On page 129, of the book by Mr.Vedral, "Decoding Reality", it points out that electrons behave quantum mechanically, their spin measurements could be correlated in the vertical as well as the horizontal. I think this means that the electron being a four dimensional object allows the other three x,y & z dimensions to spin around their axis in common, that of time x light velocity. Time may even spin around one or more of the other three axis, in either the clock wise or anti clock wise directions of rotation, just as the other axis x,y & z can smiley - winkeye ?

Is a photon emitted near to a massive object, like a ball squashed mostly along the z & time axis. Which as it moves away from the object becomes more rounded. Causing its rate of four-axis vibration to become more red shifted, due mostly to the z axis expanding & time axis dilation reducing smiley - erm ? Can time vibrate along the time axis?

Could a photon be a four-axis object that is continually turning from right side in, to inside-out, with reference to the time axis, a spherical vibration expanding & contracting then inverting expanding the other way before contracting again, about the x,y & z axis? While it is also traveling at light speed in the z direction? Does a photon passing through a gravity field have its x & y components shortened towards the mass causing the field, squashing the ball like photon towards the mass?

Time for the photon on the side nearest to the object`s mass passes slower than time on its far side, and because time at different locations is somehow elastically joined together, the photon slows down while its direction is being angled toward the object smiley - smiley. What are these time effects, flow rate & elasticity? Special Relativity`s, Proper time = proper length divided by proper light speed; hence dtau=((dx^2+dy^2+dz^2-ds^2)^0.5)/c, seconds, where ds & dtau are the proper length & time, the length & time that may wiggle about as space-time varies from even to event! Letting 1=dx=dy=dz=ds, then proper time, dtau=((2)^0.5)/c, or 1.4142135/c seconds?

Setting lengths dx,dy,dz & ds=1, gives c/square root of 2 = root mean square of the peak proper light velocity smiley - smiley .

Provided ds=dx=dy=dz, then proper light speed = c(2)^-0.5 =ds/dtau,m/s. and you have an expanding ball of time!

A Photon maybe an oscillating volume of three-space in which time runs at a different rate to the outside space-time`s rate? Since the energy stored within a photon depends on Planck`s constant x its frequency, the higher the frequency, the smaller the photons volume. Where volume is assumed to depend on the photons wave length c/f = dx = dy = dz? smiley - erm

If a high space-time oscillation frequency photon is smaller than a hole, it may go straight through, or bounce of the sides, but if its larger than the hole it may take a while for it to squeeze through? smiley - erm Or if the hole is very small it may never get through, maybe rolling around the object instead?

Sorry just realized a photons wavelength, or light speed divided by its frequency, is a constant value, and its volume maybe related to its wavelength, while the time rate it contains maybe oscillating instead of its volume? smiley - erm

See post104, which suggests that the rate of time maybe different for near & far sides of the photon in relation to another objects gravity field. Time may stop for the photon along its direction of travel, but should continue to oscillate at angles away from its direction of travel.smiley - smiley

The photon is like a squashed ball or shock-wave, with little or no forward length, and close to maximum time dilation. Although it should still enclose a volume of varying time dilation, since otherwise the photon would be unaffected when passing through varying gravitational field strengths.

Since a photon maybe a space-time shock-wave, with forward momentum (p=h/wavelength), does it have a disc like cross section, perpendicular to its forward motion? If it does, would this imply that shorter wavelengths are less likely to be impeded than longer wavelengths?

The trouble with the idea of a photon resembling a shock wave is that it would require an input of energy to maintain it. A better alternative maybe that time passes so slowly, that the photon gets to where its going before it can radiate away its time oscillation energy? smiley - erm But then there would need to be a tired light theory for older photons, like those arriving from the big bang? Of course photons from before the big bang must be really tired?

Had a quick look in I.R.Kenyon`s book "General Relativity", but it (sneakily) avoids speculating as to what goes on within a photon, due to a gravity field smiley - winkeye. See page 16, gravitational spectral shift: the ratio of fractional change in frequency to actual emitted frequency is being compared to the ratio of velocity attained to light speed. For some reason the book uses " v" for both frequency and velocity, although its probably a case of my glasses need a good cleaning!

Why not try out the science podcast web site at; "thenakedscientist.com".smiley - smiley Could the apparent expansion of the universe be due to a fictitious force? If gravity tends to clump galaxies together, into clusters and strings & sheets, then the distance between some galaxies would indeed be expanding while other distances contract? Will our universe end up looking like a tangle of string(or even, odd socks)?

Are photons deflected by an electric or magnetic field? Maybe its the potential energy held within an electric or magnetic field that causes space-time, to deflect the path of the photons? If the electric and or magnetic field were pulsing at the same frequency as the photons, would they be more efficient at deflecting the photons?

Do photons zig-zag while passing through electric and or magnetic fields as their wave polarity alternates? If they do, and by an amount proportional to the field strength, would this contribute to their uncertain position, until they are eventually detected? smiley - erm

Decoding Reality, makes good use of the Hitchhikers Guide`s forty-two, on page186, to come up with an estimate for the number of bits of information spread over this universes surface boundarysmiley - smiley. But as information is exchanged inward and outward, to other destinations, across the boundary and or reflected back from it, its distance and area increase with age, the older the more information exchanged?

Relativity says the spectrum of photon colors are blue shifted going toward a mass/object and red shifted going away, depending on which direction the camera happens to be pointing.smiley - smiley The gravity potential phi=GM/r, j/kg or velocity squared, adds or removes energy from the photons kinetic energy. Thus change in frequency = + or - original frequency( phi x change in height/original height)/c^2 , Hz. Photons are mass-less particles, and yet they have kinetic energy due to their electric & magnetic fields angular momentum, hence mass?smiley - erm This implied mass varies with the photons final position and direction within the gravitational potential. Photons hide their masses within their e-m fields, their hidden masses are at right angles to their direction of motion and at right angles to each other?

The further away from the attracting objects mass, the less energy is added to, or taken away from, our photons. But the gravitational potential is trying to take or add energy to each of the photons four dimensions, not just the z dimension between the photon & the object. Since the gravitational potential expands & contracts all four space time coordinates together. An important thing to notice is that the gravitational potential fades going away from the object, taking ever less energy, hence reddening the photon less & less.smiley - smiley Photons going towards the object gain energy, more & more. If the gravitational potential were strong enough, would the photons emit a cascade of other photons & particles, slowing the original photons decent?
