If someone found a motionless string reaching vertically up into the sky and hanging down nearly to the ground - then should that person consider it as evidence for UFO's ? [56]
Or could there be an explanation in agreement with the well-known laws of Physics?
How long would the string need to be?
I don't have ans, so only solutions with elaborate explanations to be entertained.
