Observable universe


In Big Bang cosmology, the observable universe
consists of the galaxies and other matter that we
can in principle observe from Earth in the present
day, because light (or other signals) from those
objects has had time to reach us since the begin-
ning of the cosmological expansion.


The age of the universe is about 13.7 billion years,
but due to the expansion of space we are now
observing objects that are now considerably far-
ther away than a static 13.7 billion light-years dis-


The visible universe is ... a sphere with a diameter
of about ... 93 billion light-years.


Estimates of the matter content of the observable
universe indicate that it contains on the order of
10 to the 80th atoms. The vast majority of the
energy density is contributed by dark matter and
dark energy.


The observable universe contains about 3 to 7
1022 stars (30 to 70 sextillion stars), organized in
more than 80 billion galaxies, which themselves
form clusters and superclusters.

     "the Hubble telescope is capable of detect-
     ing about 80 billion galaxies. In fact, there
     must be many more than this, even within
     the observable Universe, since the most
     common kind of galaxy in our own neigh-
     borhood is the faint dwarfs which are diffi-
     cult enough to see nearby, much less at
     large cosmological distances."

WMAP Content of the Universe

The universe is defined as everything
that physically exists: the entirety
of space and time, all forms of matter,
energy and momentum, and the physical
laws and constants that govern them.

However, the term universe may be used
in slightly different contextual senses,
denoting such concepts as the cosmos,
the world or Nature.

Current interpretations of astronomical
observations indicate that the age of
the universe is

(13.73 + or - 0.12) billion years,

and that the diameter of the observable
universe is at least 93 billion light

According to the prevailing scientific
model of the universe, known as the Big
Bang, the universe expanded from a gravi-
tational singularity, a point in space-
time at which all the matter and energy
of the observable universe was concen-
trated. Since the singularity, the uni-
verse has been expanding to its present
form, possibly with a "brief period" of
cosmic inflation.

Several independent experimental measure-
ments support this theoretical expansion
and, more generally, the Big Bang theory.

Recent observations indicate that this
expansion is accelerating because of the
low density of the universe, and that
most of the matter and energy in the uni-
verse is fundamentally different from that
observed on Earth and not directly observ-


Experiments and observations suggest that
the universe has been governed by the same
physical laws and constants throughout its
extent and history. The dominant force at
cosmological distances is gravity, and
general relativity is currently the most
accurate theory of gravitation.

The remaining three fundamental forces and
all the known particles on which they act
are described by the Standard Model.

The universe has at least three dimensions of
space and one of time, although extremely
small additional dimensions cannot be ruled
out experimentally. Spacetime appears to be
smooth and simply connected, and space has
very small mean curvature, so that Euclidean
geometry is accurate on the average through-
out the universe.

Conversely, on a quantum scale spacetime
is highly turbulent.

The word universe is usually defined as en-
compassing everything. However, using an
alternate definition, some have speculated
that this "universe" is just one of many dis-
connected "universes", which are collectively
denoted as the multiverse.

For example, in bubble universe theory, there
are an infinite variety of "universes", each with
different physical constants. Similarly, in the
many-worlds hypothesis, new "universes" are
spawned with every quantum measurement.
These universes are usually thought to be com-
pletely disconnected from our own and there-
fore impossible to detect experimentally.

Update -- Science's Breakthrough of the Year:
Illumination Of The Dark, Expanding Universe


ScienceDaily (Dec. 19, 2003) - In 2003, new
evidence cemented the bizarre idea that the
universe is made mostly of mysterious "dark
matter," being stretched apart by an unknown
force called "dark energy." This set of dis-
coveries claims top honors as the Breakthrough
of the Year ...

This year, information from the Wilkinson
Microwave Anisotropy Probe (WMAP) satellite
and the Sloan Digital Sky Survey (SDSS) tele-
scopes confirmed some of cosmologists' strang-
est proposals about the fate of the universe.

"The implications of these discoveries about
the universe are truly stunning. Cosmologists
have been trying for years to confirm the
hypothesis of a dark universe. Science is
glad to recognize their success in this effort
as the Breakthrough of the Year for 2003,"
said Don Kennedy, Editor-in-Chief of Science.

