So ultimately this means if we shrink it down billionths of a proton in size there has to be surrounding matter which gives proof of something outside the observable universe.
Yes you are right, this is connected to the other topic (with the red sphere).

There also has to be something that sparked the exponential growth?
There is a solution of general relativity which describes a negative pressure material which produces more repulsive gravity than it's mass creates attractive gravity---resulting in a net repulsion--- . This theoretical particle (never been detected of course) is called the inflaton (a play on the word inflation).
The hand-waving goes something like this:
- Universe in unknown state, but small enough to be thermalized.
- Creation of a virtual inflaton
- Rapid expansion begins which is a run away process while the inflatons are present
- decay of inflatons into normal matter that we see today
- rapid expansion comes to a halt
It's a nice fairy tale story that has been cooked up to explain how you can get a universe that looks more or less like what we see today from essentially nothing, without violating any laws of physics (quite an accomplishment, even for just a story). The shocker is that the pretty good evidence for the bolded part was just found.... making it a bit more than a fairy tale (there has been lots of other less direct evidence for inflation that has been known for years of course).
