Stephen Hawking's theory, this is how the universe will end

The theories on the final future of the universe are many and varied: from infinite expansion to the Big Crunch, from singularity to stillness. 

Fortunately, most of these theories place the final event far in the future. 

Today, a new study is added to the list based on the theory of black hole evaporation formulated by Stephen Hawking, the British cosmologist, physicist, astrophysicist, mathematician and populariser of science, one of the world's most influential and well-known theoretical physicists, who passed away in 2018.

Different hypotheses about the ultimate fate of the universe
The universe is the subject of many hypotheses about its ultimate fate, ranging from its infinite expansion to the possible collapse of the Big Crunch, from the formation of singularities to static. Fortunately, these theories place such an event far back in time. However, a new study adds to the list of hypotheses, based on Stephen Hawking's theory of black hole evaporation.

The gradual evaporation of the universe
Astrophysicists at Radboud University in the Netherlands, including Michael Wondrak, Walter van Sujlekom and Heino Falcke, have developed a model according to which the universe is gradually evaporating before our eyes. According to this theory, the universe will cease to exist when the evaporation process is complete. This study was published in the journal 'Physical Review Letters' and is available on the ArXiv server.

The Influence of black hole evaporation theory.
Stephen Hawking's theory of black hole evaporation has had a significant impact on the field of astrophysics. Scientists have applied this theory to the entire universe, suggesting that there may be unknown radiation in addition to the well-known Hawking radiation.

Quantum fluctuations and evaporation of space-time
Scholars were inspired by the Schwinger effect and the theory of black hole evaporation to hypothesise that particles could also spontaneously 'evaporate' from space-time under certain gravitational conditions. The curvature of space-time, caused by the presence of masses, could generate this radiation linked to the tidal forces of the gravitational field.

A distant and uncertain future
The theory of the evaporation of the universe raises questions about its long-term fate. Objects such as the remains of dead stars could also emit radiation similar to that of black holes. However, the time scale for the evaporation of a black hole with the mass of the Sun is extremely long, indicating that the entire universe could take an immense amount of time to completely evaporate. Despite this new discovery, there are still many uncertainties regarding the future of the universe that invite us to continue research and scientific exploration.
