The universe can end before what scientists expected
A new study suggests that the end of the universe could happen long before what was thought. But do not worry, that definitive cosmic conclusion would still be in the future unimaginable distant

As the story of our cosmos progresses, the stars will be burned slowly, the planets will freeze and the black holes will devour the light. Pottally, in time of time, so long, humanity will never witness them, the universe will fade into the dark.
But if you have ever wondered exactly when everything could end, you may find it strangely comfortable, or perhaps a bit disturbing, knowing that someone has really made the calculations. It turns out that this cosmic final could come to Soner of what scientists thought previously.
Do not worry, thought: “Before” it still means 10 amounts to the power of 78 years within now. It is a 1 followed by 78 zeros, which is unimaginably far in the future. However, in cosmic terms, this estimate is a dramatic advance of the previous prediction from 10 to the power of 1,100 years, made by Falcke and his team in 2023.

“The final end of the universe occurs long before expected, but fortunately it is still a long time,” said Heino Falcke, a theoretical astrophysicist at the University of Radboud in the Netherlands, who directed the new study, in a a a a a a a a a a a a a a a a a a a a a a a aaaaaa atmentmenmment.
The new calculations of the team focus on predicting when the most durable celestial objects of the universe, the bright remains of the dead stars, such as white dwarfs and neutron stars, will finally fade.
This gradual decay is driven by Hawking Radiation, a concept proposed by physicist Stephen Hawking in the 1970s. The theory suggests that a peculiar process occurs near the event horizon, the point without return, around black holes. Normally, virtual pairs or particles are constantly created by what are known as quantum fluctuations. These pairs of part enter and leave existence, annihilating each other. Near a Black Hole events horizon, however, the intense gravitational field prevents such annihilation. Instead, the pair is separated: one part, one that transports negative energy, falls into the black hole, reducing its mass, while the other escapes space.
On an incredible high quality of time, Hawking theory suggests that this process makes the black hole evaporate slowly and disappear anglely.
Falcke and his team extended this idea beyond black holes to other compact objects with strong gravitational fields. They discovered that “evaporation time” or other objects that emit Hawking radiation depends solely on their densities. This is because, unlike the evaporation of the black hole, which is driven by the presence of an event horizon, this more general form of decomposition is driven by the curvature of the space hour itself.
The new findings of the team, described in an article published on Monday (May 12) at the Journal of Cosmology and Astroparticle Physics on Monday (May 12), sacrifice a new estimate for how long it takes white dwarf stars to dissolve in nothing. Surprisingly, the team discovered that neutron stars and black stellar dough holes break down during the same time: approximately 10 for the power of 67 years. This was unexpected, since black holes have stronger gravitational fields and it was thought to evaporate faster.
“But black holes have no surface,” Michael Wondrak said in the statement, a postdoctoral researcher of astrophysics at the University of Radboud and co -author of the study. “They reabsorb part of their own radiation, which inhibits the process.”
If only white dwarf stars and black holes dissolve angelly at all, what does that say about us? It may suggest that the meaning is not found in permanence, but in the brilliant brilliant asking questions such as the thesis, while the stars continue to shine.
