you are confusing the issue again. the time traveler CANNOT see you simultaneously (in their frame) at two different times your frame. that amounts to saying that they can, at the same time, watch two luvluvs at different points in luvluv's life. That was your claim, that god can see us all at once, from his point of view, at all points in our time line. In other words god can see an infinite number of luvluvs at once. That is far different than time travel. please don't take C. S. lewis seriously, the man is not really a profound scientist/thinker. He was just coming up with some half-baked mumbo jumble to try and give people like you some sort of intellectual satisfaction. He has no justification for his thoughts other than he thinks they explain something, nor did he really attempt to align them with all of science and what we know. |

hi tron,
welcome to our little discussion. Quote:
The first problem I mentioned way back still would not be addressed by this. There is no absolute, or universal, time axis to plot the universe against. Einstein showed that idea was an error of human imagination. Every object in the universe basically has its own local rate of time increase. Quote:
Do you have any formal justification for other types of travel? If not then it simply a product of your imagination and we really can't take that stuff seriously as 99% of what we humans think of the universe (new ideas) are wrong in the reality. That is why I don't take C.S. Lewis seriously, there is no attempt at justifying it with reality or checking for consistency, just a man and his musings- that's all. As an apologist he isn't even one of the better ones, he is more on the Josh McDowell level rather than the W. L. Craig level. That is also why I have only read a little of his works, the level of rigor is pretty low, so no I have not read the screwtape letters just as i will not read what every single yahoo out there has to say about the world. like this fella here: <a href="http://www.timecube.com/" target="_blank">http://www.timecube.com/</a> Quote:

If we imagine this as a graph, where the x axis corresponds to time and the y axis corresponds to space, you can see that a point could remain stationary on the x axis and move infinitely far north and south on the y axis. It could therfore be at more than one place at one time. The axiom that an object can only exist at one place at one time is not an axiom that applies to all existence, it only applies to objects residing in a space-time contiuom where the flow of time has only half a dimension: irreversibly forward. If an entity exists, or has access to, a backward dimension of time, it would be the simplest thing in the world to be in more than one place at the same time. He could go back to a specific time, say Thursday at 3:00, and go back to a different place than he was the first time he travelled through Thursday at 3:00. Think about Brian Greene's analogies from the Elegant Universe. A being in a one dimensional universe would think it was impossible to move laterally. He would exist on the line and consider lateral movement an absurdity. Similarly a two dimensional object would consider the words "above" and "beneath" to be logical absurdities. They would categorically state that above and beneath are impossible. Similarly, we draw the same conclusions about time. But string theory shows us that there are more dimensions of space, so why not more dimensions of time? It also shows us that two-dimensional objects aren't just abstractions, they actually exist. The analogies therefore aren't fairytales, they are concrete in reality (though, obviously, one dimensional entities can't think). Quote:

Let's assume our time traveller was immortal. That is, within his own time, he would never die. Let's assume that, from his observational point of view, that he would never be bound to the flow of time in our universe, the universe he was observing. This time traveller could go forward through all time, stopping at every millisecond in our time line and going through every spot in our universe recording observations. From our standpoint, he would have "functionally" simeltaneous knowledge of all of our actions and choices WITHOUT our having to have temporal extent. It would be simeltaneous to us, even if it was in some sense sequential to him, because he would not have been on our time line and could, after he had finished making observations, return to the big bang on our time line and observe from there. He would then have observational knowledge of everything we have done, knowledge gained solely through OBSERVATION, NOT THROUGH PREDESTINATION, thus enabling the time traveller to be functionally omniscient and us to be functionally free. If it is possible to skip over time, backwards and forwards, then this view is very logically possible. You are simply begging the question when you declare time skipping to be impossible when you don't know that it is. The wormhole theory of Stephen Hawking and certain aspects of String Theory still hold it to be a distinct possibility. You are still well within your epistemological rights to disbelieve in out of time, but to declare it impossible would be incorrect. wdog: Quote:
It's safe to say that C.S. Lewis was not the smartest person who ever lived, but it is also safe to say that he is smarter than you or I. If you really haven't read much of his work then you're opinions on his ability aren't really worth much. Might I ask what book you did read that gave you such a low opinion of him? (I hope it was more than one.) Quote:
And as far as I can tell (if I am understanding your terms) the lack of a universal time coordinate works IN FAVOR of out of time, not against it. Also, the finite extension in space would not prevent it, as I attempted to explain in the illustration about the immortal time traveller. tronvillian: It's an honor to be on your side for once. |

We don't draw conclusions until we have a well accepted theory luvluv, you are trying to draw conclusions based upon a postulate whose plausability hasn't even been demonstrated beyond some simple spatial analogies. Quote:

