The discussion centers on the effects of relative motion on time perception, specifically when considering the Earth, solar system, and galaxy moving at 1,000,000 miles per hour. It establishes that if an observer travels south at the same speed, they would appear stationary in the solar system's frame of reference, while in other frames, they would be in motion. The conversation emphasizes the symmetry of time dilation, where each observer perceives the other's clock as ticking slower. This highlights the fundamental principles of relativity and frames of reference in physics.

Yes, there is a frame of reference such that if the solar system were moving at N mph in one direction and you were moving at N mph in the opposite direction IN THE SOLAR SYSTEM'S FRAME OF REFERENCE you would be stationary in the first FOR. So what? That's how motion works.zuz said:Lets just say for the sake of argument that the earth, sun, solar system, galaxy were all moving due north at 1,000,000 miles an hour. If you were to travel due south at 1,000,000 mph you would basically be not moving at all. How would this affect time for you or anyone observing you?

You're just picking an arbitrary frame of reference here, but ok.zuz said:Lets just say for the sake of argument that the earth, sun, solar system, galaxy were all moving due north at 1,000,000 miles an hour.
No, you'd be stationary in the frame of reference you chose arbitrarily earlier. In all other frames you're moving.zuz said:If you were to travel due south at 1,000,000 mph you would basically be not moving at all.
Just the same as always. Your clocks look normal to you and everyone else's (well, those in motion relative to you) tick slow. Everyone else says their clocks look normal and yours tick slow. It's symmetric. No, that's not a contradiction.zuz said:How would this affect time for you or anyone observing you?
