Question

Which of the following is an example of an outdated theory based on the consensus of the scientific community

A. big bang
B. geocentric solar system
C. heliocentric theory
D. plate tectonics

Answer 1

Option (B)

Explanation:

In the initial time, the geocentric model of the solar system was initiated that described that the solar system is comprised of the sun, planets, stars and other rocky planets, in which the earth was considered to be at the center and all the rest of the celestial bodies orbit moves around it.

This model was not able to explain the changes that occurred in the appearance of the other planets that were present between earth and the Sun.

Thus, after much of the researches had been done on the solar system, the new data were obtained and cleared the idea that the sun is at the center of the solar system, not the earth. So, this model was considered to be an outdated theory.

Hence, the correct answer is option (B).

Answer 2

The correct option is Geocentric solar system.

Explanation:

The correct option is Geocentric solar system.

According to this system, the Earth is considered to be the center of the solar system. The Moon, the planets, the Sun, and the stars all rotate around the Earth (which stays still), with uniform circular motion. They compose the heavens, which are considered to be ethereal and unchanging. Ptolemy proposed his refined geocentric model. In the Ptolemaic universe, a planet moves in a small circle called an epicycle, and the center of the epicycle moves along a larger circle around the Earth.It was accepted until the 16th century.
