Reply to comment by ProTechYoNeck in Is the Milky Way... Normal? by cciccitrixx

No, you’re misunderstanding my analogy. In the balloon example, the surface of the balloon is the universe. The center of expansion is nowhere in the universe in that analogy. Another way to say it would be: can you point to the location in the universe which is the center of expansion? Can you go there (if you could teleport)? The answer to both questions is no.

Also I’m not sure what you were saying about an infinite universe so perhaps we agree, but there certainly is not a center to an expanding infinite plane.

Ok so saying this balloon is a perfect circle with no nipple, the surface of the balloon would be the universe and the space on either side of that surface would be nothing right?

Yup, exactly. The idea of the space on either side being “nothing” is extremely hard to fathom for me honestly, but it’s the only way to interpret an expanding finite universe (that I know of).

I mean unless the distance between the opposite sides of the surface is a number between 1 to 0 which can be infinite.

I get what you are saying. I'm still skeptical of the current idea being presented here. There are still anomalies that are seen in the cosmic microwave background that stands either for or against the current model but, it's still up for debate.

I appreciate your willingness to discuss the topic in a civil manner. Only thing I'll leave you with is to continue to question the way the data is being interpreted. It might lead you somewhere you might not have thought about
