No, Whitebeard, also known as Edward Newgate, cannot destroy the entire One Piece world. While he was a powerful and revered pirate, known as one of the Four Emperors, his strength was limited to his own abilities and those of his crew. While he had the power to cause massive destruction and impact on a regional scale, it would not be possible for him to single-handedly destroy the entire world of One Piece. The world of One Piece is vast, consisting of multiple continents, islands, and powerful entities.
