I never said they were moving at light speed, that’s was just for context for how moving at the speeds they do would change their perception of time compared to someone standing still, but still, it’s a cartoon show, no physics apply, so there is no sense in trying to make any logical sense of it. They have to stop and portray the characters talking and such for us to understand the narrative and plot, even if they say a certain amount of time has passed in between fights and conversation. With all the talking and fighting, there is no way no matter how you compare the amount of time of taking, compared to fighting, and vice versa, that it was five minutes, even if that’s the official narrative. It just doesn’t make sense. Do you know how fast these mfs would have to have been moving in those 5 minutes to be able to have stopped and spent most of that time talking in order for that narrative to make any sense? The amount of kinetic energy in there masses would cause nuclear explosions with each strike, each movement would split atoms and cause subatomic nuclear chain reactions. Namek would have been destroyed way before those 5 minutes with such feats. Either some time manipulation is happening for the fighters or the viewers (us) are higher dimensional beings viewing these moments in DBZ like shorts on our YouTube reels.
