Recently, I have proposed a theory about Black Holes:
Black hole basically stretches any object headed right into the singularity of the Black Hole, making it smaller and smaller (Spaghettification). So once the object reaches at the size, reaching a Quantum Level Size (smaller than an atom), the gravity of the black hole will get flipped and will work in the Reverse Direction; gravity at the quantum level is “repulsive” instead of being attractive. So due to this “repulsive” gravity, this Black Hole will throw out that object, it maybe in the form of Hawking Radiations, or the Black Hole will be in a Superposition State, Black and White Hole simultaneously, and will work as a white hole, and this “superposition” state of the Black Hole would be Wormhole.
That means, a Black Hole is existing as a White Hole simultaneously, it is just that an object has to be infinitely small to escape a Black Hole.
