  WMAP Cosmology 101: Fate of the Universe
The evolution of the universe is determined by a struggle between the momentum of expansion and the pull (or push!) of gravity.
However, recent observations of distant supernova have suggested that the expansion of the universe is actually accelerating or speeding up, like the red curve, which implies the existence of a form of matter with a strong negative pressure, such as the cosmological constant.
Approximately 3/10 of this is in the form of a low pressure matter, most of which is thought to be “non-baryonic” dark matter, while the remaining 7/10 is thought to be in the form of a negative pressure “dark energy”;, like the cosmological constant.

For example, many scientists believe that the physical universe that we observe today came into existence in accordance with the Big Bang theory, without necessarily implying that the universe was created "out of nothing" in an absolute sense.
The Big Bang theory is currently the most popular scientific creation theory, as it has passed a number of experimental tests, including measurements of the anisotropy of the cosmic background radiation, that could not have been known at the time the theory was first proposed.
The belief that a supreme being actually created the universe out of nothing is considered by some to be at odds with the view that the origin of all things can, in principle, be fully accounted for by reference to natural processes alone.

After Edwin Hubble's discovery of an expanding Universe, suddenly the notion of a start and, possibly, an end, was the subject of scientific investigation.
In an open Universe, General Relativity shows that the Universe can exist indefinitely in the future, but will settle down into a state where life as we know it will cease to exist.
It is unclear what the end result would be: a simple extrapolation would have all the matter and space-time in the Universe collapse into a dimensionless singularity, but at these scales quantum effects, ignored by General Relativity, should be considered.

The Technological Singularity and The Ultimate Fate of the Universe
The ultimate fate of the universe is a merger between humanity, matter, and energy - the saturation of reality with intelligence of human origin.
If the universe is finite, progress has a limit, and the saturated universe is left to revolve through equivalent self-reconfigurations of matter, energy, and intelligence.

Cosmogony is the branch of astrophysics that studiesthe origins and structure of the Universe at large (as opposed to the study of theorigins of particular celestial objects).
Correspondingly, a cosmogony is an account of how the Universe came to be; hence, the creation story in the book of Genesis is one such cosmogony, and there are many others, both scientific and mythological.
This is contrasted with cosmology, which studies the Universe at large, throughout its existence.

Omega, one of the two main parameters that explain the evolution of the whole universe - the other is Hubble's Constant - is the ratio of the observed average density of the universe compared to a critical value.
This expansion of the universe "stretches" the wavelength of that light that is traveling to us from these distant galaxies, thus making their light appear redder.

Washington, DC -- Astrophysicists announced today new predictions of the ultimate fate of the universe obtained by calculating the characteristic or maximum size of very distant radio galaxies.
Knowing this distance is equivalent to knowing the global geometry of the universe, or the ultimate fate of the universe.

Abrahamic religions teach that Creation is the origin of the totality of the universe by the action of God.
Hinduism holds that God is the foundation of all being, and that the universe has a definite origin from God; and yet at the ultimate level, all assertions of a distinction between God and creation are meaningless.
Therefore, according to Upanishadic teaching, it is not false to speak of Hindu Creationism (although it is ultimately meaningless).

Davies explores the end of the universe by setting the stage -- drawing from current thinking about the origins of the universe, in fact one of the options for conjecture, in a closed universe system, would be that the last three minutes would resemble quite closely the first three minutes.

I can only hope that the authorities will be less cavalier when I say that Dougie Donnelly is a giant and venomous reptilian from a distant galaxy in human form and must be mercilessly attacked with water cannon until he dissolves.
If the American is correct it seems entirely possible that our universe is not only shaped like a football but actually is a football, in all probability being kicked about by giants who are themselves living in a football-shaped universe being kicked about by giants who are themselves.
And of course, if our universe is a football it must also hold true that our footballs are universes, each filled with a network of galaxies and solar systems, stars and planets populated by people with hopes, fears and dreams much like our own.

Well, the different shapes are indicative of the ultimate fate of the Universe; the ultimate fate is different for each style of universe.
Depending upon the geometry of the Universe, the number density of galaxies at large redshift (===>large recession velocity ===>large distance) should depend upon the geometry of the Universe.
Depending upon the geometry of the Universe, the paths of parallel lines can cross or diverge, A consequence of this is that if measures the angular sizes of distant galaxies, they do necessarily have to decrease as 1/distance (as they would in a flat universe).

Now that we think that there is dark energy, the simple relation between spatial curvature and the ultimate fate of the universe is completely out the window.
That means that the ultimate expansion or contraction of our meager patch of universe is just a tiny part of the big picture — so we shouldn’t take the fate of our little neighborhood too seriously.
Steinhardt and Turok have suggested that the universe is cyclic, repeating an infinite pattern of expansions and collapses.

The only reason BBN does not convert all of the deuterium in the universe to helium-4 is that the expansion of the universe cooled the universe and cut this conversion short before it could be completed.
The problem was that while the concentration of deuterium in the universe is consistent with the Big Bang model as a whole, it is too high to be consistent with a model that presumes that most of the universe consists of protons and neutrons.
After a decade of effort, the consensus was that these processes are unlikely, and the standard explanation now used for the abundance of deuterium is that the universe does not consist mostly of baryons and that dark matter makes up most of the mass of the universe.

The evolution of the universe is determined by a struggle between the momentum of expansion and the pull of gravity.
If the density of the universe is less than the ``critical density'' which is proportional to the square of the Hubble constant, then the universe will expand forever.
The simplest version of the inflationary theory, an extension of the Big Bang theory, predicts that the density of the universe is very close to the critical density, and that the geometry of the universe is flat, like a sheet of paper.

Albert Einstein introduced the idea of a “cosmological constant,” a long-range repulsive effect in the universe, because he believed the universe to be static and recognized that gravity should make it contract.
When Edwin Hubble discovered that the universe is actually expanding, Einstein renounced the cosmological constant, calling it the biggest blunder of his career.

Renormalization-group running of the cosmological constant and the fate of the universe
Authors: Guberina, B. Horvat, R. Stefancic, H. For a generic quantum field theory we study the role played by the renormalization-group (RG) running of the cosmological constant (CC) in determining the ultimate fate of the universe.
Starting from the present-era values for cosmological parameters we demonstrate how the running can easily provide a negative cosmological constant, thereby changing the fate of the universe, at the same time rendering compatibility with critical string theory.
