In materialist philosophical terms, the universe is the summation of all particles that exist and the space in which all events occur which has an equivalent idea amongst some theoretical scientists known as the total universe.
In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist.
We live in the center of the universe that we observe, in apparent contradiction to the Copernican principle which says that the universe is more or less uniform and it has no distinguished center.

 Universe Summary
The case of a flat universe is special, because unless the universe is very close to being flat, its lifetime is calculated to be much shorter than the observed age of the universe.
Because cosmic inflation removes vast parts of the total universe from our observable horizon, most cosmologists accept that it is impossible to observe the whole continuum and may use the expression our universe, referring only to that knowable by human beings in particular.
It has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse.

 Re: A Challenge: The Origins and Evolution of the Universe - Astronomy.com Forums
The steady state theory was developed as a result of theoretical calculations that showed that a static universe was impossible under general relativity and observations by Edwin Hubble that the universe was expanding.
Problems with the steady-state theory began to emerge in the late 1960s, when observations apparently supported the idea that the universe was in fact changing: quasars and radio galaxies were found only at large distances (i.e., redshift, and thus, because of the finiteness of the speed of light, in the past) not in closer galaxies.
At the same time, after the unexpected observation of an accelerating universe in the late-1990s, there were efforts to develop quasi-steady state theories, in which there is not a single big bang but rather multiple big bangs over time which create matter.

The giant star, HE0107-5240, discovered in 2002 by researchers at the University of Hamburg, is believed to be the oldest yet discovered star in the Milky Way, since unlike younger stars, it is virtually metal-free.
When astronomers speculated that certain objects previously classified as spiral nebulae were actually vast congeries of stars, this was called the "island universe theory"; but this was an obvious misnomer, since universe means everything there is. Consequently, this term fell into disuse, replaced by applying the term galaxy generically to all such bodies.
However, the nebulae were not universally accepted as distant separate galaxies until the matter was settled by Edwin Hubble in the early 1920s using a new telescope.

Since the size of the universe is unknown, the total numbers of atoms in the universe is unknown, but the number is not thought to be infinite because current theory suggests we live in a finite universe.
One thing we can say about the mass of the baryons in the universe, meaning the mass of the protons and neutrons, is that we can tell what the ratio of their density ought to be from the Big Bang model.
Therefore, examining one region of the universe and the density of atoms in that region should tell us how densely atoms are scattered throughout the entire universe, but as said previously, does not tell us how far the universe extends and how many atoms exist in total.

 Gnosticism - Deistpedia, the Deist encyclopedia
This view of the universe would later develop into the Stoic indentification of the universe with God; this is not to imply that the Stoic saw the universe as an object of worship, but rather as an object of contemplation.
Like Platonics, Neo-Platonics and Christians, they also held the universe to be only the most immediate level of reality; unlike these groups, they did not view the universe as a cosmos, but rather as a flawed process from which the true, spiritual source of beauty is distant.
Jung understands the emergance of the Demiurge out of the original, unified monadic source of the spiritual universe by gradual stages to be analogous to (and a symbolic depiction of) the emergence of the ego from the unconscious.

 Universe - Wikipedia, the free encyclopedia
In strictly physical terms, the total universe is the sum of all matter that exists and the space in which all events occur or could occur.
The part of the universe that can be seen or otherwise observed to have occurred is called the known universe, observable universe, or visible universe.
The comoving distance to the edge of the visible universe is about 46.5 billion light years in all directions from the earth; thus the visible universe may be thought of as a perfect sphere with the earth at its center and a diameter of about 93 billion light years.

 Dark matter Summary
If there is sufficient mass in the universe the mutual gravitational attraction of all particles will eventually slow the expansion of the universe and the universe will be fated to undergo cyclic contractions and expansions.
At present, the density of ordinary baryons and radiation in the universe is estimated to be equivalent to about one hydrogen atom per cubic meter of space.
This result suggests that either Newtonian gravity does not apply universally or that, conservatively, upwards of 50% of the mass of galaxies was contained in the relatively dark galactic halo.

 The Actual and the Possible
Supposing there are such universes solves the problem of what makes true modal statements true, and Lewis thinks is useful for many other philosophical purposes, such as for saying that a proposition is nothing but the set of worlds at which it is true.
On their accounts, worlds turn out to be abstract Platonic entities, exactly one of which is instantiated by the universe, where “the universe” is defined to be the aggregate of all existing or occurring concrete entities, and this is the world that is absolutely actual.
If things in the universe were otherwise than they are, then different propositions would stand in these relations to things in the universe—if there were unicorns, then the proposition that there are unicorns would stand in the relation of being made true by to some things, namely the unicorns in the universe.

 Entropy - Article from FactBug.org - the fast Wikipedia mirror site
Nevertheless, it has been pointed out that the universe may be considered an isolated system, so that its total disorder should be constantly increasing.
It has been speculated that the universe is fated to a heat death in which all the energy ends up as a homogeneous distribution of thermal energy, so that no more work can be extracted from any source.
Furthermore, complicating factors such as the impact of gravity, energy density of the vacuum (and thus a hypothesized "antigravity"), and macroscopic quantum effects under unusual conditions cannot be reconciled with current thermodynamical models, making any predictions of large-scale thermodynamics extremely difficult.

Using inflation theory, the number of atoms in the observable universe can be estimated to be between 4×10
However, because of the possibly infinite nature of the universe, the total number of atoms in the entire universe may be much larger or even infinite.
This does not change the estimated number of atoms in the observable universe since that is the number of atoms within about 14 billion light years of us - which is all that we can observe since the universe is only about 14 billion years old.
