You mean the same Tempel 1 where a crater was created that is far too big to have been created in rock? That Tempel 1? The same Tempel 1 from which thousands of tonnes of solid ice were excavated? That one? Where there was zero indication of any electric woo, despite Thornhill's lies? Are we talking about the same comet? Fail. Learn to understand the difference between dust and rock. We had that stuff explained in primary school. Perhaps you never made it that far?
