Description : How did the early scientists figure out all of these scientific facts (gravity, planetary motion, etc.) without the technology we have today, and how can we trust them?
Last Answer : answer:None of these discoveries were made in a vacuum. Oftentimes, new discoveries were made as replacements or responses to old lines of thinking that simply did not work or weren't true. And more ... not, people didn't trust the scientists at the time, but history has vindicated most of them.
