In summary, the two phenomena you observed, the parallax effect and glare/blooming, are caused by the angle of the Sun's rays and the reaction of the eye or camera lens to bright light.

The other day, I was sitting outdoors and started playing with my shadow out of boredom. That's when I noticed that when I moved my head near my knee, their respective shadows connected even though my head and knee weren't touching. I'm guessing it has to do with the angle between me and the sun and that the sun's light is more like a thick beam than something emanating radially from a point-like source. I'd just like a proper explanation for this phenomena.

Also, why do lights appear to flatten out (make lines the same color as the lights across your entire vision) when one squints or when a movie camera captures a scene with bright lights?

The first phenomenon you observed is called a parallax effect. The angle of the Sun's rays create a perspective effect that makes objects appear to be connected when they are not. When you move your head nearer to your knee, the angle of the Sun's rays changes, and thus the shadows appear to be connected. The second phenomenon you observed is called glare or blooming. This occurs when bright light enters the eye and causes the pupils to constrict, resulting in a flattening of the lights across the entire vision. The same effect occurs when a movie camera captures a scene with bright lights, as the lens of the camera has a similar reaction to the light.

The phenomenon you experienced with your shadow connecting at certain angles is known as the "umbra" effect. This occurs because shadows are not just a simple absence of light, but rather a result of the interaction between light and objects. When the light source is at a certain angle, the shadow of one object can overlap with the shadow of another, creating the appearance of a connection.

As for the flattening of lights when squinting or captured on camera, this is due to a process called diffraction. When light passes through a small opening, like the space between your eyelids when squinting, it diffracts or spreads out, creating a blur effect. Similarly, when a camera captures a bright light, the lens acts as a small opening, causing the light to spread out and appear as a line rather than a point.

Overall, these phenomena are a result of the complex behavior of light and its interaction with our surroundings. It is always fascinating to explore and discover the mysteries of light and shadows.
 

1. What are blobs in shadows?

Blobs in shadows refer to dark, shapeless or indistinct figures that can often be seen in low-light or shadowy environments. They can appear in various forms and sizes, and their exact nature and origin are still a mystery.

2. How are blobs in shadows formed?

The exact formation process of blobs in shadows is not fully understood. Some theories suggest that they could be caused by optical illusions, natural phenomena such as dust particles or insects, or even supernatural entities.

3. Are blobs in shadows dangerous?

There is no evidence to suggest that blobs in shadows pose any physical or psychological danger. However, some people may find them unsettling or believe they have a paranormal significance.

4. Can blobs in shadows be captured on camera?

Yes, blobs in shadows can often be captured on camera in photographs or videos. However, the quality and clarity of the image may vary, and it is challenging to determine the exact nature of the blob in the image.

5. What research is being done to understand blobs in shadows?

Scientists and researchers are continuously studying blobs in shadows to better understand their nature and potential causes. This includes conducting experiments, analyzing data, and exploring various theories to unravel the mystery behind these elusive figures.
