The discussion centers on the structure of photons and their implications for deciphering interstellar messages. A photon is described as having a disk-like shape, being a few tens of millimeters long but spanning vast distances. The conversation explores the concept of photons existing in a multi-dimensional hyperspace, suggesting that they represent closed reactions that traverse the entirety of space-time. The majority of a photon's history is confined to a small four-volume of space-time, with its electromagnetic force diminishing rapidly outside this area, following a Gaussian distribution. The idea is presented that while photons may behave probabilistically, they possess a real existence, challenging conventional views. Additionally, there is curiosity about the Cosmic Microwave Background Radiation (CMBR) and its potential for universal density measurements and insights into dark matter effects.
