Here I am trying to describe a model of reality and existence, that does not leave room for questions like, what came before, what caused it, what is its purpose etc. So here goes nothing...
We start with the axiom that we are conscious beings and we exist, and the
known and unknown laws of nature have lead to our existence. We also know that our
world is made up of particles. Each of these particles have a location that is
described by three spatial dimensions and one time dimension,
We can imagine the set of all functions that takes four arguments and return a boolean value to describe such a four dimensional reality, by interpreting the four arguments as the four dimensions and the boolean value to be indicating the presence of a particle at that location in the reality defined by the function.
So in general, we can think of a function that takes
n arguments and return a
boolean value to be describing an
n dimensional reality. For the time being
let us limit our consideration to the set of such functions where
Imagine that we have a computer that can take one of these function and can
render the world described by it on a monitor, by progressing the value of
For most functions in this set, we see nothing interesting.
But for some, we see that the particles in the rendered world behave similarly to the particles in our real world. Some particles appear to attract each other, while others appear to repel each other, like the charged particles behave in our reality. Also in this world we see that most of the particles attract each other, just like force of gravity causes them to attract in the real world.
Thus we can imagine a subset of
Rl that contain functions that describe
realities that implements all the known and unknown laws of our real world. Let
r0 be an element of
When we look at
r0 being rendered on the computer monitor, we see stars and
planets forming in them, and eventually, conscious life forming in one of the
Conscious beings in this rendered world will observe an apple falling down, and
will conclude that it fell down because the planet pulled it down. But we who
are looking the this rendered world know that it fell down because that is just
how the function happen to describe the apple in that slice of time. The planet
didn't pull the apple any more than the
y axis of a graph pulls a parabola to
Thus the inhabitants of this world will have the illusion of causality.
But we know that by the way the world is described by the function, no event
that happen in it can influence, or cause any other event in it. In other
words, all events that happen in it are independent, and is solely described by
As we saw earlier, in the world described by
r0, we see conscious beings.
Let us for a moment, imagine that their consciousness is the result of the
particular configuration of the particles in their brain.
We know that this configuration is not the result of anything that happen out
there in that reality, and it is solely described by the function
means that if you limit the rendering of this reality, to just the particles in
their brains, the beings in it will still have the sensation of a full reality.
But we know that consciousness cannot be caused by the particles in their
brains. So what if we stopped rendering the particles of their brains as well?
Since we know that the consciousness could not be caused by the configuration
of particles in their brains, the mere existence of
r0 must be
Thus we can see that
r0 just by being defined, can lead to the experience of
conscious beings with the sensation and memory of an entire universe.
In this model, we can see that nothing exist outside of the consciousness. In fact, the consciousness does not perceive objects in it, but the perception is built-in. Existence cannot be absolute, and can only be defined within the confines of realities that harbour consciousness.
And of course, there is no God in this model, unless you want to call the
r0 that defines our reality to be the God.
Time travel could be considered as possible or impossible, depending on how you
want to look at it. If some being in an
r0 defined reality can figure out
r0 itself, then they look into arbitrarily points in space and time.
An interesting thought experiment is to consider the possibility of a being in
r0 defined reality, figuring out
r0 itself. Then it is possible for it to
look into future and possibly alter it. This might seem to be a hole in this
model, but actually, it can be resolved if we consider true
r0 for a reality
cannot be figured by looking at the past only, and require information of the
future as well. And any function
r0' that a being in the reality thinks is
r0, (because it can accurately look into past), could be one that shares
only the past, but not the future, and could actually show them a future which
causes them some action which result in a future that is described by true
So basically, the beings inside the reality will perceive it to be true time travel and have the illusion of having altered the future.
The chances of some molecules coming together to form the fundamental building
blocks of life is often considered too slim to happen within the known spatial
and temporal dimensions of our universe. But in this model, we are only limited
by the possible realities that are implemented by
r0 like functions, which
are truly infinite.
If the realities allow randomness to co-exist with conciousness, then it is possible that multiple realities can exist, with exactly same laws of nature, but with different histories.
For this we just need to introduce a fifth argument to the
r0, and this
argument will govern the "random" behavior that beings inside the reality
observe. Since this argument can have an infinite number of values, there can
be infinite realities with infinite histories.
