Basic principle of logic: Big claims require big proof. For example, if I were to say "I'm from another time, and came here in my time machine" then it would logical for you to reply "Wow, that's quite the claim, would you be so kind as to show me that time machine of yours, and perhaps transport me a short distance in time so that I can see for myself that it works?"
At that point, there's an either/or decision point in our logical matrix. We can either have the machine shown to us and demonstrated, or we can get a big song and dance on why said machine is unable to be exhibited or demonstrated for us. And there you have it. This article is chock full of all kinds of big claims, but where's the proof of any of it?
