@TM:
“maybe consider them to be like magnetic fields (VERY crude analogy). a body/solution/molecule subject to a magnetic field (for example, in an MRI/NMR (nuclear resonance imaging) machine will become excited. This excitement has a signiture (likely multiple signitures) that may register in different ways. One of these might well be captured by: infra-red/spin-spin coupling/ etc. (i.e. something that does not get sucked into the black hole).
i hope this is a little clear - sorry, i’m no astrophysicist, however i do find imaging fascinating.”I find you fascinating! ^_~ It is not everyday that I get to meet someone with such a great understand of both medicine and cosmology :D
as opposed to “cosmotology” - a science that yet eludes me :)
(and thank you - you are too kind)
Yes, but cosmic strings evolve and eventually decay due to the radiation and energy they give off. How would you get two cosmic strings together or at least close enough to a black hole to do this? Then you would have to find some way for your time machine to loop around the cosmic string, as well as well the necessary mass energy too travel further back in time.
duh, I know that. :-? I was just saying that Cosmic Strings were at least more feasible then using wormholes.

Hmmm… went back and killed parts of my family, eh? This should be “interesting.” :wink:

TM, I’d watch out for older versions of TG if I were you!
Do not worry, I will! :D
Dont worry Tm can Take TG ne day. she can Launch a Cosmic Happy ray and will Rid TG of his Evil Thoughts ;)
Evil thoughts, huh? :roll: That’s interesting coming from you. :wink:
o Im not Evil! i am the Good guy in the Political Compass :) i just use Some Dark Means to Achieve the Better Outcome for the Human Race :)
seen the teminator? it has interesting things about time travel like if the lab is destroyed then the liquid metal guy would not egsist
Terminator’s got a good point, if someone has come from the future they probly would’ve been sent to some place for insane people.
I doubt you could travel back that far.
@Deviant:Scripter:
Well F_alk, I hate to use Stephen Hawking again, but I think I must:
Hawking realized that if a particle/anti-particle pair came into existence near the event horizon of a black hole, one might fall into the hole before annihilating its anti-particle. The other particle could then escape the gravitational clutches of the black hole, appearing to an outside observer as radiation."
Which is an “out-dated theory” / “popular science explanation”. It’s wrong, i once knew the correct mechanism, and could surely find the FAQ where that was explained correctly.
@TM:
For example, traveling back further back in time we would open ourselves to many different paradoxes. What would happen if I traveled back in time to killed my father, heaven forbid?
…
Time no longer follows a straight line but branches off into many different universes.
To the second: That’s probaly what is called the Many-worlds-theory, first mentioned by Everett and Wheeler. This actually would allow time travel without paradoxa: If you travel backwards, you will not end up in the “world” that you actually came from. You could kill your father there, and never be born in that world, but still you will be born in yours.
But there are other things which are opposing time travel:
Anyone, as a living being, consists of matter. Matter and Energy are equivalent. Now suddenly (as you travel backwards) the universe lends itself energy from the future? I think the conservation of energy (or any other conservation laws) ís the most powerful argument against time travel.
Another example: We believe (and have good reason to do so), that the overall universe is electronically neutral: same amount of positve and negative charges.
Now, (after having splitted a H atom) if you take with you (going back in time) a single electron, and leave the proton “in the future”, you violate that law for some time.
I grow more and more opposed to time travel :)
now the objective of the terminator doesnt make sense. cus if he kills jon conner the humans lose but then it erases the reason for the T1000 to come in the first place so he realley doesnt die cus the T1000 cant come so there for it is impossible for jon connor to die and the terminator is on a lost cause ;)

Nah, I’m sure we can get time travel to work. However, you can’t go back any further then when you stepped into the time machine - ruling out the idea of T1000 going into the past. :-?

Well, of course, i am opposed to travel backwards. Forwards is no problem, we do that all the time :).
And what use is a time machine, when you can’t get out “before” you got in?
Do a lot of things at once within a short amount of time –- or even no time at all? :-?
what about stoping time?..…
Might work… though there are problems when dealing with it. (ie what happens to your mass?)
Problem is, you can stop “your” time, but not “the time around”.
If you did that, that would be effective time travel, as you could travel faster than the speed of light.
Heh, traveling faster than the speed of light… Probably can’t be done.
