So dimension is the angle you observe thing. In other words, dimension is the level of existence. It is like when you are in a car park, there are many levels like tall building. Level one, level two, level three and so on.
The person in level one can only see the cars in level one, but he cannot see the cars in level two. So dimension is just like the level of existence, like which level you are in when you are in a tall building, or in a car park where there are many levels.
So each time you look at the same object from a different angle, you will see a new dimension of the same object.
And because there are infinite ways of looking at a thing, there are endless dimensions. In other words, there are infinite numbers of dimensions, more than two billion dimensions.
So this is why if you look at the earth from earth, the earth appears to be flat, but if you are in outer space, the earth appears to be round.
If you observe earth in water, it is neither flat nor round.
So the earth has so many appearances, and each appearance is one dimension or one level of existence.
Each appearance is the angle you look at one object, and when you look at the same object from another angle, the same object appears to be different, which a new dimension appears.
So this is why if you move further away from an object, it looks smaller; if you move closer to it, the object appears larger.
Different appearances of one thing are different dimensions and there are infinite dimensions because there are infinite appearances of a thing if you look at it from endless angles.
Any question?
