Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds. The Copernican model displaced the geocentric model of Ptolemy that had prevailed for centuries, which had placed Earth at the center of the Universe. Copernican heliocentrism is often regarded[by whom?] as the launching point to modern astronomy and the Scientific Revolution.
Heliocentric model from Nicolaus Copernicus' De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres)
Although he had circulated an outline of his own heliocentric theory to colleagues sometime before 1514, he did not decide to publish it until he was urged to do so late in his life by his pupil Rheticus. Copernicus's challenge was to present a practical alternative to the Ptolemaic model by more elegantly and accurately determining the length of a solar year while preserving the metaphysical implications of a mathematically ordered cosmos. Thus, his heliocentric model retained several of the Ptolemaic elements, causing inaccuracies such as the planets' circular orbits, epicycles, and uniform speeds,[1] while at the same time introducing such innovative ideas as:-
The Earth is one of several planets revolving around a stationary sun in a determined order.
The Earth has three motions: daily rotation, annual revolution, and annual tilting of its axis.
Retrograde motion of the planets is explained by the Earth's motion.
The distance from the Earth to the Sun is small compared to the distance from the Sun to the stars.

Answer:
1 - 9/11 was the terrorist attack that took place at the World Trade Center, the Pentagon, and another unknown target. Personally, I believe that the terrorist attack was a tragic loss of life and shows how nations, such as the United States, need to rise and unite against terrorist threats.
2 - I believe that pain and destruction on Earth created by humans has a lot of sources. Whether it is political, for money, or due to the corrupt mind of a human being. It may be for persecution against a race, ethnicity, etc, it may be for control of land, or it could be for religious purposes.
3 - The 9/11 attacks occured due to 19 Islamic terrorists. These terrorists were funded by a man known as Osama Bin Laden. Osama "declared war" against the US in 1998 where he called for the murder of American civilians. The attacks may have occured to incite the United States into a war against the Islamic regimes in the Middle East. It could have also been to deter the United States away from the Middle East and Israel.
