The entire Earth could be vaporized in just a fraction of a second if the supernova was close enough. The shockwave would arrive with enough force to wipe out our entire atmosphere and even our oceans. The exploded star would grow brighter for about three weeks after the explosion, casting shadows even during the day.
but dont worry it wont happen bez it will take billions of years
