Will we soon be able to travel between dimensions with the advances in Physics and String Theory?

According to string theory, the extra dimensions would be infinitesimally small, so we could not travel into them.  However, there are other theories (i.e. Heim Theory) that have dimensions that we could travel through.

you should read more into string theroy and the M theory.  they are both very interesting.  it is hard to wrap your mind around but  this is just one universe that goes along a membrane of universes that goes on infinetely.  the science channel often has show that explin all this much better and they make it pretty easy to understand.

Good question, probably travel through time and space.  Remember that boundary conditions are important for string behavior. Strings can be open, with ends that travel at the speed of light, or closed, with their ends joined in a ring.\n   One of the particle states of a closed string has zero mass and two units of spin, the same mass and spin as a graviton, the particle that is supposed to be the carrier of the gravitational force. Now that you have this information, take it and run with it.  Let me know what you find out.  Just kidding, good luck finding a solution.

Oh my, have you opened up a can of nightmarish confusion.\n\nYou are referring to String Theory, and it is way too complicated to describe here.  Here is an exerpt from an article on wikipedia of String Theory that describes these extra dimensions:\n\nOne intriguing feature of string theory is that it predicts the number of dimensions which the universe should possess. Nothing in Maxwell's theory of electromagnetism or Einstein's theory of relativity makes this kind of prediction; these theories require physicists to insert the number of dimensions "by hand". The first person to add a fifth dimension to Einstein's four was the German mathematician Theodor Kaluza in 1919. The reason for the unobservability of the fifth dimension (its compactness) was suggested by the Swedish physicist Oskar Klein in 1926.\n\nInstead, string theory allows one to compute the number of spacetime dimensions from first principles. Technically, this happens because for a different number of dimensions, the theory has a gauge anomaly. This can be understood by noting that in a consistent theory which includes a photon (technically, a particle carring a force related to an unbroken gauge symmetry), it must be massless. The mass of the photon which is predicted by string theory depends on the energy of the string mode which represents the photon. This energy includes a contribution from Casimir effect, namely from quantum fluctuations in the string. The size of this contribution depends on the number of dimensions since for a larger number of dimensions, there are more possible fluctuations in the string position. Therefor, the photon will be massless - and the theory consistent - only for a particular number of dimensions.\n\nThe only problem is that when the calculation is done, the universe's dimensionality is not four as one may expect (three axes of space and one of time), but twenty-six. More precisely, bosonic string theories are 26-dimensional, while superstring and M-theories turn out to involve 10 or 11 dimensions. In bosonic string theories, the 26 dimensions come from the Polyakov equation (see technical details in the preprint "Quantum Geometry of Bosonic Strings - Revisited"). However, these results appear to contradict the observed four dimensional space-time.\n\n \nCalabi-Yau manifold (3D projection)Two different ways have been proposed to solve this apparent contradiction. The first is to compactify the extra dimensions; i.e., the 6 or 7 extra dimensions are so small as to be undetectable in our phenomenal experience. The 6-dimensional model's resolution is achieved with Calabi-Yau spaces. In 7 dimensions, they are termed G2 manifolds. Essentially these extra dimensions are compactified by causing them to loop back upon themselves.\n\nA standard analogy for this is to consider multidimensional space as a garden hose. If the hose is viewed from a sufficient distance, it appears to have only one dimension, its length. Indeed, think of a ball small enough to enter the hose but not too small. Throwing such a ball inside the hose, the ball would move more or less in one dimension; in any experiment we make by throwing such balls in the hose, the only important movement will be one-dimensional, that is, along the hose. However, as one approaches the hose, one discovers that it contains a second dimension, its circumference. Thus, a ant crawling inside it would move in two dimensions (and a fly flying in it would move in three dimensions). This "extra dimension" is only visible within a relatively close range to the hose, or if one "throws in" small enough objects. Similarly, the extra compact dimensions are only visible at extremely small distances, or by experimenting with particles with extremely small wave lengths (of the order of the compact dimension's radius), which in quantum mechanics means very high energies (see wave-particle duality).\n\nAnother possibility is that we

this is sort of trival, dimensions can be thought of as derivatives, and you can take a formula and make any number of derivatives of the original derivatives and still end up with a line that bends, indicating no limit to the number of dimensions we can really conceive..   \nModern string theory is a bunch of hoo haa,   such a sub-atomic idea makes no sense, the reality we know could not have order if there were "strings".  "strings" have no way of organizing themselves into different sub-atomic particles, the universe would just be a bunch of "strings"

That's the problem. You can't go beyond the speed of light. It is the cosmic speed limit. But if you could, then you'll be able to travel through time, past and future.

The focus in the 21st century for the forefront of physics is understand the connection between General Relativity and Quantum Mechanics. No question about this. The results could be a string theory, or loop gravity, or something completely different.\n\nAlso up there I think is a better understanding of a property we all know and love: mass. There is a search for the Higgs Boson. We need to find it and study it. Or, if it can't be observed try and determine what that means.\n\nOther challengs include being able to use the EPR phenomena of quantum entanglement to produce the first prototypes of an actual encrypted signal over a reasonable distance.\n\nNanotechnology is another challengs, in how to work those little parts into ways that form mini-computers, and also in ways that allow for various medical uses.

Yes of course...\nIts very interesting question from you... But I can give one best reference to you if you wish to know more about space/ dimension/time etc without any mathematical hectic equations...\n\n"A breif history of Time" by Stephen hawkings... excellent book on above concepts...

Additional info: I've talked to Holger Bech, one of the three founding fathers and Danish, and not even he believes in the theory. Basically, this is due to the String Theory postulating the existence of 9 dimensions. We can see that this is pretty far from the case, with there only being 3 physical dimensions and time, equaling 4. Furthermore, S.T. postulates that almost 300 of a specific grouping of particles exist. Experimental testing estimates that only 16 exist.

