here is a thought experiment to keep yourself entertained.
Imagine how our world would look like if our reality was only two dimensional, instead of being three dimensional
I tried this thought experiment while driving to the office. Imagine what a road and the traffic would look like if things would exist only in two dimensions. It would mean that vehicles would not be able to travel next to each other - they would travel in a single file. How would a car look like in 2D ? That will be a hard question to answer. I can imagine two wheelers in 2D.
Next comes the question of what type of houses would we be living in ? I would say that we would have them in single file too. The rooms would be next to one another, something like what we see in stick figure drawings. How would be mark out fences in such a world.
I imagine that the world would look like a stick drawing. I can imagine thin people in that world, but how would the fat ones look like. Since there would be no 'sides' to expand to, they would grow in the front.
Here is another thought experiment to try
If our reality exists in 3D, but we are able to only perceive in 2D, what would our world look like So, think what if we could not perceive depth - only the XY axis.
There are no 'moral of the story' in these thought experiments - they are means to keep yourself entertained.