We WOULD have to have temporal extent luvluv, for him to race ahead to next week and observe me there. I am not there, I am here. Quote:
consider the implications for xtian theology. god knew before he created adam that man would 'fall' and also that he would have to flood the earth. then why go ahead with something that you don't like? and act surprised by the fall and the flood when you had foreknowledge? Very illogical actions. Quote:
What I am saying is that if i wanted to know as much as i could about the physics of time, I would study what is established as science. That is what we are talking about here, a scenerio for the physics of out of time. Start with the established results, then possibly maneuver out into philosophical interpretations. Philosophy is fine, and the ideas are generated by some truly brilliant poeple, but that doesn't establish the correctness of an idea. Saying that CS lewis is smart therefore I should believe him would be to abandon logic and reason (appeal to authority). I am not saying that C. S. Lewis is a dummy, I am simply claiming that his ideas appear to be less developed than say a W. L. Craig and that he is not an expert on relativity. I am perfectly within my rights to say so without any ad hominems. My honest opinion is that the likes of C.S. Lewis and Josh McDowell are for people who already believe or for people who don't care to think deeply. I read some, but not all, of Mere Christianity and Evidence That Demands a Verdict. After being able to pretty much tear apart arguments as I read them, I was dissappointed (this was when I was a Christian looking for substantiation of my religion, I wanted irrefutable proof). I then went on to work that I considered as more rigorous and hopefully satisfying (Craig for example). Utimately the search is futile for a person like me, I have no choice but to obey intellectual honesty and conclude that Christianity is not true. Quote:

I see merit in the question of whether there is an absolute present. Two points can't be in the same space at the same time, which imposes a certain degree on consistency on objects with different time scales that are in proximity to each other.
Consider the twins problem. One twin hangs out on Earth, the other zips out and back to a distant star at close to the speed of light. Just before they leave, and at the moment twins reunite, they need to share a common point in time and be close in space, in order for the meeting to happen. They need to share, in other words, an absolute present. Special relativity can be used to tell us from either twin's perspective, when that instance of coinciding will happen. The amount of time that will have passed between the departure and arrival of the travelling twin will be different for each twin, but the two time scales have to match up sometime. This is true even if the twins are never have the same interial reference frame because the travelling twin buzzes by the stay at home twin, instead of slowing down to chat. Moreover, stay at home twin, if he were so inclined, could pull out his computer and calculate precisely where to send a speed of light communication to the travelling twin so long as the travelling twin kept to his itinerary. Thus, with a fairly modest set of facts, it is possible to translate from one interial reference frame's time scale to another for any practical purpose. It is only modestly more difficult than converting from the English system to Metric, although it has more real life physical meaning. It is probably impossible to know if there is physical meaning or importance to cases where there is no ultimate contact. But, there is no real reason to think that relativity is "observer dependent" in the sense that it produces different physical consequences if an observer does or does not observe an event in the way that quantum theory does. Put another way, GR and SR are internally consistent, despite it not being obvious that differing time scales for different travelers could produce such a thing. |

Quote:
If God exists outside of our time line, and is not in anyway effected by it, then it is perfectly within his power to observe our universe from the end to the begining if he wants to. Consider: if God made the universe, then He necessarily made it from outside of our physical universe. Much like an author, who writes a book, must exist outside of the book to write the book. It would be impossible for one of the characters who has his only existence within the book to have written the book. We can say that God created this universe in much the same way that an author creates a book. For the sake of clarity, instead of a book, lets use a comic strip. Now, for the characters within the comic strip, there is a time frame that passes from left to right one frame at a time. Causality flows in one direction. But the creator of the comic book, if he chooses to, can READ the comic strip backwards REGARDLESS of the proper flow of time within the comic book. In fact, the author can even WRITE the comic strip backwards, so long as, when read forwards, maintains it's causal flow. In other words, to an external author, the flow of time or entropy within his creation is totally non-binding SINCE HE IS NOT IN THAT CREATION. If the universe exists to God as a comic book exists to it's author, (and it must to any actual God) then it is absurd to speak as if the flow of time within the universe limits the observational ability of someone outside the universe in their own time. Objects would not have to move backwards to be observed in reverse order. Again, the tape analogy is appropriate. Say you had a video tape of an explosion. It is true that the laws of thermodynamics say that the debris of an explosion cannot comustively UNITE instead of DISSASSEMBLE. But a person with a VCR, who exists OUTSIDE of the events on the tape, can OBSERVE them in reverse order. I ask all these in order to entertain your argument, but all I really needed to ask you was this: what makes you assume that omnipotence could not occassionally reverse the law of thermodynamics if He wanted to? Your simply begging the question again here, because if the being we are discussing is God, there is no way he could NOT be capable of reversing the law of thermodynamics if he chose to. (I have heard, after all, that this possibility has a non-zero probability of occuring at any rate). Quote:
All time in our universe moves along at a second per second, and you are assuming that God is in the tide of the time waves and must Himself go along with the flow. But He is not bound at all by the flow of our time, anymore than you would be bound by the flow of time in a book you are reading. You can stop and put the book down for two weeks and when you pick it back up the characters, relative to your observation, are still in the same place they were two weeks ago. They have remained frozen in time for two weeks FROM YOUR OBSERVATIONAL STANDPOINT. ("A day unto the Lord is as a thousand years, and a thousand years as a day...") Quote:
Similarly for the future, it does not matter if you are not in the future "NOW" because "NOW" is not what He is looking at when He looks at the future. You don't have to exist there "NOW" for Him to see you, you only have to exist there "THEN", at the time He is looking at you, and of course you will. Again, if you were a character in a book you might consider yourself to be at a certain point of time, which God might consider page 27. To you, the events that, for God, comprise page 32, do not exist yet. But for the observer from the outside, it does, you have just not intercepted it yet. Again, you are assuming that God cannot make a 4-dimensional reality of free-willed creatures in the same way that we could make a book, and observe it (and even act in it) in whatever order He wished, even though to us, within the "book" it appears as if everything is flowing causally, inexorably and necessarily, from one point to another. Again, given omnipotence, it is difficult to see why, exactly, God could not do this. This is what you need to explain: why an Omnipotent God could not create a reality seperate from His own which is analagous to an author's relationship to his own literature. Quote:
Quote:
You do realize, this being the case, that you cannot say that omniscience and free will are incompatible? If you concede that then this argument is over. I never pretended that I could prove to you that out of time was TRUE, only that it was consistent with omniscience and free will, and not a logical contradiction for an Omnipotent Entity outside of this universe, which we presume God to be. That's all I need to show. You're the prosecuting attorney in this case, wdog, trying to state beyond a reasable doubt that omniscience and free will cannot co-exist. All I need to show is a reasonable scenario by which they could co-exist to the observer in question, an Omnipotent Entity outside of our universe. I have done so. Therefore, your case is not beyond a reasonable doubt. The laws of logic, like the laws of the court, do not abide by what YOU THINK the reality of the case is, but WHAT YOU CAN PROVE. And you cannot prove your argument any more than mine, so in this case the defendant, God, goes free. His existence, with all the attributes described in the Bible, remain possible. Quote:

