Was there light before the stars?
Before there were stars, there was matter and radiation. Before there were neutral atoms, there was an ionized plasma, and when that plasma forms neutral atoms, those allow the Universe to deliver the earliest light we see today.
What type of light was the first in the universe?
The first time that photons could rest for a second, attached as electrons to atoms. It was at this point that the universe went from being totally opaque, to transparent. And this is the earliest possible light that astronomers can see. Go ahead, say it with me: the cosmic microwave background radiation.
What was in the universe before stars?
There were no stars, and there were no galaxies. After the Big Bang, the universe was like a hot soup of particles (i.e. protons, neutrons, and electrons). When the universe started cooling, the protons and neutrons began combining into ionized atoms of hydrogen and deuterium. Deuterium further fused into helium-4.
Was there light at the beginning?
Straubinger on the subject of inedia. Straubinger visits several people who supposedly nourish themselves with “light” and tries to find possible explanations on how inedia might work. Straubinger researched inedia for ten years….

How was light formed in the universe?
During the first three minutes of the universe, the light elements were born during a process known as Big Bang nucleosynthesis. Roughly 380,000 years after the Big Bang, matter cooled enough for atoms to form during the era of recombination, resulting in a transparent, electrically neutral gas, according to NASA.
What was that light before the sun Genesis 1 3?

When did the stars light up?
Astronomers have worked out when the first stars began shining. They say that this period, known as the “cosmic dawn,” occurred between 250 to 350 million years after the Big Bang.
When was light created?
In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light.

What is primordial light?
Primordial Light is the name given to the oldest light in the Universe—the 13.7 billion-year-old photons that come to us from the Big Bang.
How did the first stars form?
Over time, gravity slowly shepherded the densest regions of hydrogen gas into compact clouds, which ultimately collapsed to form the first stars. When these primordial stars first began shining within the pitch-black void, they blasted the surrounding hydrogen gas with ultraviolet radiation.
