A comet hitting the earth

Giant Meteor hits Earth.We all die.Martians have a big laugh.

ZOMG METEOR!!!!!!!!!!!!!!! *runs out and buys david icke books*

well, lets see. earth has existed for billions of years. in that time countless meteors have impacted the surface. and in that time, not once has the surface of the earth turned to frikin lava. the worst a meteor has ever done was mass climate shift, which sucks for all living things, but amounts to little more than a mosquito bite as far as the planet's concerned. so, yes. this scenario only exists in his mind. 😬

as AC jokingly put it, japanese animators love to go way over the top. so instead of a rock, they threw a molten moon at the planet just to say "i wonder what it would look like if the impossible happened" . and it looks really cool, but so does alot of ridiculously exagerated animation to come out of japan. KAME!!!! HAME!!!! HAAAAAAAA!!!!!!!! 😛

Awesome. It looked like the dealth star at the end.

What is this dealth star you speak of?

the star of many many deaths. i hope that answered your question sir

well, it seems 'dealth' is an obsolete old-english noun meaning 'share dealt'. i must ponder this further.

The share dealt star of many deaths, the name alone frightens me

This theory is supported by the similarity between the composition of moon rocks and the Earth's crust, and also that the Moon has no differentiated core like the Earth.

This depiction of the impact is from one of the many sites on this theory. As all can see, this impactor is much bigger than the one in that darlin' movie.

You would think there would be some reminiscent of that in the present day world though with a crater that size, even if the terrain rearanged?

Actually, a leading theory today on the origin of the Moon is that about 4.3 gigayears ago, a Mars-sized planetesimal struck the young Earth, smashed up a good portion of the crust pretty good, sending loads of debris into space, which eventually aggregated in orbit to form our natural satellite.

yes, but doesnt this theory also answer to the theory that at that time the solar system was complete chaos and collisions were a constant occurance? even then, we only got hit once...if the theory is true. so what are the chances now?

Yes, this was when the Solar System was new and forming, with all kinds of nasty things zipping around. The chances of a Mars-sized body hitting now are virtually nil.

However...there is that asteroid, Ceres, which is about 600 miles in diameter (the "comet" in the movie at the start of this thread reminded me of a hot Ceres). It's not classified as a dangerous object, as far as we can tell...but, the Solar System is a big and often unpredictable place, and there are other very big rocks too, not just Ceres.

And this doesn't even begin to touch on the Oort Cloud, where being able to predict being hit by an actual comet is also virtually nil due to immense orbital periods. At least with asteroids from the Belt, we are dealing with much smaller, more predictable orbital periods. There could a huge comet out there, with an orbital period of 10,000 years, with our name on it. 😏
