Common sense just hit me! i was thinking Tobi has "
space time ninjutsu" meaning that he can "Warp" space time to travel to any Designated point he wants almost instantly! but in astrophysics/ astronomy a Black hole performs the very same thing tobi does! Sucks in it's surrounding into a single point at such a rapid rate that he is able to travel faster than the speed of light to any point is
space or
time which means Tobi can
TIME TRAVEL!
It all makes sense now why he said (middle-right panel)

He
IS Madara! but lets say that he tried to Complete his Moon's eye plan b4 in the past and failed then he Time traveled back into the past, it's a good theory in my view! that would also explain how he knows so much about the Sage of six paths and the History of the ninja world! Good theory but it dosent explain how ET madara died/knows
him. but i think it's a

tought
it kinda makes sense, Just think about how much Experience and knowlede u'd have to have to be able to Become the 10 tails Jinchuukiri? or to learn the " Mugen Tsukyomi" i doubt ET Madara was able to achieve such things during his lifetime, despite being the strongest ninja of present times.
Naruto Movie 4 Proves that Space-time Jutsu allows the user to travel through time, but under a certain criteria. thats what happened to Makude.
Movie or not, it's still the "Naruto world" the Movies wouldn't include things that are impossible in the naruto world, like Naruto meeting Luffy. but it's still the "Naruto Universe" Anything depicted in Naruto movies are possible in the Manga and anime.
