Hydrogen nuclei fuse, immortalizing large amounts of energy, producing light.
-
Light is a kind of electromagnetic wave, any object will emit electromagnetic waves, but some can be recognized by our human eyes, some can not be recognized by the human eye, and what can be recognized is visible light.
-
Not all light can be seen with the naked eye, light is produced in the universe.
-
Light is energy, it's not that it emits light, it's that you can see it with your eyes.
-
Any matter will emit light, which is a manifestation of energy, and some light is invisible to the human eye.

There are a lot of words to say here, I'll give you a **! The Chinese translation reads it out.

Microwave background radiation is one of the four great discoveries in the history of science in the 20th century, it is the first ray of light for the birth of the universe, which can allow us to understand the secrets of the early days of the universe, determine the age of the universe, understand the density distribution of matter in the universe, the evolution of the universe, etc., it can be called the living fossil of the ancient universe, and we will understand it today.

In 2005, scientists used the Spitzer telescope to capture a ray of strange light, and through observations, scientists believed that it was a faint light from the first generation of stars that formed after the universe. These stars are very old and very far away from the Earth, and they are difficult to observe directly, however, they have left their "traces" in the "cosmic infrared background radiation". The scientific community believes that all the stars that have ever existed in the universe must leave "traces" in the "cosmic infrared background radiation".
The first generation of stars in the universe was formed about 100 million years after the "big **". These stars are the "firstborns" of the universe, and their light may contain some kind of information to tell the earliest universe to be like 13 billion years later. Astronomers have always been interested in these types of stars because they played their original role in the long path of the formation of the universe, filling the Milky Way with the heavy elements that led to life.
This ray of light is not easy to come by.
Due to 13 billion years of expansion, the universe has now become infinitely large, so the light of early stars, especially the first generation, is difficult to trace. The researchers used the most sensitive measurement methods and used the Spitzer space telescope to stare intently for 40 hours before discovering the strange light of "a little red in the green bushes". Originating 13 billion years ago, it illuminated the complete darkness of the universe and brought the first light to the universe, which can be called "twilight".
Scientists have specially processed these hard-won high-quality infrared** to obtain some seemingly "bubble" images, which are the light emitted by the first generation of stars in the universe. They are located in the constellation Draconus, which was formed when the universe was only 100 million years old. At that time, the big ** had just passed, and the universe was just an infant baby.
This ray of light stretches for 10 million light-years, and there are many bright spots along the way. That's the trail of many stars. From this, it can be judged that these stars were once surrounded by supergalaxies, and they joined together to emit this infrared signal.
Judging by the intensity of the light, it is likely that the first stars were lit up in different places at the same time, like fireworks. Because until then, the universe was pitch black, with only hydrogen clouds floating in the darkness.
The first light of the universe.

The white dwarf may have swallowed a star that was so large and unstable that it was abridged. Alternatively, the instantaneous radioactive material from the core of the red star mixes with the material in its outer layer, causing the temperature to rise. Either the reaction of helium in the outer layer and the carbon in the interior of the star causes a double **, or these two flashes are caused by the mixing of two white dwarfs**.
-
The first ray of light in the universe is impossible to see, and the big ** did produce the first light. But that's impossible to see, no matter what you use to observe! The first ray of light exists objectively, which is theoretically speaking. This is just a theory, not a reality.
-
There is nothing else at the beginning of the big **, only "light".
Why? Antimatter and positive matter meet to become "high-energy waves". The highest energy state of matter is energy itself, matter is "being" for energy, and energy is "nothing" for matter.
The "singularity" of the universe contains the whole of the current universe, and it must be the highest energy state of matter, that is, the final result of the "accretion" of black holes.
The "singularity" of the universe has only energy, which is the "nothing" of the "singularity".
When the energy can't be gathered, it needs to be **, which forms the ** initial "wave", isn't light a high-energy "wave"?
-
The light emitted by the huge energy when the big **.

Light is a way for a light source to scatter energy outward
Atoms are made up of nuclei and electrons, electrons rotate around the nucleus but have many orbitals, different orbitals represent different energy levels, when an electron outside the nucleus is excited to convert from a higher energy level to a lower energy level, the electron will release energy, there will be a corresponding photon generated, and similarly, when the transition to a higher energy level will absorb energy.
So the generation of light is the result of the transition of orbital electrons from a higher energy level to a lower energy level. The thermonuclear reaction of the sun is to constantly cause the transition of electrons around the nucleus, so the light is continuously emitted.

How did the universe come to be?
-
Because there is the sun, there is light.
1.Greet, the first rays of sunshine every morning.
2.I want to turn into the morning sun, because I think the first thing you see when you wake up is me. >>>More
Hint: A ray of sunshine in your heart can refer to the small touches around you; It can also refer to the fact that the body of a walking dead still contains humanity and also warms others; Of course, it can also be the childlike innocence that you still have in your heart that has been tainted by the world.
Topic; Sunny life in winter.
After sitting at the table for a long time, I stretched and opened the curtains to look for my white dove, but my eyes were squinted by the sudden brightness, and a large warmth was sprinkled on my face, and I raised the corners of my mouth slightly, enjoying the warmth brought by my patron saint, Apollo. Most of the time in winter, there are always dark clouds, occasionally surprised to see the corner of the sun, but quickly hidden, hidden behind the dark clouds, I can only see the dark clouds laughing wolf heart dog lungs, so the whole person has become moldy, and even smelled a little decadent breath, and now I see the sun's enthusiastic smiling face again, I naturally unscrupulous to enjoy. I like the sun on a winter afternoon, a large area of warmth but not dazzling, like a soft veil, wrapping the whole body, stretching wantonly, the winter sun gently touches every skin of my body, like a mother's hand, white and slender, the air is filled with the sweet smell of sunshine. >>>More
This happened in my family today, and I feel a little cautious.
