Deceptively simple ending...

I think most people have jumped to the wrong conclusion about the ending. Those people who are thinking about "an endless time loop" are missing the simple answer.

First...I propose that what is placed in the ISS within the locker is *NOT* Andromeda but rather the bacteria from hell (from the bottom of the ocean near the volcanic vents actually...forgot the name of it). Here is why I think this:

1) The future actually gave the present this instruction. The future provided name of the bacteria to capture, the locker number to put the captured bacteria in and a symbol to place on the vial containing the sample so that there can be no confusion as to it's content.

2) The future is attacked by Andromeda (don't know its origins...probably alien) but the future is able to figure out its composition and from historical data, realizes that the bacteria from hell is the only way to kill it.

3) There is no bacteria from hell in the future because of man's ocean floor mining...the future is doomed unless they can get there hands on the bacteria from hell.

4) The future creates a worm hole and sends Andromeda back to the exact location in space and the exact time that it will hit the Scoop satellite (they have records in the future) AND before ocean mining wipes out the bacteria from hell.

5) The future knowingly and willfully creates the condition that Andromeda will be loosed upon the present. Why? Because Andromeda has to be taken seriously and though it will kill people in the present, they are willing to take that chance given that the bacteria from hell still exists in the present and that with the proper messages, the present will be able to kill Andromeda with the bactera (as it did in the movie).

6) Now, it is not enough to simply say "Don't mine the ocean floors" and let it be because 500 years from now, mankind may have forgotten that message and for all we know, the "future" may be thousands of years ahead of us. The future can't rely on the goodness of man to not mine the ocean floor anymore (indeed, the president seemed intent on still mining)...they need to put the bacteria from hell in a safe place *NOW* that can be retrieved in the future. So...they told us were to put it and how to mark it so that in the future, they have a sample of the bacteria from hell that they can use to combat Andromeda.

6) And finally, the last sample of Andromeda that wasn't wiped out (because the good doctor was trying to save her family) escaped from it's container in Wildfire and it wasn't even the human killing kind...it was a mutation that ate plastics (or whatever...but not humans). There were no samples of the human killing Andromeda left to put in the ISS!

7) It is true that the military wanted Andromeda samples but they didn't get them. Whoever killed the General and the Colonel and why is a mystery...I don't have that one figured out yet...
