    All the current physics fields are constructs overlaid on space-time. So there is some pervasive EM field that is magically maintained by localized charges. Gravity according
    to GR is not a field, it is geometry of space-time. (That is why quantum gravity has not been derived yet.) Using Occam's razor, it is more plausible that space is the field that has
    EM as a property and the curvature property advocated by GR. (I have already posted on the non-existence of the time dimension but this has no relevance for the current
    topic). So photons (virtual or real) are quantized waves on the space "medium" or field. The speed of light is a property of space itself and as space evolves (post Big Bang),
    the speed of light changes. Cosmologies that have variable speed of light remove the BS of "hyper inflation" and other deus ex machina hacks.

    The video above is a useful one in that it debunks the myth pimped by the "mainstream" that the Michelson-Morley experiment disproved the ether and "proved" relativity. I think
    the ether was a naive construct and properties such as ether flow are not plausible. It does not have to have the properties of a fluid, it can have the properties of a solid, or
    anything outside of our limited experience. What would be the substance of this medium? It was much like the field fetish of the anti-etherists where some medium was imposed
    on top of space. The phobia of space is long standing and across the spectrum.

    Gravity is a field, we just don't have a quantum model of it, only a classical one

    But if you take a region of space, then for all co-ordinates within it you can draw an arrow and a value representing the direction and the force with which gravity is going to act on you at that location. So near a planet all the arrows will be pointing towards the planet and the closer to the planet, the larger the value.
    That's a field.

    In exactly the same way as you might sprinkle iron filaments across a sheet of paper and then bring up a magnet beneath and watch all the filaments re-arrange themselves according to the strength and direction of the electromagnetic field at any given point on the sheet of paper.

    I forgot to add that fields are circular. What came first, the particle or the field? Field theory really points to particles being part of the field. So
    "virtual" photons are localized quantum entities of the field. Take away the field and there is no photon.

    Modern physics such as the Standard Model is glorified book keeping. But at the same time it has rabid pretensions on fundamental insight.

    It really is absurd that Occam's razor was invoked to choose relativity over the much more sane absolute space-time interpretation of Lorenz and Poincare.
    The fig leaf covering logical contradictions as "paradoxes" is invisible. The moronic ether debate of the late 1800s corrupted science to the present day.
