Nuclear Explosion, Moving Earth's Orbit? - Page 4

Look at that we do not need a meteorite to strike the earth to cause a impact on the day and the axis of the earth. Powerful earthquakes do the same thing to a degree. IF we get enough strong earth quakes we could change the course of the day or cause the poles to shift'

Orbit Earths Moving Explosion Nuclear

Hi there.

Yes Nature doesn't need a meteor to do significant damage, but I feel obligated to remember that the force of the earthquake that shook Japan is equivalent to an energy release of 2.0 EJ (that's Exa-joule or 1.000.000.000.000.000.000 Joules ). A common measure of energy is the amount of T.N.T. Megatons. So 2.0 EJ equals to 476 Megatons of T.N.T.

To establish a comparison, the modern nuclear bombs have a energy release equivalent to 1.2 Megatons of T.N.T.

Bare in mind that if you explode 400 1.2 nuclear bombs in one place you don't get 1.2 * 400 times the release of energy, because much of the power of the blast will be cancelled out.

It's impossible for us, with current technology, to make an explosion the size of this earthquake (fortunately, I might add).

Commenting to the post of News:
On the source article it says the following:

Conclusion: The effect of a 476 Megaton explosion on the planet is... Null. That should be a shining solid proof of the durability of this rock we call Terra. And a testament to the fact that we are definitely of no consequence to it's standing.

This is all so interesting but it begs for me to ask the question then, what would it take to move the earth out of its orbit enough to have a noticeable effect?

Title: Effect of a bomb on

Comments: You: Actually, the fact of the matter is that the maximum energy of one of the modern nuclear bombs is 10...17 joules, compared to earth's rotational energy of 10...29joules. This means that the effect of one single nuclear bomb COULD affect earth's rotation by one trillionth... Then what happens with the combined energy of the bombs being exploded at night for so many long years.... ? The distance from the sun varies from 91 million miles to 93 million miles depending on whether the sun is at apogee and perigee, and we all know the effect that this has on earth's seasons. Add to this the fact that the inclination of the earths axis is what actually causes summer, autumn, winter and spring, and you will comprehend what I am speculating. The Indian ocean tsunami was generated by a 9.4 richter scale undersea earthquake with an energy of 10...22 joules or about 100,000 times that of the largest bomb. This caused the north pole TO MOVE one inch, and shortened the day by a few millionth's of a second. SO THERE IS SOME EFFECT... Even though minute. (You must read about ""A butterfly fluttering its wings in Japan, and causing a thunderstorm in South America""" - a change in weather on another continent - very highly unlikely, but the miniscule effect is there and can be calculated)

Maybe a nuclear explosion will never be able to alter Earth's orbit but I'm not sure if can't affect it's axis' inclination as well. Some scientists believe that catastrophic events already did it in the past, for instance the forementioned asteroid that supposedly caused the extinction of the dinosaurs. Does anybody have better informations on this?
