How are photons created and what is their role in the universe?
Photons are created when electrons in atoms move to lower energy levels, releasing energy in the form of light. Photons play a crucial role in the universe by carrying electromagnetic force, enabling light and other forms of electromagnetic radiation to travel through space, and allowing us to see and interact with our surroundings.
Are photons omnipresent?
Yes, photons are everywhere in the universe. They can travel through empty space and are emitted by all sources of light, such as stars and light bulbs. Ultimately, they are a fundamental building block of electromagnetic radiation.
What is made up of photons?
The photon is the force carrier of the Electro-magnetic spectrum hence any wave length in it is photons. From gamma rays to Radio waves all photons.
A beam of light is made of?
A beam of light is made of photons, which are massless particles that carry electromagnetic energy. When a light source emits photons, they travel in waves at the speed of light, illuminating their surroundings.
How long have these microwave photons have been traveling through space?
Microwave photons from the cosmic microwave background radiation have been traveling through space for approximately 13.8 billion years, since the early universe.

What is all of the matter in the universe made of?
quarks and leptons, held together by gluons, W+ bosons, W- bosons, photons, and gravitons
When the universe turned transparent?
About 377,000 years after the Big Bang, the density of matter and photons in our Universe dropped to the point where photons were no longer likely to blast electrons away from nuclei. At this point, photons could travel freely throughout our Universe, which meant our Universe had become "transparent" to light (it had previously become transparent to neutrinos). The photons that became free to roam eventually reached our Earth, and are now seen as the CMBR.
Where can you find an explanation of photons?
One can find an explanation on photons online on websites, such as Universe Today, Wikipedia and Science World. Photons are elementary particles of light.
What happened 3800000000 years after the big bang?
Approximately 377,000 years after the end of inflation, the density and temperature of the proton / electron / photon "soup" had decreased to the point where, on the average, photons would no longer blast electrons from protons, when the former went into an orbital near the latter. When this happened, photons were de-coupled from the other two, and could then move freely throughout our Universe. Following that event, photons began to move from all parts of our Universe towards all other parts of the our Universe. As the photons continued to move for the next 13.7 billion years or so, space continued to expand. Thus, the wavelengths of these photons grew. At this time in the history of our Universe, all such photons have had their wavelengths expand such that they are now all microwave photons. This why all parts of our Universe now experience an almost perfectly isotopic microwave background radiaion.

Light is made of elementary particles called what?
Well, they're probably not really particles ... but they're called "photons".
When astronomers say that the universe became transparent years after the big bang what do they mean?
In the early period after the Big Bang, the universe consisted of a plasma of nuclei, electrons and photons. These protons were bound in the plasma and not free to move about. About 0.4 million years after the Big Bang, when the universe had cooled to around 4000 K, photons stopped being in thermal equilibrium with matter: the universe became transparent to photons - light could move about.
How does light form?
It is made of photons.
When did Universe - role-playing game - happen?
Universe - role-playing game - happened in 1981.
