I know. That's why I said speed. The way I learned it, velocity includes both magnitude and direction. I didn't want to get into discussion of the rate of directional change of points on a rotating sphere vs points on a rotating disc.

if you can live on pancakes you can live on a flat earth.

-Removed-I was thinking if the disk was rotating around what we think of as the poles, the time of day would be very close everywhere, since the disk would be something like 12,000 km across, at 148 million Km (radius of Earth's orbit), X 2 X PI divide by 12,000 means from the position of the sun, from one side of the disk to the other would be an angle change of about 1.6 arc seconds, so as it spins around, the angle of sunlight hitting the disc would be essentially identical from one side of the disk to the other no matter the orientation of the disk with respect to the sun. So the time would be the same everywhere.

Originally posted by wolfgang59I think you better go back to the drawing board. A sun on one side or 2 suns, one on opposite sides of Earth will still produce the same time zones we have now because at the perifery there would be sunrise and sunsets and in the middle it would be high noon. You can't get around that on a round planet.
duh! The dimmer switches for the suns are synchronised. 😛
