Thanks for sharing, Gary... this brought back fond childhood memories of my Aunt Margaret belly-flopping into the pool.

...back to work on my JABB chart and RK lessons.

What'd she say? :p

[RichR]

Well, that would ruin your day, year, life, millenium, eon, whatever!

[Styxx]

Man! Thatsa One Spicey Meataballa! :D

[JonFairhurst]

Hey, I can see my house from here!

Oh. Nevermind...

[Leaf]

Allow me to translate. She said "Ohh... my goodness this looks like a rather large meteor and it's maybe going to crash into the earth." Then she said "Oh... wow... looks like it could be much worse than several hurricanes and a tsunami... or even global warming." Then she said "Good grief!" Then she started babbling on and on and not making much sense, I think at one point she said she was very sorry for all the bad things she did while growing up, calling her little brother names and stuff.

[Styxx]

Yeah well all I have to say is I want to be where she is when it happens. Anyone for building more spacestations? Dave ... what are you doing, Dave? :D

[SeanHannifin]

Yikes, that would really stink! :eek: However I must say that's some nice computer animation and I really enjoyed the music!

[DPDAN]

As usual, Styxx has the best line!!!

me :D

How about the real thing?

"OSLO, Norway, June 9 (UPI) -- A large meteorite struck in northern Norway this week, landing with an impact an astronomer compared to the atomic bomb used at Hiroshima."

It might be a really good idea if we spent some of our billions on detection and prevention of such events, rather than... other things.

This is a rather nice try to show what may happen, yet not exactly my idea of how it would occur.

First, the meteorite would strike the earth as shown in that video. Yet, assuming that it has a lower density, would bob ontop of the Earth. If it has a high enough density, it would sink into the earth. If the density is super massive (I'm talking like solid lead or something of the sort), then we have to worry about a giant wave of debris. Yet the slow sinking of the meteorite would seem to be the most logical.

Upon it sinking, the earth has to relieve the pressure. Faultlines would expand and new ones would form (good bye california...). The sudden expansion of faultlines would cause sea water to be dumped in, causing a quick evaporation of the water. The atmosphere opposite the fireball on the earth would then become heavily saturated, cooling down and hardening the new crust of the earth.

Meanwhile, the fireball would rain debris in the form of town sized boulders. Some with a higher trajectory would be sent into space. Others would be flung hudnreds of miles, thus causing several more holes through the crust, assuming strikes in the oceanic sections. This would relieve more pressure, the crust would fill in with water and rebuild itself.

If we are lucky, the clouds of water will cool off enough and help cool down the heatwave that would be traveling around the Earth. We would suffer massive rains and mass heat at the same time. Yet it might take several passes of the wave to subdue it. The water would clear the atmosphere and help break down the soil for plantlife to regrow. The bacteria would break down the rock and allow remaining seeds a place for home. Yet all other animal life would have perished. If everything were to go wrong, then at least some of the debris would be carrying bacteria to either revitalize the Earth in the future or to populate other planets.

Once the ground is cool, the mantle of the earth would cool off after relieving the pressure. This cooling would start to leave gaps underneath the crust, thus causing collapses. Yet, after the entire process is done, our Earth would turn out larger, dryer (the water would still be here, just a lower amount to surface area), and darker. Life would then, if given the chance to, start to regrow. Yet there is no telling if there would be another human race to invent orchestral libraries and sell them to others for relatively cheap prices. All that can be certain is that, assuming that evolution is true, the bacteria and plantlife will evolve into an entirely new world capable of existing in a much smoother (less large meteors, one of them just crashed) or rougher (sun exploding...) era.

Yes, I have thought this over quite a few times. I have also considered animating it, I just suck at creating characters in my software. I can do explosions and cosmic scenes, plus special effects with particles and camera actions, but I suck at characters and plants...

Stephen Hawking must have watched that video also. He says we better pack up and get off this planet.

C_J_Pro. All nice theories. However, I can't help imagining a meteor that large would "push" the Earth out of orbit and off its axis as the first consequence. Like a cue ball hitting the eight ball or like a bocce ball game. And or the Earth may just split in two, thirds, fourths, or eigth notes, given the right speed, trajectory, and force. Regardless, this meteor theory just proves one certainty. You can do nothing.

