Where did I ever write that I /wanted/ that. I've "solved" the TP a handful of different ways to make clear what is happening. It's not a paradox to anyone but you. If it's not acceleration in the Triplet case, then it's not acceleration in any other case. If it's not difference in acceleration in the equal acceleration case then it's not due to acceleration difference in any case. If it's not due to stresses on the clocks in the slingshot case then it's not due to stress on the clocks in any case. The point is to eliminate every possible cause of the difference in ages in order to find the essential cause.On Saturday, September 13, 2025 at 9:20:03 PM UTC-6 Brent Meeker wrote: On 9/13/2025 12:42 PM, Alan Grayson wrote:* * *Your problem with the turnaround scenario is that you have apparently forgotten high school physics, where velocity is a vector having magnitude and direction, and **acceleration, which you want to avoid, is DEFINED as a change in velocity.
