> a particle in deep space experiences faster relative time, compared to one on Earth, because it has 'fewer transactions slowing it down'. Transactions with what? Other matter? A precise weather and waterproof clock on the ground (so in air) on the surface at the north pole will tick more slowly than an identical clock immersed in seawater several metres below the sea level at the equator, thanks to the oblation of the Earth (and the rotation that causes the oblation). The equatorial water is much denser and warmer than the arctic air, so surely there are more interactions between the water and the clock?
