Which is heavier 1 kg cotton or 1 kg iron?

Welcome back guys,
The above question must have been asked to you at least once in your life by your elderly teachers or friends.If not I am asking you today.Actually the answer lies in the fact that whether you are weighing them in presence of air or in vacuum.If measured in air the weight of cotton would be felt less due to the upthrust of air on it,giving  it bit of floating effect.But in vacuum both will weigh the same.
Thanks...

Due to the fabric nature of space-time this can be assumed that we can enter from past to future and vice versa through these holes known as worm holes created due to rupture in space time fabric due to movement of celestial bodies including planets. Time is a man made straight dimension but in our universe time is not moving forward rather everything is happening at the moment. It is like a 3hrs Bollywood movie being watched in a DVD where the time period for movie or event is fixed and we can go backwards and forward. Similarly events occuring in universe are fixed and we can rewind or move ahead using worm holes.  This concept is hypothetical based on journals ...