Those proposals entered the spotlight five
years earlier, when Science's 1998 Break-
through of the Year honored the discovery
that the universe was expanding. Such an
expansion would likely be driven by a "dark
energy" that counters the effects of gravity.
At the time, however, many cosmologists were
wary of this strange idea.

Their doubts were dispelled in 2003. WMAP
took the most detailed picture ever of the
cosmic microwave background -- the light
emitted by the universe during the first
instant of its existence. By analyzing pat-
terns in this light, researchers concluded
that the universe is only 4 percent ordinary
matter. Twenty-three percent is dark matter,
which astrophysicists believe is made up of
a currently unknown particle. The remainder,
73 percent, is dark energy.

WMAP also nailed down other basic properties
of the universe, including its age (13.7
billion years old), expansion rate and den-



WMAP Content of the Universe


WMAP data reveals that its contents include
4.6% atoms, the building blocks of stars and
planets. Dark matter comprises 23% of the
universe. This matter, different from atoms,
does not emit or absorb light. It has only been
detected indirectly by its gravity. 72% of the
universe, is composed of "dark energy", that
acts as a sort of an anti-gravity. This energy,
distinct from dark matter, is responsible for
the present-day acceleration of the universal

WMAP data is accurate to two digits, so the
total of these numbers is not 100%. This re-
flects the current limits of WMAP's ability
to define Dark Matter and Dark Energy.

The multiverse (or meta-universe (metaverse))
is the hypothetical set of multiple possible uni-
verses (including our universe) that together
comprise all of reality. The different universes
within the multiverse are sometimes called
parallel universes. The structure of the multi-
verse, the nature of each universe within it and
the relationship between the various constituent
universes, depend on the specific multiverse
hypothesis considered.

Parallel Universes

Not just a staple of science fiction, other universes
are a direct implication of cosmological observations

by Max Tegmark 



Level I: Beyond Our Cosmic Horizon



THE SIMPLEST TYPE of parallel universe is
simply a region of space that is too far away for
us to have seen yet. The farthest that we can
observe is currently about 4 1026 meters, or
42 billion lightyears—the distance that light has
been able to travel since the big bang began.

(The distance is greater than 14 billion light-
years because cosmic expansion has lengthened

Each of the Level I parallel universes is basically
the same as ours. All the differences stem from
variations in the initial arrangement of matter. 


Level II: Other Postinflation Bubbles



of parallel universe emerges from the theory of
cosmological inflation. The idea is that our Level I
multiverse—namely, our universe and contiguous
regions of space—is a bubble embedded in an
even vaster but mostly empty volume.

Other bubbles exist out there, disconnected from
ours. They nucleate like raindrops in a cloud.
During nucleation, variations in quantum fields
endow each bubble with properties that distin-
guish it from other bubbles.


Level III: Quantum Many Worlds



number of parallel universes by broadening the
concept of “elsewhere.” These universes are
located elsewhere, not in ordinary space but in
an abstract realm of all possible states.

Every conceivable way that the world could be
(within the scope of quantum mechanics) corre-
sponds to a different universe. The parallel  uni-
verses make their presence felt in laboratory ex-
periments, such as wave interference and quan-
tum computation.


Level IV: Other Mathematical Structures



THE ULTIMATE TYPE of parallel universe
opens up the full realm of possibility. Universes
can differ not just in location, cosmological
properties or quantum state but also in the
laws of physics.

Existing outside of space and time, they are
almost impossible to visualize; the best one
can do is to think of them abstractly, as static
sculptures that represent the mathematical
structure of the physical laws that govern them.

For example, consider a simple universe: Earth,
moon and sun, obeying Newton’s laws. To an
objective observer, this universe looks like a
circular ring (Earth’s orbit smeared out in time)
wrapped in a braid (the moon’s orbit around
Earth). Other shapes embody other laws of
physics ... This paradigm solves various prob-
lems concerning the foundations of physics.


A common feature of all four multiverse levels
is that the simplest and arguably most elegant
theory involves parallel universes by default.


Perhaps we will gradually get used to the weird
ways of our cosmos and find its strangeness to
be part of its charm.
