Wizard:  So , Superman 's feats and skills are definitively measured . However , Goku 's are not and are difficult to judge . Not only does Dragonball heavily abuse cinematic time , but Goku 's final adventures in Dragonball GT are incredibly inconsistent due to his untimely transformation into a child . As ki is dependent on the physical body , his child form likely could not handle his own ki , sending his power into flux .
Boomstick: And obviously , we 're not using future Goku 'cause that would require a ridiculous amount of assumption . Not to mention we 'd have to use future Superman , who 's pretty much God . So , like Superman , we need to judge Goku in his prime .
Wizard: After experimenting with dozens of different theories , we discovered an iron - clad method to finding Goku 's limits , which we call the Gravity Formula , based around his training in increased gravity . Due to his style of training and Saiyan heritage , Goku increases his abilities proportionate to the amount of force he trains under . While in base form , Goku could lift just under 40 tons . This is equivalent to 586x normal Earth gravity , which we will use in the Gravity Formula along with the Super Saiyan multipliers to calculate Goku 's maximum potential .
Boomstick: Multiplying the 40 tons by the Super Saiyan forms means he can lift up to 160000 tons in Super Saiyan 4 , strong enough to pick up a continent ... or my ex - wife . Ha ha ! Right after Goku trained on King Kai 's planet , which has gravity 10x stronger than Earth 's , he flew across Snake Way Road as fast as possible to save his friends . It took him 28 hours , impressive since that 's 1000000 kilometers long .
Wizard: Except it 's filled with curves and Goku flew straight over it , so how far did he actually travel ? By comparing Goku 's height to a single spike , we can measure each curve . We can then remove those curves from the overall length . So it turns out that Goku actually flew 307000 kilometers , nearly 11000 km / h .
Boomstick: To see how fast his base form is at the end of the series , we run the Snake Way number through the gravity formula to find that his top speed clocks in at over 2 1/2 billion km / h , over 2x the speed of light .
Wizard: We can determine Goku 's durability through this bomb , which the brilliant Dr. Gero designed to kill Goku at age 25 , when his maximum potential was Kaio - Ken x4 .
Boomstick: Scans of the bomb display a TNT measurement of _ 657 _ . Bulma says the bomb could destroy the Earth , so this is likely measured in quadrillion megatons , since it takes at least 53 quadrillion megatons of force to destroy the Earth .
Wizard: So in his final form , Goku can survive up to nearly 35 sextillion megatons .
Boomstick: Goku does n't rely solely on his physical abilities . He amplifies his strength and durability with ki .
Wizard: But even though his ki reserves can not be measured , we can determine his maximum output . See , his ki attacks do not force him backward unless he allows them to .
Boomstick: Even when firing upward at full power , the ground beneath him remains untouched .
Wizard: Therefore , according to physics , his maximum output is at most equal to the amount of force he can withstand .
Boomstick: Luckily , we just calculated that with the Gero bomb .
Output: measurement
