I think this video is appropriate for this topic.
Thanks! Context of the video below, really makes one think.
Carl Sagan wrote:From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.
Seen from 6.1 billion kilometres (3.7 billion miles), Earth appears as a tiny dot (the blueish-white speck approximately halfway down the brown band to the right) within the darkness of deep space.

Amazing that a 1970's technology Space Probe can still transmit data today. Imagine a couple billion years from now, when a piece of our "Time Capsule" is discovered!

Except the 1970 space probe travelled through a black hole, went through time, crash landed into earth at 1 million miles an hour, wiped out the dinosaurs, and will be discovered in 5 years.

I just blew your mind.

Okay how is this for scale?

Close Encounters or didn't one of these kill the Dinosaurs?
An asteroid larger then an Aircraft Carrier will be passing by Earth INSIDE the Moon's orbit on November 8, 2011. Though it poses no threat, considering the size of just our Solar System that is close! It makes a return trip after swinging by Venus in 2041. :shock:

Is there a preventative measure if one of these actually might strike the Earth? :?:
Wiki wrote:http://en.wikipedia.org/wiki/2005_YU55

On 19 January 2029, 2005 YU55 will pass about 0.0019 AU (280,000 km; 180,000 mi) from Venus. The close approach to Venus in 2029 will determine how close the asteroid will pass the Earth in 2041. The uncertainties in the post-2029 trajectory will cause the asteroid to pass anywhere from 0.002 AU (300,000 km; 190,000 mi) and 0.3 AU from the Earth in 2041. Radar astrometry in November 2011 should clarify the Earth encounter situation in 2041 and beyond.
Scientific American wrote: http://www.huffingtonpost.com/2011/11/0 ... 71988.html

The asteroid, designated 2005 YU55, will pass Earth at a distance of about 325,000 kilometers, just inside the orbit of the moon. Asteroids come that close frequently, but 2005 YU55 is notable for its dimensions: 400 meters in diameter. NASA says the asteroid is the size of an aircraft carrier, but it's actually even larger.
Universe Today wrote: http://www.universetoday.com/90650/aste ... an-impact/

Although classified as a potentially hazardous object, 2005 YU55 poses no threat of an Earth collision over at least the next 100 years. However, this will be the closest approach to date by an object this large that we know about in advance and an event of this type will not happen again until 2028 when asteroid (153814) 2001 WN5 will pass to within 0.6 lunar distances. – Near-Earth Object Program, JPL

Nope. The preventative measure would be to blow it up, but we'd have to do so with it far out enough that it wouldn't be a rain of fire from all the debris, and I'm pretty sure we don't have any launch vehicles that can make said journey.

Well we can just blow up those debris. Explosions solve everything.

If we could hypothetically blow it up in time would the rain of fire from the debris burning up in the atmosphere be preferable to a more concentrated strike from the intact asteroid?

Assuming you enjoy being able to breath oxygen, no.

I think that the debris field would be fairly scattered enough so that only a small percentage would actually enter our atmosphere. Of course this is all dependent on the mass of the object. There are meteor showers pretty often and so far, I am able to go out and mow the lawn without a pressure suit. People tend to forget that an explosion sends debris across a 360 field and certain dynamics would surely send most of it back into space.
