(thats true in two sense, they makeup everything as we know, and what it also implies, the myth that empty space does not constitute anything, thats what atom is lying about, its lying about empty space if we are to believe it, but our new knowledge: even empty space weighs)
… And Lawrence Krauss says (– in his amazing talk why there is something rather than nothing) there is large empty space in matter thats also far more heavier than actual matter. eg Proton constitute of 3 quarks whose masses are collectively not sufficient to explain why proton mass is so much higher than that. (– which is important from the view point of the 10 ideas I had shared regarding what LHC can do, the proton mass being much larger than its constituent quarks)
The only explanation is the large empty space which anyway has a large fluctuation energy. So the empty space in our body is more heavy than what we actually eat and our actual flesh etc. 80% of our body weight could be empty space, our actual weight is only a small fraction coming from the atoms of the flesh and fluid we have.
I am Amused (LoL) and no it does not come from the air we breath, thats still matter. So the only difference from why we are heavier is we are more densely packed than air molecules are in our surrounding and the air is flowing freely into adjacent regions. Our flesh does not expand freely into adjacent region or we would even weigh much more.
So its the amount of space we have packed into our body in a small region rather than the amount of flesh-fluid-matter we have really that makes us so much more heavy. (– No Lawrence didn’t have time telling so much so I am just flowing freely with my Ecstasy) So its not really atom which makes up everything but it has packed a great deal of myth into its making. The myth of empty space being zero energy is no more true. Empty Space weighs.
Also thats the reason why matter would need empty space because then the reactions would be softer. At that atomic level Matter hits you and you adjust that like a secretary adjusts your tone as a learned philosopher and there isn’t much damage or breaking of bonds.
Myths make up most of our world and we shall not believe them.
