Hello, I was just reading how the second law of thermodynamic is the only principle of physics that is irreversible, and that fact appears to have a correlation with how we view time and how time can only move in one direction, being the same as the flow of entropy. So, are entropy and time really synonymous? I was doing a thought experiment to try to settle the issue and envisioned our universe with entropy sped up at twice the rate. Clearly, if entropy was to increase at twice the rate, things would age twice as fast, plants would grow at twice the rate and live for only half as long. For most anything, it would appear, as though time itself had been sped up. But, then I thought about the spin of the Earth. For time to run at twice the speed, then naturally the Earth would have to rotate at twice the speed, but I don't see how an increase in the rate of entropy could have any effect on the speed of the rotation of the Earth, or its period of revolution around the sun. So, now I'm thinking entropy and time are not the same after all. My question is simply: Would a doubling in the rate of the universe's entropy cause the rotation and revolution of the Earth to become twice as fast?
