Are some shadows darker and colder than others?

What is the evidence for the existence of a white hole?

Other than theoretical ones, are there any observational proofs?

That shadow on degobah was like really cold just ask luke skywalker so yes some shadows are colder than others

Whoa, I think this thread was edited and changed...
Anyways, there is zero evidence of the existence of white holes.

Of course, there's zero direct evidence for black holes as well. At most astronomers know that there are gravitational systems whose center must have an enormous mass (enough, according to GR to be a black hole) and that the center has no detectable emissions.

I guess that depends on what you consider direct evidence to be.

Well all we have now is a null result, it's NOT a big star at the center of a galaxy. But hallmarks of black holes specifically, things like Hawking radiation and such, have never been detected.
