Maybe Madara is the great grandfather of Obito.
Being direct descendant from Madara, Obito could have some special jutsu (Kamui). Madara could had teach him.
Direct descendant could have almost the same DNA and others special skill.
There is something still puzzle. Why Obito wear goggle ??
Example: Sasuke had reach the higher advanced skill level in MS, just like his brother, Itachi. Also Itachi had given certain power when Itachi using 2 fingers touched on Sasuke's eyes above, making Sasuke to see what Itachi past experience.
Not all Uchiha could had the MS skill.
