built in advance.
When you start out at the beginning of the ride, everything you are
going to see in the future is already out there. It has all been
prepared for you. Then when you are halfway through the ride, the
part you have already seen is still there, just like the past of our
real world is still there. The future that you're going to see is
still there ahead of you. And when you finish the whole ride, the
whole past of the ride is still there and it is the same as when you
started your ride.
Then there is the analogy of reading a book. First, the author has
to prepare the entire book in advance and when all the details have
been taken care of, the book is finished and then it is published.
When a reader picks up the book and starts reading chapter 1, the
whole future is out there ahead of the reader. As you move through
the book, going page by page, the page you are reading now is the
present, the pages you have read are in the past and the pages you
haven't read yet are still there in the future.
Then, for the final analogy, there is virtual reality, as in the
film, The Matrix. In virtual reality, a computer feeds
impulses into your brain and picks up what your brain outputs. In
virtual reality, the computer prepares a world that looks as real as
the real world. Now in this situation you need to constantly feed
frame after frame of visual information into the brain. The
difference is that in our real world, you don't just have one 2D
image after another (that appears to be 3D). You have one "3D
image" after another and it will be your consciousness that moves
through the universe of "3D images". And, as far as we can tell, in
our world, those "3D images" really are out there.
The alternative to eternalism is called presentism. If
presentism was true, then when you are on the beach in Puerto Rico
looking at the palm tree, the palm tree is a 3D object with leaves
that move around over time. Presentism includes the idea that there
are particles moving around through space as they are acted on by
forces. This is the 19th century vision of the world.
The creation of a block universe is interesting. It gets created
all at once, as philosopher Barry Dainton says in this quote:
Imagine that I am a God-like being who has decided to design and
then create a logically consistent universe with laws of nature
similar to those that obtain in our universe...Since the universe
will be of the block-variety I will have to create it as a whole:
the beginning, middle and end will come into being together.

So everything that is ever going to happen or is ever going to exist
will show up in this block universe. That's everything across all
of space AND TIME! That's going to be every particle, every star,
every galaxy and every planet that will ever exist for the entire
lifetime of this block universe. There will be a "3D image" for
every moment of time.
With presentism, you can claim that the universe evolves as
particles move around. And of course, many people like to think
that with particles moving around, living cells can form by chance
and then evolve by chance. But our block universe is nothing like that.
In our block universe we've got lots of living things and those living
things are extremely complicated. And they all showed up at once!
People often ask the cute question, "Which came first, the chicken
or the egg?". The answer is that all the chickens and all the eggs
across all of time all showed up all at once. It was not just
chickens, of course, the same applies to every living thing. They
all appeared at once. There just wasn't any time available to
evolve any living things. It was just "poof" and then they
were all there. So now, naturally, evolution by chance (and with
it, atheism) has been killed in a single stroke. There must have
been a Creator to make these intelligent designs. Of course, if
you're trapped in time like we are, but you could observe the
history of the whole Earth by rapidly moving through our dimension
of time, you may or may not find Darwinian-style
evolutionary changes occurring. Whether or not you find
Darwinian-style evolution in the block universe is no longer relevant to
the creation issue. Everything you see appeared at once. That is
where the real act of creation took place.
All of this leaves atheists with a difficult situation. They can be
modern, rational and scientific and accept the results from 20th
century science (rather than 19th century science) and concede that
there is a Creator. Or they can stonewall it and hope that
something will come along to discredit the block universe. This is
extremely unlikely. The science has been around for over 100 years
and every time special relativity and general relativity have been
tested they have worked perfectly. Or they can assume some highly
advanced aliens have come up with a simulation and are feeding that
simulation into our brains that are sitting in vats somewhere.
It was hard for people to accept the idea that the Earth was not
flat. It was hard for people to accept the idea that Earth was not
at the center of the universe and that the Earth went around the sun
instead of the sun went around the Earth. It was hard to accept
that the continents moved. The block universe idea is
the worst of all of them. It will be very hard to get used to,
especially in this day and age. In this day and age people have
accepted the 19th century view of the world that things are
happening at random and that through science, education and
political action it is possible to improve the world by human
efforts alone. This is the politically correct position. Instead,
modern science makes it clear that there is a Creator and the
Creator has a plan for this world and that plan is already out there
in the future.
