    Perspective Photon
Click For Summary
SUMMARY

This discussion centers on the concept of a photon's perspective and the implications of traveling at the speed of light. Participants assert that a photon does not possess a reference frame, leading to the conclusion that it cannot have a perspective or cognitive experience. The conversation also touches on the asymmetry present in relative speeds when comparing subluminal and luminal travel, highlighting the unique nature of light's behavior in physics. Pervect emphasizes a policy of redirecting discussions on photon perspectives to previous threads, reinforcing the established understanding of light's properties.

PREREQUISITES
  • Understanding of special relativity and its implications on speed and reference frames.
  • Familiarity with the concept of light speed and its effects on mass and perception.
  • Knowledge of cognitive processes and how they relate to physical movement through space.
  • Basic grasp of symmetry in physics, particularly in relation to relative motion.
NEXT STEPS
  • Research the implications of special relativity on light speed and reference frames.
  • Explore the concept of mass-energy equivalence as it relates to photons.
  • Study the philosophical implications of perspective in physics, particularly regarding non-cognitive entities.
  • Investigate previous discussions on photon behavior and reference frames in scientific literature.
USEFUL FOR

Physicists, students of relativity, philosophers of science, and anyone interested in the nature of light and its implications on reality.

I guess this is my last theme here with this nick and from this IP:) But I just love the answer that came to my mind (maybe it is posted somewhere here, but I could not find it).

1) Our reality:
If the thing traveling would have the brain operating the same way as our brain (or any other physical process know to us) is operating, then during a travel at the speed of light we would see him having the last thought before starting the trip halted all the time in his head. For the thought to move a bit ahead he would have to observe the chased light to move away from him a bit. So no our space could look flat to him or anything until he slowed down a bit. I.e. he would be unable to reflect about anything in our world during his travel. He will be able to tell nothing about our world as he will not be able to have a thought while crossing it.

2) Photon's reality:
At the moment he starts the travel He would see the whole our world shrink to 0 size having 0 mass and running away from him in the opposite direction of him with the speed of light. Or rather him growing as a new universe and us becoming just a photon in that universe.

If relative thinking then relative thinking till the end, so to say:)

Pervect said when locking an earlier thread:

Perhaps I'm a bit irritable today, but I'm formulating a new policy - we'll see how it goes. When I see the words "photon perspective" in a thread, I'm going to make a quick note that a photon doesn't have a perspective, refer people to the previous discussion on the issue, and lock the thread.

and when locking another:

In accordance with my new policy, I'm pointing out that light does not have a reference frame, and locking the thread...

Pervect,

Where is the reference to earlier discussion? I am entirely happy with a photon not having a perspective, a photon not being a cognitive being. But I want to read earlier stuff about a photon not having a reference frame.

It just seems to me that if a photon has no reference frame then there is some inherent asymmetry.

When subluminal approach speeds are considered there is symmetry in that the speed at which I approach you (in your rest frame) is equal to the speed at which you approach me (in my rest frame). This should make our respective overall relative speeds the same, even with a tangential component of the relative velocities (since the tangential component is shared).

What you are saying is that, if I consider a photon, that symmetry doesn't exist.

Is that so? (Not trying to be a smartarse, just trying to confirm that this is what you are saying. I am not necessariliy saying that the symmetry is something that we categorically must have.)

cheers,

neopolitan
