Galileo disproved Ptolemy's theory about the moon's surface being smooth and polished; instead, he found it to be cratered and uneven.
- The statement about Galileo that is not true is: d. He was able to prove that Ptolemy's theory that the moon had a smooth, polished surface was true.
- In fact, Galileo's observations refuted this claim by revealing the uneven, cratered surface of the moon.
- He did indeed become a professor of mathematics at a young age, developed new scientific instruments, designed a powerful telescope, and after facing the Inquisition, was forced to recant his support for the heliocentric model, which stated that the Earth revolves around the sun.
- However, his work could not be suppressed indefinitely and was eventually acknowledged.
