Naruto, kakashi, kyuubi, gai-sensei just found out how to pass by Madara's space time jutsu where he teleports him / other objects to a different dimension. However after finding it out, they were able to crack madara's mask and it seems that uchiha obito is madara after all. I wouldn't believe it as it was just fan-made made up shit thought by watchers, but it's actually the truth :O
