Just take gravity and throw it into the trash can, two object do not attract each other. What there is is up and down and different density. A rock is more dense then air so it falls down, simple. Helium is less dense then air so it goes up. Easy solutions tend to be the right one.
Next time there is a full moon your could always test that moon light is cold for yourself. The moon is so bright these days so it gives off so much cold light. Find some moon shade then you can see that the temperature goes up.
