Gold is one of the densest elements in nature. Blocks in minecraft are confirmed to be cubes a meter in width slash length. So, a cubic meter of gold would weigh around 19.3 tonnes. That sure is alot, but a god apple uses 8 blocks of gold to craft it. That would make a gapple weigh a hefty 154.4 tonnes, but you can stack golden apples. In one hand you can carry 9881.6 TONNES of golden apples. That's 21,785,198 pounds!
So... uh Steve=Strongest game character?
