Check out this screencap from
Cold Front:
Notice all these curved lines, hundreds of them. Doesn't it appear that each represents a different timeline?
Mach 5:
Good one. It definitely looks like that scene is showing multiple time lines.
(Here is a video clip of the scene for anyone who's interested...)

And to quote Daniels once more:
You think of time travel as if it were some H.G. Wells novel. It is much more complicated than that. You couldn't possibly understand.
Interesting. Yeah, I am gonna have to watch Shockwave Part 2 again.
However, I did make another interesting discovery, though. Changes within the time line can be reseted, repaired, or erased. Daniels says the time line is resetting itself in Storm Front Part 2 as if the events never happened. Also, in Cold Front, he is concerned about protecting that particular time line's history. Suggesting that time is one fixed time line.

So one could interpret that all the different lines in Cold Front is simply a road map of all the different temporal incursions that have broken up the one string (or one time line) into many different little strings (or mini changes at different points within the time line).
In other words: if someone were to believe in the fixed time line, they would have to believe that all time travel incidents on Trek (that should have had some type of effect on the one time line) were corrected by either some higher power being like the Q or Daniel's future protective time agency.
However, this does not mean: that the multiple time lines theory is completely out of the water, though. It is possible that Daniels meant that the resetting or changes of that particular time line (as if certain events never happened) could simply mean that they no longer exist within the time line that Archer knows about. Daniels is simply showing us that the changes within Archer's time line are disappearing from their view and continuing on another time line as if Vosk succeeded.
It is just that the version of Vosk (within the time line we seen) failed miserably and died.
So, let me get this straight, people: Aren't you basically saying everything succeeding TOS' Tomorrow is Yesterday happens in an altered Tomorrow is Yesterday Timeline? And everything after The City on the Edge of Forever happens in an altered Tomorrow is Yesterday/The City on the Edge of Forever Timeline. And everything after ... well, you get the drift.
NCC-1701:
To assume that that there are no changes in time when someone meddles in the time line is pretty odd. It is the basic cause and effect theory.
I don't think that's how time travel is supposed to work in Star Trek. This whole "Enterprise is an altered First Contact timeline" stuff really sounds like nonsense to me.
In ENT's "Regeneration", we see Archer mention to T'Pol about cybernetic creatures and Humans from the future. Which basically is the events of First Contact. Which puts the events we see on Enterprise within the wake of the First Contact Time Line.
Here is the quote from Memory Alpha...
Later, in his ready room, T'Pol comes to tell him she has contacted Tarkalea and informed them of their rescue of their people. Archer shows her what he was reading before. It is a speech that was given 89 years prior by Human history's inventor of warp drive, Dr. Zefram Cochrane. In it he had spoken about the events surrounding his first warp flight. He had spoken of a group of cybernetic creatures from the future who had intended to "enslave the Human race". They had tried to prevent the flight, but were stopped by a group of Humans, also from the future.
Also, it just seems very strange that there would not be any changes in the time line with Picard and crew's talk of the future and showing of advanced technology to Cochrane and Lily, too. I mean, sure it is not concrete proof. Daniels Future Time Agency could have corrected the time line for all we know. But the advancements in technology in the 22nd Century (shown on Enterprise) compared to our view of what the 22nd Century is in the other series (TOS, TNG, DS9)... suggests otherwise.
In fact, check my post below for further details.
