Why didn't the dinosaurs get on spaceships before the meteor hit earth?

Because they overslept and missed their flight.

Oh boy, there are about three relavant answers to that question.  First one is that a large meteor hit near Cancun Mexico, which sent wave after wave of dust into the atmosphere blocking out most of the suns rays, and killing off vegitation, causing herbavors to starve, which left the carnivores with nothing to eat.  Another theory is that they mearly evolved and were replaced with more capable species, which replaced them.  Yet another is that a very intense volcanic eruption occured (probably something like yellowstone) which did the same as the meteor would have.  It would've blocked out the sun, cooled the planet, and killed off most of the vegitation.

You are nuts!. . .Because the dinosaurs died doesn't mean God failed. . .it means the dinos are in Heaven!  (Except the ones who didn't accept Jesus Christ as their Lord and Savior, and the ones who were gay dinosaurs, or voted Democrat.)

As a late development of the dinosaurs Archeopteryx would have come extinct at the Cretaceous-tertiary boundary about\n66 million years ago (when all dinasaurs became extinct)the cause was a large asteroid that hit he earth off Yucatan in Mexico causing cataclysmic environmental changes.\n\nhttp://en.wikipedia.org/wiki/Archaeopteryx

Holy cow-thats a Master's thesis project at least!  Ok, there are lots of theories out there concerning a cataclymic hit-and since both she and the people she is comparing also believe in the asteroid theory, we have to just think of all the things that could happen, reasonably:\nThe ashes from the volcanoes could block out the sun so drastically that it became too cold for the dinosaurs to live\nThe ashes blocked the sun out sufficiently to kill the major plant life, so the herbivorous dinos starved, and then the carnivores starved.\nThe volcanoes spewed out sufficient CO2 that the dinos suffocated\nThe volcanoes spewed out toxic gas that poisoned the dinos.\nThe volcanoes subtly changed the climate so that over thousands or hundreds of thousands of year, other lifeforms, such as mammals, birds, and the surviving reptiles, gains a major advantage and caused the dino extinction.\nAbout the meteor:  Either you could hypothesize that the volcanoes erupted spontaneously, and it had nothing to do with meteors, or that the meteors by themselves weren't a killing force but disrupted the crust of the Earth sufficient to open up volcanoes all over the Earth, or that the meteor alone killed most of the dinosaurs, and the resulting volcanoes killed off the rest.\nI didnt mention the effects of tsunamis and earthquakes caused by the volcanoes because that wouldnt reasonably be enough to kill off all the dinos.\nHope those ideas help-good luck.

You need help so I am going to help you alot right here first I am sorry but the person that put the dates on the dinsouar created the 6th day needs to read his text books again and look at his history ok. With that said I going to answer your question and show you all the time line\n\n251 MYA-The Mesozoic Era starts, and the Triassic Period Begins. \n230 MYA- The First Dinosaurs Appear \n200 MYA- The Jurassic Period begins \n145.5 MYA- The Cretaceous Period Begins. \nc. 65.6 MYA- An Asteroid hits the Earth. The Dinosaurs survive, but begin to die out. \n65.5 MYA (DOOMSDAY)- The Earth is hit with a sudden climate change (possibly another Asteroid), This time, the Dinosaurs will NOT survive! \nc. 64 MYA- the Cenozoic era Begins. \nc. 64 - 49 MYA- for the first few million years, The entire Earth is ruled by one Creature; up to 2ft+ tall, and prayed on horses... The Birds: the decendants of the Dinosaurs\nand there was several Ice Ages after that.

The biggest dinosaur currently known is generally conceded to be Argentinosaurus, a huge sauropod (brontosaur-type) from the late Cretaceous of South America.  Extrapolation from the size of the fossilized bones found indicates that Argentinosaurus was up to 120 feet long and weighed in the neighbourhood of 100 tons.  The maximum weight estimate for a huge dinosaur like Tyrannosaurus was 8 tons, so Argentinosaurus was massive even for a dinosaur.\n\nAs to how some animals survived, while others did not is one of the big, big mysteries of the KT extinction event.  Why did pterosaurs all go extinct, but birds survive?  Why did ammonites and belemnites all go extinct, but sharks and nautilus survive?  Why did giant marine reptiles like mosasaurs and icthyosaurs go extinct, while crocodiles and snakes survived?  Some of those are hard to explain if an asteroid impact was the sole reason for the extinctions.  The general consensus seems to be that there were a large number of factors such as continental shifts creating faunal interchange between long isolated populations, which could spread disease among dinosaurs.  The continental shifts would also have altered ocean currents, changing environments and climate, and altering existing eco-systems (especially some of the rich shallow seas that existed at the time).  Adaptive radiation of flowering plants (Angiosperms) in the late Cretaceous may have caused stress on those animals that were dependent on the competing Gymnosperm plants.  Co-evolution of many insects in response to the radiation of Angiosperms may have somehow favoured the survival of the birds over the pterosaurs.  \n\nThen when the asteroid impact occurred, it was the straw that broke the camel's back for many of these species that were under intense pressure, but other species were able to survive.

