What is the biggest obstacle to proving that black holes really do exist?
Probably the fact that they can't be seen, in any wavelength, and that their properties can be inferredonly by observation of their effects on their surroundings.
Is there a concept in mathematics that is impossible to prove a thing does not exist?
There is no such concept because it is not true. There are many mathematical proofs based on proving the non-existence of a thing. The following example should demonstrate. I want to prove that the biggest number does not exist. Let us suppose it does exist, and let us call it B (for biggest). But then consider B + 1. B + 1 is bigger than B (this can be proved as well). So B cannot be the biggest number. That is, there is no such number B. In other words, the biggest number does not exist.
Is a ghost real?
There is no scientific evidence proving that ghosts exist.
Obstacle to provide that black holes really exist?
The biggest obstacle for proof of existence of black holes has always been our inability to observe them directly, due to their nature of absorbing light and never emitting it (since the escape velocity of a black hole exceeds the speed of light). However, there is abundant evidence of their existence. For example, studies of the orbits of stars near the supermassive black hole at the Milky Way's core have shown that no object other than a black hole could explain their path - otherwise, the stars in orbit would hit the object (i.e., it is so small and so massive, that there is no other possible explanation).
What is the biggest black dwarf star?
It is not believed that any black dwarfs exist yet, as the universe is not old enough for a white dwarf to have cooled into one.

Do Black black widows exist?
Yes, black widow spiders exist and they tend to be black in color (hence their name).
Is there a concrete evidence that dinosaurs doesnt exist?
There is no evidence against the former existence of dinosaurs. On the contrary, there are numerous fossilized bones from over a thousand dinosaur species proving that they did exist.
Do Mermaids have weaknesses?
Their biggest weakness is that they don't exist.
Can you get black lions?
