AI Thread Summary
The circular rainbow patterns observed when using 3D glasses with LCD screens are likely caused by the interaction of polarized light. When tilting the screen, different colors may exhibit varying polarizations, leading to the circular effect. The phenomenon could be influenced by the type of polarizer used in the glasses and the screen itself, as some devices have different polarizations for each color. Regular polarizers can create distinct visual effects on LCD screens, depending on their orientation. Ultimately, the combination of these factors results in the colorful circular patterns seen through the glasses.

Hi, I was looking through a pair of 3D glasses last night at my mobile phone screen and saw something really cool. If the screen is lit and you tilt it, at various angles you see a circular rainbow effect. The different colours all form perfect circles around each other. I have been trying to find out what causes this circular rainbow pattern but to no avail. Please could someone explain what's going on? I would guess it would have something to do with the polarised light through the glasses and causing some type of interference with the pixels - but not sure though.

Many thanks!

I don't know exactly why, maybe a circular polarizer on the phone screen or the glasses? I don't have 3D glasses but I played with a regular polarizer out of a calculator display in front of many displays and I get different effects ranging from simply color tint changes on many phone screens and certain TVs (my Xperia M and a Galaxy Mini, AMOLED ones like the Galaxy S5 don't have polarizers so a polarizer won't do anything) to the polarizer blocking all light from the screen in a specific rotation in my desktop and laptop monitor (Both Samsung ones) :)

In general, different colors on your LCD screen may have different polarizations (for example, my iPhone has the green polarized in one way and red in another - as a result I see a green or red tinted screen depending on orientation when I look at it with polarizing sunglasses). If I am not mistaken, they are typically linear unlike the 3D glasses that would generally allow circular polarized light through (think about why!). What you are seeing is most probably a result of this.

Thread 'Is there a white hole inside every black hole?'
This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
