In Response To: Re: A stupid theory (Shishka)
: To be more direct to your theory, Halo is designed to "stop" the

: be "stopped" by resetting time, in fact it'd cause repetition of
: the event.
Yes, but the first time around (before the Forerunners reset the Galaxy) the Halo's wouldn't have been there. What if the Forerunners came long after the Humans and Covenant died off? When they reset time the Halos would have still been there from the last firing, since they wouldn't be included in the reset. (The halo was pointed at the Galaxy, so I'm assuming that it is immune to anything it fires) This would mean that time has been changed, as the Covenant and the Humans would have never discovered the dormant flood the first time around. Thus, that would end any repetition that may arise.
: Further, if it were a device to reset time, why wasn't it used?
If it is a device to reset time, then it has been used. Spark said that the Halo had been fired before.
: Lastly, if it were a device to reset time, why did 343 Guilty Spark tell us
: that it's designed to destroy sentient life in the galaxy? That has
: nothing to do with time travel. We were told it's a destructive weapon, so
: your theory is rather baseless.
It would destroy all Sentient life in the Galaxy if Time was reset, though. Everything would be microbes and fish with feet if it sent the Galaxy 15 Billion years back. The Forerunner didn't want to destroy the Flood for whatever reason; so how exactly, if the beam on Halo fires off a Neutron type wave, would the Flood survive?
