Pizza
The pizza is not, by conventional metrics, a fast object. A delivery driver might achieve 50 kilometres per hour in urban traffic. A thrown pizza slice, in moments of domestic discord, might briefly reach 30 kilometres per hour before succumbing to gravity and aerodynamic instability. The pizza makes no claims to velocity; its speed is measured in minutes to delivery, not kilometres per hour.
Rocket
The rocket exists in an entirely different velocity paradigm. The Space Launch System achieves speeds of 39,000 kilometres per hour. The Parker Solar Probe, humanity's fastest object, reaches 692,000 kilometres per hour. Rockets routinely escape Earth's gravity, requiring a minimum velocity of 40,270 kilometres per hour. In the category of speed, the rocket is not merely superior; it operates in a realm the pizza cannot comprehend.
