Time Travel... soon?

Re: Time Travel... soon?

But if you went into the past wouldn't that have already happened, therefore nothing that you do could actually change the future?

That's why when you do something that alters the past it would automatically branch off from "our" reality and create a parallel universe where the changes you've made are possible.

Something like that has been done i believe and scientists are either planning on attempting or are already attempting on bringing back the mammoth using a process similar to that. It's basically cloning, just with an extinct animal.

Scientists are already planning on doing this with the Tazmanian Tiger. The animal became extinct do to over logging and destroying the habitiat. The habitat has now been returned to its natural state. It is basic cloning, but the animal must have a relative that can bear the animal through invetral fertilization. Cousins of the Tazmanian tiger have DNA close enough so they won't reject the animal. I would imagine an elephant could bear a Wooly Mammouth. They have already done this with some sort of extinct Llama that could be birthed by a camel. It makes sense if the natural habitat can once again sustain the species and undo a mistake made by humans.

Now that's something i'd like to see!

Seriously, i've always been fascinated by the wooly mammoth.

Well, if it creates a parallel universe, wouldn't that universe run parallel to the one that already exists? Meaning you DO exist at least in one universe but in the other one you don't. Might substantiate the multiverse theory as well, IMHO, if time travel truly can create parallel universes.

We can see the observed universe but there are many things in the universe that are not visibile to the eye like radio waves but yet we know radio waves do exist. A drastic change in the earths magnetic field would likely alter human consciousness that might enable one to see what was never seen before. Human consciousncess is probably an electromagnetic wave that enables very rapid information transfer between neurons in the brain and the manifestation of self awareness, critical thinking, free will etc. The electomagnetic wave within humans that is consciousness probably can interact with external low frequency radiation and the earths magnetic field. There is a theory in physics that says information can never be destroyed and is eternal so it may be possible to retrieve information fields and through an altered state of consciousness see events that are predistined to happen in the future.

Re: Time Travel... soon?

YP what's up. I understand the theory, I just don't agree with it. Here is why. Time is exact like math, when an occcurrence takes place it cannot be undone or unmade. To follow the logical progression of time travel is to accept the fact that past events can be undone. I don't accept that, not because I can't understand the logic of it, but rather as I understand time and the way it functions I can't accept the soundness of it. To me in order to accept time travel you must accept all manners of dimensional realities and parallel universes. The theory of time travel does not exist on its own but rather on the existence of other theory that are far more out there than the concept of time travel itself.

I understand.

I guess it's fair to say that I do believe in the possibility of alternate universes and time lines.

But, then again I'm also the guy that says life is probably possible without water in another planet or solar system and perhaps the only reason we don't think it is is because it's difficult to fathom life being born outside of the rules we live by.

I don't know if it would automatically make a parallel universe since if you went back in time to do something then what you do already happened. For example, if you go back in time to try to stop your grandfather from dying you might see that it's impossible to do so. I can't think of the words to explain everything, there are a few books that I have about quantum physics and time travel and all that, I'll try to find an explanation.

I think "paradox" is the word you're looking for. This would apply in the classical sense of time travel however what Mallett is saying and YP and I are advocating is that there are parallel universes and alternate timelines so you CAN alter the past but it would be the past in a fresh new timeline/universe.

YP: I wouldn't go so far as to say water may not be needed. Water or some form of it is the basic building block for life as we know it. I'm not going to jump off the deep end so to speak and claim that life can be born and sustained without H2O.

I'm interested in reading about this.

I've heard similar when regarding Hiro on the show "Heroes" going back to save a girl that dies. He goes back to alter her future, but eventually finds out that she has an aneurysm that could cause her to die at any time.

In the end, he discovers that even though he has the ability to travel through time, he doesn't have the power to change it. Time will do as it was destined.

I wouldn't expect you to.

My theory on it (and mind you this is without much study in it so I realize I could be extremely ignorant to it all) is that H20 is the building block of life on this earth because water is the dominant resource on this planet. We come from and are water.

Why (and I'm not extremely serious about it. mostly because of my ignorance on the subject.) couldn't another element do the same on another planet somewhere in the universe if it were the dominant resource?

