We are using a sun based time at the moment in the world. We have been calculating our time with the sunrise and sunset. If the sun would stay over us staidly, biological time would go ahead and the sun based time, that people use it in order to calculate their times in a planned way, would be stopped.
Well, how could we stop this time?
By stopping the turning of the world, we can realise this transaction. We could leave one hemisphere in night and the other part in daylight. This does not look possible actually. How can we stop the world, right? This is ridiculous. In today's conditions, guess there is a way to do this transaction:
Our earth turns from the west to east. Earth speed in equator is 1670 km/h and it turns from west to east.If we can fly a plane from east to west, as opposite to normal way, in the equator orbit, a person, who look to the earth from outside, would see that plane would stay staidly but earth surface moves. Because of the sun is out the earth, our plane would get the sun light always. Thus we could stopped the time this way.
