How do observations of distant galaxies tell us that the universe started with a big bang?

The discovery and mapping of the Cosmic Microwave Background Radiation (CMBR) via WMAP mission has been interpreted as being left over from the Big Bang. It provides support for the hypothesis of a hot dense state at the beginning and also provided measurements to explain that galactic clusters are still moving away from each other at an ever increasing acceleration. WMAP's measurements played the key role in establishing the current Standard Model of Cosmology: the Lambda-CDM model. In the Lambda-CDM model of the observable universe, the age of the observable universe is 13.772 ± 0.059 billion years.

How old was the universe when young galaxies started to form?
about 1 billion years old
Are distant galaxies moving away slower or faster than nearby galaxies?
Here is what i belive to be the correct awnser. If you belive in the big bang theory then you swould know the universe started from the middle and started expanding out so the closest galaxie is moving away with us but distant galaxies are also moving away from us now i dont know about how they move or what speed they move at or if theres a differnce it is possible considering some galaxies formed billions of years after our a slowley catching up with as so i belive it varies now i hope this answer your question people may edit this in future and make it easyer to understand.
What theory explained that the universe started as a hot ball of materials which exploded and become stars and galaxies?
The " Big Bang "
How was the galaxies and stars and planets made?
Most people believe that all started with a big bang and all the pieces fall out and some of them form galaxies. Nowadays the Universe is still expanding
Why do galaxies expand primarily on one plane as oppposed to all planes ie a plate instead of a sphere?
Because galaxies don't expand. The universe expands. Think of galaxies as little spots on a balloon. When you blow it up the surface gets larger not the little spots, but the spots do get further apart. Gravity creates the extreme flatness that you observe. Moments after the big bang the initial structure of the universe was set, that applies to the size of the galaxies as well. The only observable difference is the galaxies were a lot closer to each other in the beginning. Gravity then took over and started effecting the closest galaxies by pulling them closer together. The galaxies face a battle between the expanding universe and the gravity of other galaxies.
What does science tell us about the origin of the unverse?
The galaxies in the universe are continuously moving away from each other.Hence it is presumed that at some point of time they were all close and that the universe started from a huge bang which resulted in the "point" size universe growing into the vastness of today.
There are how many galaxies?
Galaxy Theaters have locations across the west coast. Overall, there are 12 locations spanning over the states of California, Nevada, Texas, and Washington.
How did the universe change after the big bang?
The big bang started over 100000000000000 milion years ago.The earth started off colder then russia, but now its riseing temps is dramaticly causing global warming
Why galaxies are going far away and the universe seems to expanding?
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.

Did the Milky Way explode fourteen billion years ago?
No. The milky way did not exist at all, fourteen billion years ago. According to the Big Bang theory, the first galaxies started forming at least a million years after the universe had started to expand.
How formation of universe?
The material that is currently in the Universe started something like 13.8 billion years ago, very close together, very dense, and very hot. It started expanding (space itself expanded) in an event called the Big Bang. Eventually, the material became galaxies, stars, etc.
What drove cosmic inflation?
There are a number of reasons to suspect that the universe started from a point: 1) All the distant galaxies are headed away from us, so 13.7 billion years ago they were in one spot.. 2) The macro-universe is no different on opposite sides. Nothing has had the time to smooth out both sides. 3) The Microwave background noise is everywhere, and it is an echo of the "Big Bang" (sort of...). So how did the universe get from a tiny point to what we have now? Well the best theory is that in the first second of the Big Bang, SPACE (not matter) inflated tremendously fast. This is a complicated subject, but much is know about what happened, and many pieces of evidence point in this direction.
