There are several pieces of evidence. One important piece of evidence is the redshift of distant galaxies. That is, the change in the color of the light that reaches us indicates that far-away galaxies are receding (going away) from us.
Answer2.
The redshift itself is misunderstood and is weak evidence for an expanding universe. Hubble is the authority on the redshift data and Hubble does not support the redshift interpretation of an expanding universe. The universe is not expanding it is in scalar equilibrium and the redshift is evidence of this equilibrium. At the speed of light the universe is also in vector equilibrium, F= ma= 0.

Hubble believed that his count data gave a more reasonable result concerning spatial curvature if the redshift correction was made assuming no recession. To the very end of his writings he maintained this position, favouring (or at the very least keeping open) the model where no true expansionexists, and therefore that the redshift "represents a hitherto unrecognized principle of nature". This viewpoint is emphasized (a) in The Realm of the Nebulae, (b)in his reply (Hubble 1937a) to the criticisms of the 1936 papers by Eddington and by McVittie, and (c)in his 1937 Rhodes Lectures published as The Observational Approach to Cosmology(Hubble 1937b). It also persists in his last published scientific paper which is an account of his Darwin Lecture (Hubble 1953).
What else can I help you with?
Do scientists think that the universe is expanding?
Yes
Is the universe infinate?
Scientists currently believe that no, the universe is not infinite. It is of a finite size however, this finite size is constantly expanding but not expanding AWAY from anything, just expanding
Is the universe imploding?
There is no evidence of that, in fact most scientists believe it is expanding.
Scientists determined this was expanding by using the spectrograph?
Scientists determined that the object was expanding by analyzing its light spectrum using a spectrograph. By observing the Doppler shift in the spectral lines, scientists could infer the motion of the object relative to Earth, leading to the conclusion that it was moving away and expanding.
If scientists say the universe is everything and the universe is always expanding then what is the universe expanding into?
It is not exactly expanding into anything. The galaxies are moving apart from each other, from which we can infer that the universe is expanding. Theoretically, this is a result of the Big Bang, in which the universe began when all matter was compacted into a very tiny sum, and then exploded apart in a very big bang, and as a result is still expanding today.
How big do scientists predict the universe will become?
It seems it will continue expanding forever.
What is the universe expanding in to?
It is not exactly expanding into anything. We don't really know.
How big is the universe you know?
The universe isn't a place that has stayed big for years. The universe keeps on expending. Scientists don't when this expantion is going to stop but they do know that planets are constantly being created while expanding. Who knows, God might be doing this
How do we know the universe is expanding?
well we don't
How many Earths can fit into the known universe?
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
Is the universe infinitely expanding or does it expand to a particular limit?
This question has been giving nightmares to cosmologists for years.But with the current evidences, scientists have determined that the universe is expanding at an ever-increasing rate and it will expand forever.
Does the universe keep on expanding?
Yes, and so far, scientists have not yet accounted for enough mass in the universe for the expansion to ever come to a halt and start the universe contracting.
