I wonder if (assuming he's not just making up the most random shit he can to try to milk gullible idiots for cash) that it's Bennett needs more of whatever meds he's on or just reaaaally needs to lay off whatever he's been taking. Because if it's not just a cash grab, there really isn't much to say in response even.
Sure, I can say that ice IS a crystal, so unless whatever rings he's talking about are cubic zirconia or whatever, it's meaningless. It'd be like saying "It's not iron, it's made of metal!" Like, sure, that might be true, but unless you specify which one what are you talking about?
We can, as TheKingofRhye mentioned, point out how useless it would be to recieve a broadcast from Saturn and need it sent through the moon to reach Earth. The Earth to the Moon is (on average) 238,855 miles away. The Earth to Saturn is (on average) 887 million miles. At the closest, it is 746 million miles. And on top of that, what happens when the Earth is between Saturn and the Moon?
But that's the sort of thing I mean. Nothing he writes makes sense. Just a string of "Well, that's not true. That doesn't work. We have no measurements of that claim. Can you demonstrate that aside from just stating the claim?" rebuttals.
