https://www.afinalwarning.com/502741.html (Natural News) Small “snowflakes” of radioactive uranium that trigger massive nuclear blasts in space could help explain some of the universe’s more bizarre star explosions. According to theoretical physicist Matt Caplan, it is important to understand how these explosions occur for all sorts of applications, from the production of elements to the expansion of the universe. Caplan studies astromaterials – the solids that form inside dead stars – and examines their properties to better interpret astronomical observations of dead stars. In a recent paper he co-authored with fellow theoretical physicist Charles Horowitz, the two posited that atoms of uranium sink to the centers of aging white dwarfs as they cool. White dwarfs, also known as degenerate dwarfs, are the hot, dense core remnants of long-dead small stars. ....
https://www.afinalwarning.com/512629.html (Natural News) A new study published in the Physical Review Letters suggests that the remnant cores of dead average-size stars can explode like a nuclear bomb. Known as white dwarfs, these dense cores are packed with heavy radioactive elements called actinides that can spontaneously undergo nuclear fission – the splitting of atoms. Depending on certain conditions, these cores can eventually undergo uncontrolled fission, culminating in a massive stellar explosion known as a supernova. “The conditions to build and set off an atomic bomb seemed very difficult. I was surprised that these conditions might be satisfied in a natural way inside a very dense white dwarf,” Charles Horowitz, a nuclear astrophysicist from ....

(Photo : Peter Dopper) Death of the Miniature Stars As miniature stars die, they cool into husks of their old selves called white dwarfs. A recent study suggests that atoms of uranium sink to the core of these aging white dwarf stars as they cool, icing into snowflake-like crystals no larger than grains of sand. Illinois State University s theoretical physicist and study co-author Matt Caplan explained that these snowflakes can function as many of the tiniest nuclear bombs in the galaxy, becoming the force that breaks off the powder keg. ....
