1. Which statement regarding scientific models is true?
(a) Models that do not make new predictions are wrong.
(b) There can only be one model that explains a set of observations.
(c) We design experiments to prove that a given model is correct.
(d) Any model that cannot explain the observations is useless and should be discarded.
(e) We prove a model is right when we observe the predictions it makes.
The geocentric model, in all of its complexity, survived scientific scrutiny for almost 1,400 years. However, in modern
astronomy, scientists seek to explain the natural and physical world we live in as simply as possible. The complexity of
Ptolemy's model was an indicator that his theory was inherently flawed. Why, then, was the geocentric model the leading
theory for such a long time, even though the heliocentric model more simply explained the observed motions and
brightness of the planets?
Check all that apply.
☐ The geocentric model conformed to both the philosophical and religious doctrines of the time.
☐ The heliocentric model did not make noticeably better predictions than the geocentric model.
From Earth, all heavenly bodies appeared to circle around a stationary Earth.
The complexity of the geocentric model was appealing to most ancient astronomers.
Ancient astronomers did not observe stellar parallax, which would have provided evidence in favor of the heliocentric model.
Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion.
Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU.
Does this make physical sense? Explain why or why not.

Brahe collected astronomical observations, which were passed into Kepler, on his death. Among the significant contributions of Brahe: 1. His observations on the planetary motion of Mars were used by later astronomers, including Kepler to construct the present model of the solar system. 2. In 1572, he observed supernova as a star that appeared suddenly, became visible for 18 months before it faded from view. Nowadays, supernova is called an exploding star. 3. In 1577, he observed a comet by measuring its parallax. His claim contradicted the idea of Aristotle that comets are "gases burning in the atmosphere." By measuring the parallax for the comet, he was able to show that the comet was further away than the Moon. 4. His findings that stars do not have parallax, he concluded that either: (a). the earth was motionless at the center of the universe; or (b). the stars were so far away that their parallax…arrow_forward
