Why a Photon Moves at Lightspeed Directly After Being Emitted

As it gets emitted the photon is copied to the next Planck length in a Planck time right from the start. Then the old photon gets deleted (at the start of the second Planck time). i.e. the photon spends a Planck time at every index of Planck length.

Just two thoughts:
  1. Since a photon is the quanta and force carrier of light, how does it not have any choice but to move at light speed?
  2. Your statement seems to imply that a Planck length is the smallest resolvable pixel of space possible thereby defining the uppermost speed of light, yet, doesn't that violate Special Relativity?
 
That has nothing to do with how fast a photon moves.
Sure it does.

Entanglement takes time.

They actually measured it.

So during this time, is the photon "moving"?
 
No Special Relativity can accommodate discrete spacetime.

But doesn't the idea that space is divided into discreet, minimal Planck units of length where nothing can be smaller conflict with both relativity and quantum mechanics? If Planck-sized units exist in one inertial time frame, wouldn't length contraction via the former make those units anisotropic in the other frames thus conflicting with Lorentz symmetry?
 
there is no white light, its amplitude of the wave that makes yellow or blue light seem white. how do photons do this neat trick talanum1 ?
 
toobfreak I bet you're a Rayleigh scattering guy, my last post brings up a clever point, if the sky were blue from rayleigh scattering, the reflection of sunlight would appear blue. but its yellow?

I bet the atmosphere causes the 'cooling' of the sun from blue to red at sunset on earth, whereas on Mars the blue sunset is 'hotter' because of no atmosphere.

Yes, by definition of "movement". At the borders of the time the photon is copied and the old one erased - which is how we implement "movement" on a computer screen.

I predict that in another reference frame Planck length would be longer. You can't say space is anisotropic if in another reference frame it has longer units.

It doesn't "cool" it is just that its light passes through more of the atmosphere at sunup and sunset.

The definition of movement is time. The shortest interval of time involves movement and the shortest possible movement takes time. No time, no movement, no movement, no time. The minute a photon ceases to move it ceases to exist.

Not sure what you are implying but by copying if you mean absorption and re-emission, then there is a change of state and an exchange of energy, therefore a loss.

which is how we implement "movement" on a computer screen.
Can't even guess what that means.

Well yes I can. You only say you can't based on an unfounded prediction. Anyone can theoretically speculate anything, reality does not follow theory.

you know that the reason for the apparent diameter of the sun and moon on the horizon is still unexplained don't you? so unless you want to explain what you just said, or can you? you would have to build it without patch work logical cause and effect from ground up, you aren't going to find that, not yet.

Alberta Gilinsky explained the moon illusion before she passed. Her explanation satisfies the evidence.

Do you guys understand how compactification works in Kaluza-Klein?

Can you explain it to this biologist?
 
if you mean absorption and re-emission
Spacetime don't need to absorb and emit: I postulate that spacetime can copy a particle onto a new position in space and erase the old copy instantaneously.
Can't even guess what that means.
Come on: think of a spot on the screen that is set into motion.
Well yes I can.
Come on: the definition of isotropy is: "looking the same across spacetime" not across reference frames!

Look: the sun and moon shines through more atmosphere at sunset and sunup, then more yellow light gets absorbed leaving more red light in the image.
 
No. I can't explain it.
This is as close as I could find so far:

the metric tensor components splitting into a 4D metric (gravity), a vector field (electromagnetism), and a scalar field (the radion/dilaton), which dictates the size of the compact dimension.

So, something to do with symmetries.

Is this because white light is all the colors of the rainbow that it can be scattered to show prominent colors?
