I forgot to mention this but the next event that would cause an event which involved more then one cinematic universe would be Guardians of the Galaxy.
After the events of Guardians of the galaxy, Ronan is defeated and the existence of an infinity stone is made public to the universe and us; the audience. It is undoubted that the infinity stones wield a great deal of power. So much so, in that, they surpass all beings in their universe. This sets in a chain of events which will lead to the Mad Titan, Thanos, to pursue the stones. But, what if after the stones were revealed, they sent a powerful signal throughout the omniverse. What if that was how Thanos managed to find the stones? What if Thanos wasn’t the only being alerted by the infinity stones after they were made public? My theory is that after the power stone was revealed, all surrounding cinematic universes felt the temporal shift in the omniverse. This would happen with infinity stones that would later be revealed in upcoming movies. For now, let’s call an event that involves 2 or more cinematic universes as an omniversal event.
This temporal shift would set off the events of Godzilla 2014, and Jurassic world in 2015. (notice they are all in other cinematic universes)
