Spiritual Physics

I came back to where the ruby was and tried to change its shape by squeezing for a prolonged period. It worked. Although it took me more than half an hour to an unnoticeable change of less than a millimeter. After that, I tried to make one side very sharp so I could make a knife and see if I could cut through the shirt.

I started working on that but it was way harder than I thought. After all, there was no stone nearby to use as a sharpener. Then, I did what any sane human would do: make a new branch of physics from the ground to facilitate the sharpening process.

I knew that the physics in this realm were wiggly but surely enough there had to be spiritual laws, and what I need now is to try and deduce them by running experiments using the only two- sorry I mean three items I have: my clothes, the ruby, and my body.

I tried to lightly hit my hand with the ruby but I didn't feel any pain. I increased the power of the hit with each blow until it started to slightly hurt when I did it with all my might. I guess spirits do feel pain but on a way lesser scale.

Is that why the dark figure didn't feel anything and was fast enough to make it look like teleportation?

That would also mean that there is a way to interact with humans in the material world. Phew, so there is hope huh?

I continued with my experiments by wrapping my arm up with 50m worth of the shirt but my hands didn't get blue, that's to be expected as I have no blood in my body. When I increased it to 100m for 3 seconds it felt the same as that hit by the ruby but still no blue arm.

I guess only pain can be sensed but not because of blood.

At 200m for 3 seconds, it felt 4 times as hard as that hit. At 250m, it felt 8 times as hard. I didn't wanna try to increase it more fearing my had getting cut off.

Wait, how do I know the length of the shirt? And how do I accurately measure the pain as if I were a measuring scale? I used that information so naturally. I guess that's another perk of being a spirit. 

I saw the width of the shirt and I naturally knew it was about 50cm long. Nice.

Since I had no references to how physics worked here, I had to create units to make the process easier.

Let's assume that the force I'm generating when I'm hitting the ruby as hard as I can to my body is 1 Kilo Hay-new unit-, 1 KH for abbreviation. 

I passed the night making equations using three variables: the lateral surface of the object-SL-, the surface of the shirt used -n-, and a coefficient of tissue -Ct- that I didn't use as there was only one tissue. 

After 3 hours of writing down potential equations and trying them out, I finally found an equation that worked for the scale I was hoping to use it for. Sure it's not perfect but it's a start. 

The equation was: (SL/100π)^^((n-50)/50). 

It worked, I could accurately predict how much pain I would feel during 3 seconds using any given surface of the shirt I used. This is basically my way of saying the force exerted by the shirt on a surface for 3 seconds.

I didn't have enough time to make an equation using time as a variable too, and honestly, I don't need to as I can make an unlimited surface of this shirt by stretching it. So using 3 seconds as the set time for this equation was good enough for me.

I tried then to see if it would work on my thighs and my waist. It worked. Hell yeah! It seemed silly that I would have fun in this infuriating situation, but I needed the small ones as they are what makes a man dream of more.

I went back home, entered through the window, and saw that my parents had fallen asleep hugging each other, they looked like they spent the whole evening crying, I went to my bedroom to try to sleep.
