- mikercampbell 3y agoI literally gasped after reading the synopsis. It is such an incredible idea, that seems strangely (and probably wildly incorrectly) simple.
- rvnx 3y agoMaybe they mean FM waves by "radio" ? (which would then imply, "FM waves" versus "terahertz waves") But I agree it sounds funny. A bit like, "we found faster than electromagnetic waves: we are using light"
- giantg2 3y agoThey probably mean faster as in transmitting data more quickly than with lower frequency. The EMR travels at the same speed, but you get more throughput.
- munchler 3y agoTalk about burying the lede. We've discovered faster-than-light communication... and we're using it to make tamper-proof ID tags.
- godelski 3y agoIt isn't uncommon to use verbiage where speed is associated with frequency rather than the speed at which a wave propagates across a distance. I'm not saying we should say things this way, but that it is not uncommon. (Consider the audience. It is the general public who does not have such well founded notions. Again, not that they shouldn't, but here we are)
- samatman 3y agoThere's nothing wrong with saying that blue light is faster than red light, in context, it obviously means the frequency. It might be better to specify, but in many contexts that isn't necessary. But you can't say that blue light travels faster than red light, because that's obviously wrong.
- AndrewKemendo 3y agoThe problem is that this serves to amplify ignorance because someone is going to think waves travel at different speeds
- metaphor 3y ago> someone is going to think waves travel at different speeds That's a good thing, right[1]? Something about "the one thing all models have in common..." comes to mind. [1] https://en.wikipedia.org/wiki/Velocity_factor https://en.wikipedia.org/wiki/Velocity_factor
- godelski 3y agoBut waves do travel at different speeds. In fact, different frequencies travel at different rates in different media. Only the speed of light __in a vacuum__ is constant. Which is pretty rare. So rare that even space doesn't have a pure vacuum, though 1 hydrogen atom per meter is pretty close if you ask me. But I did notice the pun.
- AndrewKemendo 3y agoIt's really all about the frequency of puns