Great question.\n\nThe reason that they don't collide is that the moon is moving to fast.\n\nCheck this out- when the space shuttle is up in space it is only about a 100-150 miles up there. Why doesn't it just fall out of the sky and crash into the planet? \n\nWell the answer to why things don't fall out the sky is because they are in orbit- duh-. The space shuttle is not only up in space it is also moving sideways at a tremedous speed. The shuttle IS falling out of the sky, but the reason it doesn't ever hit the ground is all that sideways motion. Everytime it starts falling, the earth has moved out of the way ( sideways- remember) so it changes direction and starts to fall again, well guess what the earth has moved out of the way again. This keeps repeating and repeating. in essence anything in orbit- satelites, moons, and space shuttles are always falling but they never seem to get there. That is why the moon never hits the earth. It's important to remember that just because you are in space does not mean gravity is not pullin you down. I assure you if the shuttle was somehow able to suddenly stop it would fall out the sky like a rock. The reason the people in the space shuttle are floating is because they are falling and not because they are in space.\n\nI just have to add a little more to this statement- You know that in freefall ( you jumped out of a airplane ) you can't feel gravity and there is no up or down or sideways. The same thing with being in orbit since you are always falling you can't feel gravity either. One other thing the people that wrote first on this question really need to double check their facts. The Perfect distance and gravity cancelling out stuff is wrong. The moon could and used to be much closer to earth. It also went around earth much faster, but because of tidal action the moon has slowed down and gone into a farther out orbit. The moon even today is leaving the earth at about three inches a year. It is slowing down and so is our day- our day is getting longer because of the moon

The egg.  Dinosaurs were laying eggs far before chickens had evolved, so the egg had to've come first.  :)

The Ionosphere helps refract radio waves so they can travel very long distances, more than line of sight as they bounce around inside it.\n\nPilots fly in the troposhere because it is dense (density affects LIFT). Jets actaully fly right at the top on the troposhere to avoid turbulence.\n\nHmm, as for the mesosphere, not that much of this is known. it's higher than aircraft altitude and lower than spacecraft altitude so not much travels in it. It's the first line of defence for any meteors that come into the earth's path tho so I guess that's quite important.

There was a mysterious explosion.  The explosion was extreamly powerful (on the scale of atomic bombs I believe), flatting trees all around.  But it wasnt for a number of years that people were able to get up there and try find out what happened.\n\nIt possible could have been a meteor explosion right before it hit the ground, but there is no other evidence to support this.  I dont think we really know what happened, but the meteor idea is pretty likely I think.

since UFO simply means Unidentified Flying Object, anything you see zipping about in the sky that you can't identidy is a UFO... so yeah, you sorta have to believe in them.  ;)  \n\nas for creatures from another planet finding us, the possibilities of that are slim, due to the vastness of the universe.  travel at or above the speed of light is impossible, as that's when you get complete molecular and atomic disintigration.  the only way life can travel distances is if energic beings exist, or if it's in some primitive seed state, dormant inside some meteor, but that's not all that likely, especially since when simple protein molecules impact at those high speeds known to meteors, they change..  forming amino acids.  this is cool, as such can help form the building blocks of life, but i cannot imagine that such would actually spawn life, but hey, life is a product of environment, so if a species evolved to spread as such, then so be it.\n\nback to sentient beings finding us, let's say they mastered interstellar travel..  at speeds that don't cause their matter to break up, they could travel, but their ships would have to be of some sort of colony-type, so that the decendents of those who set out would be the ones that eventually "got there"...  and then our planet would be little more than a pile of resources they'd just end up taking, than some opportunity for some cool star-trekkish interstellar alliance.  ;)

Because the earth orbits the sun in the same direction as its daily spin, we are on the "trailing" side of the globe before midnight. This means that meteoroids must "catch up" to us in order to burn up in our atmosphere, and will be slower (and so fainter) when they do. After midnight of course, the situation is reversed... The result is that you usually see many more meteors near dawn than near dusk!

Obviously, it's not an actual explosion, but the effects are very large.  Let's take the one that's supposed to have killed off the dinosaurs.  The meteorite was very large - I don't have the scientific estimates in front of me, but at least a kilometer in diameter, probably more.  Now this thing is big and moving at a very high velocity; it has lots of kinetic energy.  When it hits the earth, the meterite stops moving, but according to the Law of Conservation of Energy, the energy can't just disappear.  Instead, it has to be changed into other forms such as sound, heat, and vibration.\n \n Also, there's Newton's law that says for every action there is an equal and opposite reaction.  If you throw a ball at the ground it will bounce back, but if the ball has no elasticity and can't bounce, then the ground itself (part of it, dust etc.) will bounce back instead.  That's what happened when the meteorite hit earth.  Only, of course, it was a lot bigger than a ball, and the crater it created was between 180 and 300 km across.  It's in the Yucatán Peninsula in Mexico, if you're interested.

no because by any logic those dinosaur couples would not only have crowded everyone else off the ark, but would also have sunk it. since the bible never mentions that the ark sunk due to overweight brontosaurii, dinosaurs are blasphemy.\n\nyou do know that we're both going to hell for being involved with this question? if you bring the sunscreen, i'll bring the shades and Jimmy Buffet tape.

"...Small stones to a few millimeters in size are slowed down so much by the atmosphere that they end up drifting slowly to the ground. \n\nPieces of space rock of a few millimeters to a few centimeters burn up completely in the atmosphere of the Earth before they can reach the ground, and can be seen at night as falling stars. If it is sufficiently dark and clear outside, then you can see a few falling stars every night. \n\nIf the rock is bigger, then part of it can survive the trip through the atmosphere and reach the ground as a meteorite. If the stone weighs less than a few tons, then it doesn't fall very fast anymore in the end, and it makes a small dent in the ground.
