What is combined single directional speed of earth rotation, Earth orbit, solar system transit, galactic spin and transit, and universal expansion?
Yes, we’re all over the place. Speed is relative. The sun orbits the galactic center at about 514,000 mph (143 mi/s) within its trajectory around the galactic center, but as we orbit the sun sometimes the Earth speeds up or slows down relative to the galactic center. Round and round we go. It’s kind of like this amusement park ride!
