How Does Glycerine Make a Bottle Invisible?

AI Thread Summary

Glycerine can make a bottle appear invisible due to its refractive index being very close to that of glass. When the refractive indices match, light passes through without bending, causing the bottle to blend seamlessly into the glycerine. This phenomenon occurs because refraction only happens at surfaces where there is a difference in refractive indices. As a result, objects submerged in glycerine can become nearly undetectable. Understanding this principle highlights the relationship between light behavior and material properties.

Refractive index. Some liquids have refractive indices very close to those of some glasses, crystals, and other transparent solids, and the solids can appear to disappear when immersed in them. Refraction occurs at surfaces when the indices of refraction differ, but not when they are the same (or at least very close).

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...

Thread 'Is Gravity an entropic property like Surface Tension'

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
