Be nice to be able to make an apple pie. Heh. It's easy to speak of breaking or bending space but we're no nearer to an understanding of what the underlying structure of space is than when we first envisioned gravitational fields as a flat plane deformed by objects placed on it, heck we don’t even know if it can be broken. Perhaps it would be better not to though considering we might not be able to put it back together again...

Nope, I've heard it all before from a variety of sources, and some of it seemed to be based on a rather bad movie. ;)

phawksy;3825330Actually, they can teleport the cancerous cells out of your body nowadays.

...

Well, it's either have your *insert cancer-afflicted piece of anatomy here* rot to pieces or have a big hole in spacetime there, your decision...

Wow, I wonder what hospital does that now a days. Wish they told me that before I signed up for the bone marrow transplant.[/sarcasm]

In other words, I need to see some proof.[/SIZE]

Er, no they can't. At all.

phawksy;3825282Time travel is impossible in this universe.

Is it really sensible to use an outright declaration in theoretical physics?

However, I theorize that every instant that passes in this universe creates a new universe in the universe of universes ("megaverse"). By that, I mean that this realm is duplicated every instant, where the duplicates are in suspended animation ("paused").

So you propose that time breaks our current understanding that it is impossible to create matter? An interesting proposition, but improbable to me.

By breaking free of this realm, i.e., punching through the "bubble" into space outside of space, you could *theoretically* pass into any of the duplicate universes, thus traveling in time, more or less.

Except I find it difficult to comprehend how you can move through something that changes every instant, without the use of time travel (Or, more accurately, suspension of time)

So, I think that to pass between universes, you would have to be unconscious, i.e., not able to witness the change taking place.

Until someone proves that consciousness is the root of all existence, I refuse to believe that simply being unconscious will solve the above issue I stated.

However, you could not travel into the future; as cliched as it sounds, "the future is not written yet".

How do you know? Have you seen it? ;)

For the future to be written before it happens, the universe would have to be on a linear path through time where EVERYTHING was predetermined.

Funnily enough, that's called determinism, and I find it a lot more logical than assuming that there are entirely random phenomena in the universe. Perhaps it's my programmer-oriented brain, but a universe seems a lot more logical than people give it credit for.

For example; I could choose either to turn the sound up a notch on the stereo, or not to; by turning up the stereo, my memories and those of everything within earshot would be dramatically changed than if I chose not to turn the stereo up. So, there would have to be an infinite amount of future universes, one where I turned up the stereo and one where I didn't. That's only two universes; but add in all the other variables of things in the universe that could change. It wouldn't be practical for that to happen.

Well, it's a fairly well-known theory that both things do happen, and split off into infinite universes.

My take on this: You're assuming what doesn't make sense to me: That time itself does not fracture, when it itself is a "time dimension". It makes more sense to me that this non-spatial dimension can be navigated instead, in a method analogous to a network of paths containing all the quantum differences (For a Sci-Fi example, see the Star Trek TNG episode "Parallels", though the plot is somewhat far-fetched). It would not make sense that a universe splits on two dimensions simultaneously for the same effect, unless there is a large area of it that we have missed - Itself being likely, but fitting this would be unlikely.

We all know that due to recent studies, it is confirmed to be impossible for anything in this universe to travel faster than light.

We all knew due to recent studies that the Earth was the centre of The Universe. Recent studies also indicate that the speed of light itself has changed over time, so I wouldn't be so sure.

We also know that traveling as fast as light in this universe is equally impossible, because you need an amount of energy roughly twice as much as there was at the beginning of the universe, i.e., the amount of energy there is in the universe at any given time right now.

Well, light manages, but it doesn't use anything close to infinite energy.

By breaking free of this realm, into the space outside of space, the universe holding within it all other universes, the megaverse, you could theoretically move faster than light, then reenter this universe at a predetermined location.

Having never seen the space outside of space, I couldn't tell you it existed, but you seem to be describing a theoretical form of travel known as "space folding", which also gives rise to the idea of wormholes. The idea being that space fabric could be folded in order to travel from A to B, goodness knows what that does to the surrounding matter in both locations.

Studies have shown that it is possible to teleport atoms instantly from one point in space to another. By moving entire craft, people, or even planets, you could instantly move from one point in the universe to another. Information about the object to be teleported is scanned, retrieved, and projected into anonymous matter to create a perfect replica of said object. It's similar to a fax machine, as depicted by the illustration in the article below.

