What is the evidence for the existence of a white hole?
Other than theoretical ones, are there any observational proofs?

Anyways, there is zero evidence of the existence of white holes.
Drakkith said:I guess that depends on what you consider direct evidence to be.
Yes, some shadows can appear darker than others. This is due to the amount of light that is being blocked by the object creating the shadow. The more light that is blocked, the darker the shadow will appear.
Yes, shadows can vary in color depending on the color of the object creating the shadow and the color of the light source. For example, a red object may create a slightly red tinted shadow, and a blue light source may create a bluish tinted shadow.
Yes, shadows can have different temperatures. This is because shadows are caused by the absence of light, and different surfaces can absorb and release heat at different rates, resulting in variations in temperature within the shadow.
Some shadows may appear colder than others because of the color of the object creating the shadow. Darker colors tend to absorb more heat, making the shadow feel colder. In addition, the angle and intensity of the light source can also affect the perceived temperature of a shadow.
Yes, shadows can be measured using a variety of methods, such as using a photometer or a shadow length ratio calculator. These measurements can help determine the angle and intensity of the light source, as well as the size and shape of the object creating the shadow.
