ok, let's continue what are we talking about a few times ago...
it's about the gravity and we talk about what Space-Time is, and now i'm gonna explain it
Ok, i'm not a scientist nor a physician, so i'll just explain it with the easiest way as possible, and i'm sorry if it's wrong or else, you can correct me if im wrong.
Ok, simply, Space-Time is the 4th dimension....
What?, 4th?
What teacher thaught us at the school, stop at the third dimension, where we combine lenght, width, and height.
So, whats build the forth dimension?
Ok, the string theory explain that things...
The first dimension is one string, lets say that this is the "Widht", one line, without volume, without wide...
the second, is made up from combination between "Width" with "Length", it'll have a wide, 2 dimensional space.
The third is made up from the combination between the 2 dimensional space with "Height", if you close all the string there, it'll have a Volume, open it and you will have 6 main 2 dimensional space width
And the 4th?, what you add?
In spacial dimension, you can build a cube from another cube, so it'll contain other cube (?)
But, we talk about relativity theory...
The 4th is made up from 3D object and Time.
The question is, how?
Another simple explanation i'm gonna give you. i will give you some example
You have a 3 dimensional object on a table in front of you, let's say its a cube.
You start your stopwatch when the cube is right in the middle of the table, two second later, you move it 3Cm to the left, and 3 second later you move it 6Cm to the right...
what's that mean?
Simply, every single time is unique, when the stopwatch just started, it's right in the (0,0) coordinate, and 2 second later, it'll be in the (3,0) coordinate, and 3 second later, it'll be in the (-3,0) coordinate. simply, the times determine the possition of an object.
If that's the 4th dimension, what is the 5th?
You just need to combine it with Gravity-Electromagnetism, just like in the Kaluza-Kleinn Theory, but we arent gonna talk about that, so we'll just gonna stop at the 4th dimension part.
Now, the time is simply unique, everything will not be the same every time has changed, even in the milisecond level.
Back to the experiment from the first part, if there's two particle move along a parallel path, it'll collide, wheteher the first object collide the second, the second hit the first, they both hitting each other, or other combination of possibility
Now, the Newtonian gravity said that gravity is a force that emmited by a particle that pull other object . and Einstein have a different theory, the Gravity is a distortion in the space time that make the particle trajectory curved.
And, there's other theory talk about it, that gravity emmited by a hypothetical particle called as 'Graviton'
Well, it's hypothetical though, but at least they are trying to prove it's true...
Well, let's just said that every kind of theory, has it's own way of implementation
different case, different theory...
Well, let's stop this...
i'm getting tired now...
