What would the universe look like from the perspective of a photon observer?

SUMMARY

The discussion centers on the concept of a photon observer's frame of reference in relation to Einstein's theories of relativity. Participants agree that no valid frame of reference exists for a photon, as it travels at the speed of light (c), rendering traditional measurements of time and distance meaningless. The conversation highlights that as one approaches the speed of light, time dilation occurs, leading to a scenario where time effectively stops for a photon. The impossibility of accelerating any object to the speed of light is emphasized, reinforcing the notion that questions regarding a photon's perspective are fundamentally flawed.

PREREQUISITES
  • Understanding of Einstein's Special Relativity principles
  • Familiarity with the concept of inertial frames of reference
  • Knowledge of time dilation and its implications at relativistic speeds
  • Basic grasp of the speed of light as a universal constant (c)
NEXT STEPS
  • Study the implications of time dilation in Special Relativity
  • Explore the mathematical framework of Lorentz transformations
  • Investigate the concept of massless particles and their behavior in physics
  • Examine cosmological theories that propose variations in the speed of light over time
USEFUL FOR

Physicists, students of relativity, and anyone interested in the fundamental principles of light and motion in the universe.

There was a time when people a lot more qualified than me said the Earth was the only valid frame of reference. So the age of geocentricity was born. It started with Ptolemy (a most qualified and eminent scientist of the 2nd century A.D) and lasted for over 1500 years because everyone believed Ptolemy without question. It scares me when people are so sure of themselves and the status quo that they cannot afford to explore the places where conflictiing theories (GR and QM, for instance) might merge. Thank heaven Copernicus came along and dared to ask a question, to reach a little bit outside the box. Now I know I'm no Copernicus. In fact I would go so far as to say that I'm an idiot--a fool if you like. But I am wise enough to know that GR, SR and QM are missing something. Einstein, the author of GR knew that as well and I think he would object to your unquestioning, and wonder-crushing self assuredness. He would encourage me to keep asking questions and to keep up the search for the truth. I don't pretend to think I will be the one to find missing truth. But I'll certainly continue to have fun looking.

I see someone beat me to locking this thread. Let me point out, that we are not attempting to push the state of the art here at PF, and that this is mentioned in our guidelines, which I encourage people to read (click on 'rules'). People with personal theories to discuss need to find another forum, we are interested in explaining physics as it is currently understood to a general audience here, and not in pushing the state of the art or providing a soapbox for everyone with some pet personal theory.

Unfortunately, advancing the state of the art of physics is not as easy as it might appear to someone who lacks expertise in the field. Unfortunately, not only do grandiose proposals generally fail when subjected to close scrutiny, they are rarely even original :-(.
