The size is not relevant to the point, geographical locations have no reason to be inaccurate, as in, if Earth is pointed to be in a particular place in the globe, there is no argument as to why that would be inaccurate or false.
This size counterargument is meaningless.
You might take that as an indication of how far they are. but again, how do you measure were Yardrat is? We don't know how much time it took Goku to reach Yardrat, he used a spacecraft that can cross approximately the entire universe in a year and traveled anytime in the span of 130 days (that's the time they summoned Porunga).
It literally means they are outside of their galaxy lol, and then going across the universe starts to make more sense here, especially when stated by the site also. The whole point is protecting peace in the galaxy. That is the GP range.
The Galactic Patrol clearly doesn't operate within the boundaries of the same galaxy. Jaco was sent to check on earth, but was seen going somewhere after Cereal and the prison was even farther, close to the dinosaur planet allegedly so far from Cereal.
Besides, the notion of jurisdiction is bound by law, not distance. Yardrat might be outside the federation, just like the planets under the Frieza force. Even in the real world works this way.
The fact Goku's SSJ3 Ki was felt on the Kai's planet was shocking to them. How would Ki from mere Namekians cross a dimensional barrier?
I don't see how the things are relevant to each other.
You can sense ki across dimensions, but it takes a real strong ki to physically affect it, and that's a matter of AP.
You might disagree with me but this point is silly. You know there are universal rules set by the Gods of the verse who wouldn't let this happen. Even doing something as trivial as visiting the living world for a day is costly.
That's honestly speculation on your side.
Also, did you not see when I mentioned there is a magical seal that keeps the Afterlife not accessible to mortals?
Show me any actual proof of these spaces being connected, instead of speculation based on teleportation and travels performed by characters who can casually cross different realms.
And while we are at it, you can take a knack at the Dragon Ball tiering that is based on this separation.
