I had to borrow a promise to persuade you to smile.
Then I pawned my own future just to hold you a while.
I've seen you following the drifters
but you always end up here.
I had to conquer indifference to convince you to give.
Chase the taillights of demons to be near where you live.
While your torn between two worlds
seems you always end up here.
Can't imagine you'd be waiting, even resting in you anger,
while the hypocrites and lovers take their pleasure where they find it.
I've declined the many favors of the well intentioned stranger.
I'd prefer to bare your sadness and whatever's left behind it.
I had to wander in silence to remember your face.
A lifetime of successes couldn't hide your disgrace.
I've seen you circling the heavens
but you always end up here.
We cannot speak of time, we must speak of space/time. Time and space
began together.
If we did not live on the arm of a spiral galaxy but instead lived
near the galactic center you would not be reading this now. The
intensity of the radiation does not allow for life.
Also the early universe was much hotter, and if the universe were not
expanding the radiation would not be dissipated and the night sky
would be 300 times brighter than the day sky is now.
The latest theory being tossed around is that the universe is really a
multiverse (brane theory).
The big bang may have occurred when two undulating membranes
touched at a point. The universe has been expanding ever since. Either
it has enough mass to eventually stop expanding and collapse again (a
closed universe) or it will expand forever (an open universe) as it
turns out the the universe appears to be balanced right between these
and has been said to be flat.
Faster than light
This explanation is of a closed universe. An open universe cannot be
visualised because every point in space is saddle shaped.
Einstein did not know when he penned his famous theories, that space
was stretching.
In fact the universe is stretching or expanding from the three
dimensions we know, into a higher dimension.
We can not visualise this but we can visualise two dimensions
expanding into three.
It would look like the skin of a balloon. The skin of the balloon is
just like a sheet of paper and has been called flatland, a two
dimensional universe. If you put little dots all over it to represent
the galaxies and you blow this balloon up, you will see the dots are
moving away from each other just like the galaxies are doing. No
matter which direction you look, you are looking into the past at a
time when the universe was smaller.
Now lets say this balloon has a north and south pole.
If you are standing at the north pole and you look out across this two
dimensional surface you will notice that the universe has no edge. If
light were infinitely fast and you had a powerful enough telescope you
could see the back of your head.
But light takes time to travel. And so as we look out across space we
don't see the surface of a sphere but a sight line spiraling in toward
the center like the shell of a nautilus.
Let's imagine that the universe is 5 billion light years around and
the light leaving a star at the south pole travels two and a half
billion years to reach us if the universe were not expanding.
But because it is expanding, by the time the light reaches us six and
three eighths billion light years later, the universe is now twenty
billion light years around.
If you graph this out on a sheet of paper, you will notice that space
was stretching out so fast that it exceeded the speed of light.
There is also another scenario in which space swirls faster than light.
The space around a spinning black hole is being spun by the immense
gravity at a rate faster than light.
As it turns out, the rate that the universe is expanding is actually
accelerating. This is not completely understood by physicist at this
time.
Fredkin has proposed a theory that you might find interesting.
Digital physics suggests that there exists, at least in principle, a
program for a universal computer which computes the evolution of the
universe in real time. The computer could be, for example, a huge
cellular automaton (Zuse 1967), or a universal Turing machine, as
suggested by Schmidhuber (1997), who pointed out that there exists a
very short program that can compute all possible computable universes
in an asymptotically optimal way.
Some try to identify single physical particles with simple bits. For
example, if one particle, such as an electron, is switching from one
quantum state to another, it may be the same as if a bit is changed
from one value (0, say) to the other (1). A single bit suffices to
describe a single quantum switch of a given particle. As the universe
appears to be composed of elementary particles whose behavior can be
completely described by the quantum switches they undergo, that
implies that the universe as a whole can be described by bits. Every
state is information, and every change of state is a change in
information (requiring the manipulation of one or more bits). Setting
aside dark matter and dark energy, which are poorly understood at
present, the known universe consists of about 1080 protons and the
same number of electrons. Hence, the universe could be simulated by a
computer capable of storing and manipulating about 1090 bits. If such
a simulation is indeed the case, then hypercomputation would be
impossible.
Loop quantum gravity could lend support to digital physics, in that it
assumes space-time is quantized. Paola Zizzi has formulated a
realization of this concept in what has come to be called
"computational loop quantum gravity", or CLQG. Other theories that
combine aspects of digital physics with loop quantum gravity are those
of Marzuoli and Rasetti and Girelli and Livine.

It is quite an investment in time but a thoroughly
enjoyable read.
