    I think it's impossible to emit light, but it can reflect light, because the human body doesn't have a light source, how can it shine.

    Attempts can be made to transfer the glowing gene to its original gene. With GMO technology, this can be done.

    Everything emits a luster outward, and so does humans, it's just too weak to see.

    Because it has genes that make it glow, it glows.

    So I want to make the species that don't shine shine.

    It can't be, the other glowing one shines because it has genes that make it glow.

    That's impossible, man can evolve and is a very adaptable animal, but for the time being, human eyes have no reflective film, so they can't be like cats and other animals that have glowing eyes at night and super vision in the dark! Therefore, even if a person (temporarily evolutionary) lives in the dark for a long time, his eyes will not be able to shine.

    No, it seems that many animals have a layer of reflective substance on their retina that humans don't.

    Reflections and glows are not clear?

    1 All of this may be similar to the effect of luminous contact lenses, if the pure human eye (whether it is the cornea or the lens) is impossible to glow, even if the night vision is very good, the reason why we can see the owl's eyes at night is because of its special sclera and lens structure, which is very different from humans.

    Cats can't see in complete darkness, but in dim conditions, cats' night vision is much better than that of humans or other animals, and the main reason is the cat's eye structure.

    If you look at the proportion of the size of the cat's head diameter, the cat's eyes account for a large proportion of the size of the cat's head. The structure of the eyeball is made up of many layers. The white part, called the sclera, is a very tough layer of blood vessels that transport oxygen and nutrients to provide the eye with the nutrients it needs.

    The transparent part is called the corneaThis part is made up of a thin monolayer of cells, so it is quite clear and transparent, and light can enter the inside of the eye without hindrance.

    Cats can open the iris on their pupils very wide, allowing as little light as possible to enter the eyeballs for the purpose of seeing.

    As for the retina of animals, it is composed of two layers of tissue: the cells of the light-sensing layer are called rods and cones, and when light enters the eye, they will be rod cells, and then the rod cells will amplify the reaction of these rays, like an amplifier of sound. And because cats have more rod cells, the effect of light amplification is also better, in humans about 4 5 (80%) of the photoreceptor cells are rod cells, but in cats it is 25 26 (for rod cells.

    Therefore, the proportion is relatively high.

    In addition, the felt layer at the bottom of the cat's eyeball, tapetum lucidum, which is found on the eyes of deer and raccoons, is the reason why these animals' eyes glow when exposed to strong light (such as car lights) at night.

    In layman's terms, there is a kind of light-concentrating substance in the eyes of felines that can gather the faint light in the environment and use it to see things, so we often see that the animals in ** will have white eyes.

    The human eye can see objects and needs the reflection of light, and in an environment that is completely dark and completely devoid of light, there is no reflection of light into the human eye, so people cannot see objects. For example, if a person is in a sealed underground bomb shelter, he cannot see anything because there is no light.

    No, no light is reflected through the object to your eyes, and your eyes can't shine, so you can't see it.

    You can't see anything, and if there's no light at all, there's no light coming into your eyes, and you can't see anything!

    Kindness... You've got a lot of imagination! Eight wrongs, eight mistakes! You go buy a low-light night vision device and your wish is granted.

    Of course you can, but not right now, after a while. How long, I'm not sure. Just wait.

No. Because a wormhole is only two spatial connection points in one world, and there is only one world, it is impossible for humans to enter another world after finding the wormhole.

There is no accurate number, and now humans have observed galaxies 13 billion light-years away, not yet to the edge of the universe, although they have observed so far away, do you think they can see everything in 13 billion light-years? It's impossible, they just received the light emitted from 13 billion light-years away, that's all, and this light, it's been 13 billion years, they are looking at the universe 13 billion years ago, to put it bluntly, everything depends on estimates, everything depends on guessing, anyway, they now estimate that the entire universe has a diameter of 96 billion light years, this is because they speculate that the universe 13 billion years ago was only 1 billion years old according to the light 13 billion years ago, that is, the current universe is 14 billion years old, Then, according to their estimation of the expansion rate of the universe, it is estimated that the universe has a diameter of 96 billion light years, of which there are more than 2 trillion galaxies, which is a large galaxy like the Milky Way, not the solar system.

Absolute silence means that one cannot hear any outside sounds, only the sounds inside one's own body. People can't communicate in such an environment, and there will be a certain amount of anxiety in their hearts, so humans can't adapt to it.
