I have a very little knowledge in physics and I am new to this forum. I have read that quantum physics is a branch of physics that deals with microscopic objects i.e. objects of extremely small size (less than 1 nanometer). I have learnt that blackholes are extremely small objects with close to point size and infinite density formed by uncontrolled gravitational contraction of a star. Thus by definition, blackholes being extremely small objects (point like singularity) formed by uncontrolled gravity should be microscopic and therefore should obey quantum uncertainity just like any other microscopic object would do. Is it a correct conclusion or is there any misconception somewhere in my understanding? Is quantum mechanics applicable to blackholes? This doubt occured to me a few days back. Please clarify me as early as possible. Advanced thanks for your kind response.
