![]() ![]() Some scientists believe that the multiverse has only 10 dimensions while others put that number at 11. The ninth dimension lays bare all the universal laws of physics and the conditions of each individual universe. This dimension is a plane of all the possible pasts and futures for each universe, stretching infinitely. That is, they were not born from the Big Bang. The seventh dimension is the start of this, where we encounter new universes which have a different beginning from ours. In the seventh dimension up through the ninth, we currently have the possibility of new universes with new physical forces of nature and different laws of gravity and light. The sixth dimension is a whole plane of new worlds that would let you see all possible futures, presents, and pasts with, again, the same start as our universe. In the fifth dimension there would be a new world that would let us see the similarities and differences between our world and this new one, existing in the same position and having the same start as our planet, i.e. The dimensions here on out really deal with possibilities. These dimensions are curled in on themselves in a process known as compactification. These are imperceptible to us, researchers think, because they exist on a subatomic level. The only thing that can move across dimensions, like time, is gravity.įrom here on we start to look at the higher dimensions. Time is relative, okay? It can stretch and it can squeeze, but… it can’t run backwards. Remember how the third dimension is space without time? Well now we officially have space time. Time helps plot an object’s location in the universe and also adds a way for the third dimension to change. The fourth dimension is not a spacial one but it consists instead of time. You can think of this dimension as space without time. It contains volume and the ability to obtain cross sections from objects. This is the dimension in which we see the world. ![]() Imagine any flat figure, like a triangle. There is no depth and no height, only a width. Here, I try to simplify the ten dimensions of string theory.Ī line linking two points. This splitting apart of a universe bubble is one possibility of what might have resulted in the Big Bang. Yes, the multiverse, where universes are bubbles that sometimes come together or split apart. Physicists think but cannot yet prove that there are up to 11 dimensions in the multiverse. Actually, string theory, which tries to reconcile relativity with quantum mechanics (the laws of the very big with the very small), only functions if we believe there are much more than the four dimensions we’re used to. We are those fish and those higher dimensions are the new environments we can’t see. This is the scenario physicists think we’re in. Nevertheless, there is a completely new environment outside of your line of sight - one where animals don’t need water to breathe and flowers bloom in a far more arid world. You live your life thinking that this underwater world is all there is because it’s all that you can see. The sunlight comes in, dimmer and refracted, through the water. String theory has already had a big impact on pure mathematics, cosmology (the study of the universe), and the way particle physicists interpret experiments, by suggesting new approaches and possibilities to explore.What if you were living in a pond? You are a fish with eyes on either side of your head and all you are familiar with is the underwater world of sediment and vegetation and other fish swimming next to you. Practitioners are optimistic that string theory will eventually make predictions that can be experimentally tested. The study of string theory has also led to the concept of supersymmetry, which would double the number of elementary particles. String theory also requires six or seven extra dimensions of space, and it contains ways of relating large extra dimensions to small ones. String theory not only embraces gravity but requires it. Previous attempts to unify physics have had trouble incorporating gravity with the other forces. It has since developed into something much more ambitious: an approach to the construction of a complete unified theory of all fundamental particles and forces. String theory originated as an attempt to describe the interactions of particles such as protons. What we perceive as particles are actually vibrations in loops of string, each with its own characteristic frequency. String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. ![]()
