9 billion years ago when the dinosaurs became extinct...

[shimshimheyxD]

You know how the comet that was about 7 miles wide hit the earth causing the extinction of dinosaurs? Do you think that impact might of moved the earth and took it off orbit and flew into a different orbit? (might be exageration but do you think the earth might of flew off into a different galaxy??) because space, has no gravity and something that moved in space goes on and on... Discuss..

Even if it did, we've been moving out of gravitational orbit since the Earth was formed.

The moon is slowly moving away every year

like a few feet or so

Yes. Think Newton's Third Law: For every action, there is an equal and opposite reaction. So, when the asteroid hit the Earth, the Earth's course moved slightly, likewise, the Earth pushed back on the asteroid, but the Earth's gravity overcame the opposing force (I think). But, even something that large wouldn't make a significant impact on the orbit of the Earth.

i think the real question is: if a meteor hit earth, did it bring new life?

It hasnt been proven that a comet was the reason dinosuars are extinct, a comet could of hit a volcano causing it to erupt upsetting all other volcanos there fore throwing alot of ash into the air killing the plants killing the palnt eaters and finnaly killing the meat eaters.

and its not called a comet its a meteor before being dissolved into the earths atmosphere, after its a meteorites.

That would still mean that it was an asteroid that killed off the dinosaurs...

if ur stabbed with a poisoned knife on ur ass, u survive the knife but the poison didnt go away, what killed you?

It was 65 million years ago. There was no earth 9 billions years ago

As for that question, the Earth's so huge it's the same as saying a stone thrown at a car would move it. No, would only scar it. It's called inertia, the laziness a body has to change it's speed (even if it's no speed at all.)

[Emperor Pan I]

your assuming the ab Asteroid even hit earth. That is just a theory, along with many others. One cannot begin to assume anything.

[TrongaMonga]

Countless asteroids (big ones) hit Earth in its begginings. Yet it did not move.

The posion is a result of the knife attack though. The dust storms were a result of the asteroid hit. They wouldn't have ever had happened if it had never hit.

p = mv people...

Doubtful the Earth would move out of orbit significantly. If you calculated the velocity change in the Earth after a 7 km wide comet hit. It would be be probably something to the -6 m/s. The Erath would be so insignificantly moved that it would be as if it did not move at all. The Earth's huge momentum would allow the Earth to continue moving in orbit. So no, it would not have moved to another galaxy unless the comet was moving ridiculously fast kinda like the speed of light.

BTW I don't really understand how comet crashing into Earth would be relevent to Newton's Third Law. The comet colliding to Earth was most likely a perfect inelastic collision.

Wouldn't they still be acting against each other? While the comet is hurling towards earth, the earth applies a gravitational force on comet, while the comet also applies a gravitational force in the opposite direction. When the comet hits the earth, the earth pushes back on the comet, likewise, the comet pushes back in the opposite direction. Newton's Third Law is still in effect... I think.

[Venice_native]

If there isn't any gravity in plain space I don't think it would, there could be gravity coming from the Earth but it'd be pulling it twords it, not away. But I also think once it entered Earth and came into a gravitational field it could.

lets say there is no meteor or meteroid and the volcanos explode then they die cuz of the volcanoes damn not everything has to be corrected man!

[Zerglite]

what was it... some hundred or so years ago, when a volcano so large errupted in indonesia or somewhere about, it sent so much ash out, that they called it "the summer without sun"

or something like that, im not too sure of what i just posted.

Let us refrain from posting about somthing with no information or details along side it.

That would make sense. You just stated that [that] happened as a direct effect of the asteroid hitting the Earth. But then what is your reasoning for every volcano to erupt? Because they wanted to?

[x42bn6]

I do not know the masses of the Sun and the radius of the orbit from the Earth to the Sun, so I cannot give a figure. However, the product of the mass of the asteroid and the speed (actually, velocity) of the asteroid must far exceed the mass of the Earth for any noticable deviation in change.*

Krakatoa. Yes, it's a possibility. Volcanoes can really cover the Sun in the entire Earth and end all life. But it takes a really huge explosion. That only happens once every lots of time.

And the Third Law of Newton is applied here as it is applied in every inelastic collision, and as it is applied with your own gravitional pull. Yes, you are pulling Earth to yourself as it (he/she?) is pulling you to it. But it's just too god damn big to do any difference.
