Oh honey, let me break it down for you. Quantized redshifts basically tell us the amount by which light from galaxies has been stretched as the universe expands. It's like a cosmic measuring tape showing us how the universe has grown. Scientists use this info to track the expansion of the universe and figure out its age and fate.

Where was Edwin Hubble's discovery made?

Edwin Hubble's groundbreaking discoveries were made at the Mount Wilson Observatory in California. It was here, in the 1920s, that he observed distant galaxies and established the relationship between their redshifts and distances, leading to the formulation of Hubble's Law. This work fundamentally changed our understanding of the universe, demonstrating its expansion.


What does redshifts indicate to astronomers?

The object is moving away from the observer.


What are the strengths and weaknesses of the redshift theory?

cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding


What theory is Edwin Hubble the founder of?

Edwin Hubble is the founder of the Big Bang theory, which describes the origin and evolution of the universe. His observations of galaxies and their redshifts led to the formulation of Hubble's Law, demonstrating that the universe is expanding. This groundbreaking work provided strong evidence for the idea that the universe began from a hot, dense state and has been expanding ever since.


How can scientists estimate when the big bang happened?

Scientists estimate the age of the universe and the Big Bang by studying the cosmic microwave background radiation, known as the afterglow of the Big Bang. By analyzing the temperature fluctuations in this radiation, researchers can determine the age of the universe to be approximately 13.8 billion years old.

Do quasars have large or small redshifts?

Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.


Will astronomers do all the redshifts of the 100 billion galaxies in the universe?

Perhaps in the future astronomers will do all the redshifts of the 100 billion galaxies in the universe.


Do quasars have a redshift?

Yes, very large redshifts.


Can astronomers get all 100 billion redshifts for all 100 billion galaxies in the observable universe?

No, because it will be impossible for astronomers to get all 100 billion redshifts for all 100 billion galaxies in the observable universe.


How can you list all the designations and redshifts of all 100 billion galaxies in the observable universe?

It is not possible to list all designations and redshifts of all 100 billion galaxies (cseligman.com/text/atlas/pgc00.htm)


The spectra of most galaxies show redshifts this means that their spectral lines are what?

The spectral lines of galaxies are redshifted, indicating that they are moving away from Earth. This redshift is typically a result of the expansion of the universe, causing galaxies to move further apart.


How does the expansion of the universe create redshifts?

As the universe expands, the space between galaxies also expands, causing their light to stretch out as it travels through this expanding space. This stretching of light waves results in redshift, where the wavelength of light increases, shifting it towards the red end of the spectrum.


What two quantities did Edwin Hubble compare to discover the expansion of the Universe?

Edwin Hubble compared the distances to galaxies (based on their brightness) and their redshifts (due to the Doppler effect) to discover the expansion of the Universe. By finding a relationship between these two quantities (dubbed Hubble's Law), he provided evidence that the Universe is expanding.

Will astronomers measure redshifts of 100 billion galaxies in the observable universe?

No. We do not have time to make so many measurements.


Is it impossible to do all the redshifts of the 100 billion galaxies in the observable universe?

Yes. To image, catalog, and calculate the redshift of each galaxy individually would take an extremely long time. In order to complete the work in 100 years we would need to measure redshifts at a rate of more than 30 galaxies per second.


The spectra of most galaxies show redshifts this means that their spectral lines?

have wavelengths that are longer than normal:)
