Plastic Bug
You have no business asking.
Thanks for yor post - though I am not sure about your statement - please feel free to illustrate where in the forum rules you are not allowed to ask questions if you don't know an answer, you could help me there. I think john_tullamarine's answer does not agree there.
Final 3 - thanks for you exmaples of hypothetical learning - I quite agree that there does not
have to be a concrete conclusion (but also, I hope you will agree, there sometimes is a conclusion).
Even though we know that there is no empirical data avilable to answer the question to a high degree of confidence, Mach 4.0 was asking for help to
1. Find some of that data (obviously not empirical, but from public domain reserach).
2. Get guidance on the process of investigating the question using the data.
Thanks.
