Question: if you had a question to do with science that you wanted to know the answer to and no one else has ever found the answer to your question how long would it take you to find the answer or to do the experiment?
Yes, that’s exactly what we all do all day, work on questions that no one else has solved yet. Of course, there are usually a lot of people working on that same question, and by talking and working with them you can make progress.
In my experience, so far it’s taking me between two weeks (for the shortest) and fifteen years (for the longest). Scientists are very stubborn!
Precisely as Michel said, most of my work involves working on questions that no one else has managed to figure out yet. In terms of experiment times, my reaction times vary from 30 minutes to about 5 days, but solving an overall problem may take longer than that: I’ve certainly been working on at least one for two years and counting!
