It is difficult to determine an exact number of nuclear warheads needed to end all life on Earth as it would depend on various factors such as targeting and the size of the warheads. However, it is believed that even a small fraction of the world's nuclear arsenal could potentially cause catastrophic global consequences.
If the sun's nuclear reactions stopped, it would eventually cool down and no longer emit light and heat. This would have far-reaching consequences for our solar system, as all the planets rely on the sun's energy for warmth and light. Life on Earth would cease to exist without the sun's energy.
Extraterrestrial life.
While the Amor asteroids are considered potentially hazardous due to their orbits that can bring them close to Earth, they are not currently considered the greatest threat to life on our planet. There are other factors such as climate change, pandemics, and nuclear warfare that are considered more immediate threats to life on Earth. Efforts are being made to monitor and track these asteroids to mitigate any potential impact risks.
The sun produces energy through nuclear fusion, a process where hydrogen atoms combine to form helium, releasing vast amounts of energy. This same process serves as the basis for nuclear energy on Earth, where nuclear power plants use controlled nuclear fission reactions to generate electricity.
If the sun never existed, Earth would not have its primary source of energy and light. This would lead to extreme cold temperatures and darkness, making life as we know it impossible to survive. The absence of the sun would also disrupt the gravitational balance in the solar system, affecting the orbits of planets and other celestial bodies.
It is difficult to provide an exact number, but experts estimate that as few as 300 nuclear warheads detonated in key cities could result in worldwide devastation, as the resulting nuclear winter would lead to widespread famine and loss of life. Efforts to reduce nuclear stockpiles and promote disarmament are crucial to prevent such a catastrophic scenario.
Life on Earth gets its energy from the Sun, which produces the energy through nuclear fusion.
A nuclear war, which would result in a nuclear winter and the end of most if not all of life on Earth.
The nuclear energy that is most important for life on Earth is the nuclear fusion that powers the sun. This energy is essential for providing heat and light, which support life on our planet. Nuclear fission, used in nuclear power plants, also plays a role in providing electricity for human activities.
It is impossible to accurately estimate the number of nuclear bombs it would take to completely destroy Earth as the amount would be so vast that it is beyond comprehension. Using nuclear bombs to destroy Earth would also have catastrophic consequences for all life on the planet.
There is a large Minuteman silo complex near where I live. Any serious attack would involve hundreds of warheads on that site throwing up enough fallout to make the area I live in devoid of life for decades and risky to enter for about 200 years.
We would probably all die. Most life on Earth would die, if not from the radiation, from the toxic dust cloud that would from in the atmosphere of the Earth, mostly blocking the sun's rays.
1.The sun is a huge ball of nuclear fusion. 2.We here on earth use nuclear fission to produce electricity. so the answer is 2.
It is currently impossible to blow up the Earth using nuclear weapons as the planet is too large and the energy required would be immense. Additionally, detonating a large number of nuclear weapons on Earth could have catastrophic consequences for all life on the planet.
Nuclear fusion occurs in the Sun's core, where hydrogen nuclei combine to form helium and release energy in the form of heat and light. This energy is then radiated outwards from the Sun, warming the Earth and other planets in the solar system. So, nuclear fusion in the Sun warms Earth from the outside by emitting radiation that travels through space to reach our planet.
It is difficult to provide an exact number as the use of nuclear weapons would have catastrophic global consequences, potentially leading to nuclear winter and widespread devastation. It is imperative to prevent the use of such weapons to protect life on Earth.
The only answer to this question may be answered in the next thousands of years. The earth does not function in decades, or millennia. It survives billions of years. Most nuclear episodes have a half life that are that equal multiple human life spans, but have repercussions over multiple earth organism life spans.
