The Transmission of Gravity
Since the early 1980’s images constructed from data obtained by the technology of electron microscopy have provided a visual confirmation of the ultimate, natural division of matter. But, while this is acceptable empirical proof of the existence of atoms and of their structural arrangements in solid matter, these images show no sign of the motion, or of the separation of atoms in macroscopic matter that is a core assumption of current atomic theory. Instead these images give a clear impression of an ‘apparent continuousness‘ *(1) of atoms, as in the image below, courtesy of IBM Almaden.

The historical origins of this concept of the separation of atoms by a volume of ’empty space’ go back to Greek philosophers of around 2500 years ago, who invented the vacuum in order to be able to explain the fluidity of air and water with their oddly shaped atoms.
This concept was dismissed by Aristotle whose four elements model was accepted until 1644 when Torricelli was generally assumed to have created a perfect vacuum in his experiments with mercury, which contradicted the then generally accepted Aristotelian wisdom that this state was not possible in any circumstance. It can be no coincidence therefore that three years later, in 1647, Gassendi resurrected Democritus’ ‘kinetic’ atomic theory, which was dependent on its ‘existence’.
When Torricelli’s apparatus was later shown by Pascal to be an indicator of atmospheric pressure, this “supported the belief that the atmosphere is only a thin layer surrounding the earth, and that outer space is empty” *(2). This belief of space as essentially a vacuum perpetuated until the mid 1900’s – “Half a century ago, most people visualised our planet as a solitary sphere traveling in a cold, dark vacuum of space around the Sun.” *(3)
Of course Torricelli’s ‘vacuum’ was not a perfect one, but contained mercury vapour ‘boiled’ off in the low pressure created by the weight of the column of liquid mercury, however if one Googles images of barometers, virtually all indicate, without qualification, that the space above the mercury is a vacuum.
