How to use nuclear bombs to create suitable space?

A nuclear bomb is a weapon made by using the principle that nuclear fission or nuclear fusion releases huge energy. Although they are weapons, we can make them contribute to the human conquest of space and show their great power just like the peaceful use of atomic energy.

Cool down Venus.

Venus, known as the earth's sister star, has almost the same diameter (6050 km) as the earth (637 1 km) and a density of (5? 25 g/cm3) is slightly lower than the earth (5? 52 grams/cubic centimeter), with a rocky shell and internal structure similar to that of the earth, but Venus has an atmosphere composed of 97% carbon dioxide, which is much thicker than the earth, and the surface pressure is as high as 90× 1055 Pa. In particular, its surface is scorching sun and unbearable heat, and the temperature is 465 ~ 485 degrees Celsius. Obviously, Venus is not suitable for life on earth at all, and the primary task of transforming Venus into a human-like space migration site is to cool down.

Studies have shown that the heat transferred from the interior of Venus to its surface only accounts for 0? 5%。 The reason of its high temperature and high fever is the greenhouse effect of thick carbon dioxide. It turns out that carbon dioxide has exactly the same thermal insulation characteristics as a glass greenhouse, that is, it can let short-wave radiation such as visible light and ultraviolet rays of the sun pass unimpeded, but it can block long-wave radiation such as reflected infrared rays in all directions. Therefore, the only way to cool Venus is to reduce solar radiation, or to reduce the concentration of atmospheric carbon dioxide and weaken the greenhouse effect. And a nuclear bomb can just take this responsibility.

It is found that the solar radiation passing through the atmosphere will be weakened by the scattering of floating particles or the reflection of clouds, which is the so-called "parasol effect". Therefore, as long as a small amount of dust clouds are placed between Venus and the sun, the sunshade effect they produce can weaken or block part of the sunlight hitting Venus, thus achieving the purpose of cooling its surface. In front of the giant Venus, it is necessary to artificially lay a layer of dust cloud that blocks the sun, and its scale is incomparable to any modern project. Billions of tons of dust that need to be transported from the ground or excavated from the moon and asteroids are obviously not worth the candle. The best way is to use nuclear bombs to take local materials. Some people imagine that as long as a certain number of nuclear bombs are detonated on Venus, a huge dust fog can be created in the atmosphere of Venus, which is enough to weaken the sunlight hitting Venus. When the solar radiation is reduced to 50% ~ 80%, the temperature of Venus will begin to drop at a rate of 1 ~ 3 degrees Celsius per week. In a few years, the climate of Venus will become as warm and mild as that of the earth.

As early as 1952, a scientist named Yuri found that carbon dioxide gas in the air would be absorbed by rocks when the ambient temperature was low. When the temperature rises, the carbon dioxide gas in the rock will be released automatically. Therefore, once the temperature of Venus drops, the sticky carbon dioxide gas in its atmosphere will be gradually absorbed by the rocks on Venus, and the greenhouse effect will be weakened. In this way, cooling Venus with a nuclear bomb can not only reduce solar radiation, but also kill two birds with one stone, reduce the concentration of carbon dioxide and weaken the greenhouse effect, thus eradicating Venus' "high temperature disease" once and for all.

Warming Mars

The rotation period (24 hours and 37 minutes) and declination angle (23 degrees and 59 minutes) of Mars, the nearest neighbor of the earth, are very similar to those of the earth, which makes Mars have the alternation of day and night and the cycle of four seasons. However, the Martian atmosphere, which is composed of 95% carbon dioxide, is extremely thin, with an average air pressure of 6 10 Pa and no liquid water, and the average surface temperature is only MINUS 60 degrees Celsius. Its harsh environment is even worse than the moon, and it is obviously not suitable for the survival of life on earth. To immigrate to Mars on a large scale, we must also transform it. Contrary to Venus, Mars needs to "warm up".

The reason is that the temperature of Mars is low mainly because it is farther away from the sun than the earth, and it receives at most half of the sun's heat. Secondly, the heat insulation of its thin atmosphere is too poor. Therefore, some scientists intend to increase the concentration of carbon dioxide in the atmosphere of Mars to strengthen the greenhouse effect and make Mars warm. To accomplish such an important mission, people will naturally think of nuclear bombs.

