Nuclear Explosion, Moving Earth's Orbit? - Page 3

Oliron remember that we are speaking of a Planet. The amount of matter existing here on Earth is overwhelming. A meteor the size of new york wouldn't cause the earth to move significantly. But it would eradicate life on the surface of the planet for sure.

We are so delicate compared to this planet. Because of that we thing whatever could extinguish us would also harm the planet. But that couldn't be farther from the truth.
This rock we call home has been here for millions, billions of years. It can withstand a lot of pounding. We are the fragile ones.

A nice metaphor Carl Sagan used is :

If you think of Earth as a solid 1 meter diameter wooden ball. Then the earth's crust is the varnish layer.

Think of that. All you ever saw, every mountain, lake, valley and river is part of the varnish of earth. Would you think scratching the varnish of our wooden ball could cause a serious threat to if? Of course not.

No atomic explosion caused by man can ever scratch the surface of Earth. And the idea that it can is silly.

Significantly is the key word here. We are discussing even the slightest movement of the earth.

Well that was what I was trying to illustrate. Even a very big meteor couldn't move the earth, say one like the one that extinguished the dinosaurs. That kind of meteor had for sure more than 10km diameter.

So ... If a mass extinction explosion event, like a 10km meteor falling from the sky can't take Earth out of it's orbit, then no human caused explosion can.

Theoretically speaking, of course, if you remove enough mass from Earth it will eventually move. BUT the amount of matter you needed to take is astronomical. It's safe to say it's impossible. At least with today's science.

Comments: What about if something hit the moon and then the moon feel out of its orbit and then hit earth?

That would be kind of cool.

But if we are going into that extreme scenario why not just have aliens use a major tractor bean and crush the Moon right into the Earth's surface? Like something Spielberg never even dreamt of.


In that case:

If the moon hit the ocean, all the water would instantaneously vaporise (along with the atmosphere), and earth would became a huge fireball. Due to the kinetic energy involved, both earth and the moon would crack into a million pieces launching space dust through space at incredible velocities (near c).

Whatever was left would be molten rock (originating from earth's and moon's remaining matter). A huge, extremely hot ball of rock glowing and reshaping in the sky. As the millions of years passed it would, eventually cool down again.
From this point on it is necessary to make some calculations and guess some values to dictate if the remaining planet would still be round, but I think time and gravity would make the mass of hot rock round again.

One more spectacular thing could still happen:

If the kinetic energy of the impact was such that it annulled the angular speed of the remaining ball of plasma (let's call it a protoplanet), then the sun's gravity would pull this protoplanet towards it, and as there is no centrifugal force preventing it from going on a straight line into the sun's core, that would be where it would go!
The final destination of our protoplanet would be the center of the sun, where it would simply dissolve into our star's absolutly enormous body.

There!

What size meteor would it take to move the earth's orbit?

Isn't there some kind of experiment in France or some other place in Europe where they are creating a black hole or trying to? If that got out of control or grew that would most likely change more than earth's orbit.

Besides all that what could change the earth's orbit without causing damage? Could the sun getting bigger do it? it will probably be a few million years away but as the sun grows so will its gravitational pull.

Comments: Depending where on the sphere you detonate, and at what point in the ellipse around the sun we are at, what direction we are pointed, etc. Yes, every tap has an effect, the moon balances things out, but it is getting farther away, and it can be "tapped" as well.

NASA: Japan quake shortened Earth's day, shifted axis

The 9.0 magnitude earthquake that ravaged Japan also shortened Earth's day by just over one-millionth of a second (1.8 microseconds to be exact), according to NASA. It also shifted the Earth's axis by about 6.5 inches. Ref. Source 2
