Post by: Foxpup on June 07, 2013, 06:03:09 AM It's not really a hole in time, they're just slowing down and then speeding up photons so that to an outside observer it appears* that the photons have briefly ceased to exist and they'll be all like, "Whoa, where'd they go?" No doubt this has really cool applications for secure communications and whatnot, but it does not "tear a hole in time". ::)
*Actually, they don't just appear to not exist, they have ceased to exist temporarily (sort of), and cannot be observed or interacted with in any way. Relativity is funny like that. Quote In theory a thief could use time cloaking techniques to enter a building, steal cash or valuables and exit before their image was recorded on security cameras. ??? Um, no, they couldn't. The reporter is confusing people with subatomic particles again. It's a surprisingly common mistake (they did it with quantum teleportation, too), although I really don't understand how anyone could make it in the first place. A person is nothing like a subatomic particle! Why would anyone even think that?Title: Re: Scientist tear a hole in time! Post by: mprep on June 09, 2013, 10:44:30 AM Da fuq? OK, that's creepy.http://www.dailymail.co.uk/sciencetech/article-2336425/Scientists-create-device-tears-hole-time-enabling-undetectable-secret-messages-sent.html Title: Re: Scientist tear a hole in time!

Why would anyone even think that?Hiding single electrons for 0.00012 seconds is the same as making a human being invisible for several minutes, right? ??? It seems like a reasonable leap in logic to me! Title: Re: Scientist tear a hole in time! Post by: RagnarDanneskjold on June 15, 2013, 01:44:54 PM In the real world, these types of 'temporal cloaks' and similar photonic time trickery are used to achieve wide band visibility into the immediate future for precision sensing/targeting/navigation for satellites and other fast moving equipment.
Where it gets interesting is when these temporal anomalies are cascaded together to create a chain or echo chamber, then we could be talking about some serious time vision capabilities. So , if you could see 30 seconds or a minute into the future, what would you want to see? (other than the price of X) Title: Re: Scientist tear a hole in time!
