1. Asteroids
There have been many mass extinctions throughout the history of the Earth. Probably the most famous is the extinction that finally saw the end of the dinosaurs reign on the Earth, 65 million years ago. It wasn't just the dinosaurs that died out in this extinction. Whatever caused the death of the dinosaurs also caused the death of around 70% of all of the species on the Earth. Although the dinosaurs had been in a period of decline, it is thought that some sort of catastrophic event prevented their recovery. There are many theories about why the dinosaurs finally became extinct, some of which are more than a little outlandish. According to one theory, the impact of asteroid or comet caused massive destruction of the environment, leading to the extinction of the dinosaurs. Evidence to support this theory includes the discovery of a buried impact crater (conjectured to be the result of a large comet striking the earth) that is 124 miles in diameter in the Yucatan Peninsula of Mexico, and a recently recovered deep-sea core contains convincing new evidence of an asteroid impact 65 million years ago, when dinosaurs went extinct.
This deep-sea core provides convincing support to the hypothesis that an asteroid collision devastated terrestrial and marine environments worldwide. It also shows a record of flourishing marine life before the event, followed by mass extinction and then evolution of new species and slow recovery of surviving life forms after the event. The spray of debris was blown from the edge of the crater. The debris has been found over large regions of North America. Comet enriched material from the impact's fiery explosion was spread all over the world. With radiometric dating, scientists have used the decay rates of certain atoms to date the crater, spray of debris, and fireball layer. Using similar techniques to date the dramatic changes in the record of microscopic fossils, they have found that the impact and the dinosaur extinction occurred nearly simultaneously.
The hotel will also have a science lab to research asteroids, but this lab will be hidden from all guests. The scientists will research asteroids to get additional information on them near the asteroid belt. ... Power Source On the Asteroid Hotel the power will be supplied by big solar panels, which would supply all our energy. ... Air in Space The Asteroid Hotel has a source of oxygen for all guests and crew to breathe and removes carbon dioxide, which the crew and guests exhale. ... Exercising is very important when on the Asteroid Hotel, it is for your own health to do exercise. ...
Their theories should not have been published without months, maybe years of lose observation of the asteroid and its orbit. A closer investigation of the asteroid showed that there was no chance at all that the asteroid would collide with the earth. If the astronomers had waited to further investigate their "discovery," they would have known that there were pictures of the asteroid taken in 1990, pictures which provided hard evidence that the asteroid would in fact not collide with the earth. ... It seemed my brother did not really care about the possible threat of an asteroid colliding w...

Eventually, one of these asteroids will make contact with the land on earth. It is possible that man could deal with an asteroid. ... Each comet or asteroid must be dealt with in an individualistic manner. ... The asteroid was not large and would have not done much damage, if it had hit the earth. ... It is obvious that a giant crater or asteroid hit the earth, and wiped out the dinosaurs. ...
If Asteroid 2002 EM7 would have pierced the atmosphere, the seventy meter long asteroid could have disintegrated and unleashed the energy of a four megaton nuclear bomb. ... The asteroid, called 1999 AN10, will be closely watched over the years (The Looming Threat 1). It is highly unlikely, if not impossible, for an asteroid to completely destroy the planet Earth. The Earth is many times larger than the biggest asteroid and is capable of absorbing huge shocks. ... In 1908, an asteroid rocked the grounds of the Siberian forest. ...
Not everything ran as smooth as planned, as the pictures taken by the space craft became blurry as it approached the asteroid. ... At that point it was looking very doubtful that the craft would be able to get near the asteroid. ... They did that in the very nick of time but they now had to worry about colliding Deep Space 1" with the asteroid itself. ... As a consolation prize, Deep Space 1 took a parting shot of the asteroid as it was heading away from it. ... Comet Borrelly Immediately after the flyby of asteroid Braille, Deep Space 1 was given a new objective. ...
