How does light from distant galaxy . galaxy out side of 32000000 light years support the big bang theory?
The light from distant galaxies is redshifted. The only reasonable explanation for that is that the galaxies are moving away from us.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
How does redshift support the notion of the expanding universe?
The redshift of distant galaxies is believed to be a result of the Doppler effect - in other words, the light is shifted towards lower frequencies ("redshifted") due to the fact that the galaxies move away from us.
Why do light waves from distant objects appear to be stretched?
Light waves from distant objects appear stretched due to the expansion of the universe, known as cosmological redshift. As galaxies move away from us, the wavelength of the light they emit is stretched, causing it to appear more redshifted. This phenomenon allows scientists to determine the distance and speed of objects in the universe.
When the spectrum of light from a star is Redshifted the star must be what?
When the spectrum of light from a star is redshifted, it indicates that the star is moving away from the observer. This is due to the Doppler effect, where the wavelengths of light stretch, causing them to shift toward the red end of the spectrum. Redshift can also suggest the star is part of an expanding universe, as seen in distant galaxies. Overall, redshift is a key indicator of the star's velocity relative to Earth.
Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
What did the result of analysis of the spectral lines of the five galaxies reveal about their motion relative to earth?
The analysis of the spectral lines of the five galaxies revealed that their light is predominantly redshifted, indicating that they are moving away from Earth. This redshift is a consequence of the Doppler effect, which shows that the galaxies are receding due to the expansion of the universe. The degree of redshift also provides insights into their velocities, with more distant galaxies typically exhibiting greater shifts, supporting the theory of an expanding universe.
The visible part of distant galaxies is the galaxies'?
The visible part of distant galaxies is the collection of stars, gas, and dust within the galaxy. These components emit light that reaches our telescopes, allowing us to observe and study the structure and properties of the galaxies.
What diagram best represents the pattern of spectral lines from the same element when it was observed by Edwin Hubble in the light of one of the distant galaxies?
The best diagram to represent the pattern of spectral lines from the same element observed by Edwin Hubble in the light of distant galaxies is the redshift spectrum. This spectrum shows the spectral lines of elements shifted toward longer wavelengths (redshifted) due to the Doppler effect, indicating that the galaxies are moving away from us. The pattern of these lines remains consistent with the element's known absorption or emission spectrum, but the entire set of lines shifts uniformly to the red, reflecting the expansion of the universe.
What does the light from distant galaxies show red shift?
The light from distant galaxies shows redshift because the universe is expanding. As the galaxies move away from us, the light they emit gets stretched, causing its wavelength to increase and shift towards the red end of the spectrum. This redshift can help scientists determine the velocity at which galaxies are moving away from us and provide insights into the expansion of the universe.
How red shift connect with universe expanding?
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
Why is the night sky dark?
The night sky is dark because the light from distant stars and galaxies is not enough to illuminate the entire sky. This phenomenon is known as Olbers' Paradox, which suggests that the universe is not infinite and has a finite age.
