The Threats We Face
Four years ago on August 24th 2003, an important discovery was made by a group of researchers at MIT’s Lincoln Laboratory. This discovery would make scientist raise the question about what the future may hold for our planet Earth. This was the discovery if a meteorite which was named QQ47 and even more important was the discovery that this Object was in a collision trajectory with Earth scheduled to impact some time in 2014. This grim discovery painted the first real threat of earth being completely by a meteorite.
Even though very little is known about QQ47 it has a very real chance of striking Earth. Although some scientist like Donald Yeomans of NASA points out this may threat may eventually go away once scientist learn more about this asteroid, Just like it happened with a similar threat back in 2002 with meteorite NT7.
Near Earth collision have the potential to completely wipe out humans from the Earth upon impact. Once this Near Earth Object as they are called, entered the earth surface there would be very little that the atmosphere would disintegrate only if it’s a small NEO less than the size of 40m if its bigger it would through the entire planet into an Impact winter. It would take an object about the size of a garage to destroy an entire city. One that is bigger would completely annihilate the planet. The impact would immediately kill every living thing in a 500 mile range due to the shockwave that would result. This shockwave would also raise incredibly high waves that would travel several miles in inland causing more destruction. Earthquakes and volcanoes would more than likely become active all around the world. Also the mount of material that this impact would raise into the atmosphere would be capable of blocking the sun for month’s even years. Water sources would be contaminated and other food sources would eventually disappear. This is one of the theories on the extinction of the dinosaurs...
