Understanding the argument -
A theory is either true or false.
Galeleo's observations of Jupiter's satellites showed that the Ptolemaic theory of motion is false.
Ptolemaic theory is inconsistent with Copernican theory.
So, Galeleo's observations of Jupiter's satellites showed the truth of Copernican theory.
The argument, though crystal clear, if read in a hurry, can be bewildering or confusing.![Image]()
So read carefully and connect the sentences. The argument is based on a key assumption which is one of the theories has to be true, and both can't be false at the same time. Because if both are false at the same time, then in this case, we can't say with 100% confidence that falsifying Ptolemaic's theory automatically means that Copernican theory is true.
There could be another assumption as well, which is that there can be 20 other theories
