# ENT601-50. Week 7. The 10 dimensions are?

I am reading a book titled "Hyperspace", by Michio Kaku. “A Scientific Odyssey Through Parallel Universes, Time Warps, And The 10th Dimension.”

For my last post for this class, I'm going to briefly explain each dimension. These different dimensions, are what governs the universe. I believe most people are familiar with the first 4 dimensions, but the 6th-10 dimensions couldn't exist without string theory, or string theory couldn't exist without these later 6 dimensions. It is debatable that this includes the 4th dimension too.

I'll go ahead and begin with the dimensions we are all most familiar with. The 1st dimension is length, or the x-axis. A straight line is an example of something one-dimensional, because it can only be measured in length. The 2nd dimension is height, or the y-axis. A square is a 2-dimensional object. The 3rd dimension is depth, also known as the z-axis. A cube is the best example, with length, width, and height, or depth. The 4th dimension has been accepted among some, but is still considered a theory to others. The first 3 dimensions are the dimensions that have been scientifically proven.

The 4th dimension is time. We need to know an object's position in time in order to plot its position in the universe. The 5th and 6th dimensions rely on superstring theory, where it begins the idea of possible worlds, and not just ours, existing. In the 5th dimension, we would see a world slightly different from earth. In the 6th dimension, there is a plane that we can see of the possible worlds. In the 5th and 6th dimension, we can time travel.

In the 7th, 8th, and 9th dimensions, the possibility of multiple universes open up. In the 7th dimension, it adds to the 6th dimension of possible worlds, but all worlds start with *different *conditions. Everything is different from the beginning of time here. The 8th dimension includes this plane of possible worlds, with the start of different conditions, and each branching out *infinitely*. The 9th dimension includes all possible worlds, all of these starting conditions, and the laws of physics. The 10th dimension is infinite possibilities. Everything possible and imaginable exists in this dimension. Beyond this, nothing can go beyond a mortal's limited mind. The 6th of these additional dimensions is necessary for string theory to possibly be supported by nature. We cannot perceive some of these dimensions, but it doesn't necessarily mean that they don't exist.
