We all learned at school that to all intents and purposes, considering the vast distance they travel, the sun's rays are parallel. But look at any cloud hiding the sun and the rays spread out in all directions. I gues it must be in relation to the distance we are from the cloud but a more reasoned explanation would answer something which has puzzled me for years!

I read moon mission astronauts aged approx. 2sec. less than the rest of us due to reduced gravity. Also, two synced atomic clocks, one on the surface, one on high altitude aircraft, soon unsynced. If a spacecraft traveled a very low gravity path could the occupants survive hundreds or thousands of years?

i think that there must be some maths involved which can predict correctly, for example the time taken to orgasm is inversely proportional to the amount of oxytocin in ur blood !!! and there must be constant to be multiplied too !!