I've heard of the physics behind this, but I do not think that people should be put through it. We know nothing about what drives consciousness, and a breakdown of matter doesn't sound like the ideal way to preserve it. Similarly, anything using or generating electrical power is probably dangerous as the circuits degrade. You're welcome to try it first, but yeah. :uhm:

phawksy;3825282First off, I would like to let everyone here know that I appreciate you all, but the topics y'all make cause even my genius brain to grind and eventually hurt. This is furthered by my astigmatism in the left eye, which, in itself, is excruciatingly painful. Secondly, I want to share some of that pain with you. In my own form. :devil: }> Time travel Time travel is impossible in this universe. However, I theorize that every instant that passes in this universe creates a new universe in the universe of universes ("megaverse"). By that, I mean that this realm is duplicated every instant, where the duplicates are in suspended animation ("paused"). By breaking free of this realm, i.e., punching through the "bubble" into space outside of space, you could *theoretically* pass into any of the duplicate universes, thus traveling in time, more or less. The primary spark that set this idea aflame was the Stephen King B-movie entitled The Langoliers. In that movie, an airliner full of passengers passed through a hole in the space-time fabric into an alternate dimension where time passed very quickly and everything was utterly empty; food was stale, drinks were flat, matches wouldn't light, sound wouldn't carry, and no conscious things (animals, basically) were present. The only passengers that entered this realm were the ones that were asleep when the realm transition occurred. Those that were awake simply ceased to exist anymore. In the alternate universe, creatures called Langoliers destroyed the entire space-time fabric, and the aircraft flew back through the hole into the future, where they snapped back into the current realm once time caught up with them. So, I think that to pass between universes, you would have to be unconscious, i.e., not able to witness the change taking place.

Faster than light travel We all know that due to recent studies, it is confirmed to be impossible for anything in this universe to travel faster than light. It would take an infinite amount of energy to move an infinitely small particle an infinitely small fraction of a mile per hour faster than lightspeed. We also know that traveling as fast as light in this universe is equally impossible, because you need an amount of energy roughly twice as much as there was at the beginning of the universe, i.e., the amount of energy there is in the universe at any given time right now. However, I have two theories. 1. Hyperspace- By breaking free of this realm, into the space outside of space, the universe holding within it all other universes, the megaverse, you could theoretically move faster than light, then reenter this universe at a predetermined location. 2. Quantum teleportation- Studies have shown that it is possible to teleport atoms instantly from one point in space to another. By moving entire craft, people, or even planets, you could instantly move from one point in the universe to another. Information about the object to be teleported is scanned, retrieved, and projected into anonymous matter to create a perfect replica of said object. It's similar to a fax machine, as depicted by the illustration in the article below. Teleportation IBM article. I HOP TAT UR BRANE HURTZ LIEK MEIN, U COMIEZ!!!!!!!!!!!!! (Translation: I hope that your brain hurts like mine, you communists!)

First off, the topic of Time Travel is one of the most heated topics on the planet. Everyone believes in something different. Although I believe the goverment is hiding technology from us, *Cough* Area 51 *Cough, Alot of of other people believe that too. One part of that technology is most likely a Time Travel device, which is one serious piece of technology. I also support the theory of Stargates and wormholes, and I believe we'll have them much sooner in the future than we spectulate. Second, Light Travel: The goverment definitely is hiding this technology from us. If we learned on our own to travel faster than the speed of sound, than we definitely figured out, or are on our own to finding how to travel faster than the speed of light. All the shows you see, like Star Trek, Stargate, Andromeda, they all seem to have Hyperspace Engines, which in other words stand for, ''Light Speed'' Engines. I definitely believe we have these on our planet, hidden somewhere. Now to my favorite topic, Quantum Teleportation. Wow, well just think of the possibilities of teleportation? I mean you all may think this would be a great technological advancement, and It would be, but just think what it would be used for if It fell into enemy hands. They could use it teleport onto US soil and plan bombings, and even get into top secret military bases and steal confidental information. Imagine what that would end in? Chaos, complete chaos is the answer. We would be destroying our own race faster than you can say ''Terrorism has struck the United States of America.'' I'll let you all think about that. I agree that it would a great technological advancement, but think of the consequences if It fell into enemy hands.

Then you have no understanding of such things. Faster thn sound travel is possible, faster than light travel is NOT. There's a reason such shows are classed as science fiction. Besides, why would any government want to hide the fact that it has the technology to do such things? Anything like that would make it lots and lots of money. What makes you think the technology exists, other than an obvious deap seated mistrust for any big institution?

Syyrax;3831590Now to my favorite topic, Quantum Teleportation.

Oh dear...

