this theory is an idea from my side what if the 4th dimension is in real life?
What is the Fourth Dimension?
The Fourth Dimension is space that humans can't able see, but we can imagine, whereas in 3 Dimension we have 3 coordinates meaning the x-axis, y-axis, and z-axis.
We are 3D creatures, living in a 3D world but our eyes can show us only two dimensions(2D) whereas the x-axis and y-axis, The depth that we all think we can see is merely a trick that our brains have learned.
Before discussing 4th dimension, let us try to imagine 3rd dimension along with its coordinates.
I will help to visualize 3rd dimension, focusing on the above image let's imagine that you are standing on the x-axis, here we will take the x-axis as the road.
Let's take Traffic Signal is the center point in this image,
The Distance between the person and the traffic signal is 3 km. The car is traveling the z-axis, here we will consider it as another road which is perpendicular to the x-axis, the distance between the traffic signal and the car is 2 km and Finally, a bird at the top is flying at a height of 5 km from the ground level. If you think of this image as a box, you can able visualize the 3 dimensions. In 3 dimensions we have 3 coordinate values.
Now ask yourself, why in space they are using coordinates to go from one position to another? Because, to specify an object’s position in three-dimensional space or plot merely its direction, if the object’s distance is unknown. And even google maps, will use coordinates to point out the position of a place using latitude, longitude, and altitude, here altitude is the height from sea level.
Then what is the fourth dimension? In the Fourth Dimension, we will have four coordinates, In Addition to the x,y, and z axis there will another axis is ‘t’ called time.
4th dimension — (t,z,y,x) here, t — time
Four-dimensional space is a mathematical extension of the concept of three-dimensional.
If time is added in coordinates, Definitely the time needs to change every milli-seconds, In our world, everything and everyone is moving continuously from one place to another place every second.
Now, you imagine that the things you are seeing in this world for example flying bird are paused for one second, around you everything is in the same position, after that one second everything is started to move, now the current position of every people or thing around is changed their positions based on time.
So, We can come to one conclusion that every object moving based on time, looks like frames are moving in movies. Just imagine, if there is any option called backward, which can change the value of -‘T’(4th axis), we can view our past.
Still, I haven’t completed them, they are some proposed images of 4D by scientists.
The Above one is 4 Dimensional image, If this is a four dimension image, how it will relate to real life?
For that, I will give you one example to visualize better and easy to understand.
I hope most of us have used google meet, and we often faced the infinity mirror issue while projecting our screen.
This is an issue in Google Meet earlier, we will use this issue to understand the concept better, In the above image, the cursor position is changing it position in every frame, based on time right?
Here the frame is 2 Dimensional images if we replace those images with 3 Dimensional Cube (what you have image around you as 3 Dimensional in a unit second).
In your imagination, Take some 3 Dimension cubes in stacked them together one by one like
Compare this image with the google meet infinity mirror option, you will have a better idea to visualize. Then, the changing of time will be the fourth dimension.
Finally, Comparision of the Four Dimension image with the scenario, if you want to change the value of time, then the process of changing the 3d World from the present time to the given time, will be that image.
