Why I hate science reporting
Could all our blunders be reversed, our failings eliminated? Perhaps so, if an Israeli scientist's research is to be believed. With the help of Prof. Amos Ori, we might just be able to go back and stop the screw-ups from happening in the first place.
No, they can't, because it doesn't work that way. Here's why (from later in the same damn article):
But don't pack your bags and get ready to go dinosaur-hunting yet. "We, however," he cautions, "could not return to previous ages because our predecessors did not create this infrastructure for us."
If time travel is ever invented it will only be able to take you back to the point where it was initially invented, and I don't think it could be used to go appreciably into the future (the accounts I've heard all require time dilation in order to move into the future. How exactly it works is irrelevant since it's impossible anyway).
The other is about the Casimir effect (if you know what it is, you're probably already groaning).
The article's headline is "Levitation breakthrough proposed". The last paragraph of the article says:
The scientists say there is no likelihood in the foreseeable future of humans being able to levitate. "At the moment, in practice it is only going to be possible for micro-objects with the current technology, since this quantum force is small and acts only at short ranges," said Prof Leonhardt. "For now, human levitation remains the subject of cartoons, fairytales and tales of the paranormal."
I hate editors. Why do they put these ridiculous titles and lead-ins that are flatly contradicted later in the article? Why can't they report science breakthroughs (or theoretical developments) for what they are, and not a pile of sci-fi garbage that they're not? It boils my blood because this is science that anyone who's taken "Intro to Modern Physics" wouldn't get wrong, you don't need a PhD to see that it's crap.
And it's not like the actual science is boring. The Casimir effect article is talking about negative refractive index materials being used to eliminate the quantum attraction between two nanomachines. Why isn't that exciting enough? Why do they need to add levitation? (I find nothing redeeming about the time travel one, since he just proposed a new technical mechanism for something that's beyond our technology but we already knew was plausible. It's not news.)
All of this reminds me about an article where someone claimed to have "solved" the "Twin Paradox" (this was months, probably a full year ago, I have no chance of finding the offending article). My head nearly exploded, because there's nothing to solve. It's only a paradox if you're not thinking about it right, and again, any intro physics class should explain why it's not a paradox (or any book that contains any real treatment of relativity).
It's just so aggravating to see science distorted into something it's not, when what it actually is is so fantastic to begin with.
