No, it's well explained but the problem lies on thinking that space is only the surface of the balloon but it isn't.
The problem with the balloon analogy that it can't show you how other objects expand inside the balloon similar to the surface of the balloon and to do that we have to make a multi surfaces balloon, such as having one larger balloon and smaller ones in the larger one and inflating them all together, this view is even better explained by the raisin bread analogy in which you can see raisins at surface and inside and in all directions of the bread to explain how the space do expand.
You do know what an analogy is, don't you?
An analogy is only a representation of what it is attempting to describe - the phenomena or some specific characteristics of that phenomena. It is comparison between the real thing and the representation that have some similarities.
Analogy is never meant to be exact. The balloon analogy is of course not 100% accurate. (Actually no analogy is 100% accurate; that's why it is analogy, a mere representation.)
The analogy have specific purpose and specific meaning, as do the balloon analogy.
The balloon analogy is only meant to be example of describing the expanding universe, and representation of what it mean by when they are referring to the "centre" of the universe. It is not an exact representation. If it was the exact representation then you wouldn't need the theory of the Big Bang.
So of course, the balloon analogy wouldn't describe everything about the Big Bang.
Instead of reading and knowing what the analogy mean, and what the analogy is supposed to represent, according to your previous replies to me, you have deliberately misrepresented the analogy, by changing what it mean or by what you wish it to mean.
You was the one who brought up the balloon analogy in the first place, not me. You were the who quiz me if I knew anything about the ballon analogy:
I assume you know the balloon analogy for explaining how the universe expanded, scientists think that the space existed before the inflation...
In short, I know what the analogy is saying, what it mean without changing its context.
But in the next part of your sentence, you have continued with this:
...similar to the space inside the balloon which existed before expanding, they called it the false vacuum and some scientists believe that we're still living in the false vacuum.
You are trying to focus the analogy away from what Arthur Eddington's analogy, to what you deem to be important, the air inside the balloon.
The air inside the balloon is never important part of the analogy, but you either don't understand the analogy or you know what it mean, but decided to change it.
The balloon analogy never really talk of the inside the balloon, or the air, which you have called it the "vacuum" or "false vacuum". Apart from the air inside causing the balloon to physically expand in size, the air is totally irrelevant.
The universe in its entirety is supposed to be represented by the balloon itself. All the stars and galaxies are represented by any dot or any object you have drawn on the balloon. The "space" is any parts of the balloon that haven't been marked by your pen; so that space on the balloon (unmarked).
The point of the analogy is too show that everything in the universe is expanding, but it has no "centre". There is no centre on the surface of the balloon because everything (space and matters) in the universe is expanding with the universe, by moving away from each other.
Try understanding the analogy, not change the analogy's context.
