This won’t happen for trillions of years, if it ever does, but explosion of a black dwarf supernova will destroy the whole Universe, according to Illinois State University theoretical physicist Dr Matt Caplan. Only about one per cent of all the stars in existence could die this way. “Stars less than about 10 times the mass of the sun do not have the gravity or density to produce iron in their cores the way massive stars do, so they can’t explode in a supernova right now,” said Professor Caplan. The universe will be a very different place at that time and probably Earth will likely be gone along with everyone on it.

“Galaxies will have dispersed, black holes will have evaporated, and the expansion of the universe will have pulled all remaining objects so far apart that none will ever see any of the others explode,” Dr Caplan said. It’s estimated the first of these theoretical explosions will happen in about 10 to the power 1100 years (like saying the word ‘trillion’ almost a hundred times). “It’s hard to imagine anything coming after that, black dwarf supernova might be the last interesting thing to happen in the universe,” Dr Caplan said. The article has been accepted for publication in the Monthly Notices of the Royal Astronomical Society.
