Time May Fold Back on Itself. Or Something

[Tuckerfan]

Mind bendingly serious article on an experiment to see if time travelling particles are possible.

If you can do that, Cramer says, why not push it to be better-than-instantaneous, and try to make the signal arrive before it was sent? His extra twist is to run the photons you choose how to measure through several kilometers of coiled-up fiber-optic cable, thereby delaying them by microseconds. This delay means that the other beam will arrive at its detector before you make your choice. However, since the rules of quantum mechanics are indifferent to the timing of measurements, the state of the other beam should correspond to how you choose to measure the delayed beam. The effect of your choice can be seen, in principle, before you have even made it.

That’s the easy part.

Ouch.

Ah, but it already did hurt. You’re just remembering what it hurt like in the future.

Keep talking geeky. It turns me on.

now feeling the pressure

How about a nice…back rub? We can converse about something geeky then!

Time running backward is part of nature? ::head asplodes::

I was watching the Science Channel and they were talking about Hawkin’s Paradox and black holes and I thought my brain was going to melt.

Hey! Let’s build a time machine, go back in time and show the article to Einstein!

[Sunspace]

Me, I’d like to go back and tell myself to ask Anna-Marie Hubbard out, dammit. Greatest regret of my life.

[ivylass]

Yes, but see, under this theory, you already did ask her out.

[Least_Original_User_Name_Ever]

You already did everything you were ever going to do with her as well…
…so…was it any good, tiger?

Didn’t you mean you wanted to go back in time and show the Particle to Einstein ?

Back in time, schmack in time. I just want to be able to hop ahead 24 hours, buy a paper, and then come back to where I was.

And buy a lottery ticket.

My luck, that would be the one edition where they had a misprint.
