About past, present, and future having the same equally valid status in Relativitry. A. Erlitzer says that there is intuitively something special about Now . Even though Mudlin sets out the argument that past, present and future must exist in order for different contadictory slicing or the passage of time to happen as It does according to SR. He does not however take this further by saying it which way the 'events' persist, presumably imagined as being the material 3D reality that has been supeseeded set out along the time dimension. An existing realm, as real as the present, (that might be visited by a time traveller.) I don't agree with this ,as information released at the time of an event can persist in the environment and be recieved later as sensory input.
So the process of passage of time (recycling and reuse of the material part of the universe ) continues and with it universal becomming.

      The sequential nature of historical events is set out. Later on T. maudlin argues that a person seeing a star explode in the present is actually witnessing somthing that happened long ago. The person is only now being informed of it. He says it is similar for all events, in that we are seeing what is already the past. I agree that the event is not really happening in the present. No mention is made by either guest of the observer producing a partial simulation from sensory data recieved from the environment, released into it at the time the event materially occured.

          Georgina Woodward
          An observer does not recreate the entire event, only that which can be made using the sensury data available at that location, That gives a particular viewpoint in space at a particular time.

            The quantum of vision, visual stimulation, is te photon particle. These are shed into the external enviroment by matter, abd absorbed from it by matter. If the matter is a phiotireceotor cell, containg a photoresponsive pigment, a particular wavelength of input vibrational energy will stimulate a response. Different cells respond to different wavelengths.

              Georgina Woodward
              The shed photon particles affect the surrounding (non matter) substance , causing its vibration.
              They are also affected by it. The location of the particle is affected by the interference pattern of waves combining after separation. BOUNCING OIL DROPLET experimentes provide avisual analogy.

                  This is not a particle wave as described by the wave function of quantum mechanics but an actual particle produced by the matter atom and interacting with the already present (non matter ) filled environment. This allows there to be a viable alternative explanation of the double-slit experiment.

                    A photon particle, quantum of vision, provides the wavelength of visible light that a phoreceptor cell is able to respond to via interaction with the pigment contained by the cell. Or it can activate a photocell belonging to a device such as a ditgital camera or robot. OR cause reaction in a light sesitive film of a film camera. Photons also give relative position information , of the many photons input -after passing through a suitable lens. The relative position of parts of the source object, when the photons were shed is knowable from this. The multiples of photons arriving at a photoreceptor gives total energy or intensity (brightness) information. The various inputs , suitable quantum , position, intensity are used in processing that eventually leads onto subject recognition process and image/semblance formed. Often along with associations, such as name , memories and learning connected with the source object identified. Wavelength is converted to Colour product if its a bright light adaption cone cell that's stimulated, lower intensity input is insufficient to stimulate a cone cells but can stimulate monochrome rod cells.

                    We need a correct understanding of passage of time, including why two dimensions that relate to it are needed, in order to include what we see there, as well as material existence.
                    Also we need to be using the correct number of spatial dimensions that apply to the real material World / Universe, existing -Now. and vision, Treating block time as history of the material world, that isn’t extant laid out along an imagined time line.
                    Correct or better understanding of photons and how light is transmitted together with self similarity of nature at different scales, Using the corrections together with relativity. To have both what occurs unseen and products of vision as parts of physics. Both important but not the same.

                      Physics has been an attempt to describe and understand the reality we live in. It is unlike mathematics in that it should always relate to the World /Universe whereas mathematics need not. Impossibilities that are allowed within mathematical space, can not exist in the real World/Universe. QM mathematics occupies a different realm. Why is it held as an explanation of the realm we inhabit, though requiring we accept non locality, or faster than light communication. Surely enough to reject it as the pseudo-science it is

                          Can QM be correctly described as science. I think it is more correctly described as pseudoscience​? i think investment of scientists time and research funds gone on long enough. Is business investment in this area unrealistic about potential breakthroughs and technologies.
                          I would like to hear from members, and other professional physicists, and interested amateurs with a deep understanding of quantum electrodynamics theory or theory of science. I’d like to hear their defense of QM, as it is.

                            Gravity Two models are needed as the background for each is different.

                            1.Einstein /Minkowski curved space-time fabric corresponds to what we see, by the process of vision. It is a perdurant model in which matter bodies / objects and background are spread over time due to vision being possible because of photon particles being transmitted and the photon particles being delayed by gravity, affecting time of receipt.

                            The other model pertains to actual matter, existing wholly-Now. That can’t be seen. We see 1. This is an endurant model. Objects and background exist wholly at -Now. Their existing is not spread over time. Here we can use Newtonian gravity,which doesn’t take notice of time. matter with gravity affects other matter atracting it and particles if matter in the environment, non matter-bound particles in the environment (plasma) and other space filling substance, through which light is transmitted. In this model rather than having a constant speed of light assuming the vacuum of apace to be everywhere a vacuum,. objects of matter are affected by the density of what they pass through, the more dense the more light slows and bends casing refraction.
                            Space that we think of as empty may not be. It may contain matter, or non matter-bound particles or gravitationally significant other unseen substance. This could be the elusive dark matter ,which is hypothesized to exist but is absent from most models.

                              No need to fret any longer over the meaning of model 1.Space time represented as a continuious background, like a sinlge deformed elastic sheet. Curved in response to the presence of the gravitational mass, the gravitational mass acted upon by the curvature of the sheet. This is what is produced by regarding the sensory information. It is not material reality but a model of a vision generated observation product. Light rays are said to be curved in proximity to the gravitational mass. This means the photon is delayed compared to what it would be undfelected. As space-time is a generated product, caused by delay of receipt of photon carried sensory information ,the non eucidean nature of space-time need not concern us, it is not a model of what exists.

                                1. Newtonian gravity is not an approximation of Einsteins. They have completely different backgounds/environments 1. set in a generated model of space-time. 2.set in space without taking time into considseration, as it has no effect on unchanging masses. For changing masses passage of time is relevant.

                                I should mention that Newton did regard the creation to be three dimensions of space and one dimension of time. For him it was a matter of reiljigious belief. That there is no time without God, ie. nowhere God isn't ,so God's creation must be everywhere in space and time with God
                                I am proposing that what exists is not spread along a time dimension but exists at one 'time'.
                                The history of what has existed can be imagined spread along an (imaginary) time line. Not any part of the geometry of existence/the materiaL World /material Universe.

                                  Re.2.there is stilll a deformation of the environment around a massive body. Due to its presence and mass .Where there is more gravity there is consequently more attraction affcting other bodies of matter, particles of matter other attracted materials and substance.

                                      By environment I'm refering to filled space.which is not space-time. Absolute time is not part of the model.
