What would happen if every star that is currently in the universe exploded?

Every star ASIDE from the sun.What would happen if every star that is currently in the universe exploded?The sky would be first much brighter than today and in the far future, after the debris ceased to shine, almost completely dark. But we could not experience this, becaus it would be billions of years in the future.What would happen if every star that is currently in the universe exploded?
Well, it would take *at least* 4.3 light years for us to know the closest one exploded; and, it'd be bad news for the Earth, depending on the type of explosion... Then, about every 1 to 2 years after that, we'd see the light of the next explosion, then the next, then the next, etc, up to about 13 billion years from now, when *finally* the light of the *last* explosion would reach us.



If Sirius (about 8.6 light years away) explodes, we're pretty much toast anyway.What would happen if every star that is currently in the universe exploded?Only stars with a mass more than 4.2 times that of the Sun can explode. This is known as the Chandrasekhar limit for the Nobel Prize winning astronomer from the University of Michigan who worked it out. Fewer than 10% of all stars are that massive.What would happen if every star that is currently in the universe exploded?
First of all, if every star exploded we wouldn't know for another billion yrs. After a billion yrs has gone by the night sky would be a whole lot brighter.What would happen if every star that is currently in the universe exploded?Whamo drain cleaner.What would happen if every star that is currently in the universe exploded?
There would be plenty of debris for a new generation of stars to be born.
The sky would be vey bright, and we'd get lots of gamma rays raining down on us.
