Asteroids: Deadly Impact

Asteroids: Deadly Impact
45:00 | 1997

Categories: Science and Environment

Every year, millions of asteroids and comets or ''stray bullets'' streak through the skies, and tons of small meteorites strike our planet! Some 65 million years ago, dinosaurs were wiped off the face of the earth, in what many believe was the aftermath of a massive cosmic collision. Could something like this happen again? Scientists believe that the impact of an asteroid only a mile wide would be globally catastrophic. Join extraordinary geologist Eugene Shoemaker and his wife Carolyn who have remapped the heavens with their discoveries of more than 30 comets and hundreds of asteroids. Now that we know what's out there, how can we defend ourselves?

Okay..but where is the ROCK? Is it underground? We can easily detect if the rock is there (underground) so why aren't we talking about it?

Not all the way...They would have found the rock somewhere in the middle below the surface. How do we know all of these are made by an asteroid? Some might have been made by volcanic activity, physicist smarty pants :)

The world united has enough firepower to destroy a threatening alien object. The most destructive force known is the sun. That's what I would would worry about!

Would anyone survive even 5 miles down? Would it flip the earth to a geological pole shift?

It depends upon the size of the impactor and the velocity of the little beasty. Large enough or fast enough and it could make the impact unsurvivable at any location on earth. Fortunately as the impact gets larger the chances of one happening goes down so the chances of an earth destroying impact are very small while the chances of a city size destruction event is pretty high. Tunguska would have taken out a major city and that happened only 104 years ago.

This type of scenario was written about some 2000 years ago by the apostle John in his book Revelation. In Revelation 8 you can read John's understanding of the vision he saw. In studying this I have concluded that the possibility that is overlooked is a large asteroid colliding with the moon and the moon fragmenting and falling to the earth, specifically upon the Northern Hemisphere, possibly ranging from eastern North America into Western Siberia, Northern China. For the area the devastation would be complete. But as is the case with visions and prophecies, it is only a possibility, not a certainity.

I totally agree with you, and it is going to happen someday. Just we don't know when.

I feel that is why God gave the good book, so that when he let them discover the comets they could correlate it to the book of revelations and see Jesus is real and that they need the blood of Christ for their salvation and the repenting of their sins and that time is short... Why else would he let them have all the technology that they have, it is all like the tower of babel and the times of Noah, and Sodom and Gomorrah. Hopefully watching this movie will shake some people enough to let them listen to what the Holy Spirit is saying to them.

If this did happen you would not have only the debris to deal with. The moon itself effects many aspects of earth, so it could be something extremely climatic. As expected if something did truly happen.

Megan Brown Climatic? Weather related? Climactic maybe? How about global extinction including ours? The moon is 1/6 the size and mass of the earth. The earth has 6 times the gravitational attraction and 6 times the moon's gravity that earth projects into the solar system, attracting 6 times as much space detritus. We must therefore, if there is logic, accept that we are hit six times more often than the moon. The earth impacts are erased by mechanical weathering systems, and the fact that ~3/4 of the earth is covered by ocean water so that impact craters cannot be normally seen. It is scarier than you can imagine.

The asteroid theory is just that, a theory. It is in question by a number of other experts.

Just how much proof do you require? You can see the holes in the ground, the shocked quartz and then you can look through a telescope and see the little beasties that caused it. You can also see the history of past extinctions and read about Tunguska. If there are experts who question the "theory" then I must question their sanity.

I hope astronomers can give us enough warning where the meteor will hit us so I can run around to the other side of the Earth.
