Question: Expansion of the universe

[IMLearningEng]

Hello, I started this account to ask you about that, if the place of big bang was in the middle and we are on its right side, we can't observe that what was on the left side?
My train of thought: << (Left side, object) <<<(Big Bang)>>> (Right side, we) >>

There was no "middle" to the big bang, no center, no left side, no right side.

Phind's Excellent Balloon analogy will fill in a lot of gaps, for further reading I ercommend the following, and yes the links are under my signature as well. This question is so common its handy to have on hand.

You will find various literature to study and get started in Cosmology under my signature at,

particular articles of interest are,

http://cosmology101.wikidot.com/redshift-and-expansion, (note I have a few minor metric corrections to make on this one, but overall still accurate)
http://cosmology101.wikidot.com/universe-geometry

some excellent articles with visual graphs etc. Will definitely clear up some misconceptions.

http://www.mso.anu.edu.au/~charley/papers/LineweaverDavisSciAm.pdf: "Misconceptions about the Big bang" also Lineweaver and Davies

if your interested this is a very basic article on relativity its more a historical reference article.

As far as historical references I've compiled numerous articles. Including

Reprint of one of Hubbles papers

The "Great debate of the 20's" jubilee reprint article avalable

The historical articles will help show how much as changed in the last century. Feel free to ask any questions and enjoy

Hello, thank you for your question. The concept of the expansion of the universe can be difficult to grasp, but I will do my best to explain it. First, the Big Bang did not occur in a specific location, but rather it happened everywhere at once. It is the moment when the universe began to expand from a single point.

As the universe expanded, it carried matter and energy with it. This means that objects that were once close together are now moving further apart. So, in a sense, we are all on the "left side" of the Big Bang because we are all moving away from it.

However, it is important to note that the universe is expanding in all directions, not just left and right. This means that even if we were on the opposite side of the Big Bang, we would still observe the same expansion.

Additionally, the expansion of the universe is happening at a rate faster than the speed of light, which means that we are unable to observe objects that are too far away. This is known as the observable universe.

In summary, the expansion of the universe is a complex concept, but it is not limited to one specific direction. We are all a part of the expanding universe, and our observations are limited by the speed of light and the distance of objects. I hope this helps clarify the concept for you.
