Not everything is moving away from us. The farther an object is away from us, the greater the affect of the expansion. At the distances within galaxy clusters the effects of expanding space are rather small. It is only galaxies in other clusters that are moving away from us. In terms of intergalactic space, the Andromeda galaxy is very close to us, so any effects of cosmic expansion are negligible. At such a distance, the gravitational attraction between the two galaxies has a much stronger influence.
What else can I help you with?
Why is the light blue shifted in the Andromeda galaxy?
The light from the Andromeda galaxy is blue-shifted because the galaxy is moving towards us due to the effects of gravity and the expansion of the universe. This motion causes the wavelengths of light emitted by the galaxy to appear slightly compressed towards the blue end of the spectrum.
How far away is a star on the near side of the Andromeda galaxy from earth?
A star on the near side of the Andromeda galaxy is approximately 2.537 million light-years away from Earth. This distance is constantly changing due to the expansion of the universe.
What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
Which view of the fate of the universe is currently favored a big crunch or an endless ever expanding universe?
Answer: I don't believe that any consensus has been reached, although it seems that more people are arguing that a "big crunch" is more likely that an endless expansion into increasing entropy. But this is definitely a question that you should ask again in about 15 years. Answer number 2: The ever-expanding Universe. The main reason this seems likely is that it has been observed that the expansion of the Universe is actually accelerating - i.e., it is expanding faster now than in the past. Answer number 3 : I agree with answer 2. The discovery of "dark energy" and the increasing rate of expansion of space favors the ever expanding Universe.
Observation of the red shift of galaxies suggest that the universe is what?
Expanding Or that the light is exiting a gravity hole (star).
What is the universal expansion?
Edwin Hubble discovered our universe was expanding from his observations of extragalactic nebula (other galaxies) from the Mt. Wilsom Observatory. His discovery was announced in 1925. What Hubble discovered was that the further a galaxy is from ours, the faster it is receding. Albert Einstein would have received credit for the discovery of the expansion of the universe had he not tinkered with his equations for General Relativity to fudge a "static" universe. This expansion is the expansion of intergalactic space itself. Our local space is not expanding. In fact, Andromeda, our sister galaxy, is actually approaching us. But the furthest galaxies we can see are moving away at a pretty good clip. If you would like more information on this, you might look up the "balloon" analogy.
Is the universe still expanding?
Yes, and the expansion is accelerating - it is expanding faster and faster.
Why is the light blue shifted in the Andromeda galaxy?
The light from the Andromeda galaxy is blue-shifted because the galaxy is moving towards us due to the effects of gravity and the expansion of the universe. This motion causes the wavelengths of light emitted by the galaxy to appear slightly compressed towards the blue end of the spectrum.
The expanding of matter when it is heated?
thermal expansion
Is expanding a chemical or physical?
Expansion is a physical property.
Which theory is also known as expansion theory?
The expanding universe model
Is the universe all expanding outward from one central location?
Wherever you are located, it seems as if you are at the center of the expansion.
What is meant by the expansion velocity of a galaxy?
The speed at which a galaxy is expanding/getting larger.
What is the verb for expanse?
The verb for expansion is expand.Other verbs are expands, expanding and expanded."We will expand the empire"."Her horizons were expanding"."His education has expanded his knowledge".
What are examples of thermal expansion of a liquid?
Examples of thermal expansion of a liquid include water expanding as it is heated, causing liquids like mercury in a thermometer to rise when exposed to heat, and gasoline expanding in a fuel tank on a hot day.
What were the reasons for the imperial expansion 1870-1900?
America's expansion in the 1900's was because European countries were expanding. America hoped to match them.
Is the universe curve and for ever expanding?
The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past). It may be reasonable to assume that this trend will continue in the future, but it would also be a little premature to be completely sure.The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past).
