Halo 3 Ending (Time Travel Theory)?

[Halo2178]

Does anybody believe that the planet at the end of Halo 3 is actually Reach? When the 2nd half was cutoff during the explosion?

Master chief gets seperated form that alien and lands on a planet thats y they are making halo reach when the ODST go and reach to master chief

The planet Chief landed on? Nothing supports that it could be Reach, and nothing even hints any possibility of time travel in the entire series so no, I don't believe any speculations as to what it is.
