Red Shift

The red shift spectra of galaxies show that most galaxies are moving away from us, indicating that the universe is expanding. This observation supports the Big Bang theory, which suggests that the universe began in a state of high density and temperature and has been expanding ever since. The amount of red shift in a galaxy's spectrum can also provide information about its distance from us and its velocity.

Scientists use the red shift of light from distant galaxies to measure their distance from us. By measuring the rate of expansion of the universe using red shift data, scientists can calculate the age of the universe, known as the Hubble time, which is currently estimated to be around 13.8 billion years.

The short answer to this question is "everywhere".

Redshift is one aspect of the Doppler effect of light. An observer, looking at an object that emits light, will see the apparent wavelength of that light either compressed to shorter values (if the object is moving toward the observer) or stretched to longer values (if the object is moving away from the observer). Since red light has a longer wavelength than blue light, a stretched wavelength is referred to as a "redshift".

It turns out that all of the galaxies in the Universe are moving away from our galaxy, save for a few that are gravitationally bound together into the Local Group of galaxies to which the Milky Way belongs. Therefore, in every direction you look, the sky is full of redshifted galaxies.

Within our galaxy, stars have random motions in addition to their general orbits around the galactic center. Some of those motions result in blueshift, some in redshift. So you can find blueshifted stars in every direction you look. But the stars are very local, distance-wise, compared with the redshifted galaxies.

Scientists can observe red shift using a spectrometer or a telescope equipped with a spectroscope. The spectrometer will measure the shift in wavelength of light emitted by celestial objects, which can indicate the red shift. Additionally, precise and sensitive telescopes are needed to capture high-quality data for accurate red shift measurements.

Mid shift can be any time frame that usually includes mostly hours of darkness (depending on location). Most military "mid shifts" are 8-12 hours long. I currently work from 2300-0800 (11pm-8am) for mid shift. Sometimes it is 2400-1200 (12midnight-12 afternoon). Although hours will vary, it usually consists of working during the night.

D shift is a work schedule where employees work during the daytime hours, typically starting in the late morning and ending in the early evening. It is one of the common shift schedules used by companies to ensure coverage throughout the day.

Christian Doppler, an Austrian physicist, is credited with discovering the phenomenon of the Doppler red shift in 1842. He observed that the pitch of sound waves from a moving object changes depending on the object's motion relative to the observer. His theory was later extended to light waves to explain the red shift observed in the spectra of distant galaxies.

Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.

Red-shift is used today in astronomy to determine the distance and speed of celestial objects such as stars, galaxies, and other cosmic phenomena. It helps scientists understand the expansion of the universe and track the movement of objects in space. Additionally, red-shift is used in various fields of science to study the Doppler effect and analyze the movement of objects relative to the observer.

The red shift in stars was first discovered by astronomer Vesto Melvin Slipher in the early 20th century. He observed that the spectral lines of distant galaxies were shifted towards longer wavelengths, indicating that these galaxies were moving away from us.

No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.

All modern models based on science that are worth their salt would be. The only major theory I know about the origin of the universe is the Big Bang Theory, which is supported by Red Shift observations.

Galaxies we can observe are all moving away (we know this due to Red Shift) from a central point, believed to be the epicenter of the Big Bang.

Most of the more distant galaxies appear to be red-shifted, indicating that they may be moving away from us. (Some, like the Andromeda galaxy, are blue-shifted, indicating that they are moving toward us. In fact, the Andromeda galaxy will probably collide with the Milky Way in about 4 billion years or so. )

Because distant galaxies in every direction are red-shifted, many scientists speculate that the universe itself is expanding, and carrying those distant galaxies away. The further away they are, the faster they seem to be moving, which reinforces the "universal expansion" concept.

Given that the entire field of astrophysics is less than 150 years old, I suspect that there may be more going on than we currently believe, and that our descendants six generations hence will wonder "What were they thinking?" So keep your minds open, and don't think that there isn't anything new to be learned.

The red shift does not expand the universe. The red shift is an indicator that the universe is NOT Expanding. The red shift is an indicator of the centrifugal ( outward) force needed to balance the centripetal ( inward) force of gravity or electrical attraction. The earth has a redshift v/c= 30k/300M= 1/10000 = cos(V).

This indicates the earth is balancing the centripetal force towards the sun witht centrifugal force away from the sun the angle is 89 degrees 59 minutes and 39 seconds. This angle is enough to balance the centripetal and centrifugal forces.

