Why is the line of sight not as fast as the speed of light? Is the speed of sight faster than the sp

That's a real question.

What do you mean by "sight"? I'm so lonely. There is no such thing as "sight" in physics, and if you mean that you open your eyes and see something, it does not mean that your eyes are emitting any "sight", but that the light of that object is reflected into your eyes.

Then the problem is clear, whether you see the Sun or an extragalactic galaxy, it is not that your eyes are sending out a "vision" that is countless times faster than the light, but that the light has already departed a few minutes or even tens of thousands of years ago, and now it is just falling right in your eyes.

Isn't this question a little bit asked by elementary school students, biology has said what kind of organ the eye is, right? The eyes are the "light-sensitive" organs, and having eyes in an environment without light is equivalent to being blind, just like seeing nothing without light at night.

If you can see things when you open your eyes, then you should be able to see very brightly even if the lights are not turned on in our house, is that true? If the light does not exist first, the eyes have no effect, that is, the eyes are "blind", and if we do not come to us through a long journey, none of us will want to see.

In fact, should parents be asked first?

What you see is light.

What you see is a light run n light years in front of your eyes, not how many light years you can see at a glance.

What can you see at night?

Answer Black, stars?? Why.

Because your eyes can't receive light sources (electromagnetic waves), but extragalaxies emit light, why can't you see them? Because it takes time for light to reach the earth, your eyes are just an organ that receives electromagnetic waves, and electromagnetic waves are calculated in terms of wavelength, so light waves tens of thousands of hundreds of thousands of light years ago can only be seen now! For example, the ears receive sounds, and you can only hear the sound when you see someone moving their mouth in the distance with a distant vision!!

You can't go beyond the limits of the medium.

"Sight" is not a substance. It's as simple as that.

Because what the eye perceives is the reflection of light.

The speed of vision is the sensation of light reaching the human eye, conducting it from the retinoid model to the optic nerve of the person, and then forming the sensation of the image in the brain. It stands to reason that the reflex speed of a nerve should be smaller than the speed of light. But how fast this speed is, I'm afraid it's hard to measure.

After all, this reaction should be a biochemical one. It won't be faster than the speed of light. In addition, this speed also varies from person to person, some people are very responsive, some people are sluggish.

It is not possible to generalize.

The light we see in the universe is not the light of this moment, and it takes 8 minutes for the sunlight to reach the earth. Without light, people would not have a sense of vision, and seeing light is the cause of light hitting people's eyes, and seeing light is the effect. There is no such thing as "the speed of sight is faster than light" as you say.

Velocity of sight, as the name suggests, is the speed at which the eye sees an object. The eyes must use light to see objects. So, in this sense, the speed of sight is equal to the speed of light.

But through our glasses, we can see all at once that the light emitted is tens of thousands to millions of light-years away from the stars that travel to Earth, and we only see the light that came out tens of thousands to millions of years ago.

No, what you're talking about is only the light that came out of the star millions of years ago, not the star millions of light years away in an instant.

Yes The fact that a person can see things is actually caused by light entering the human eye, so it can be said that the gaze has a speed, and it is equal to the speed of light.

No, speed does not exist, and what the eye sees, if there is no reflection of visible light, the eye cannot see anything.

We see the sun when the sun's rays enter our eyes, not the "gaze" emitted by the eyes that touches the sun, so there is no concept of "gaze" speed.

We look at the Sun on Earth, and as it was said at the beginning, the rays we receive are emitted by the Sun 8 minutes ago, not "immediately". In other words, the sun we see is the sun "8 minutes ago", and if the sun suddenly "goes out", we can only see it "8 minutes later" on Earth.
