Universe wants that

He universe He is ready to die much faster than was previously thought, according to a new research by Dutch scientists.

But there is no great need to panic. We still have 10 to the power of 78 years before it happens, it is one with 78 zeros.

However, that is an important review of the previous estimate of 10 to the power of 1,100 years, says the research work of the University of Radboud, published in the Journal of Cosmology and Physical Astroparticle.

“The final end of the universe will arrive long before expected, but fortunately it has been for a long time,” said principal author Heino Falcke.

A trio of radboud scientists set out to calculate when the most “durable celestial bodies” – White dwarf stars – Eventually I would die.

They based their calculations on the Hawking radiation, which are named after a British physical famous Stephen Hawking.

Hawking nominated in the mid -1970s that black holes filter the radiation, slowly dissolving like aspirin in a glass of water, giving them a finite life.

Radboud scientists extended this to other objects in the universe, calculating that the “evaporation time” depends on the density.

This allowed them to calculate the theoretical solution of the most durable body, the white dwarf.

“As these types of questions and observe extreme cases, we want to better understand the theory, and maybe one day, we can unravel the mystery of Hawking radiation,” said co -author Walter van Suijlekom.

Humanity should not worry too much about the end of the universe. Unless we escape from planet Earth, we will have gone.

Scientists think that our sun will be too hot for life in approximately one billion years, boiling our oceans.

In about eight billion years, our star will eventually expand towards Earth, finally engulfing our sterile and lifeless planet and condemning it to a burning death.

Shed light on dark energy

Research occurs only weeks later Scientists published new findings That can also shed light on the fate of the universe. The researchers in March said that the new data show that dark energy, a mysterious force that represents almost 70% of the universe, can actually weaken.

If dark energy is constant, an idea introduced for the first time by Albert Einstein In their theory of relativity, scientists say that our universe can continue to expand forever, more and more cold, more lonely and even. If dark energy is reduced over time, the universe could someday stop expanding and then finally collapse on itself in what is called The “great crunch.”

“Now, there is the possibility that everything comes to an end,” said the cosmologist and collaborator of Studies Mustapha Ishak-Boushaki of the University of Texas in Dallas. “Would we consider something good or bad? I don’t know.”

Other efforts worldwide have an eye on dark energy and aim to free their own data in the coming years, including the Euclid Mission of the European Space Agency and the Vera C. Rubin Observatory in Chile.

Run in 2023, the Euclid Space Telescope of $ 1.5 billion of the ESA is equipped with a primary 11 -foot mirror of 11 inches almost perfect and two instruments: a visible camera of 600 megapixels and an infrared spectrometer of 64 megapixel infrared. The field of vision of the telescope is approximately twice the size of the full moon.
