Question

Sort the following hypothetical discoveries into the appropriate bins as follows:consistent with theory: the statement describes a discovery that we could reasonably expect to find if the nebular theory is correct.not consistent with theory: the statement describes a discovery that would force us to modify or discard the nebular theory.

Answer 1

Here are the three observable facts that are explained by the nebular theory:
1) Planets all rotate in the same direction
2) Planets all orbit in within 6 degrees of a common plane
3) Planets within the orbit of the Asterioid Belt (terrestrial planets) are rocky while those outside it are gaseous. 

Here are the missing statements and its appropriate labels:

all 6 of stars terrestrial planets have a moon as large as earth's moon - NOT CONSISTENT WITH THE THEORY

a star is surrounded by a disk of gas but has no planets - CONSISTENT WITH THE THEORY

a star has 20 planets - CONSISTENT WITH THE THEORY

a stars 5 terrestrial planets orbit in the opposite direction of its 3 jovian planets - NOT CONSISTENT WITH THE THEORY

beyond its jovian planets, a star has two ice-rich objects as large as mars - CONSISTENT WITH THE THEORY

of a stars 5 terrestrial planets, 1 has a moon as large as earth's moon - CONSISTENT WITH THE THEORY

a stars 4 jovian planets formed in its inner solar system and its 4 terrestrial planets formed farther out - NOT CONSISTENT WITH THE THEORY

a star has 9 planets, but none orbit in close to the same plane - NOT CONSISTENT WITH THE THEORY
