text: are we in space? ok so for the last couple of months i have been having this debate with my hubby about where you actually are we you are in the air on an aeroplane. my dear hubby seems to have it in his head that as soon as you leave earth (as in leave the ground) you are in space! my point was that when you are on an aeroplane although you are leaving the ground of earth you are still in planet earth just not on the ground otherwise you would be in space and we all know there is no gravity in space!! im trying to explain to him his point is wrong but i cant do that without facts!! please help me try and tell him he is wrong because he is driving me mad!! hope this makes sense!! looks like you have a couple of people with physics degrees to give you the correct answer - and prove that you are right.  my question though is - how does your husband get away with thinking he's right about anything?!  i'd put him through the ringer for this one!
