Scientists claim they are “fairly certain” knowing how the universe will end, saying it will not be due to an explosion.
Scientists at Illinois State University revealed that the universe will end with stars that fade very slowly.
“It will be a sad place, lonely, a little cold,” said Dr. Matt Kaplan, who led the study, adding that it was possible that no one would be around to witness the official end.
Dr. Kaplan’s calculations indicated that the end of the universe would be very dark, but silent fireworks might punctuate it – explosions of remnants of stars.
While massive stars in the universe tend to have a dramatic explosive death, white dwarf stars tend to shrink slowly before they die.
Dr. Kaplan explained, “Stars with a mass less than 10 times the mass of the sun, do not have the gravity or the density to produce iron in their nuclei, the way massive stars do, so they cannot explode in a supernova at the present time. And when the white dwarfs have cooled over the years.” The next few, they will dim, eventually freeze, and become “black dwarf” stars that don’t shine.
Kaplan added that, like today’s white dwarfs, they will mostly consist of light elements such as carbon and oxygen, and they will be the size of the Earth but contain a mass equivalent to the mass of the sun.
“Stars shine because of thermonuclear fusion – they are hot enough to smash the small nuclei together to form larger nuclei, which release energy. White dwarfs are ashes, they are burning, but fusion reactions can still occur due to quantum tunneling, but at a slower pace.” Much. Fusion takes place, even at zero temperature, and it takes a really long time. “
Fortunately, Kaplan’s calculations indicate that we still have a long time to go before the end of the universe.
