Magical Realist: It's called the law of conservation of energy. Also known as the first law of thermodynamics. Quantum tunneling has to do with the wavefunction of an object having a non-zero value on the other side of the "wall". Wormholes don't exist, as far as we know. And if they did, they wouldn't make things disappear without trace. Nobody has ever seen one do it, really. What does that suggest to you? Oh yes, this reliable video of yours may be the first time in history that such a thing has been observed, despite the fact that it looks just like an amateur video edit. Been there, done that. Hume also had things to say about miracles. Did you get as far as that part? Yes it does. That law is known as conservation of angular momentum. Science is based on regularities in nature. You're correct that such things aren't logically necessary. We can imagine a universe which had no regular laws, perhaps. But we don't seem to live in such a universe. See what I did? I predicted your response before you made it - then you went ahead and made it anyway. I hate to break it to you, but it is false that anything is possible in our universe. No. It's mass would add to the mass of the black hole, and that mass increase could, in principle, be measured. Not without a trace. There'd be some molten metal, some hot gases etc. Try to remember what we're talking about here. We're talking about a car that you think just vanished off a road. It didn't explode. It didn't melt. It was just edited out vanished. What do you think is more likely: that somebody stole it, or that it was lifted into an alien spaceship and carried away to Mars? Any ideas? Or do you think both things are equally likely? The probability of a grand piano appearing is so minuscule that we can all but guarantee that such a thing has never happened in the lifetime of our universe. I'm guessing you have no idea of the absolute tininess of the probability of such an event. Your chances of winning first prize in the lottery every week for a year are enormous in comparison. If you can't trust in the regularity of everyday experience, how do you get through your day? When you go to eat your wheaties in the morning, does it worry you that a pink merry-go-round might drop from the sky and kill you as you sit at the table? Are you worried that you car might turn into a turnip at any time? Do you lie awake at night worrying about whether the sun will rise in the morning? Or that spotted pixies might suddenly appear and conduct bizarre sexual experiments on you? It must be truly terrifying to be you. That's if you're for real, of course. Actually, probably not a law this time, but an absence of the right conditions for it to occur again. Oh, and by the way, if you're wondering why I believe the big bang - a one-off occurrence - happened, it's because there's plenty of reliable evidence that it did. Unlike for the disappearing car. You assume there are millions of inhabited planets, but on what grounds? Just like the disappearing car, you have nothing to base that assumption on. I, on the other hand, acknowledge the possibility of other inhabited planets, while waiting for some actual evidence to come in. And unlike the disappearing car, there's nothing to prevent alien life, as far as I am aware at present. And let me just add: there's no reliable evidence for any alien life visiting earth in flying saucers. Why do you think so? Again, this is just speculation based on ignorance. That's a straw man - something I never said. Just to be clear: no, I don't think that we have discovered all there is to know about the universe. And like I said before, I think I have a better grasp of what we don't know than you do.
