In recent centuries, modern knowledge structures and narrative technologies have introduced concepts into public discourse that, despite widespread acceptance, warrant serious scientific and empirical reevaluation. One such concept is the theory of the existence of prehistoric giant species known as "dinosaurs." By examining biological laws and geological evidence, it becomes apparent that the natural existence of these creatures, as commonly portrayed, conflicts with fundamental scientific principles. --- 1. Physiology and the Limitations of Cardiac Function in Gigantic Creatures 1.1 Blood Pressure and Gravitational Force In large mammals like the African elephant, the heart must generate sufficient pressure to pump blood to the brain, typically around 200 to 260 mmHg. Considering a creature like the "Brachiosaurus," standing over 8 to 10 meters tall, the required arterial pressure would exceed 600 mmHg to circulate blood to the brain . Such extreme pressure would be incompatible with the structural integrity of blood vessels and cardiac tissues, leading to immediate circulatory failure. 1.2 The Square–Cube Law According to the square–cube law, as an organism's size increases, its volume (and thus weight) grows faster than its surface area. Doubling an animal's size results in an eightfold increase in weight but only a fourfold increase in bone strength . This disproportion leads to mechanical instability in the skeletal structure, rendering movement or even standing unfeasible for such massive creatures. --- 2. Geological Challenges in Fossil Preservation 2.1 Earth's Dynamic Surface and Sediment Instability Plate tectonics theory explains that Earth's surface is in constant motion, with continental plates shifting, sediment layers deforming, and erosion occurring unevenly . The likelihood of massive bones remaining intact and discoverable after tens or hundreds of millions of years is statistically minimal due to these dynamic processes. 👇👇👇