The redshift is related to the "Dark Energy" Astronomers have looking for. The "Dark Energy" is in plain view, it is the momentum energy, cP=cmV, the earth's momentum mv also creates energy cmV, a vector energy cP. The Divergence of this energy is the centrifugal force, cDel.P= -cmv/r cos(V) = mv/t cos(V)= the centrifugal force. The gravitational centripetal force is mv2/r. When these forces are balanced mv2/r= cmv/r cos(v) gives v/c= cos(V) the redshift.

The larger the gravitational force the larger the redshift. This is so because the velocity v gets larger v=(GM/r)1/2 and the closer the smaller r gets the larger the velocity and the larger the redshift, v/c. This indicates contraction!

Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then

(size of universe at redshift z)/(current size of universe)= 1/(z+1)

Cosmic background radiation is the residual radiation left over from the Big Bang, which fills the entire universe uniformly. Red shift, on the other hand, is the phenomenon where light from distant objects in space is stretched to longer (redder) wavelengths due to the expansion of the universe, indicating that these objects are moving away from us.

Let's begin by analogy with sound waves. You may have stood by a railroad crossing while an approaching train was sounding its horn. As the horn passes you, you'll note that the pitch of the sound (= frequency of the sound wave) changes to a lower tone. What's happening is that, as the horn approaches you, it moves a bit closer to you as it emits each peak of the sound wave's frequency, thus crowding the peaks of the waves closer together and increasing the frequency, which your ear hears as a higher pitch. As the horn moves away from you, the opposite happens -- the horn moves a bit farther away as it emits each peak of the sound wave, thus stretching out the frequency and presenting a lower pitch to your ear.

Light waves do the same thing; it's just that the speeds required to make a significant change in the frequency of the light wave (= the color of the light) are much higher than with sound. As an object emitting light approaches, the frequency of the light is higher than it would be if the object was at rest relative to you -- and the frequency of the light is lower than the rest frequency if the object is moving away.

Since blue light has a higher frequency than red light, frequency increase is referred to as "blue shift" and frequency decrease is called "red shift", regardless of the actual colors of light involved. So even radio-frequency waves can be "redshifted".

How can this be measured? It turns out that each chemical element emits its own pattern of very specific, narrowly-defined frequencies of light when heated to incandescence. We can measure those frequencies in a laboratory, and then compare them to the frequencies that we actually measure from those same chemical elements in the light coming from a galaxy (hydrogen, for example, has a strong and easily-recognized pattern of frequencies).

Knowing what the frequency was in the laboratory, and measuring the frequency as it comes from a galaxy, gives the numbers we need to plug into a formula to calculate how fast the galaxy is moving along the line of sight from us to the galaxy. If the galaxy light's frequency is higher (blue shift), the galaxy is moving toward us -- the amount of the difference between the laboratory light and the galaxy light frequency tells us exactly how fast. Similarly, redshifted light from the galaxy (by far the more usual case) tells us how fast the galaxy is moving away from us.

Red shift indicates that other galaxies are moving away from us, implying that the universe is expanding. This phenomenon is a key piece of evidence supporting the Big Bang theory. The amount of red shift is used to determine the distance and speed at which other galaxies are moving relative to us.

The red shift of visible light waves is used by astronomers to determine the speed and direction of celestial objects moving away from Earth. This phenomenon is a key indicator of the expansion of the universe and helps scientists understand the distance and movement of galaxies and other cosmic bodies.

The red shift is caused by the Doppler effect, which occurs when light waves from an object moving away from an observer get stretched, causing them to appear more redshifted. This effect is commonly observed in astronomy when measuring the motion of galaxies and other cosmic objects.

A red shift in the spectrum of light from an object indicates that the object is moving away from the observer. This is a result of the Doppler effect, where the wavelengths of light are stretched as the object moves away, causing a shift towards the red end of the spectrum.

A red shift in a star's spectrum indicates that the star is moving away from us. This is due to the Doppler effect, where the wavelength of light is stretched as the source moves away, shifting it towards the red end of the spectrum. This can be used to determine the star's velocity and direction of movement.

Edwin Hubble's discovery of red shift demonstrated that galaxies are moving away from each other, providing evidence for the expanding universe. This discovery supported the Big Bang theory and fundamentally changed our understanding of the universe's structure and evolution.

A red shift indicates that an object is moving away from the observer. This is a result of the Doppler effect, where light waves are stretched as an object moves away, causing them to shift towards the red end of the spectrum. Astronomers can use red shifts to determine the speed and direction of an object's movement.

Redshift measure the recession speed of stars and galaxies. These speeds are proportional to distance--the farther a star or galaxy is from a given location in space, the faster that entity is moving away from that location. This proportionality is given as Hubble's Law. In general, everything is moving away from everything else, and the furthe away, the faster the acceleration (local movements not included).
