You = will see that it is almost the same if not the same as the = characteristic impedance of a coaxial or any transmission line. =20 To say that this measurement characteristic is a proof that a physical = structure exists in free space (vacuum) is not a valid conjecture, any = more than it would be to make the same claim simply because a magnetic = field can be shown to exist in a vacuum.=20 "characteristic impedance of free space The characteristic impedance of free space, also called the Zo of free = space, is an expression of the relationship between the electric-field = and magnetic-field intensities in an electromagnetic field (EM field) = propagating through a vacuum. The Zo of free space, like characteristic = impedance in general, is expressed in ohms, and is theoretically = independent of wavelength. It is considered a physical constant. " I continue:=20 If anything this impedance supports my original supposition that the = aether is a conduit or transmission line caused by the physical = structure of the fourth dimension.of space.=20 The structure that Allen is seeking does not exist in our three = dimensions at all.. Electromagnetic phenomena is a resultant of the = fourth dimension, which some fairly postulate as being experienced by us = mortals as subjective time as we mentally traverse it . Time as we = subjectively experience it is not constant, not from minute to minute = nor from person to person. Spend 60 seconds looking at the second hand = of a watch.=20 Just think of it. You could say that every instant, no matter how = infinitely short in period, is forever.=20 Philip. -- No attachments (even text) are allowed -- -- Type: image/gif -- File: spacer.gif
