Isn t what we see real?

It's not ridiculous, human beings are always self-righteous, but they don't really understand anything, it's like the same thing, and it can be very different from that perspective, and I think what you're saying makes a lot of sense, it's a little bit idealistic.

Yes, it is mentioned in the theory of relativity that light is distorted by gravity and keeps moving in a curve in the universe, which is both closed and not closed, and the universe is like a big black hole, in which light constantly circles and cannot escape. But this is still a problem that scientists are studying, so let's just find out. There is nothing wrong with you saying that light in real life is not an absolute straight line, but as mentioned earlier, light is distorted in the cosmic space, which is a very large and very large space, and it can be said that the curvature of light is distorted very, very small, so we think that light is a straight line on the earth and even in the solar system, and the error is so small that it can be completely ignored.

In addition, with this in mind, the reflection of light is not difficult to understand. It's a reflection, but I think it's okay to think of it as if it's shining brightly, and that's how I understand it, it's just a conceptual distinction. When light enters the eye, the image is exactly what the original object looks like, but it is inverted, but although it is an inverted image, due to human habits, the electrical signal transmitted by the eye nerve will also transmit the signal that turns it into a positive image to the central nervous system.

What a person sees is the image of the original thing that has been shrunk. There is no deviation. As for your conclusion, you can't say that you are wrong, but it shows that you are good at thinking, which is good.

These are personal opinions, please advise if you make mistakes.

Just squint, not nearsighted? You're happy. Knowing that your eyes are not good, you should protect them well. If the hospital can't find anything, you can only rely on yourself to pay more attention.

After so many years, it is very likely to lead to myopia!

It's just some sequelae, but you don't protect your eyesight, which causes your right eye to see more and more blurry, and the sequelae are singled out. You have to protect your eyes and go to the hospital for more check-ups, and the situation will improve.

In the 21st century, the value of knowledge will become more and more important, for example, Hu Wanlin spread rumors in China that he could make water become oil, and became a billionaire overnight, which is why, it should be the lack of knowledge of the Chinese people, now, junior high school students know that the water molecule is H2O and the main component of gasoline is C 4 C 12 hydrocarbons, which is one of the mixed hydrocarbon items, and it is impossible to transform, which is not one of the values of knowledge? Seek adoption.

If it doesn't work, then what is a university for?

As the saying goes, "learn from the old and learn the new".

Your friend said that the knowledge in the book is useless because it cannot be exchanged for "money".

But is it true that knowledge can't be exchanged for money?

Vary. Montaigne said, "The ignorance of a beginner lies in not learning, while the ignorance of a scholar lies in the aftermath." ”

I heard the older generation say that dogs can see things that we can't see, don't worry, it's generally okay because no one can confirm it, so I don't know if it's true, but you're not more afraid, because there is a dog in it doesn't dare to approach, dogs are quite smart, but legends are always legends, don't worry.

A lot of dogs bark inexplicably, even if it's not clean, the landlord has a clear conscience.

Have you ever wondered what you might have heard? But dogs have better hearing than people, so maybe there's something you don't hear and the dog notices.

We can see things because light enters the human eye and the light travels in a straight line in the same homogeneous medium, while objects that do not emit light themselves enter the human eye by reflecting the light source. So we can also see objects that don't emit light!

The problem is confusing. Discovery is learning something you didn't know before. Everyone's unknown territory will be different, but the sail chain has to look at the sun stool to find out.

I found that the men of the earth are basically fighting for the sake of women, and women are ruling this world by controlling men! Whether you believe it or not, my brother believes it anyway.

Does inertia have anything to do with whether or not you can see something?

Of course, we can see things because light enters the eye, and it has nothing to do with whether the object has inertia or not.

Without inertia, you have to redefine the way objects move.

Whether you can see something or not is probably related to the reflection of light.