[C J Pro]

The meteor would throw us into an alternate orbit, but chances are low of us being tossed into the sun. Yet, it would heighten the chance of a collision with Venus or Mars...

Also, a meteor going at a speed to blow the earth apart would be impossible. First off, The crust would fold in on itself, building up pressure in the mantle and core. The crust would crack along the rear sides to relieve the pressure. If it is powerful enough, the meteor would go through the planet, but would leave most of the planet behind. Yet, this is very unlikely. It is more likely that the meteor would slowly melt into our own mantle and help reform the curved shape that we know of today. Essentially, our planet can recover itself from almost anything. It cannot survive novas, supernovas, hypernovas, black holes, the "Big Collapse", man, collisions with larger objects, etc. Yet those have a really low chance of occuring...

HAWKING WARNS: HUMANS MUST GO INTO SPACE TO SURVIVE :eek:

According to a report in MyWay.com (http://apnews.myway.com/article/20060613/D8I7ADB81.html),

"HONG KONG (AP) - The survival of the human race depends on its ability to find new homes elsewhere in the universe because there's an increasing risk that a disaster will destroy the Earth, world-renowned scientist Stephen Hawking said Tuesday.


The British astrophysicist told a news conference in Hong Kong that humans could have a permanent base on the moon in 20 years and a colony on Mars in the next 40 years.


"We won't find anywhere as nice as Earth unless we go to another star system," added Hawking, who arrived to a rock star's welcome Monday. Tickets for his lecture planned for Wednesday were sold out.
He added that if humans can avoid killing themselves in the next 100 years, they should have space settlements that can continue without support from Earth.


"It is important for the human race to spread out into space for the survival of the species," Hawking said. "Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers we have not yet thought of."


The 64-year-old scientist - author of the global best seller "A Brief History of Time" - is wheelchair-bound and communicates with the help of a computer because he suffers from a neurological disorder called amyotrophic lateral sclerosis, or ALS."

A big meteor don't scare me.......Bring it on!!!

Also the video ignores the power of prayer...... Let's start praying now!:eek:

[Cataclysm]

... It does look like Death Star a bit.

[C J Pro]

... It does look like Death Star a bit.

Sith Lord: You did what to my battlestar?

Also, I would find it rather amusing if we see a large astroid like that one coming in at a high speed towards Earth. So we escape to Mars for safety. We then watch the impact from Mars, just to find out it missed Earth and swings around towards Mars...that would be the worst year ever.

[SeanHannifin]

What if the moon falls down on top of us?! :eek: :(

[Cataclysm]

What if the moon falls down on top of us?! :eek: :(

Well, that limits down the numbers of places we can escape to if our earth does gets destroyed...

[C J Pro]

Don't worry, last I checked the moon was slowly getting further away from us. This is making days longer for us though...

A Meteoroid Hits the Moon :eek:

Last month, astronomers watched a meteoroid blast a hole in the lunar Sea of Clouds. Here is a link to their video (http://science.nasa.gov/headlines/y2006/13jun_lunarsporadic.htm?list62151):
http://science.nasa.gov/headlines/y2006/13jun_lunarsporadic.htm?list62151


June 13, 2006: There's a new crater on the Moon. It's about 14 meters wide, 3 meters deep and precisely one month, eleven days old.

NASA astronomers watched it form: "On May 2, 2006, a meteoroid hit the Moon's Sea of Clouds (Mare Nubium) with 17 billion joules of kinetic energy...The impact created a bright fireball which we video-recorded using a 10-inch telescope."

[etLux]

What if the moon falls down on top of us?! :eek: :(
I worry about that every night.

No one's checked the rope that holds it up there in years.

Not to worry... as we all should have learned from Star Trek episode #58 (The Paradise Syndrome), we need only for Scotty to apply the Enterprise's tractor beam to divert the asteroid safely off its collision course.

[EricWatkins]

Actually, I'm waiting for this little doo-dad to come around. http://www.space.com/businesstechnology/technology/space_elevator_020327-1.html

[C J Pro]

Yes, a giant elevator. Now, we just need a large white flag to put on it to tell people on the otherside of the galaxy our message.

[Shazbot]

Wow. Creepy. And what's particularly disturbing is that although I can't understand a word the narrator is saying, she sounds really excited about it! :p
