When dimensions are mentioned we tend to think of portals throughother worlds, which will be only achievable in the future due to our limitedknowledge and use of the universe.
But that is not true, in fact observation ondimensions could lead us to the “Hyperspace” theory, which may be able to unifyall known laws of nature into one theory, the unification of all known physicalforces “the theory of everything”. But before getting to that, there is a needfor mastering the dimensions that we live in, and its characteristics. As weare experimenting and measuring our way within our dimensions we reach a limitwhich stops from going forward, higher dimensions, from this point on we canonly rely on math and our predications. Since we are prisoners of the thirddimension, and our minds are unable to imagine anything higher. One physicist who delights in teasing audiences about theproperties of higher dimensional universe is Peter Freund, a professor oftheoretical physics at University of Chicago’s renowned Enrico Fermi Institute.Freund states one of the reasons that higher dimensions were viewed skepticallywas that there was no way of measuring them and they also had no particularuse. But today scientists call our three-dimensional world too small todescribe the forces that govern our universe.
For centuries, scientistswondered why the four fundamental forces of nature are so different from eachother. Freund emphasizes that the laws of nature become simpler and moreelegant when expressed in higher dimensions, which is their natural home. TakeElectromagnetism for example, it includes electricity, magnetism, light itself,compared to another fundamental force like gravity which is quite different,but they are both necessary for our universe to exist, so there must be arelation between. Hyperspace was proposed a as new theory of gravity in whichlight could be explained as vibration in the fifth dimension. “Superstring theory”took this even further, it predicts a precise number of dimensions for spaceand time. Ten, this gives us the advantage to have enough room for all fourfundamental forces which are in their natural home and natural form.
Hyperspaceis based of how things change as we change the number of dimensions, it isclear an increase in dimensions is an increase in the quality we view theuniverse in, this can be demonstrated by comparing our self to a two-dimensionalcreature. For Hyperspace to be experimented, the ability to see higherdimensions is needed. When Freund was asked why we can’t see these higherdimensions, he responded with, because these higher dimensions have been “curledup” into tiny ball so small that they can no longer be detected, according toFreund the size of the of these curled dimensions is called Planck Length. Hebelieved dimensions get smaller as they increase, so we are tiny ball in atwo-dimensional world. There is still debate on this and its reasoning behindit. When searching up “Hyperspace” in a search engine it comes up withpictures that look liked traveling through stars or in a portal, which is areference from a sci-fi movie, this is due to the fact there is no pictures ofHyperspace or how it looks like, since we are unable to see. For a betterrealization of higher dimensions best way is to look back at lower dimensions.The world we live in contains 3 spatial dimensions (?3), this isillustrated by looking at anything.
Everything in this universe has a width,length and a depth. No single object lacks any of this dimensions in our world.Now what would happen if we lacked one of this in our universe, how differentwould it look like? This is the two-dimensional world, or Flatland, creaturesof this universe can’t even eat since a digestive system would cut them inhalf. These creatures are prisoned by their two-dimensional world, a jailin Flatland could be done by drawing a line around the criminal, no matterwhich way the criminal moves, he hits the impenetrable circle. If athree-dimensional was held in this jail, he could just walk over the line andthen he was free, in Flatland this would look like he disappeared for a secondand reappeared out of the jail. This is one of many the examples of our reachin the second dimension. Now imagine the powers of a fourth dimensional being,it would be like God-like powers in our perspective.
As we go up from zero dimension which is a dot to three dimensions,the world gets more complex, to a point where the universe has not enough roomfor its complexity, so there will be more than one universes. Multiverse, thishappens after fourth dimension which is time, most of the data on this part istheoretical and is based of predication. Common say there is no use for this,but this could be the only way to escape this universe, it is wise to say ourworld will end one day, so the only way to save intelligent life is to move into another universe, a parallel one.
How to travel to a different universe isstill a mystery, also there are really strange events that could happen in thisparallel universe, for example due to entropy, the number of different quantum volumes(all different ways particles can arrange) a person is 10 to the power of 1070,and let say an average human takes about 1m3 of space, now if thisparallel universe is far enough or even large enough for us to travel furtherthan 10 to the 1070 meters, we could see repetition of us. Identicalhumans but in a different universe. This is the power of Hyperspace At the end a there is this hypothesis that, a civilization withaccess to Hyperspace technology could rule all the dimensions below it andtravel to the edge of the universe. But since most of the data is theoreticaland not experimental, not a lot of research is going through this subject, andis commonly known as a reference from Sci-Fi comic books or movies. But itmight help us find the foundation of the forces that govern our universe and anew era of civilization This was all from part 1 and 2 of a book named “Hyperspace” by Michio Kaku which I read during the pastmonths.
