Ptolemy's theory of geocentrism, which placed Earth at the center of the universe, was helpful at the time as it provided a simple model to predict planetary positions. It helped early astronomers make sense of the movements of planets in the sky. However, it was eventually replaced by the heliocentric model proposed by Copernicus.
Galileo and Copernicus were two of the scientists to disprove Ptolemy's geocentric theory of the universe. The Ptolemaic theory stated that the center was earth.
Shortly before Copernicus died he figured that the Earth was notthecenter of things, but the Sun was. This theory is still used today. He worked out this this theory from detailed observations of the orbit of Mars.
Earth was the center of the universe
Wallace's contribution was almost similar to what Charles Darwin's theory of evolution is. Is that helpful?
his map was made in 1482. and used by cristpher colombus.

The theory of common decent was one of the most helpful ideas in the formulation of the evolution of species. This theory acknowledges that to share common denominators there was a shared ancestor.
you are a ideot dumb one
Might be helpful if we new the theory....
Ptolemy thought the earth was the center of the solar system (Otherwise known as the Geocentric theory) and Copernicus's idea was that the sun was at the center of the solar system (Heliocentric theroy).

A rejected hypothesis could be helpful to a scientist because it helps them create a theory by process of elimination.

Yes, it would be! And No it wouldn't at the same time!
