So now, you have the answer and the formula, so may be you could now visualise that if assuming there are 900 trillion, trillion, trillion, trillion, trillion, trillion , 700 billion, billion, billion, billion, billion, billion, billion, billion billion billion billion atoms in the universe and each atom has an invisible link with every other atom, (call it force of attraction as in force of gravity) so how many lines of attraction would this number of atoms generate and you could almost visualise how these lines of force of gravity, (which is invisible) occupies the entire space, what we call empty is indeed not empty!
So now it is within your grasp to visualise that space is filled with this force of lines, so dense that it would diffuse as it criss crosses other lines of attraction, and form a dense but invisible force in empty space, so after all this space is not empty, every nook and cranny is filled with these lines of force.
Please don't try to work this out as you will run out of space! this was just to help you visualise how a number as small as 32 can generate 496 lines and so you can imagine how those atoms in the universe are linked to each other and forming a mesh of dense lines of force, though I know the force depends on the distance between atoms, but nevertheless there is a connection between every atom against all others. like the motorway links all towns with one another.
