What is the definition of Settled Experiments?

"Settled experiments" is like the ultimate science-y, yet slightly silly, term for those experiments that were conducted in a place where nobody was allowed to ask questions or make changes mid-project. Imagine if you were trying to figure out how to make a peanut butter and jelly sandwich but your sandwich maker had a mind of its own, refusing to let you tweak the ingredients. That's your settled experiments - the tried-and-true, but possibly outdated methods that have been perfected but not necessarily updated for the modern age of scientific inquiry.

Here's an unsettling example sentence: "After months of settled experiments on the anti-gravity powder, we decided to settle down with our newfound ability to defy gravity, but we ended up accidentally setting the kitchen on fire."
