    A recent discovery in gravity is that while gravity is a ‘‘constant’’, it actually fluctuates from place to place,

    I guess you are referring to the c9ncept of dark matter?

    To anyone who does not know what dark matter is:

    Dark Matter is the “solution” for differences in the real gravitational force a star has and how much gravity it should have based on calculations. Dark matter basically is matter that does not interact with light in any form (and therefore can not be detected) but still emits gravity.

      Not “gravity a star has,” but the motion of stars around/near galaxies. It is the general motion of groups of massive objects that hints that there is a lot more mass ‘around’ most (not all) galaxies than what matter we observe could possibly account for.

      The ‘not all’ part is critical, because it points to something actually being there as opposed to the theory of gravity or relativity breaking down at larger scales.
