I'm an amateur, but was wondering if you experts can help me wrap my head around gravity velocity and time; and the universe. If as gravity increases time slows down, isn't time faster on earth than on the sun? And faster, still in interstellar and intergalactic space? Also, if the universe is expanding, does that mean time is slowing down? How is time affected by galaxies moving apart from one another or for that matter from the location from which the big bang started? An please no one line answers like "it's all relative" Thanks.
