Compared to the energy contained in the earth, the power at the disposal of human beings has always been insignificant.
The earth will produce natural disasters due to factors such as its own energy release, solar activity and energy radiation, tidal movements, and changes in the natural environment caused by human activities, which can be roughly divided into geological disasters (volcanic eruptions, mudslides, ground subsidence, etc.), flood and drought disasters (floods, droughts, waterlogging), meteorological disasters (typhoons, hurricanes, sandstorms, etc.), marine disasters (sea ice, tsunamis, etc.), fires (forest fires, Grassland fires), these different types of disasters can cause losses in different situations, and the survivability of vehicles used by humans will vary depending on the type of disaster.
For example, if there is a super strong ** above 9 on land, the propagation distance of the ** wave will reach thousands of kilometers, even if the epicenter is located in the inland area, the coastal area is also likely to suffer losses, at this time, if there is a large aircraft flying in the earthquake area, it may be lost due to the paralysis of the navigation system in the earthquake area, or it is difficult to find the forced landing location due to insufficient aircraft fuel, and most of the airports in the earthquake area have been damaged or closed due to **, and the safety of passengers on the plane is in jeopardy.
However, if it is a tsunami, or if the ** level is low, then the equipment in the air can be well avoided from being affected. Like Air Force One in the United States, even if a nuclear war breaks out, it will be able to stand alone to a certain extent. However, this premise is that Air Force One must have a safe landing place for a certain period of time, because even if the United States has the world's largest fleet of tankers, Air Force One's engines cannot work continuously in the air.
And if a nuclear submarine is diving and suddenly encounters an underwater fault, then no matter how good the submarine's maneuverability and self-sustaining ability are, it is very likely that it will be damaged or even sunk due to improper disposal, on the contrary, the ground and air vehicles will not be affected.
Another example, in the seabed near the coast, in addition to affecting the coastal area, causing damage to ports and airports and other facilities, it will also produce violent water movements, seriously threatening the safety of all kinds of ships sailing on the surface and underwater, in this situation, whether it is aircraft or submarines in the disaster area, it is difficult to protect themselves.
As a result, the safety of different vehicles varies depending on the type and situation of the disaster, and when the scale of the natural disaster reaches a certain level, it is difficult for any vehicle to be immune.
However, if a war breaks out on the ground, or if a strong wind blows, then a nuclear submarine in the deep sea will have better survivability. As a better concealed underwater equipment, even in wartime, it is difficult to find a nuclear submarine that has dived to a depth of several hundred meters.
It can be seen that what kind of equipment can achieve "peace of mind" in the event of extreme natural disasters is still a topic of discussion. However, the answer is also obvious, and that is spaceships. As long as it can fly out of the earth, no matter what kind of natural disasters happen on the earth, it will not be affected. If human beings want to break free from the shackles of nature, they still have a long way to go, not only to have equipment from outer space, but also to have supply sites in outer space. For humanity, in 100 years, these things may no longer be out of reach.
However, for a large number of residents to flee the planet in the face of extreme natural disasters, a few hundred spaceships are not enough. The future facing humanity is full of unknowns, and it is a test of human wisdom to be fully prepared before the unknown comes. Although there are many transport aircraft, tankers and even stealth strategic bombers around the world, these first-class equipment are still prepared for war, not for responding to unknown natural disasters.
At the current stage, the contradictions between different countries cannot be resolved, the Russian-Ukrainian conflict, the Palestinian-Israeli conflict and even the friction in the Red Sea, although these will promote the production and even progress to a certain extent, but they are stumbling blocks to the rapid development of human civilization. If humanity had focused more on how to deal with natural disasters and how to find "spare land", perhaps there would have been fewer wars.
Although human civilization has developed for thousands of years, there are still great differences between civilizations in these thousands of years, otherwise there would be no religious conflict between Israel and the Arab world. Ethnic and religious conflicts are arguably the most terrible of all, involving confrontations between ethnic groups, battles between faiths, and it is incredible, on the same earth, why these things have not been resolved after so many years.
