For the photons which began to travel in the universe since the big bang there must exist a space. Would this space has been created by a fundamental wave which propagates at the same speed, c? And if so, what do we call this possible wave, let's say creator of space?
Mr. Jamil Kooli
Photons emerged during the early universe, dominating its energy during a period known as the Photon epoch after the Big Bang. As the universe expanded and cooled, around 370,000 years later, conditions allowed for the formation of neutral atoms. This resulted in photons interacting less with matter, leading to the universe becoming transparent and the generation of cosmic microwave background radiation, marking a significant phase in the universe's history.
The cosmic microwave background radiation we observe today is a faint remnant of this early era, originating from the recombination period about 378,000 years after the Big Bang. This radiation represents the universe when it first became transparent to radiation.
As for the space through which photons travel, it's not caused by a specific 'creator wave.' Instead, space itself expands, allowing photons to propagate through it at a constant speed known as 'c,' the speed of light. This expansion of space is a fundamental feature of the universe's evolution, and it's this expansion that provides the 'space' for photons to travel without needing a specific 'creator wave.'
Regarding your query about the radius till now, the current observable universe's radius extends to the distance that light has had the time to travel since the Big Bang, which is approximately 13.8 billion light-years. However, it's important to note that the universe itself might be larger than this observable limit due to the expansion of space over time.
Moreover, there are no observable remnants of the photon age now, but what we see from the cosmic microwave background radiation is a faint remnant of the reconnection epoch that occurred about 378,000 years after the Big Bang, and not from the photon epoch at that time. About 10 seconds after the Big Bang.