YP, I think that carbon is the universal building block in the universe. Therefore as life exists on earth it also must exist to almost identical conditions elsewhere. To follow Big Bang is to accept that all planets, stars, and life is interrelated because they all come from a common beginning. So, water, would probably be just as needed as sunlight (starlight) to maintain life every where.

Yeah, the whole theory for the movie Jurassic Park came from this article out of omni magazine I think. The idea was taken from a scientists that explored this idea. It makes perfect sense to me, I just would like to see someone reproduce a T-Rex. That would impress me. Why, because there are some schools or thought that say dinosaurs never really existed or at least not in the way that we have been taught to believe. So if someone were to make a T-Rex that would be lay to rest some theories and belief systems.

There is no way to necessarily state that all life branches off from a tree that begins with the utilization of a certain compound. The big bang begins with a universal beginning, but that could have feasilbly headed in different directions once different ecosystems/chemical environments were created. That is to say that life could have begun in multiple locales, at (theoretically) different times with different (albeit similar) elements.. D2O/MRN-100 instead of H20.. Utlilizing silicon instead of carbon, phosphorous instead of nitrogen, sulfur instead of oxygen... etc.. all of these elements form chemical bonds with similar electronegative properties, etc., that could be interchangable in some instances... or perhaps elements were utilized that have yet to be discovered by human science.

The tendency to imagine water as the basis of all life is natural because it is the nature of our existence, but it bears little weight in terms of scientific exclusivity.

Re: Time Travel... soon?

He believes time travel to the past is a definite lock but time travel to the future is virtually impossible. Now once someone travels back in time and alters it, let's say you travel back and prevent your grandfather from dying. They you've instantaniously (sp) created a parallel universe. You can never go back to the original point in time that you came from because you've altered the past.

Of course that means the you from the current timestream no longer exists!

Pretty heavy stuff (80s California accent)

So you have created (singlehandedly?) a parallel universe (we'll call this universe number 2), in which you have placed yourself (for example, in the past), with no apparent way to return to the first universe. Given that you cannot exist in two universes simultaneously, what happens to "you", and more importantly, the primary universe, when you enter universe number 2?

For example, say you are a 35 year old car dealership owner with two kids, who goes back 10 years in time to prevent the war in Iraq. Once you enter the second dimension, what happens to that first universe? You have completely changed the reality of the present (in which you, and presumably - your children and your car dealership, the war in Iraq, and the casualties associated, in some capacity, do not exist). What becomes of the first universe? Once you pop through that time machine, do your children disappear? Do soldiers start rising out of their graves? Does your car dealership vaporize?

Can the original universe - not just speaking of yourself anymore - exist at all?

Human consciousncess is probably an electromagnetic wave that enables very rapid information transfer between neurons in the brain and the manifestation of self awareness, critical thinking, free will etc. The electomagnetic wave within humans that is consciousness probably can interact with external low frequency radiation and the earths magnetic field.

So what you are contending is that human thought is, in some way, supplied by this developed field of electromagnetic radiation that resonates from the Earth and all associated life?

I must say.. I can't buy that. I don't buy that human thought is in any way supplied, affected, or supplemented in this fashion. It's hard to say what exactly enables thought, although research shows that electrical stimulation and associated action potentials in specific neurons in the brain will elicit a specific memory. That is to say that it has been demonstrated, in surgery, that stimulating a specific neuron (for example) in the auditory center of the brain will elicit the same musical memory every single time electrical impluse is applied to that neuron. The associated neurotransmitter release and interneuronal interaction appears to make memory what it is.

I don't see how any sort of EM radiation from the Earth has been demonstrated to be involved in any way with human thought or memory.

There is a theory in physics that says information can never be destroyed and is eternal so it may be possible to retrieve information fields and through an altered state of consciousness see events that are predistined to happen in the future.

To stake this claim, you'd have to define what "information" is. By a purely neuroscientific definition, memory (and associated information) is nothing more than a learned neuronal response to electrical stimulation. I would argue that Alzheimer's patients, who have neurons destroyed with regularity, see a great deal of information go along with it. I don't see any basis for a claim of an external "electromagnetic hard drive", if you will, that stores everyone's neuronal responses to stimuli.

P.S.: Glad I found this thread.. LOL

Re: Time Travel... soon?

I wouldnt consider myself anywhere near an expert on the subject, bit I took Astronomy last semester and the professor simply that the best arguement against time travel is that you've never met anyone from the future.
