Sometimes new information results in minor changes to a theory. But sometimes new information results in a theory being discarde
seraphim [82]

The Ptolemy's theory of the solar system was disproved by the discovery of the new information. The Ptolemy's theory stated that the Earth is at the center of the solar system and all the planets, suns and stars orbited around it while the Earth stayed completely stationary. However, this theory was proven to be false as the sun-centeric model of the solar system better explained various phenomenon, such as the particular movement of the planets.

Hence, the correct answer is 'Ptolemy's theory of the solar system'.
