"However, I read last week that they've also performed the first instantaneous teleportation of a bunch of particles (50, I think!) so I suppose that counts as faster than light travel, too. Sort of. And finally, to go completely off-topic, I read also that some clever guy had managed to slow light down by way of an impossibly complex device, so it only travelled at a few mph. Where do these guys get their ideas from?" I'm no expert but I don't think that teleportation thing they did last was instantaneous. They teleported photons (a laser beam) right? Just because they teleported it doesn't mean they'd have to teleport faster than light. Can you post a linkg to that slowing light down thing. I'm quite interested. Slowing light down isn't all that special. Light travels at 300000Kilometer/s in a vacuum. But put it through a different substance and it will move slower. Maybe the scientist made a very special substance? Yes quantum thingys are totally weird. Particles that can be in two places at the same time, time travel, etc. It's all possible there. "What you are talking about is called Moore's Law. According to Dr. Michio Kaku, Moores Law breaks down as we appoach the molecular level. (we're almost there)." Yeah you're right. But I think we still have a long way to reach the molevular or atomic level. You keep hearing about new breakthroughs, but I think it will still be some time before they can be made useful in the consumer market. This post has become two(three) topics :)
