If I point a laser at a strand of hair, what pattern would it theoretically make on the wall?
What do our modern mathematics predict?

I'mma say that lazor pulls some neo-level shit and bends around that hair like its nothing.

Yo will see an interference pattern. What you're doing is the same as the double slit experiment.

But how would it look like?
It is the opposite of a single slit, as there are no slits.
What would our models predict?

2 Slits. The strand of hair forms the bar between the two slits. Imagine the laser like a really bright light held far away from a pinhole. It forms the bars to either side of the pair of slits.

But why? How does that satisfy either wave or particle?
This is a wave simulation I found online.
Double slit on the left and an obstacle on the right.
No matter how small the obstacle is, we don't get a similar pattern to that on the double slit experiment.

Here is a better one.
The pattern we get is different.

Your simulation is showing waves coming off the source in all directions like ripples in a pond. To simulate a laser make a thick wall with a narrow passage through it. Make this absorb the waves instead of reflecting them if that's possible. What comes through this will be a narrow beam of waves traveling in an almost uniform direction. In front of that put an obstacle to simulate the hair. The results should be the double slit interference pattern.

Not this one >>12548845
In this one, the source is the entire top side.

Since the source is the entire top side, you can assume it is the narrow laser and that the circle is the hair. right?

If I misunderstood what you meant, here is the link:

The laser would slice through the hair because of its laser power and then blast a hole into the wall. Next question

That's still not an accurate depiction of a laser though. IRL when you run this experiment the interference pattern will be wider than the laser beam. You're not seeing that because the beam is set to be the entire width of the simulated area.

I tried to get as close to making a laser as possible.
Added a circle to be the hair.

Looks nothing like a double slit.

This is what a double slit looks like in the simulation.

Depends on whether you look at the hair or not :^)