It has been suggested that a nuclear bomb should be thrown at the silent crater on the surface of Mars, triggering the eruption of Mars volcano. It is estimated that a nuclear bomb with 6.5438+100,000 tons, if its landing point is accurate, will be enough to stimulate the underground magma source of Mars, causing several volcanoes to erupt at the same time. By then, the rosy sky of Mars will be filled with carbon dioxide and water vapor. When these gases reach a certain concentration, the solar heat can still reach the surface of Mars, but the heat reflected by the surface is blocked in the atmosphere and cannot escape. In this way, the temperature of Mars will continue to rise.

It is also assumed that an asteroid between Mars and Jupiter will be blown off the orbit by several million-ton nuclear bombs and hit Mars. A violent impact will release a large amount of greenhouse gases trapped underground on Mars, thus heating up and warming it.

Consolidate the land

It has a long history to discover that comets, asteroids, meteorites and other near-earth small objects and their fragments have impacted celestial bodies in the solar system, including the earth. The extinction of dinosaurs 65 million years ago, craters and craters densely distributed on the surface of celestial bodies, and countless craters on the earth are masterpieces of celestial collision. 1The "comet hitting the wood" witnessed by human beings from June 6 to July 22, 994 shows with irrefutable facts that the impact of small celestial bodies on the earth has become a "public hazard" affecting human survival, just like earthquakes and environmental pollution. However, humans can use nuclear bombs to strengthen the earth and eliminate this disaster from the universe.

On the basis of observation, search and accurate prediction, there are two ways to use nuclear bombs for defense:

One is to detonate a nuclear bomb and blow up "uninvited guests" who dare to offend the earth. British scholars believe that using a rocket with a nuclear bomb to intercept and make the nuclear bomb explode on the "intruder" to vaporize it can eliminate the catastrophe from the sky. In addition, you can also bury a nuclear bomb on a small celestial body and detonate it regularly.

The second is to change the orbit of small celestial bodies through the explosion of nearby nuclear bombs to avoid meeting the earth in a narrow way. Thomas arens and Allen Harris of the California Institute of Technology and the Jet Propulsion Laboratory of the National Aeronautics and Space Administration pointed out that a nuclear bomb smaller than the one dropped in Hiroshima, Japan in World War II, can generate enough impact force to make the "attacker" change its running direction.

Mushroom clouds produced by nuclear explosions

Of course, the size and texture of small celestial bodies should also be considered when choosing nuclear bombs and methods. If the "attacker" is not big, it can be detonated with a general small equivalent nuclear bomb; If the diameter is more than 2 kilometers, you have to use 654.38+00,000 tons of nuclear bombs; If it is an iron or rock asteroid, you have to ask the neutron bomb to "come out of the mountain". The neutron bomb exploded near a small celestial body, and the neutron drilled into it at high speed caused the temperature of the star to rise sharply, and some substances gasified, resulting in volume expansion and ejection from the other side of the star. The generated reverse thrust will make the star enter a new orbit far away from the earth.

Because after a nuclear bomb shatters a star, there is a danger of debris falling to the earth and causing a second impact, scientists suggest that it is best to launch a destructive nuclear bomb on a small celestial body about 10 years before it reaches the earth, and the nuclear bomb itself must be detonated on the small celestial body.

Of course, using nuclear bombs to transform the universe is an extremely grand project, which can only be realized on the basis of high technology such as spacecraft, high-thrust rockets, space stations, lasers, large computers and robots. In addition, the possible negative effects and unpredictable consequences during and after the transition should be carefully considered in the implementation process.

Jingwei fills the sea, the Goddess Chang'e flying to the moon, and we humans have turned many myths into reality. I believe that in the near future, nuclear bombs will certainly be able to show their talents in space and benefit the universe and mankind.

Short-wave radiation of the sun

Generally, the wavelength of an object's outward radiation is inversely proportional to its temperature. Generally, the higher the temperature, the shorter the wavelength of its strongest radiation, and the lower the temperature, the longer the wavelength of radiation. The surface temperature of the solar photosphere is about 6000 K, and about half of the energy in solar radiation is distributed in 0? 4~0? In the visible region of 76 microns, most of the remaining half is in the near infrared region and a small amount is in the ultraviolet region. Compared with the radiation of the earth, the wavelength of solar radiation is much shorter, so solar radiation is called short-wave radiation.
