How is Madara still alive? What if...Madara+Obito=Tobi

[Will of Fire]

Its seems Madara is immortal... the question is HOW?

I was reading the threats about Madara-Tobi-Obito and ended up on the threat of Raph95 ''Another thing which is hinting Obito=Tobi''...then i came up with a theory...

Taking into consideration that Madara is Tobi, since Tobi said it himself that he iis Madara...http://img269.imageshack.us/img269/812/tobimadara.jpg

I thought that Madara used the Transfer Jutsu ,like Orochimaru[he might even took it from him while he was still in akatsuki] and transfered into Obitos Body...
We didn't see Obito deing, so Madara could have just found him unter the rock and thought ''hell I'm lucky..an Uchica''
So in case Obito's right eye was not crused [...if this is not true http://img37.imageshack.us/img37/16/obitoedited.jpg ] this theory might really be true...

I addition if we add Raph94's theory [http://www.konoha-village.com/showthread.php?t=3531]
...that Obito had mastered this Sharingan Jutsu [the time/space traveling]and his left eye was taken by Kakashi and his right+the holl uchica body by madara/tobi makes even more sense...clever theory btw

But there is more... the fact that for was some reason we haven't still saw Tobi's [=Madara] face and we have only seen him using his right sharingan eye [Obito was left with only a right sharingan eye] because of the mask...makes me believe that theory even more

One last clue is that tobi who is madara [ok, i'm reapiting myself] seems to have hair that look a lot like Obito's
...and he hasn't he old long hair
