Earth was the center of the universe.
Earth was the center of the universe.

The universe was the only object they could see.
The universe was the only object they could see.

The motion of the planets was uniform and circular.
The motion of the planets was uniform and circular.

Earth was not moving.
Earth was not moving.

The motion of the planets was uniform and circular.

The idea that was most contested by some philosophers in the geocentric model of the solar system was that Earth was not moving.

The correct answer is: "The motion of the planets was uniform and circular." This idea of the geocentric model was most contested by some philosophers.

To arrive at this answer, one can analyze each statement and determine which one was more likely to be questioned or disagreed upon by philosophers.

1. Earth was the center of the universe: While this idea was fundamental to the geocentric model and eventually proven incorrect, it was widely accepted during the time and did not face substantial contestation.

2. The universe was the only object they could see: This statement, although partially true, does not directly challenge any specific aspect of the geocentric model. Therefore, it is less likely to be the most contested idea.

3. The motion of the planets was uniform and circular: This is the most contested idea among the options. Some philosophers, notably including Tycho Brahe and Johannes Kepler, questioned the assumption of uniform and circular motion. They proposed alternative models, such as elliptical orbits, which led to the eventual acceptance of the heliocentric model.

4. Earth was not moving: This statement aligns with the geocentric model and was not significantly challenged by philosophers.

Based on this analysis, we can conclude that the idea most contested by some philosophers was that the motion of the planets was uniform and circular.
