Topic: Do you think time travel would be possible? Why?

Space and time cannot be thought of separately, they are linked. Travel fast enough through space, and time is effected also. Human's will one day harness that power and destroy this universe, with me at the helm, mwahahaha!

I once read an article that UFO's might be our buddies from the future that time travel to the past(our time)
so..yeah
but it's not totally proven

You mean not proven in the slightest bit, I take it.

well if u have a time machine youd have to go through confusing space time continuom and other laws that make it kinda unfun (like how bill and ted have to keep going back in time to fix everything)

Since I believe in God I don't think it's possible to travel back in time. I believe He designed it that way so that it always goes forwards. I don't believe time and space are infinite either. I believe they're finite like everything else in this universe.

So basically, you're going with the "LALALALALALA!!! I'M NOT LISTENING" arguement then since the infinity of space and time (or the progression of existance rather) are pretty much proven... Unless the big crunch is gonna happen then all bets are off. And if I take on my religious pants, then who are you, a lowly human, to presume to understand any part of god's plan? Isn't the whole point that god is more then a mere human? So how could you possibly even begin to argue how he did or didn't create reality. Please...

I don't think so. TIme travel is too risky anyway, besides I don't want to go into the "time paradoxes" argument

I hope you realize, lz, that I am you. From the future.

Twilight Zone music

But couldnt you travel back in time so fast that you reverse the rotation of earth, then going back in time? I could be wrong. Im not a scientest, lol.

Hey, I said it was my belief. I didn't state it as fact. Also, I believe God's plan is revealed in His Word and it tells us how He created the universe.

Watch this video - http://www.youtube.com/watch?v=mcBV-cXVWFw and then tell me that the universe is finite.

@Luigi78: Yeah the universe is huge. Don't worry, I've been looking into this stuff for a while. It's what led me to get saved since God was leading me.
Anyway I've led this off-topic. Just wanted to post my view.
edit: That was a beautiful vid btw. Thanks for sharing.

Oh yeah I time travel daily

@Outrunner: Hi, I am more on the side of the other posters, but thanks for sharing your point of view, I personally dont believe on religious gods, I'd rather reason science facts, but I respect everyone's belief as much as I like my reasoning to be respected by them. Besides a good philosopher always questions his own arguments and accepts the chance of being wrong as a chance of continue learning (I could be ignoring a fact which could prove me wrong and prove you right). So...

You said space is finite, then, what do you think exists out of its borders?, ... why? (Not meaning to argue, only to reason)

@Djungelurban: Interesting posts, all of them, thanks for sharing. I already took in count the time as only a measure, did you read my other posts? The problem with space on time travel dont make it physically impossible, only WAAAAYYYY harder.

But I must say I TOTALLY agree with you and Machu's view on parallel universes. Specially that part on which mankind may abuse this resources (as we have done with every other) to the point of destroying the space-time continuum. It maybe sounds crazy, but it also sounded crazy when people started worrying about the water, and you see what happens now.

Also, dont be so mean to Outrunner, as I said, we COULD be ignoring a fact which could prove us wrong and prove him right.

@Luigi78: Wonderful video man!

You sound a little bit like Einstein. In his writings he expressed frustration in his inability to remove time travel as a possibility. Of course, he was also frustrated with Quantum Physics. (Einstein: "I do not believe in a God who plays dice with the Universe", Bohr: "Stop telling God what to do with his Universe")

I am also Christian, but I do not see the conflict between time travel and Christianity. Upon examination, it becomes clear that the Universe has no "forward". Einstein said it best when he claimed that, "[time] is merely an illusion; albeit a very stubborn one." In fact, you can think of our existence as very pretty sculptures, with twists and turns and flow that gives each part of the sculpture a very alive feel to it.

For comparison, have you every won the solitaire game that comes with Windows? You know how the card bounces around but leaves behind its previously drawn images? That's how we look in four dimensional space. Yesterday, today, and tomorrow already exist. "Now" is a meaningless concept. Only the condition of cause and reaction shaping that model gives us the illusion of thought. That illusion is what provides any sort of awareness of time. Or for that matter, reality.

From a Christian perspective, one might initially despair at the idea that there is this fixed model of the universe. One might even believe that God has played a cosmic joke by fixing our lives into the sculpture of the Universe with us having no say in how they play out. Yet Quantum Physics gives another answer.

You see, the Universe is not quite as set in stone as it first appears. While the model of the Universe may already exist, how that model is shaped at points of cause and effect is actually... random. Or should I say, "probabilistic"? e.g. When we think of an event, say two objects colliding, we think that the outcome will always be a lot of destruction to follow Yet that isn't quite correct. The probability of destruction is extremely high, but there's also the chance that the objects could pass through each other, bounce harmlessly off, or otherwise do something that doesn't fit our logical view of the Universe.

The reason for this is that at the most basic level, the Universe is a bit unpredictable. We can only say that at our abstract, high level view, things seem to work in a consistent fashion. But that is an illusion as well. In reality, it is not possible to predict the outcome. So don't despair! It would appear that we may have "free will" (the ability to make our own choices) after all.

Back on the topic, I see no reason why an object extending in the fourth dimension can't bend back around. The problem seems to be in understanding how to make that happen. The geometry of the fourth dimension is confusing for humans. Primarily because it's just like the other 3, but with our baggage of perception added on.

Is it possible to slow something down in the fourth dimension and put it in reverse? Or to speed something past the speed of light (which takes infinite energy) and thus invert its course? These are questions that are difficult to answer. Especially once one better understands the geometry of the Universe. e.g. Is there really 4 light years between Earth/Sol and the nearest neighboring star? Well, not exactly. Go fast enough, and the distance can measure to barely a few feet! Keep accelerating and the universe will crowd you in and crush you. (Of course, to outside observers it will appear as if you got really huge.)

In short, there doesn't appear to be anything stopping "time travel". However, the ability to do so is likely to exceed human grasp until such a time as we can clearly understand and articulate the nature, shape, and geometry of space-time.

GASP!!!! That's impossible!!!

Dun dun dun! No, it's not impossible, it is the truth. Search your feelings; you know in your heart that it is the truth. Join me, lz, and togther we can rule this time period as...the same person!

@Phoenix: you know what this means, right? Total world domination with multiple mes running around!! Maybe time travel is not so impossible after all!

No, it's not impossible. I'm living proof of that, lz. i'm right here, standing in front of you-er, me.
