- A scientist has revised the figures to estimate when the universe will ‘die’, or fizzle without more star activity though.
- The last supernova will be a “black dwarf supernova”, which will be more of a fiber than an explosion, but it is still very far away.
- It will be vibrations over trillions of years before we even get close to that point, so it’s nothing we need to worry about at the moment.
From what scientists can tell about the motion of galaxies and other celestial bodies, the universe is expanding more and more. That’s good for now, but eventually the universe will reach a point where things are so scattered and far apart that interactions that generate heat and light are simply no longer possible, It’s called hot death, and it’s how much faith that the universe will die.
One scientist decided to scratch the theories and theorize if that could happen, with the “death” of the universe marked by the hottest supernova. The theoretical “black dwarf supernova,” will be nothing more than the massive explosions of stars observed today, but will be more of a fiber.
The study was conducted by Dr. Matt Caplan and was published in Monthly announcements from the Royal Astronomical Society. The “black dwarf” stars will not shine brightly as they produce a lot of heat, but fusion will still occur deep inside them, and will eventually lead to a boiling point and a supernova contrary to what scientists have noticed.
“Stars less than about 10 times the mass of the sun have the weight and density not to produce iron in their nuclei like mass stars do, so they can not explode in a supernova at the moment,” Caplan said in a statement. . “While dwarfs know to cool off over the next few trillion years, they will dimmer, eventually freeze and become ‘black dwarf’ stars that no longer shine.”
But not all black dwarfs will have what it takes to blow their top, so to speak. “Only the most massive black dwarfs, about 1.2 to 1.4 times the mass of the sun, will blow,” says Caplan. The rest, or about 99% of the stars, remain defined black dwarfs and never reach the point of a supernova.
By that moment, no one will be there to see it, Caplan says. ‘Galaxies will have scattered, black holes will have evaporated, and the expansion of the universe will have pulled all the remaining objects so far apart that no one else will ever explode. It will not even be physically possible for light to travel that far. ”
So, when will it happen? That is the good news, in fact, because the “death” of the universe is not expected to last very, very long. The first such black dwarf supernova will occur in 10 to the 1100s. “In years, it’s like saying the word ‘trillion’ almost a hundred times,” Caplan said. ‘If you wrote it out, it would take up most of the page. It’s mindbogglingly far into the future. ‘
