Ok sir I have understood it as there are no evidence till yet in support of the flat 3 torus and we have to make more assumptions in order to consider this shape. Data is consistent for the one which requires minimum assumptions. So do we know the shape of the universe yet , if we do then of...

As stated in the introduction, investigations within the study of the global structure of the universe include: •Whether the universe is infinite or finite in extent Whether the geometry of the global universe is flat, positively curved, or negatively curved Whether the topology is simply...

Sir I'm not making a claim but just asking that could it be possible. As I have read it in some articles. Here I will post the lines from the article of Wikipedia which makes me think this way. If we assume a finite universe then possible considerations Assuming a finite universe, the universe...

Yes Sir https://en.m.wikipedia.org/wiki/Shape_of_the_universe Here I will tell you the headings in which you can look into this matter more quickly. •Shape of the observable universe. •Global universe structure

The surface of the torus is termed as flat and surface is a slice of 3d as it is 2d. The point on which I want to drag your attention is that the universe can be in the form of torus and as there are no ends to it , it can be termed as endless universe. But being endless doesn't mean it is...

I thought we do not know whether the Universe is finite or not. To give you an example, imagine the geometry of the Universe in two dimensions as a plane. It is flat, and a plane is normally infinite. But you can take a sheet of paper like an 'infinite' sheet of paper and you can roll it up and...

Sir on what reference we are saying that it is homogeneous. In order to understand FLRW Model. It is important to grasp why it is considered homogeneous?

How spatial distribution is homogeneous in our actual/ observable universe.

Ok Sir. I'm not here to debate anyone. Can you tell me more about spatial distribution of matter as my purpose was to get a clear picture of this.

Your statement is incorrect. Isotropy is about exhibiting same properties in every direction while homogeneity is about uniform composition. Here are two examples 1. An example of something that is homogeneous but not isotropic is a space that is filled with a uniform electric or magnetic field...

Okay the universe is same in every direction is an indication of it's isotropic behaviour. What about it's homogeneity?

However if the observable universe is expanding which the results shows it is then it's volume must be increasing or the space in the universe is getting increasing. For analogy we can say that if we put gas into a balloon it's volume get increased and as it volume increases it displaces the air...

Can you throw more light on homogeneous spatial distribution and how would our universe look if it was heterogeneous..?

The space - time is always curved is hard to digest. Because the % occupied by matter and energy I'd only 5% of the total cosmos. The respective is dark matter and energy . Can we say that flat or unmanipulated space- time anddark matter and energy are same? Here is the link of the blog...

I'm asking about that space- time which is not curved. i.e what is the nature of that space-time which is not curved.
