Researchers have found that a supposititious form of dark push may contribute to a grim fate for the world : a " long freeze " where everything just … slow down .
In this scenario , the universe would expand to a finite sizing , but everything would mature so cold that all activeness would basically cease .
Dark energyis the mystic force responsible for speed up the expansion of the universe of discourse . It was chance upon in the 1990s , but despite over two decades of research , it still stay the central secret of modern cosmology . Over the years , scientist have presented some fascinating research into what it is and how it works .
One idea is known as holographic moody energy . In this scenario , gravity — andspaceitself — is an illusion . Ouruniverseis really only two - dimensional , and alien quantum forces on that surface give rise to the appearance of somberness and the body structure of 3D space .
A consequence of this possibility is a born accelerated expansion of the universe , which we name as blue energy .

While many research worker have study holographic dark vim modeling and way to test it , a pair of astrophysicist canvas the long - terminal figure destiny of the cosmos if it is indeed ruled by holographic benighted energy . They bring out their outcome Sept. 30 to the preprint databasearXiv . ( It has not been compeer - review . )
Dark push takes up about 70 % of the energy density of the intact cosmos . As the universe elaborate , the density of both unconstipated and glum matter drops , while more and more dark energy manifests . To study the ultimate long - term lot of the population , the researchers disregard issue and pore solely on the evolution of holographic dark energy .
They detect that , as expected , holographic dark energy will continue to expand the universe . But , over time , its influence will slowly peter out and slow acceleration . The universe ’s expansion charge per unit will steadily decrease until the cosmos reaches a intimately still value , essentially locking it to a last size of it .

But as the universe ’s expansion slacken down , the compactness of holographical saturnine energy dwindles along with it . And since the density of matter also contract as the universe expands , the universe grind to a halt . The researchers nickname this scenario " the recollective freeze , " in contrast to other commonly know portion of the universe like the " Big Freeze " ( the accelerated elaboration continues unabated ) and the " Big Crunch " ( something causes the creation to contract back toward theBig Bang ) .
The longsighted freeze is n’t a rosy scenario . While the world ’s expansion will finally block off , there wo n’t be any novel sources of energy for all the subject inside of it . This mean that eventually all the stars will wink out and decay , and all the subatomic particles will drift away from each other in the cold .
unluckily , even in their most alien theories , cosmologists ca n’t come up with a room to give the universe a happy end .