And further, wouldn't God know what team would be enabled to win the Superbowl BECAUSE he said it, so wouldn't He just say that team? His words would be a causal agent, and He would have known from eternity that He was going to say it and that His words would cause the team in question to win (directly or indirectly). And it does not follow, that from refraining from speaking, that God COULD NOT SPEAK if He wanted to, so He would retain free will. Not that this scenario has anything to do with what we are discussing. Quote:
Quote:
As for C.S. Lewis, I would say read more of Him. Lots more than half of Mere Christianity. If you demand demostrative 100% proof for everything, there should be a lot more things than God that you disbelieve in. People are capable of belieiving in things they have no direct, certain evidence of. You do it everyday. To be frank, I think that anyone who demands 100% proof for anything is probably looking for an out. No one in your life could prove to you 100% that they even exist outside of your mind, you just believe they do because at a certain point doubting everything you can doubt becomes unreasonable. |

[quoet]hi tron, welcome to our little discussion.[/quote] Does anyone else fine it irritating to be "welcomed" to a discussion on this board? Besides, I was the first one to reply to luvluv on this thread. [quote]I see what you what you are trying to point out here, but I disagree. I think that we exist temporally in the moment (ours), not extended in all time. I would have to see some kind of formal justification to believe that we have a temporal extent (if that really means anything).[quote] You disagree that our universe could be analagous to the line rather than the point? Then it is up to you to demonstrate the logical impossibility of such a scenario. Quote:

Logically explain this then : what would happen if you went back in time and killed yourself? please present a complete and logical answer without just saying that somehow, by a wave of a wand that something like out of time takes care of that problem. Quote:

I can say that omniscience and free will are incompatible based on what we know about our own universe. You haven't really added anything new here, so why should I change my conclusion. Quote:
Quote:
you want to talk logical possibilities. from what you have said the following logical possibilities arise. 1) God could, if he wants to, go back to your birth date and kill you. that would definitely change your existence. So god has two choices, to kill or not to kill. They both present different timelines for you. Now you say that god has always known that he wouldn't kill you, but why can't he just suddenly (as it appears to us) change that fact? He is after all omnipotent and can do anything. If he does change his mind, the all that he had seen ahead for you would all be false, therefore he didn't have accurate foreknowledge of his own actions. You cannot get around these paradoxes if you want to talk about an atemporal being interacting with a temporal universe. 2) what if god told you right now that you were the next sniper victim (again, he has the choice, he is omniscient), and he told you when and where. You would alter your actions, hence your future, based on that knowledge. The act of giving you that knowledge is a temporal act with temporal consequeces, an atemporal being cannot escape that. The temporal choice presented to god gives two possible futures, the only way for god to preserve perfect foreknowledge of his own choices is to never interact with us temporal beings. If he can never interact, then he is not omnipotent. this is from W. L. Craig at: <a href="http://www.leaderu.com/offices/billcraig/docs/stump-kretzmann.html" target="_blank">http://www.leaderu.com/offices/billcraig/docs/stump-kretzmann.html</a> Quote:
