hello everyone, to start off, I'm in no way a physics expert but I think I understand time dialation. for all of this, use the sun as a reference frame. I was reading a thread on here and I thought of something. I'm pretty proud of myself for thinking of this but I would like someone with more experience to verify it for me. The night side of the Earth is moving more quickly than the day side of the earth. The Earth rotates at a speed of about .47 km/s and the Earth revolves at a speed of about 29.8 km/s. This means that the night half of the Earth (for this, let's just ignore the 23.3 degree tilt of the Earth's axis and assume that it's verticle, relative the Earth's orbit) is moving at an average rate of 29.8 + .47 km/s (the .47 is an average rate, it actually only .47 at the furthest point from the sun). The day side, on the other hand, is moving at a rate of 29.8 - .47 km/s (again, average). Does this mean that, since the day side is moving slower than the night side, that clocks, according to time dialation, move slower during night than during the day? I've done some rough calculations with this and if all I've said is true, here's a fun bit of trivia: you age 1.0000000003116756 times slower and weigh 1.0000000003116756 times less during the night than you do during the day. haha. Thank you for your time and replies
edit: I just realized that the fact that the day and night halves of the Earth move at an equal rate relative to each other, my idea might be incorrect. I don't know if this would disprove the idea though, since the night side IS moving more quickly than the day side relative to the sun.
