But it does emphasize that nobody has answered the challenge.
The absurdity of your challenge has been discussed at length. You don't get to beg the question that your demands are reasonable.
Even if you believe the spacesuits and sublimators work as claimed, you should want the demonstration I describe so that you can KNOW they work as claimed.
I don't need the test you propose in order to know that they work. You don't get to beg the question that your demands are reasonable.
I'm puzzled by everyone's reluctance to demand a demo.
And that should tell you something. If you're the only one who seems to want something, you shouldn't presume it to be something that's objectively necessary. Further, you have ignored the production of everything else you said didn't exist. So your critics can be excused for not taking your demand at face value. You offer them no assurance this is really what would convince you. You instead convey the impression that no amount or kind of evidence would change your mind.
Is believing you're right so much better than knowing the truth?
You offer no truth. By your own admission you offer only speculation, and you are unable to reconcile that speculation with the evidentiary record except by more speculation. Since you offer no reason to reject the null hypothesis, it remains the presumption.
