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).
It will occur because according to the second law of thermodynamics, the amount of entropy in a system must always increase..
Following the increase of entropy, the dissipation of matter and energy goes on until our universe becomes so infinitely disordered that entropy can no longer increase and events come to an end.
This is called the heat death of the universe.
Some say that, because things cannot get any worse, nothing happens at all..
The heat death of the universe (also known as the Big Chill or Big Freeze) is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy..
The heat death paradox, also known as thermodynamic paradox, Clausius' paradox and Kelvin's paradox, is a reductio ad absurdum argument that uses thermodynamics to show the impossibility of an infinitely old universe..
Indeed, the implication is that the universe must ultimately suffer a “heat death” as its entropy progressively increases toward a maximum value and all parts come into thermal equilibrium at a uniform temperature.
After that point, no further changes involving the conversion of heat into useful work would be possible..
His theory of “heat death” stated that the universe is gradually running down and eventually will reach the point of maximum entropy or heat death where all available energy will have been expended and no more activity will occur.
The heat death of the universe corresponds to a state of eternal rest..
This is the timeline of the Universe from Big Bang to Heat Death scenario.
The different eras of the universe are shown.
The heat death will occur in around 1.7\xd710106 years, if protons decay..
Using that survey, we found that the universe is slowly "dying".
Put another way:
If the curvature of the universe is hyperbolic or flat, or if dark energy is a positive cosmological constant, the universe will continue expanding forever, and a heat death is expected to occur, with the universe cooling to approach equilibrium at a very low temperature after a very long time period.
The most important impact of dark energy is that the universe’s expansion will never slow down.
It will only accelerate.
Decades of observations have only confirmed researchers’ findings.
All signs now point to a long and lonely death that peters out toward infinity.
The scientific term for this fate is “heat death.” .
And even they will evaporate away after some 10 100 years.
At this point, the universe will be nearly a vacuum.
Particles that remain, like electrons and light particles (photons), are then very far apart due to the universe's expansion and rarely – if at all – interact.
This is the true death of the universe, d믭 the "heat death".
