From quantum perspective we can be explained as stick of metal which just got hit the space of solid state of quantum states of sub particle matter, condensated ice and stick begined a tsunamy from end to the middle. Those are the gravity waves, but you need to shift it 4 diemensions higher. Time's perspective of somebody's outside of our waving on the ocean would probably won't be very stretched out like minimum or maximum of a function, but it's going to be wavy with standard deviation, but stable median. It can be faster elsewhere in the universe, depending on how many stack of 3D spaces are being contracted from outwards to center pushing a matter in front of them, but this buble consist of something that interact with matter as it goes inside. If we stop matter to bouble interaction, we would be free of gravity, but remain somehow still located in space with current velocity. This, by the Einstine, anti-time wave which indicates clock in the universe and is increased in high matter density, due to multiple wave targets, maybe the point is not in particle, but some gel that is containing it, to open pores and let gravity wave pass trough. This time wave and gravity wave that gets denser together creating infinite time dilatation doesn't have to hold. Therefore they are two simultaneous waves which correlates like current to moving magnet. Just that they share a common building block, this can be decoupled like magnetic shielding, if we could get quantum state of space of this particles being decoupled, we could travel time and space independently, however to find out that we need to explore this coupling and how universe forms energy couples. Possibly space filled by void around you would be enough to travel time.