[quote=Syyrax;3831590]Wow, well just think of the possibilities of teleportation?

Setting aside the fact that this is also impossible, don't you think techology like that, if it existed, would be far too expensive and power demanding for any terrorist to use?

My apologies for being so blunt (Honest), but I find that to be completely erroneous. I don't know if your government, my government or any other government is hiding any technology of this nature, but the speed of sound and the speed of light are two very different things. You make this claim as if the speed of sound were as easy to break, or as though sound and light were the same thing. All that is publicly (To give potential leeway to governmental conspiracy) about faster-than-light travel is rooted in theory, myth, and particle names. We have names for theoretical particles which break the speed of light, but I know of no experiments which have unearthed them, let alone broke them.

We can slow down light using refraction, even to ridiculously slow speeds - We can break those, I think one experiment put the speed of light down to 30mph, but I doubt they put a car through it to see if it went back in time, and I doubt just as much that it would have done so.

Assuming that to be the case, the speed of light is not necessarily the fundamental barrier for time travel. Though I would say that with our present understanding, the constant for the speed of light is far more likely to be the threshold.

Now to my favorite topic, Quantum Teleportation. Wow, well just think of the possibilities of teleportation? I mean you all may think this would be a great technological advancement, and It would be, but just think what it would be used for if It fell into enemy hands. They could use it teleport onto US soil and plan bombings, and even get into top secret military bases and steal confidental information. Imagine what that would end in?

I agree that it would a great technological advancement, but think of the consequences if It fell into enemy hands.

Nothing I have read has ever shown free teleportation (or copying of atomic data) into free space. All the experiments I have seen involved a decoder at the other end. Again with the assumption that I recall correctly, this would mean that if you didn't want people teleporting in and out of your building, you didn't put a teleporter in there. That would seem to solve the problem. Once we get to that level, and if we find a way to teleport into free space, I suspect we also will have the ability to scramble anything that tries to pass through, and that'll definitely have issues for anything that arrives from the other end.

Remember, these are my opinions. And about the teleportation, I was just saying that IF terrorists happened to get the technology. Also, I agree with you sheep, but I was talking about in the beginning of that technology being released. The people wouldn't think of it getting into enemy hands, they would be more focused on figuring out the ways it can be used. And about the speed of sound and speed of light, I wasn't exactly trying to say they were the same. I was saying that If we can break the speed of sound, there's a possibility that we can break the speed of light in the future. I think I wrote that wrong, my mistake.

Syyrax;3831758...there's a possibility that we can break the speed of light in the future.[/quote] No. You can't. Again, two different things. [QUOTE=Wikipedia] Faster-Than-Light travel or communication is prohibited by Einstein's theory of relativity. According to Einstein's theory of special relativity, what we measure as the speed of light in a vacuum is actually the fundamental physical constant c. This means that all observers, regardless of their relative velocity, will always measure zero-mass particles such as photons traveling at c in a vacuum. This result means that measurements of time and velocity in different frames are no longer related simply by constant shifts, but are instead related by Poincaré transformations. These transformations have important implications:
  • Matter becomes more massive as it accelerates, and at the speed of light, an object would have infinite mass.
  • To accelerate an object of non-zero rest mass to c would require infinite time with any finite acceleration, or infinite acceleration for a finite amount of time.
  • Either way, such acceleration requires infinite energy. Going beyond the speed of light in a homogeneous space would hence require more than infinite energy, which is not a sensible notion.
  • Observers with relative motion will disagree which occurs first of any two events that are separated by a space-like interval. In other words, any travel that is faster-than-light in any inertial frame of reference will be traveling backwards in time in any other, equally valid, frames of reference.

Alright, alright, one thing that all you Einstein-thumpers need to get drilled through your skulls;

Newton's laws governed the entire Universe until Einstein came by and burned down the courthouse, so to speak, and built his own right over the ashes. It's only a matter of time before somebody else waltzes by with the Molotov Cocktail of physics and torches ol' Einstein's place.

Seeing as to how Newton's laws were established in 1687 and Einstein's in 1921, a difference of 234 years, so I'm guessing that (if the trend continues) our next revolutionizing physicist should burn the laws of physics around 2155 or so. Which, like most of you here today, is a bit longer than my current life expectancy.

Goodbye, and goodnight. My head is hurting and you f***ers aren't helping the matter. So shove your keyboard/mouse where you will and allow me some peace and quiet without the constant bombardment of 5+ syllable words.

...

I'm just kidding. About the headache part, at least. :lol: F*** THE COMMIES, B****ES!
