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.
An open universe is one that?
An open universe is a universe where all of the galaxies and stars and everything in the universe keep expanding with nothing stopping them. This theory says that the galaxies and stars will keep going further and further from the centre of the universe until everything dies off. This is the opposite of the closed universe theory where everything will expand, and then something will cause a turning point and everything will contract until everything there ever was will fit into a space the size of the dot at the end of this sentence. Then, possibly another 'Big Bang' will happen and start everything over again. :)
How did the universe started?
Science has advanced to the point where we can infer something about the entire universe. This has been a great challenge considering how unimaginably vast the universe is. The countless stars you see in the darkest sky constitute merely 3000 neighbors out of about 300,000,000,000 stars in our galaxy, and as many as 100,000,000,000 galaxies exist in the universe. Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the beginning of this past century, we found out in amazement that the entire universe is expanding. This led physicists to deduce that the universe started out in the finite past with a minuscule size. Realizing that the universe had a beginning, and awed by its vastness and its creations, people have asked: How did the universe begin? After all, we are here to be amazed by it because the universe eventually created lives like us. Now, after decades of observing and thinking, we have come to answer confidently the question of the origin of our universe... with what is known as the "big bang".
What is the process used by astronomer to estimate the number of galaxies in the universe?
They used a method called "representative sampling" to obtain their estimate. The sky is divided into sections of equal size and the number of galaxies in one section are counted. The count from that one section is then multiplied by the total number of sections in the sky
Does red shift expand the universe?
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then (size of universe at redshift z)/(current size of universe)= 1/(z+1)

Are all 100000000000 galaxies in our universe be any size and shape?
Yes, galaxies can be any size and shape.
How the size of the universe changed not the size or mass of the earth JUST the universe?
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
What did the existence of galaxies reveal about the size of the universe?

If the universe is infinite then why are there a finite amount of galaxies?
It is not yet certain what size the Universe is, not even approximately - but it is probably not infinite. If you have seen an estimate about the number of galaxies in the Universe, it probably referred to the OBSERVABLE Universe, which is definitely not infinite.
How many galaxies found in the universe?
The observable Universe has somewhere around 1011 galaxies. The entire Universe is much larger than the observable Universe, but currently, it is not known exactly how much larger. It might be infinite in size, but in any case, it is estimated that the Universe is a lot larger than the observable Universe.
Is the milky way galaxy growing with the universe too?
No, the growth of the universe is caused by the galaxies moving away from each other, with no relation to their size.
What happened to universe right after big bang?
It began to expand in size. There is a hole at that point in our knowledge of the early universe but without a doubt the universe began to expand.
Will humans ever explore the entire universe?
It is unlikely that humans will ever be able to explore the entire universe due to its vast size and current limitations in technology. Even with advancements in space travel, reaching far-off galaxies would take an immense amount of time and resources. However, through efforts like space telescopes and probes, we can continue to expand our knowledge of the universe.
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.
How can astronomers make a mosaic of 100 billion galaxies in the universe of every shape size and color?
Astronomers could make this complex mosaic on the side of a large building, but it is unlikely that they would be able to include all 100 billion galaxies (i.e. 60 billion spiral/barred spiral galaxies, 20 billion lenticular galaxies, 15 billion elliptical galaxies, and 5 billion irregular/peculiar galaxies).
