    I have a question regarding the laws of attraction in relation to our own galaxy. The mass of the supermassive black hole in the middle of our own galaxy is 8.2 x 10^36 kg (4.1 million solar masses). Is it possible that the billions of stars that encircle this supermassive gravitational pull play a part in emitting a repulsive force against it? If so how much of a point percentage would our solar system play (speaking only in gravitational terms)?

    Lol lot of questions but befuddled where to find answers. Anyone have a reference for source material for me to study on the subject? I wish only to investigate the gravitational theories behind this phenomenon.

    No. The billions of stars would add to the galaxy's attraction.

    In what ways are the singularity of a black hole, and the singularity that was followed by the Big Bang connected?

    The one at the beginning of the Big Bang is thought to be massless. Is this somehow related to why masses of galaxies are predicted to be disappearing into a black hole and causing an information paradox?:

    "The black hole information paradox results from the combination of quantum mechanics and general relativity. It suggests that physical information could "disappear" in a black hole, allowing many physical states to evolve into precisely the same state. This is a contentious subject since it violates a commonly assumed tenet of science—that in principle complete information about a physical system at one point in time should determine its state at any other time" (1).

    Could a Big Bang be the exit point of what enters into a black hole? Absorbing the mass at the event horizon, being singular and dense at the passage, and then vomiting the energy into the realm of dark matter again.

    If the black holes are as spherical as this NASA illustration, and "any star collapsing beyond a certain point would form a black hole"(2), then, can we say that the smaller stars also have black holes inside of them but they are not big enough to be passages into new universes or pull their orbiting planets into themselves?

    While the black holes at the centre of the galaxies have enough gravitational power to absorb all the matter, stars such as our sun has enough gravitational pull for our solar system but also are small enough the be covered by the energy they release and thus appearing as balls of fire.

    If we go by the scale, can we speculate that the inner cores of planets like earth has a very small black hole in the centre that "may have a temperature similar to the Sun's surface"(3) and its smaller gravitational power allows it to keep the matter on it?

    All three examples might imply a transformative power relevant to their size; the black hole in the middle of a galaxy transforming entire galaxy into a new universe; a black hole inside a star creates "almost all elements heavier than hydrogen and helium"(4); and a black hole inside a planet is the source of the planetary dynamics and responsible for the production of minerals?

    The questions I raised might sound nonsense. This is because they are all hypothetical assumptions and not based on any physics knowledge.

    Please explain in simple way if you feel like answering or commenting. I am not a physicist, not even a scientist.
