Monday
Monday demonstrates a remarkably consistent velocity that defies all attempts at modification. The entity approaches at a rate of precisely one week per week, a speed that remains constant regardless of observer motion, psychological state, or desperate bargaining with cosmic forces. This temporal velocity has been verified across all populated time zones, maintaining its inexorable pace with astronomical precision.
The perceived speed of Monday's approach exhibits curious psychological properties. Research conducted at the University of Liverpool's Department of Psychological Sciences documents a phenomenon whereby Sunday evenings experience subjective temporal acceleration, with test subjects reporting that the hours between 6:00 PM Sunday and Monday morning pass at rates up to 300% faster than equivalent periods on other days. This perceptual distortion, known informally as the Sunday Scaries Effect, amplifies Monday's effective approach velocity in the human experience.
Once arrived, Monday demonstrates variable speed characteristics. Morning hours on Monday pass with glacial slowness, with workers reporting that the interval between 9:00 AM and 10:00 AM on Monday mornings feels equivalent to approximately 3.7 hours on a Friday afternoon. This temporal dilation effect gradually normalizes as the day progresses, achieving standard time perception by approximately 2:00 PM. Monday's approach speed: unstoppable. Monday's passage speed: deliberately torturous.
Shark
The shark achieves remarkable bursts of velocity that rank among the most impressive in the marine kingdom. The shortfin mako shark (Isurus oxyrinchus) holds the documented record at 74 kilometers per hour, making it the fastest shark species and one of the swiftest fish in any ocean. The great white shark (Carcharodon carcharias) can reach speeds of 56 kilometers per hour in short attack bursts, sufficient to breach completely clear of the water when pursuing prey.
This speed derives from evolutionary refinements spanning hundreds of millions of years. The shark's heterocercal tail provides asymmetric thrust, while the unique dermal denticles covering its skin reduce hydrodynamic drag by up to 8% compared to smooth surfaces. Some species, including the great white, have developed regional endothermy, maintaining elevated muscle temperatures that enable faster sustained swimming than their cold-bodied relatives.
However, shark speed comes with significant limitations. These velocities represent maximum burst capacity rather than cruising speed, which typically ranges from 3-8 kilometers per hour. Energy expenditure during high-speed pursuit is substantial, requiring recovery periods between attacks. Furthermore, sharks cannot travel on land, navigate urban environments, or pursue victims into office buildings. A shark's speed, while impressive, operates within strictly defined spatial parameters that Monday effortlessly transcends.
VERDICT
Raw velocity metrics yield a decisive advantage to the shark. When measured by conventional distance-over-time calculations, 74 kilometers per hour dramatically exceeds any speed that can be attributed to Monday's weekly approach. The shark can close a 100-meter gap in approximately 4.9 seconds; Monday requires seven days to traverse any distance whatsoever.
However, this assessment requires important contextualization. Monday's approach, while slow in absolute terms, exhibits zero evasion opportunity. No human has successfully outrun Monday regardless of their speed. Marathon runners, Formula 1 drivers, and supersonic jet pilots all experience Monday with identical inevitability. The shark can be evaded by simply remaining on land. Monday permits no such sanctuary. Nevertheless, by pure kinetic measurement standards, the shark claims this category through superior locomotion velocity.
