Me and physics

Guruji ( Art of living) says we are all hollow and empty. I kept thinking how can it be ? if skin is so thin and porous how does the blood not ooze out ? How can the skin stretch and compress so much ?. I was thinking it was some molecular mechanics which I dont know about ( may be there is a biological explanation as well) . May be Guruji was hinting at mentally being hollow and empty giving the example of our body. But the interest in physics made me think about an explanation for this. I also read somewhere that if you could ( imagine) the electron to be the size of a tennis ball the orbit will be several football fields around, the proton neutron will be the size of a marble although heavier by 2000 times.

Also if we could compress all the elements together in the human body, it can fit into a matchbox.

So there is plenty of space between the proton/neutron  mass in the centre to the electron. How is it that we are able to be opaque and not permeable ? some elements made up of these empty units are harder/ softer/ liquid or gaseous in this kind of a porous situation ?.

Recently I got a probable reason when I was listening to Feynman explaining how magnetism works.  The electro-magnetic field in every charged particle makes it a shield for the empty spaces where penetration becomes difficult. It opened a new line of thinking, So skin being porous can also hold liquid inside and bones can be denser than liquids depending on the configuration, because it all boils down to the field of blood/liquid atoms interacting with the field of atoms of the skin. I think this is a generalisation but molecules are made up of atoms and eventually it will end up like that. So every material we can think of are arranged as they are by this energy play ? Conversely does it mean, everything is energy playing tricks by arranging mass( I mean the basic particles and not matter in general terminology) around itself ?

So there is an emptiness within me( or this body which consists of atoms and which are empty mostly) which is permeated by energy fields. Is it not just like the universe where vast emptiness is permeated by energy. ?

So coming back to the normal world that means when I am petting my dog, I am actually interacting with the electromagnetic shield of my pet ( or the skin) with the electromagnetic field of my skin. But I can still feel the texture of the things I touch by interacting with the electromagnetic field ? Is there no physical thing involved except interplay of energy between different beings ? Isnot this energy the same within all living and dead matters.?

Whew just thinking…  I am not sure whether my thinking is right. Feel free to comment.
