"How do you know that a "photon" does NOT experience time? "

Because it stays the same.in complete vaccuum away from other fields.in ordinary circumstances it experiences change.if it experiences change it can be said to experience time but it does not remember what it did 15 minutes ago no.we remember what we did 15 minutes ago because we can store a photo of what we did 15 mins ago.but we can only access that photo of 15 mins ago now not before now.trailblazers

Speaking of a photon flying in total vaccuum away from other field interference,this can be said to be a permanent perturbance,just like the whole universe is and always will be.if the universe began on one side of a black hole crunch and is going to endup on another side of another black hole crunch,can we really say that anything is changing in the entire universe? The horrific answer is unfortunately no.there is no net change.it copies the pattern of a singular photon flapping its wings in absolute nothingness.it copies it to a T-perfection

I'm still stuck with one riddle and its a gigantic riddle. Does a collapsing universe press inward upon itself,or does it press upon something else.this is a very important question.please note my attempt to cut certain curves out of relativity/abstract and bring the nihilism of the senses back into fashion.let us see if we can actually trust the observer to a further extent than he was always trusted

"
Perturbance/disturbance sounds just like negative/
positive...."

Or negative-negative,or positive-positive.it means "to alter"

   I came across this, Abrikosov vortex in a superconductor.
It's amazing what's out there.
   One for joel, my cousin did a 15 million dollar deal but
died just about the same time that the deal was finalised.
I knew he'd had a brush with cancer but he seemed to be
getting better but it had moved to his brain and that was
that.
