What piece of evidence was suggested by Edwin hubble?
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
What does it mean when an astronomers observing starlight wa spectrograph notices shift at off lines to the red end of spectrum?
This shift to the red end of the spectrum is called redshift and indicates that the object is moving away from the observer. It is a key piece of evidence in support of the expanding universe theory, suggesting that the universe is indeed expanding. The amount of redshift can also provide information about the speed and distance of the object.
Why is it difficult to estimate the current size of the universe?
It is difficult to estimate the current size of the universe because the universe curves back on itself. (Do not ask how it curves back on itself. The equations are in the Theory of Relativity by Albert Einstein.) Since no one can ever measure the distance to an edge, no way exists to determine the Universe's size.
What conclusion do astronomers make based on the red shift?
Astronomers conclude that objects in the universe are moving away from Earth due to the observed redshift in their spectra. This supports the idea of an expanding universe, as described by the Big Bang theory. The amount of redshift is proportional to the distance of the object, allowing astronomers to estimate the speed at which galaxies are moving away from us.
What did Edwin hubble discover about objects in the universe?
That they are all moving away from each other at a great rate of speed and that speed seems to be acceleration.
What things are beyond the universe?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
Is space expanding faster than the speed of light?
Yes. The farthest parts of the observable Universe are getting away from us, faster than the speed of light. The Wikipedia article on "metric expansion of space" can give you more information.
What are the universal things?
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?

This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
What theory explains why the universe is expanding at a great speed?
The cosmological theory holding that the universe is expanding, based on the interpretation of the color shift in the spectra of all the galaxies as being the result of the Doppler effect and indicating that all galaxies are moving away from one another.The cosmogonical theory holding that a violent eruption from a singularity led to the formation of elementary particles, the subsequent formation of hydrogen and helium, and the dispersion of the galaxies from these elementsSkaterboy15
What does rapidly expanding mean?
increasing in mass at a great speed
How is the space growing faster than its keyword?
The universe is expanding at a faster rate than the speed of light.
What would happen if the galaxies in the universe start expanding faster than the speed of light?
we would be all screwed
How universe is expanding at a rate faster than speed of light?
It is not. Nothing that we are aware of moves faster than light.
Is the universe expanding faster than a Boeing 747 can fly?
In fact, distant parts of the Universe are moving away from us faster than the speed of light.
Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
How is it possible that the expansion of the universe is faster than the speed of light?
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
