Lol, nice to see my assessment is at least accurate. As none of my other theories seemed to have panned out. Like the black or white hole theory, the time dilation for Tucker due to crossing the event horizon of a black hole, causing all the messages on his phone to come all at once and from time he hasn't experienced yet, or so he thinks. All the time, like all of it, in the universe he left would've passed in a literal instant, to the point his universe no longer existed because it came to the end of it's time
