akya: Skinny wormholes? I've been sending messages through them before it was cool and mainstream. It involved a lot of complicated obscure science that you probably aren't aware of.To tell you the truth, I really liked some of my earlier messages, but lately they just aren't as good as they used to be./I sold out//Mostly sending advertisements now.
UberDave: The need to pull their head out of their ass. All you have to do is direct a tachyon beam towards an itinerant pulsar.
James!: Try reversing the polarity. That usually works.
jfarkinB: Thou shalt not violate causality within my historic light cone. Or else.
NeverDrunk23: Do we really trust humanity not to fark things up if given access to time travel?
t3knomanser: NeverDrunk23: Do we really trust humanity not to fark things up if given access to time travel?If time travel exists, how do you know we haven't already farked things up?
t3knomanser: You need a hypothesis before you can test the hypothesis
8 inches: I'm getting a kick as I am currently in the process of filing a patent for a time machine./Serious//Wife is about to divorce me because she thinks I'm crazy///I am
ManateeGag: UberDave: The need to pull their head out of their ass. All you have to do is direct a tachyon beam towards an itinerant pulsar.no. I think they need to bounce the graviton particle beam off the main deflector dish.
xkillyourfacex: I think submitter was indicating the impossibility of doing the experiment renders the hypothesis nothing more than mere speculation.
To The Escape Zeppelin!: Columbus starts a war against the Ottomans instead of going west and history turned out so bad that people went back in time to convince him to kill some indians instead.Pastwatch: The Redemption of Christopher Columbus

ikanreed: jfarkinB: Thou shalt not violate causality within my historic light cone. Or else.Causality isn't tied to the speed of light. Just all heretofore seen causality. This wouldn't represent a violation.
Grungehamster: Anyone know of any good science fiction stories where they create a closed loop communication method through time and one of the following scenarios happens:A) The method is too overly used to be very useful in the big picture. Every few months, weeks, or days SOMEONE with access to the device has something they feel is worth trying to change so they keep having to keep resetting the loop so messages can't address problems that aren't immediately apparent.B) The people in charge put safeguards against A but they are too cautious, resulting in no one using the device because someone paranoid about an even worse eventuality that might not be prevented should you waste the loop being created.C) They actually make lots of the devices for different purposes/time frames to avoid the temptation to go to either extreme but the man hours and resources necessary to maintain such a complex system comes at the cost of other monitoring being ignored and when the big crisis hits there isn't enough time to warn the past before everything ends.Sounds like stuff Alan Lightman would write. Anyone familiar with those sorts of stories?
Nicholas D. Wolfwood: I've said it before and I'll say it again, no one should be allowed to seriously kick around time travel until they've read James P. Hogan's 'Thrice Upon A Time' at least twice. (His 'Proteus Operation' is a good time travel / alternate history story, too.)
Nicholas D. Wolfwood: and cats.
jfarkinB: Please elaborate. "Effect precedes cause" is about as close to a definition of causality violation as you can get. And time is tied by its very definition to the speed of light -- it's just geometry. If you could "travel faster than light", you would be traveling through time.
ikanreed: But you couldn't affect that in some reversal of causality.
Nicholas D. Wolfwood: Every time a thread like this comes up, it just makes me sad. The comments are over 95% Star Trek and Doctor Who. Nothing wrong with that, I love 'em both. But seriously, folks, READ A BOOK ONCE IN A WHILE!
Nicholas D. Wolfwood: Again, read 'Thrice Upon A Time'. Yeah, I know, I harp on this a lot. But one of the things the team was sweating over while they were trying to build - and test - their theoretical model was its implications for free will versus predestination. For my money, I like the way they went about it, and I like the conclusions they came to. It was - satisfying - in that it managed to reconcile observed experimental results with observed reality, and many philosophical points. If anyone wants to dig into it without reading the book, let me know, and I'll abstract the whole thing and post it. I feel very strongly about the model they ended up with.