It's amazing isn't it?! It's so beyond our technology to fully test the theory though. I do however believe in parallel universes because math proves that you can have more dimensions beyond what we possess. Have to be able to open your mind to understand, ya know?

String theory is still quite new in the world of physics, but it has drawn tremendous attention to all physicists around the world. \nFor the last 80 years or so physicists have been trying to find a theory that will combine the theories of quantum mechanics and general relativity. These two theories describe everything in the universe. General relativity does this on the scale of the very large e.g. planets, galaxies and so on. When it comes to subatomic scale, like protons, quarks etc. general relativity breaks down. This is where quantum mechanics is very accurate, but quantum mechanics does not work when applied to the very large objects. \nGeneral relativity basically deals with gravity and has a calm feeling to it. The predictions it makes is always sort of neat and precise.\nQuantum mechanics on the other hand deals with the uncertainty principal and has a very chaotic feel to it.\n\n\nString theory is what physicisits hope and believe might be the theory combines these two super theories. String theory predicts that every particle (even quarks) are made up of much, much smaller particles called strings. They are not really particles, they are actually vibrating strands of energy. Each of these strands vibrate in a different way. \n\nThe mathematics behind string theory works so well that many believe string theory has to be true, but unfortunately there is currently no way to prove string theory with experiment. If string theory is true, then some of our notions of the universe will have to change dramatically. We will have to accept that we actually live in an 11-dimensional universe.

It hasn't been completely accepted, but it is widely believed to be the correct direction to go.  They are still trimming the fat, and many of the theories will never be tested as we can not experience some things that occur in the extra dimensions that we can not see, according to string theory.  (Theory is not accepted as fact, its a theory)

Very simply put, string theory (now most often called "M" theory) is an attempt to unite quantum physics with relativity; we hope that by doing so we can develop a set of equations that will tie together the four fundamental forces of nature. The direct relationship of three of those forces have been linked, but gravity so far remains the "outsider."

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles) that are the basis of the Standard Model of particle physics. For this reason, string theories are able to avoid problems associated with the presence of pointlike particles in a physical theory. Studies of string theories have revealed that they require not just strings, but also higher-dimensional objects.\n\nThe basic idea is that the fundamental constituents of reality are strings of energy of the Planck length (about 10-35 m) which vibrate at resonant specific frequencies[1]. Another key claim of the theory is that no measurable differences can be detected between strings that wrap around dimensions smaller than themselves and those that move along larger dimensions (i.e., physical processes in a dimension of size R match those in a dimension of size 1/R). Singularities are avoided because the observed consequences of "big crunches" never reach zero size. In fact, should the universe begin a "big crunch" sort of process, string theory dictates that the universe could never be smaller than the size of a string, at which point it would actually begin expanding.\n\nInterest in string theory is driven largely by the hope that it will prove to be a theory of everything. It is a possible solution of the quantum gravity problem, and in addition to gravity it can naturally describe interactions similar to electromagnetism and the other forces of nature. Superstring theories include fermions, the building blocks of matter, and incorporate supersymmetry. It is not yet known whether string theory will be able to describe a universe with the precise collection of forces and matter that is observed, nor how much freedom to choose those details that the theory will allow. String theory as a whole has not yet made falsifiable predictions that would allow it to be experimentally tested, though various special corners of the theory are accessible to planned observations and experiments. Hence critics of string theory occasionally remark that the theory "... is not even wrong," quoting a quip attributed to Wolfgang Pauli.\n\nWork on string theory has led to advances in mathematics, mainly in algebraic geometry. String theory has also led to other theories, supersymmetric gauge theories, which will be tested at the new Large Hadron Collider experiment.

String Theory is only a theory of description of elementary particles based on one-dimensional curves, or "strings," instead of point particles, given by from some theoretical Physicist.\nThe energy-scale at which the stringlike properties would become evident is so high that it is currently unclear how any of the forms of the theory could be tested.\nSo it has not been tested yet and I think it will remain a theory not reality in near future.

Third dimensional particles (this includes light and electronic data streams) must move through Time (4th Dimension) in a single straight line.  Though you may make them go any direction at any speed within the three dimensions of our reality, time is constant.  The only way to move something in a different direction along Time you would have to get these particles into that dimension and move them along a 5th.\nSo it's just not possible at our current understanding of physics

Do some research on a gentleman by the name of Kip Thorne, and he will explain about the possibility of time travel through use of a wormhole. Think of a universe as a sheet of paper. bend it so that one end touches the other, the wormhole would connect the two opposite ends of the paper by the shorter distance between the ends of the paper, you follow? This is what a wormhole does. Now according to Einstein's Theory of Relativity, time will slow as you move closer to the speed of light, and will stop entirely once you reach that speed. SO, if we have two ends of a wormhole, and send one off into deep space at light speed, for several years, then when it returns in, let's say, the year 2020, then we would be able to jump in the end of the wormhole that stayed here and come out the other end in the year 2006. Time travel into the past would be highly unlikely due to the fact that in the past (like prehistoric times), neither you nor the time machine existed. Mr. Thorne also has several possiblities when entering a wormhole. 1) soon as you enter one end of a wormhole, you instantly pop out the other. 2) there is a slight delay between the time you enter and the time you exit. 3) you exit the wormhole before you even enter it. Wild huh? the only problem is that wormholes are unpredictable, they open and close all the time, so one may get crushed in it while attempting to travel to the past. However, they have recently found a way of transporting information FASTER than the speed of light. Accordind to Einstein's ToR, that would cause a reverse in time...so who knows...?
