What's she's doing here is kinda impossible: She's trying to convince us that these things are impossible which implies she knows everything while yet confessing that she doesn't know how to make these things possible which would thereby infer/confirm that she doesn't know everything. Isn't science just great? You can pick and choose what's true and isn't true. How convenient. Oh, she also chose as a reference a well noted and famous scientist to further convince us that she knows everything however the reference, and she admits this, debunks her suggestion about plasma; hence she could be wrong about everything which thing she subtly hints at. And so, in the end I just got so frustrated that I wasted time watching yet another so-called science lesson that did nothing but expose itself as anything but education. Explains why America is in shambles today. This is what the past several generations have been raised on. Welcome to the opposite of space exploration. It's no wonder than nobody knows what's causing the earth's exponentially increasing catastrophic activity; see why I don't trust their global warming theory which if true would've caused us all to be dead and cooked a long time ago already! They know what's causing the earth's problems and they're using global warming to blind us to the realities of our doom which is already upon America! Look at the recent annual increase of earthquakes just to give an easily recognizable basis for reality: 30,000 and then 60,000 and then 120,000 and then 300,000 does this look natural to anybody? Does this look like global warming is coming on slowly and death can be averted? Didn't think so!
