On a christian site I saw a model of earth that showed that the earth was miracuously protected from large,damaging continuously moving debris in space, unlike otgher celestial bodies in space. I want to know more.

Actually, it's mostly the planet Jupiter that protects Earth from constant bombardments of astroids and comets from the outer solar system. Because Jupiter is so much more massive, its gravitational influences is quite significant. Most objects approaching the inner solar system will invariably be influence by Jupiter in one way or another, i.e. their orbits altered or even become captured and consumed by Jupiter.

Christians and most religious groups of people don't seem to want to understand how truly the world works. God is just an expedient answer to everything they don't know or understand. If you truly want to learn about the Universe God created, don't waste your time on their websites. Because they can only tell you that God did this, God did that, which really is the same as saying I don't know and I don't care.

I think what you mean is that we have been protected the last 65 million years from a very large and catastrophic impact from a enormous pieces of debris. We do get bombarded from small metors and various space debris that burn up in our atmosphere. Our planet isn't the only one though. Venus has a very potent atmosphere. The universe consists mainly of space and the chances that something large enough to cause a disaster is in the multi trillions. I do, however, believe that God had his hand in the beginning of all things and shaped everything in such a way that is scientifically infallible. Everyone perceives the hand of God differently and there is really no right or wrong answer. If you believe it to be true then it is. And don't let Christian hating hippies tell you there is no God because there is.

Well, Earth is always hit by objects from space. Most are small and burn in the atmosphere before hitting the ground. Moon has a lot of craters because it does not have an atmosphere. There are large colisions though, such as the one that caused extinctions of dinosaurs 65M years ago and others that left large craters. A lot of objects in the solar system are caught by Jupiter's gravity, since it is the heaviest planet. Recently pieces of a large comet have crashed into Jupiter.

Earth is continuously hit by things zipping through space. Most of those things are small and burn up in our atmosphere before they do any damage, and when we see them, we're supposed to make wishes or something. As for other celestial objects in space that show evidence of major collisions...well...we're seeing signs of major collisions becuase those bodies don't have atmospheres that cause coliding objects to burn up due to friction.

Occasionsally the earth is hit by something that leaves a pretty impressive smack. The meteor crater in Arizona is one such example, and there are other craters scattered around the globe, the remnants of one fairly large one has been found in the Gulf of Mexico. There's also the Tunguska blast that flattened trees and made a LOUD boom in Russia in 1908, that blast is shown to have been a bolide (explosive meteorite). So yeah, I guess if the earth IS protected by the hand of God, he needs to clench his fingers a bit more, because stuff gets through every day.

Also, Earth is pretty small and not that massive...at least compared to the real whoppers out there...Jupiter and the sun. Big nasty things are more likely to hit them because their gravitational footprints extend a lot farther out than Earth's.

Yes it is the hand of God, and yes there is a very scientific reason behind it. It is due to electromagnetics, the relationship of the electrons in our atmosphere and the charge on those electrons with "ether" or dark energy. Email me if you want to know more about it, but seriously don't listen to these dumbasses. Meteors and comets don't hit us for a reason. People think they have, and they point out "impact" craters all over the Earth, but many of those were actually caused by massive lightning bolts. The ones our ancient ancestors talked about being hurling around all the time, rocking the planet.

Apparently God had something better to do on June 30th, 1908. We're just lucky that it didn't strike somewhere near a large population.

Also, in the history of the earth, there have been six major extinction events. Two of which are thought to have been the result of an large asteroid impacting the earth. Give the universe some time. I'm sure it'll wipe us out just like it did the dinosaurs if we don't wipe ourselves out first. :)

Your Christian site is mistaken. We are bombared with space material on a daily basis. No, we haven't been hit by anything large in a while, but we also have a very thick atmosphere that burns up most large objects to relatively harmless size. We'll get hit by something big one day. It's quite inevitable.

As some of the answerers stated above, E.L.E. level asteroids are cyclic. It's an astronomical certainty that we'll be hit by another one, in fact, we're overdue for a 10-km size hit.

Regarding the hand of god, we're still being hit at the following rates:
Pea-size meteoroids - 10 per hour
Walnut-size - 1 per hour
Grapefruit-size - 1 every 10 hours
Basketball-size - 1 per month
50-m rock that would destroy an area the size of New Jersey - 1 per 100 years
1-km asteroid - 1 per 100,000 years
2-km asteroid - 1 per 500,000 years

The suggestion is idiotic, a fairly large asteroid entered the earths atmosphere and blew up high in the atmosphere during the first gulf war, to seismometers it looked like a nuclear explosion.

We've been lucky so far, it won't last forever. Fundamentalists care nothing about real world knowlage, listening to them is dangerous.

Oh sure it is...just ask the dinosaurs!

The Earth is 4.5 billion years old, and during that time most of the large junk has already collided with us (and other planets/moons).

But there's still plenty of stuff out there. We could be hit by a killer asteroid or comet any day now. It's just a matter of time before it happens again.
