Question

What are dimensions , open up a complete research profile on it , dealing with every consequences possible ?

Answer 1

Defination: Quantities that allow us to specify the position of a particle or visualize it.
In string theory, spacetime is 26-dimensional or 10-dimensional (As per bosonic string theory and superstring theory respectively) and in M-theory it is 11-dimensional.

Zeroth dimension ,a point, a single dot with no practical measures.
Many points come in a specific straight configuration to form a line, the 1st dimension.
Many lines come in a specific straight configuration to form a plane, the 2nd dimension.
Same with the 3rd dimension, many planes come together to form a object.
Now, many planes come together to form a world line, the 4th dimension, Time.
Say, there is a world line(commonly called the time line), its just like a 1d line on a plane, so what’s the space of the rest of the plane, possibilities. There are infinite number of points orthogonal or at any angle to the world line, so are possibilities. This is the 5th dimension. I will like to elaborate this dimension. In the 5th dimension, there are 2 most accepted theories, the MWI(Many Worlds Interpretation) and the Copenhagen Theory.
When Quantum Mechanics was developed, the Mathematics was developed at the base. Now, the equations yielded wierd results.
To understanding the implications, and to cover them in form of a physical theory, quantum physicists split into two groups which had different ideologies.
One of them was the Scientist Group which worked at the Copenhagen University.
I just checked at Wikipedia: Neils Bohr and Werner Heisenberg were the key people in this group, and they were associated with Copenhagen University at the time. So this method of interpreting different aspects of Quantum Mechanics is called the Copenhagen Interpretation
In the Copenhagen Interpretation, the quantum properties are all covered in a mathematical form called the Wave function.
For example, consider the Quantum Superposition.
In our example, let's take an electron which is in a Superposition of two spin states: +½ and -½
This can be represented by a wave function.
Now, according to Copenhagen Interpretation, when the electron is observed, a wave function collapse occurs, and the electron comes into one of the two states in reality.
In Many Worlds Interpretation, when the electron is observed, the Universe splits into two. In one universe, the electron collapses into +½ and in the other universe, it collapses into -½.
In this way, there are all the universes with all the different possibilities
This was the basic difference between the two ideologies. The Copenhagen Interpretation assumes a _random_ collapse, while the MWI assumes both types of collapses in different universes .

Now, if we can change our version of the universe we would be 6th dimensional beings. The presence of different versions of the universes is like planes in a infinite space. There are a total of approximately 10500 universes currently. This is the 6th dimension.

The 1st dimension is like the 4nd dimension, a simple line and a world line. The 2nd dimension is like the 5th dimension a simple plane and a plane of possibilities. The 3rd dimension is like the 6th dimension, a simple solid and a solid of all the possibilities and different version of the universe.

I can explain only till the 6th dimension as for the next for dimensions, either I have a blurred idea or don’t know much about to explain it. So, I stop the description of dimensions here.
