I can’t wrap my head around gravity.
Or any kind of force.
In: Planetary Science
Mass *doesn’t* attract mass. You’re mistakenly comparing gravity to magnetism, but gravity is not an attractive force between 2 things like magnetism.
Gravity is the “bending” of spactime caused by mass (or more accurately, the stress-energy-momentum tensor). Anything moving through space simply follows that curved spacetime, including massless things like light. The mechanics of this are well understood in general relativity.
As to “why,” that’s a philosophical question and not a scientific one. Science answers how, not why. We already know how through general relativity. Why simply isn’t the kind of question science answers.
