Thank you Dragon. Anyway, here's why I think the Afterlife isnt really separated from the mortal universe:
1. The most common point is Goku and Beerus's shockwaves they created during their battle being able to reach both realms (well the kaioshin realm anyway). Now, from what I know, wouldnt Beerus and Goku's fighting somewhat prove that they are connected to the mortal universe? Afterall, the shockwaves released by their battle were even able to transverse into the kaioshin realm and if they were totally separate, then the shockwaves happening on a level such as the mortal universe would be impossible to go into separate space-times. Furthermore, if Goku and Beerus were able to make shockwaves at that magnitude, then I'd say its safe to assume that if Beerus were to ever go up against someone powerful like Champa, then they too would be able to make shockwaves, if not, stronger ones than the ones Goku produced in his fight with Beerus, by a large magnitude. Yet, the fight between Beerus and Champa (in both the anime and manga) are only stated by Whis/Vados to be able to destroy both U7 and U6. The threat of their fighting, which is logically far more dangerous than Beerus's fight with Goku, is never portrayed as being able to reach different space-times such as the Kaioshin realm. In addition to this, If their shockwaves were able to transverse space-time, then why has something like the ROSAT room, a pocket dimension that is also a separate space-time, never hinted to be destroyed as well? It shouldnt make any sense that a realm near the size of a whole universe can be threatend by Goku and Beerus's clash from an entire plane away but not a realm thats planet sized at best and far closer to the range of their battling. And incase anyone brings up the Gotenks and Buu scenerio's, they only created a portal which connected the ROSAT to U7 so they could pass through as they please. So their attacks didnt really cross space-time, otherwise everyone at the lookout would have felt their fighting. Plus its as Sid said. We rate the fight between Goku and Beerus, including the shockwaves, as 3-A and have not accepted them to be Low 2-C. Unless an upgrade is in order, wouldnt 3-A shockwaves going into another plane just further suggest that the plane is connected to the mortal universe since 3-A power can affect it?
2. IIRC, Goku been consistently shown to be able to sense the KI signatures of beings like Supreme Kai and King Kai even from the mortal universe. That should be completely impossible if the Kaioshin Realm/Otherworld were separate space-times. And before anyone says "Goku's energy sensing can go beyond space-time", this shouldnt be correct really. After all, he wasnt able to sense Gotenks and Buu fighting in the ROSAT, another separate space-time. In addition, I seem to remember Goku once having trouble sensing the New Planet Namek when trying to find Dende because it was too far for him to sense their Ki. New Namek, a planet thats in the same dimensional realm as Goku himself. He needed to go all the way to King Kai's in order to get a better range of KI sensing to find it (plus King Kai pointing him in the right direction). So if Goku couldnt even sense one far away planet in the same universe as himself, I highly doubt he should be able to sense beings from an entire space-time away.... And incase anyone brings up a point such as King Kai being able to sense them from his home, remember King Kai is a Kai and an observer of the universe. Same thing with the other kais, normal or supreme. It makes perfect sense that deities such as them can sense beyond space-time, especially if its in a realm that they themselves watch over and preserve. For example, Supreme Kai told everyone that unlike Goku who needs to sense Ki, his teleportation wasnt limited he could go anywhere he wanted in U7. All because of him being a Kai. And we see proof to this when they used him to get to Namek and use Porunga to help Goku beat Buu. Basically, you could say Goku shouldnt be sensing them, but they can be sensing him.
3. Now, please correct me if im mistaken, but I remember when Goku took Cell to King Kai's world to blow himself up there and not on earth, the explosion was even seeable from the mortal universe (i'll try and find the vid that shows this if you want). Now that should also be completely impossible if they were separate space-times as not only would we not be able to see it, we wouldnt even be able to sense it either. And considering Cell at that time was, what 4-B? His power should have been no where near great enough to be able to penerate realms. We have never seen something like this until Super Shenrons light was bright up to light up 2 universes.
Here are my points. Are they okay or are they too flawed?
