Round Earth Theory
Yes , the idea of the most renowned of the theory of the earth is round, it is believed by most people until now . Initially, before the advent of this theory , the most widely believed theory is the Flat Earth Theory which will be discussed below . As we all know about this theory , this theory says that the earth is round like a ball shape ( though not completely round ) .
The person most associated with the idea of this theory is Phytagoras confirming the theory of Plato ( Greek ancient philosopher ) that the earth is round. But that probably most of us know is about Columbus’s voyage (to be discussed in the Flat Earth Theory below )
Flat Earth Theory
Never believed to 17th century , this theory says that the Earth is flat like a disc shape (disk ) . This theory is the mathematical believed to Greek and European ones believer earth is round. This misconception has also been trusted by Christopher Columbus ( Discoverer Americas ) , to break her own beliefs voyage . Therefore sebagi voyages also called ‘ Myth of the Flat Earth’.
In 1956 , a Flat Earth Society assembly that supports this theory is made. Even in 1980 , although there has been evidence that says that the earth is shaped like a ball, one of the people of this grouping named Charles Johnson publishes that it believed the earth was flat . This he got from looking at the flat surface of the lake water , it says if the earth is round so at least there will be a curve ( curvature ) in a body of water .
Hollow Earth Theory
This theory was triggered by John Symmes , a former U.S. Army captain in the war of 1812 . It believer that the world has a thick shell of 800 miles, with an opening at both poles and the number of layers in the range of cengkungan – cengkungan . Cengkungan this is where we and the animals live .

If you meet these people , especially in a party or banquet together , you may need to rethink where parking offenses from your life.
Counter Earth Theory
There is no expiration on the existence of imagination ” Other Earth ” out there , Counter Earth Theory is one theory that says about this. It says that there is a parallel earth in this universe , we never see this because it is the exact opposite orbit our planet ‘s orbit and on the other side of the sun. This scenario is also available in the 2011 film , Another Earth .
If we think about the facts and the evidence that has been collected and have been there before, then we can say that this theory very unlikely. This theory in old age might still be acceptable due to the lack of technology to monitor, or endorsement mefoto go outer space. But with the advent of technology , we can prove that there is nothing on the other side of the earth orbits the sun .
