can photons live forever?

[AntonioLao]

Plenty of photons have been traveling at light speed since the pseudo-catastrophic BB event. They will continue to do so unless they interact with any colliding matter along the way on their aimless (?) but perhaps claustrophobically initiated journey across the universe in order to get away from the each other’s sight. But how does a photon ‘see’ the other photons? If no matter existed, what separated them is just the emptiness void of the true vacuum.

By their very bosonic birthright, nature decrees all photons to be exempted from Pauli exclusion principle. They can in theory take advantage of the superposition principle and a quadrillion or infinity of photons can fit into the eye of the needle with only concentrated infinite energy density to boot.

But why do photons run away from each other? Is it because they are tired of each other’s company? Can living together infinitely be such a boring enterprise? Surely they are allowed to live forever as attested by their longevity. But, I think, the truth is out that all photons really want to die by seeking out the end of eternity and put an end to their tiresome sojourn in an expansive universe into another collapsing one. Thus completing the cycle from where they came and be reborn again.

Maybe photons reppel each other because they are there own anti-particle? (although they have no charge...).

Or maybe they repel because in the other universe parallel to this one, the one that is contracting, the photons of their sort of make them get apart to the ones here and the ones here make the other get near. Maybe this could explain why we accelerate and grow, instead of DE?

Maybe photons reppel each other

for LASER, it's just the opposite: photons attract each other.

Antonio;
The photon is a quantity (Quantum) of energy absorbed or emitted by matter. It is not a traveling particle of light unless you are considering it as a piece of the wave. The waves from a laser are coherently aligned waves. This means that diffraction is minimized due to the alignment of the electric and magnetic vectors. (polarized light) The waves do not repel or attract. They do however have interference.
Particle physicists like to think in terms of particles for everything. It makes the math work better.

but the wave-particle duality of nature is considered as an inseparable existence like the two sides of a coin.

I think this is wrong, because they contradict, light has to be either one or the other.

Dave, it is the wave that is there jsut to make everytihng work better, not the particle.

There are many poor interpretations of the mathematical models of physics, the duality model is just one of them. I am not a positivist, I cannot accept these bizarre interpretations as real facts. In reality there is no duality. We need a better understanding of the relationship of the mathematical terms to the physical reality of nature. Maybe then the positivist and the realist can agree. I accept the math, not all the interpretations.
Let's not make physics another religion that faith is one of the requirements along with trust in the keepers of the temples!

[Guille]

Laboratories would be the temples of science.

What do you mean by bizzare interpretations? Aren't all bizzare? Or all un-bizzare?

[AntonioLao]

do you mean logical positivism?

I asked him (dave) and he explained me this:

positvist: someone who wants the math to work correctly
realist: someone who wants to know why the math is like that
