  physics - Heat death of the universe
The belief of a heat death is derived from the second law of thermodynamics, which claims that entropy tends to increase in an isolated system.
Heat death is however not quite the same as "cold death" or the "Big Freeze " in which the universe simply becomes too cold to sustain life due to continued expansion, though the result is quite similar (see: [1] for a more detailed explanation).
Interestingly, recent work in inflationary cosmology has inverted the heat death notion, suggesting that the early universe was in a thermal equilibrium and thus heat death–like state prior to cosmic expansion.

 Future and Death of the Universe
The first is that the universe will eventually collapse in on itself in the reverse of the Big Bang - a process called the "Big Crunch." This ending would result if there is enough matter in the universe to counteract the force of the expansion.
The universe's geometry is determined by the average density of everything in it - a function of the mass.
Because the universe is a certain age, we can only see that many light-years out; for any part of the universe beyond that, the light has not had enough time to reach us.

 Heat death of the universe - Wikipedia, the free encyclopedia
The heat death is a possible final state of the universe, in which it has "run down" to a state of no free energy to sustain motion or life.
Heat death is however not quite the same as "cold death" or the "Big Freeze" in which the universe simply becomes too cold to sustain life due to continued expansion, though the result is quite similar (see: [1] for a more detailed explanation).
However, in the heat death scenario the energy density is so low that the system can be thought of as non-gravitational, and a state in which the energy is uniformly distributed is a thermal equilibrium state, i.e.

 The Half-Life of Proton Decay and its Relation to the "Heat Death" of the Universe
The metric equivalency between space and time is "gauged" (set, determined, regulated) by the universal electromagnetic constant c; the analogous entropic equivalency between space and time is gauged by the universal gravitational constant, G. G is related to c as entropy is related to energy.
This is because G relates spatial and temporal entropy, hence relating also the "heat death" of the Cosmos to its "information death" via the ultimate decay of the physical carrier (atomic matter) of the Universe's information content.
The notion that the ratio of force strengths relates the "heat death" and the "information death" of the Cosmos via proton decay suggests that if we knew one we would know the other; unfortunately, we know neither, and our force ratio is a pure number, without units.

The 'heat-death' of the universe is when the universe has reached a state of maximum entropy.
The opposite of 'cold death,' as you can see, is NOT 'heat death,' but actually the 'big crunch.' The 'big crunch' occurs when the universe has enough matter density to contract back on itself, eventually shrinking to a point.
The heat death of the universe will only occur if the universe will last for an infinite amount of time (i.e there will be no big crunch).

 Heat Death - SciForums.com
Heat death, as the ultimate ending state for the universe, is just a universal temperature, throughout the universe, right?
Obviously, a species like that couldn't exist at the same time as a "heat death" by your definition of Heat Death because the species is part of the universe.
You are right, nothing could live in total entropy, but because of the expansion of the universe the temperature at the time of the heat death will actually be very very cold.

 Universe - Crystalinks
The universe consists of all matter, light, and other forms of radiation and energy that have been discovered by man. The universe also consists of everything that man believes to be present in space / time as a result of his theories.
In the first half of the 20th century, the name Universe was used to mean the whole spacetime continuum in which we exist, together with all the energy and matter within it.
First structures of the Universe All recent computer-simulations of the early universe have one prediction in common: the first large-scale structures to form in the young universe are long filaments connected at their ends in "nodes".

The phrase Sarah uses, "The sweet breath of the Universe," is oddly reminiscent of the story’s title, The Heat Death of the Universe.
Sarah’s breakdown is precipitated by the death of the turtle.
When the turtle dies, Sarah is forced to accept that the universe will one day die, that, "[a] time must come when the Universe ‘unwinds’ itself, no energy being available for use." She feels that life only makes this time approach faster.

In the very long term the ultimate threat to humanity may be entropy, with the postulated heat death of the universe predicted by the second law of thermodynamics.
The Big Crunch theory postulates that the average density of the Universe is enough to stop its expansion and begin a cosm-wide contraction; a counterpart to the Big Bang.
In the framework of the field equations of the General Theory of Relativity, the simplest model of an accelerating expansion corresponds to a positive value of the cosmological constant, which is often attributed to the quantum vacuum itself exerting a negative pressure that repels gravitationally on large scales.

 Heat Death
Heat Death is the most likely fate of the universe, atoms would be so spread apart, very spread apart
The universe stops expanding and just stays the way it is. If this happens then eventually it will all just get more and more disordered: stars will stop being formed because there's nothing left for fusion and it'll all just be sitting around more or less, decaying into smaller and smaller particles.
Basically right now it's been observed that the universe is expanding with a certain amount of acceleration and in order to reverse this acceleration you would need a sufficient amount of mass in order to slow down and stop the acceleration.

EXPANSION OF THE UNIVERSE: It is assumed that at the beginning of the universe a Big Bang has taken place, setting free a certain amount of matter--energy which would start expanding inflationally because of the initial explosion (alas the "Bang'').
HEAT DEATH OF THE UNIVERSE: As entropy increases, the disorder of matter and energy increases.
As temperature (heat) is a measurement of particle movement, a halt of movement means zero temperature (so it is rather the universe dying of coldness than of heat).

The total entropy of the Universe therefore is increasing, tending towards a maximum, corresponding to complete disorder of the particles in it (assuming that it may be regarded as an isolated system.) See Heat Death of the Universe.
But while the Universe as a whole, if indeed there is a whole Universe, tends to run down, there are local enclaves whose direction seems opposed to that of the Universe at large and in which there is a limited and temporary tendency for organization to increase.
This state is referred to as the "Heat Death of the Universe." Sarah Boyle begins to cry.

 The Second Law of Thermodynamics states that the universe tends toward high entropy. If so, what happens when there is ...
It goes under the name of the 'Heat Death of the Universe.' In short, once all of the energy in the universe is converted to heat then the universe will be in equilibrium -- everything will be of the same temperature and entropy will remain constant forever.
This is the conversion to 'heat.' The reason that we no longer worry about the heat death of the universe is that the time it would take for everything around us to convert to heat is many, many times longer than the current age of the universe.
If we apply the second law of thermodynamics to this then we can see that the universe will continue to spread out and become less ordered and if it survives for long enough will eventually end in the 'Heat Death' when all of the matter has reached equilibrium and the entropy is at its highest.

Pamela Zoline’s suburban society, in “The Heat Death of the Universe,” is characterized by Sarah Boyle, a “typical,” present-day housewife.
Sarah Boyle goes insane because she feels pressure to not contribute to “the heat death of the universe.” Each part of society should maintain order, so the net disorder, entropy, of the universe does not increase to a maximum.
On the contrary, “The Heat Death of the Universe” involves a society that is immensely impacted by entropy and its implications for the end of the universe.

Essentially, the “Law” states that in any closed system (e.g., a sealed room, a sealed bottle, your closet, the universe) the natural tendency is for the elements in the system to degrade from order into chaos.
So, according to the Second Law, the universe as a whole (because it’s assumed to be a closed system) is gradually “running down” as energy is transformed into entropy (order into chaos).
The heat death of the universe is not nigh.
