The topic for this post is “Space,” but it could also be “Media Criticism.” New space blogger Eric Collins emails:
You may have noticed the post on HobbySpace about the so-called hyperspace drive. The linked-to article from the Scotsman is annoying on several different levels. I was really disappointed that this article was making it onto several highly visible blogs (including slashdot).
I was preparing a long blog rant about this incredibly speculative, bordering on crackpot, theory when I finally came across a link to the original article posted at New Scientist. This article is much more informative and manages to sufficiently address the speculative nature of the proposal. So, rather than blog about it myself, I decided that I would just try to make sure people were aware of the New Scientist article. And, since your blog is much more visible than mine, I figured you could probably get the word out much more effectively than I could.
Yes, I was going to post something about this, particularly after Glenn picked up on it, but I haven’t had time, so thanks to Eric.
The strangest thing (of several strange things) that jumped out at me about the Scotsman article to me was this paragraph:
…if a large enough magnetic field was created, the craft would slip into a different dimension, where the speed of light is faster, allowing incredible speeds to be reached. Switching off the magnetic field would result in the engine reappearing in our current dimension.
Huh?
Even ignoring the mumbo jumbo about magnetic fields and different dimensions, this is the equivalent of saying “the solution to land-based transportation is to raise the speed limit from seventy MPH to 500 MPH,” ignoring the fact that no one has a car that can drive this fast. There is no description in here of how one goes faster than our “dimension’s” speed of light, even if the speed of light is faster. The problem isn’t speed limits, it’s propulsion. Hell, if we could approach the speed of light here, that would be a huge breakthrough. Once we figure out how to do that, then we can start worrying about how to increase the speed of light.
This is another example of how science and technology stories can get mangled by reporters who don’t have any idea what they’re writing about. And the New Scientist piece is, indeed, much more interesting (and describes what actually is a new form of propulsion, by converting electromagnetic forces to gravitational forces), to those who (unlike the Scotsman reporter) are numerate and literate in basic physics.
