Is it that the greater the redshift, the farther the distance

The distant celestial bodies described by Hubble's law look like this. The greater the redshift of the light they emit, the farther away from us, which is important evidence of the great cosmology.

The redshift is a manifestation of the relative velocity of a celestial body with us. The larger the redshift, the greater the regression velocity of the celestial body relative to us.

In fact, some celestial bodies at close range do not conform to this law, because their velocity relative to us is randomly changed, and some even have a blueshift due to their movement in the direction close to us, so their distance cannot be determined by redshifting, only their relative velocity with us.

No, a large redshift can only indicate that the relative separation velocity is large, but the farther the distance between stars in the universe, the greater the separation velocity (redshift) is the basic law, which is in line with the result of the great ** theory.

Basically, you can think so. The facts of current observations also show that the greater the distance, the greater the redshift; The greater the redshift, the farther the distance.

First of all, it's not entirely true, the larger the redshift, the greater the distance away from the unit time.

Well......I guess it represents the speed at which the universe is expanding! The speed is fast, and the natural distance is greater over time! On the contrary, the contraction of the universe is a blue shift! It's just that the speed is different from each other!

No. It can also be a gravitational redshift.

Even the redshift caused by relative motion may not be caused by the expansion of the universe.

In regions where the expansion of the universe is dominant (more than 1 billion light-years from Earth), so to speak.

In 1929, the American astronomer Hubble discovered that the spectrum of a celestial body moves like a long-wave redshift, and derived the law of redshift, also known as Hubble's redshift. The law of redshift is the Doppler effect of light, which means that when you observe a celestial object at high speed away from the earth with a telescope, its spectral color will move closer to red, which is called redshift.

I was right!

Because redshift is an optical phenomenon. Stars emit rays and are received by people. Distances can be determined by means of infrared light. Then after getting the distance, it is compared with the previous one, so it is judged.

The redshift has nothing to do with the orbit, which does not change. Cosmic expansion refers to a phenomenon of spatial motion at the edge of the universe that causes certain stars (and their orbits) to move, rather than because of the stars themselves.

The question is what makes them move in a circle, and why they are so precisely synchronized that they can go around together like accomplices. Normally, it should be some far away and some closer.

Therefore, if this is used as an explanation for the redshift of distant stars in the universe, it is at least full of flaws, if not incredible.

If redshift is to be true, we must first prove that the universe is constantly getting infinitely larger. If the universe is always getting infinitely larger, then redshift is correct. For example, if you draw two dots on a balloon, if you blow the balloon bigger and bigger, the two dots will get farther and farther apart.

The universe is the same, if the universe becomes infinitely larger, then each planet will be farther and farther away, then the redshift is correct. Of course, these are my own opinions.

Redshift refers to the phenomenon that the wavelength of electromagnetic waves emitted by celestial bodies increases when they move in the direction of moving away from the Earth.

To put it simply, redshift is the evidence that the corresponding planet is gradually moving away from us, and it is also the proof of the grand theory of the universe. If the corresponding galaxy is moving closer to us, its radiation shifts in the direction of short waves, commonly known as blueshift, that is, the wavelength that moves in the direction of blue light. The faster you get closer to us, the greater the blueshift.

Conversely, if the galaxy is moving away from us, its radiation shifts in the direction of the long wave, which is also known as the redshift, that is, the wavelength that moves in the direction of the red light. Again, the faster away from us, the greater the redshift.

In a popular example, if you are walking on the road and you drive an ambulance with a horn, the closer the car gets to you, the more sharp and rapid the whistle becomes, and when the ambulance is far away from you, the whistle becomes slow and muffled. It's just that the sound waves change in the direction of the short wave and the direction of the long wave as they move closer to you or away from you, and the redshift and blue shift of the light wave are the same thing.

The frequency of different colors of light is different, and the spectrum is obtained by arranging the light rays of different colors continuously from small to large (or from large to small) according to the frequency.

According to the Doppler effect, when the light source and the object receiving the light have relative motion, and when they are far away from the object receiving the light, the frequency of the light received by the object is shorter than the frequency of the actual light, because the frequency of red light is shorter than that of blue light, so the light emitted by the light source will shift in the direction of red light in the spectrum, which is called red shift. When the light source and the object receiving the light have relative motion, and the light source is close to the object receiving the light, the frequency of the light received by the object is longer than the frequency of the actual light, and since the frequency of red light is shorter than blue, the light emitted by the light source will shift in the direction of blue light in the spectrum, which is called blue shift.

Light is seen here as a wave.

Redshift and blueshift are said to be the frequency of light that changes, the former becomes lower and the latter becomes higher, i.e., blue light is higher than red light.

The two are not necessarily related to light and dark, which refers to the intensity of light, that is, the square of the amplitude.

In practice, the redshift and blueshift of light can only be clearly observed at large-scale distances in astronomy, and we cannot usually access them. Since only stars that are extremely distant are redshifted due to the expansion of the universe, they tend to be fainter because of their distance.

Essentially affects the frequency, with the red shift becoming low and the blue shift becoming high. The luminous flux also decreases to high with frequency.

It's been a long time since I graduated from high school, so don't blame me for not answering well.
