The ever-increasing number of deaths due to coronavirus infection, Covid-19, has led many of us to question our mortality. Still, most of us are not too worried about the end of the world happening anytime soon.
And we can continue to rest easy since the end date of the universe is far away, even though a scientist has figured out when and how the universe will end.
It happens sometime over the “few trillions of years”, according to physicist Matt Caplan. The end of the world as we know it will not come with a bang. Most stars “melt slowly, as their temperature drops to zero,” he says.
Describing it as “a bit of a sad, lonely, cold place”, Caplan said in a statement that no one around will see this farewell in the future.
“It’s called ‘heat death’, where the universe is usually black holes and burning stars,” said Illinois State University physics professor, whose research was published in the journal Monthly Notices of the Royal Astronomical Society.
In the search, Caplan looked at possible stellar explosions and found that, even in the midst of the darkness, there could be silent fireworks or explosions of the remains of unstoppable stars. was supposed to explode. Many white terriers may explode in a supernova when everything else in the universe has died and gone silent. As they become denser, these stars become “black stars” capable of producing iron in their coriander.
According to NASA, a supernova is the explosion of a star while a white dwarf is a star near the end of its life that has consumed most or all of its nuclear fuel and has fallen in size similar to Earth. .
“Stars do not have less than 10 times the weight of the sun’s mass to form iron in their corrugations as large stars do, so they cannot explode into supernova. right now, ”said Caplan. “As white fingers cool over the next few trillion years, they will diminish, eventually freeze, and become ‘black’ stars that no longer shine.”
Since iron cannot burn stars, it accumulates as a poison, causing the star to fall creating a supernova.
According to Caplan ‘s calculations, the theoretical explosions he calls “black dwarf supernovas” will begin in about 10 to 1100 years.
“In a year, it’s like saying the word ‘trillion’ almost a hundred times,” he said.
And not every black dwarf will explode either. Caplan said that only the largest black dwarfs would blow, about 1.2 to 1.4 times the mass of the sun. ”
In numbers, this means that as many as one percent of today ‘s stars, around a billion trillion stars, will explode like this.
Caplan has calculated that the largest black dwarfs will explode first, followed by smaller stars, so that after about 10 ^ 32000 years there will be no more left to go. At that point, the universe may be dead and silent.
“It’s hard to imagine anything coming after that, a black supernova may be the last interesting thing to happen in the universe. They may be the last supernova ever, ”he said.
