Whales can dive 2,000 meters with their flesh and skin, why can't submarines made of steel alloy?
In the deep-sea world, whales are breathtaking with their amazing diving abilities. They can dive to depths of up to 2,000 metres on the ground with their flesh and blood, compared to submarines made of steel alloys, which often face many challenges when exploring the deep sea. Behind this phenomenon lies a profound difference between biology and engineering, as well as differences in the ability of nature and man-made products to adapt to extreme environments.
First of all, the whale's ability to dive stems from its unique physiological structure and biological adaptability. The whale's bones are thin and elastic, able to withstand tremendous water pressure without breaking easily. At the same time, their muscle tissue has undergone a long period of natural evolution to become extremely tough and elastic, and they are able to quickly adjust their volume and density during diving and ascending to maintain pressure balance in the body. In addition, whales also have an efficient respiratory system, which is able to store enough oxygen during diving, and through special physiological mechanisms to slow down the rate of metabolism and reduce the need for oxygen.
In contrast, although the submarine uses advanced steel alloy materials, it is still unable to cope with the deep-sea high-pressure environment. Although steel alloys are strong and durable, they are prone to deformation and fracture under deep sea pressure, thus threatening the safety of submarines. In addition, the internal structure and systems of the submarine are also far less flexible and efficient than those of the whale. For example, the power system of a submarine requires a lot of energy to keep running, while a whale can use its own muscular strength to drive its body to dive.
In addition to structural and physiological differences, there are also significant differences in environmental adaptation between whales and submarines. As creatures that live in the ocean for a long time, whales have adapted to various extreme conditions in the deep-sea environment, including low temperature, high pressure, low oxygen, etc. Submarines, as artefacts, can simulate these environments through technical means, but they still need to be cautious when facing a real deep-sea environment.
It is worth noting that despite the limitations of submarines in deep-sea exploration, mankind has made many remarkable achievements through continuous technological innovation and the spirit of exploration. For example, with the continuous development of materials science and deep-sea technology, mankind has been able to create more advanced and durable deep-sea probes that can withstand greater water pressure and harsher environmental conditions, opening up more possibilities for deep-sea exploration.
Looking to the future, with the continuous progress of science and technology and the in-depth understanding of the deep-sea environment, we have reason to believe that mankind will be able to break through more technological difficulties and achieve deeper and more extensive deep-sea exploration. In this process, the physiological structure and biological adaptability of whales will also provide us with valuable inspiration and reference.
In summary, whales can dive 2,000 meters with their flesh and skin, while submarines made of steel alloy cannot, and the reasons behind this involve profound differences between biology and engineering, as well as differences in the ability of nature and man-made products to adapt to extreme environments. By delving deeper into this topic, we can not only better understand the diving mechanics of whales, but also draw inspiration and inspiration from them to promote the development and advancement of human deep-sea exploration technology.
