New #Supernova Type Sheds Light on Universe's Origins

Scientists have discovered a third type of supernova that could explain the universe’s previously puzzling abundance of calcium—which enabled the evolution of life—as well as eliminate at least one reason to hypothesize the existence of dark matter. Look for new theories on the origin of life without the need for dark matter over the next three years. R.C.J.

Standard astronomical theory maintains that all the elements heavier than hydrogen and helium were created and dispersed by supernovae of two different types: hot, young giants that explode in a violent display and then collapse under their own weight; and very old, dense, white dwarves that explode in a thermonuclear explosion. Unfortunately, the universe as we know it has many more heavy elements—like the calcium that makes up your body—that cannot be accounted for by those two types of supernovae.
Now astronomers at the Weizmann Institute of Science (Israel) claim to have discovered a third type of supernova that could account for the abundance of calcium in the universe—as well as eliminate one reason to postulate "dark matter."
