No need for a generation ship if you can travel much faster than
Light.
Light.
Was the Fabrini rock-ship travelling FTL though? The engine was described as an old fashioned atomic type, emitting a trail of debris and hard radiation. It was due to reach its target of "Daran 5" in 396 days, but that could easily have been in the same solar system where the Enterprise encountered it in the episode.If the asteroid was travelling beyond the speed of light then maybe it was another Fabrini refugee ship? Only the Enterprise hadn't encountered the first one at this point in time yet so may have sent that other big rock away from it's intended course unlike the other Fabrina in ignorance! Just joshing, it was a big empty rock!!!

Maybe. Or some peculiar natural phenomenon. But whilst an asteroid travelling at .5 c would certainly be extraordinary, it certainly isn't impossible.An asteroid (i.e. a natural phenomenon) travelling at half the speed of light? That by itself would require an extensive explanation to justify - unless the rock was launched by unfriendly aliens?
I'm fine with that, but it only makes the idea that Warp 9 is only lightspeed less plausible.FWIW, I wouldn't put too much stock in the WF^3 formula - even at its best, it is far too slow for what we see in TOS.
I always took the time warp examples as a rather special case. The way I've generally thought of it is that warp drive can move you through spacetime extremely quickly (space and time being aspects of a single thing). Under normal circumstances it moves you through space rapidly, but when you throw gravity into the mix it moves you through space slowly because it's moving you through time rapidly.Except that we have explicitly seen both the Enterprise (in Tomorrow Is Yesterday) and a Bird of Prey (in ST4) fly at the sun at Warp 9 speeds and yet only slowly approach it. I could also toss in Elaan Of Troyius as an example of a warping Klingon battleship merely crawling along at speeds measured in KM/H. So, in the Trek universe it really does seem to be a thing that whatever other benefits the use of warp drive might bring (such as initiating a time warp) high speeds (compared to deep space) is not among them.
But it would require an extraordinary amount of energy, especially for something described as being the size of Earth's moon. Since I am no scientist, I did a little googling on this subjectMaybe.

https://www.quora.com/How-much-energy-needed-to-push-a-spacecraft-to-half-the-speed-of-lightWe’re going to assume that we will accelerate the spacecraft uniformly at 1 g until the speed as seen from the Earth is 0.5 c. You have to specify what fuel you will use, and the mass payload [spacecraft + rocket engine]. Here are some numbers:
The ideal rocket weighing 1000 tons and using matter-antimatter annihilation as fuel will require 732 tons of fuel, producing 6.6 x 10^22 joules.
If the fuel exhaust velocity is 0.1 c, with an engine efficiency of 0.5, the required fuel mass is 59 million tons; the total energy jumps to 2.7 x 10^25 joules.
Finally, for the case of the fuel exhaust velocity of 0.001 c and 100% engine efficiency, the fuel energy becomes 10^255 joules!
Actually that's a thousand times more than the age of the sun.But it would require an extraordinary amount of energy, especially for something described as being the size of Earth's moon.
...4,656,627,880,447 years (which coincidentally is also the age of the sun!)
Thirty years ago they always showed asteroids as brown jagged rocks where as today I've noticed they are rounded white stone shapes, mysteriously enough!

Well that was embarrassing. Can I play the English card and claim that I was talking about a British billion? Maybe?Actually that's a thousand times more than the age of the sun.
That's an incredibly specific set of circumstances, but I suppose in theory anything is possible. However, let's not forget that the asteroid deflector on the planet handled this supposedly freak occurrence with incredible ease. I know that the planet is said to be in an asteroid alley of sorts, but just how often do demi-lightspeed moon sized objects happen by in order for the Preservers to over-engineer the machine to this degree?But again - ultimately, this is not impossible.
Somebody (you?) mentioned earlier, one could assume that it was pushed. That may be so. Or if my hypothesis that Enterprise saw a collision outside the system that started all this off is true, then perhaps that collision was something special - perhaps not one rock hitting another, but a large black hole striking a planet or something. Falling into a black hole can cause up to 40% or so of the mass of a given body to turn into energy. You'd have to model it to really know, but it seems to me that such an encounter could easily liberate enough energy to winde up with a fragment that was going at the required speed.
So imagine something planet-sized encountering a rotating black hole in interstellar space, a light-month or so from the planet. The planet is ripped apart by the black hole, with most of it converted to energy in a colossal explosion of energy. A moon-szied chunk of the planet is thrown out at relativistic speeds.
The Enterprise sees the flash and comes to investigate. They see the fragment hurtling towards a planet and contact Starfleet to report.
Starfleet says "Investigate the planet. If it's inhabited, do what you can to divert the asteroid. If not, observe the impact."
Hence why Kirk and co were on the planet at the beginning, why they had to depart so quickly, why it was so hard to deflect the asteroid. It explains a lot. And it avoids warp drive being massively slow.
Sulu then counts down the Klingon cruiser approaching (at better than Warp 6) at increments of 10,000 kilometres every 3 or 4 seconds. His timing puts the Klingons at around 3,125 kilometres a second, barely more than 1% of lightspeedSULU: Phasers ready, sir.
SPOCK: Their speed is better than warp six, Captain.
KIRK: Mister Chekov, lay in a course to take us out of this star system. If they want to fight, Let's get some manoeuvering room.
CHEKOV: Course computed, sir.
SULU: Laid in, Captain.
KIRK: All right. Ahead warp factor two.
SCOTT [OC]: Captain, the matter-antimatter
KIRK: Belay that order. What is it, Scotty?
SCOTT: The anti-matter pods are rigged to blow up the moment we go into warp drive.
UHURA: Captain, message from the Klingon ship. They're ordering us to stand by for boarding or be destroyed.
SPOCK: They demand an immediate reply.
KIRK: They're trying to force a fight. Scotty, what's our energy status?
SCOTT: Ninety three percent of impulse power, sir.
SPOCK: We can still manoeuvre.
SCOTT: Manoeuvre? Aye. We can wallow like a garbage scow against a warp-driven starship.

This is around twice the amount of energy that our sun produces in 1 second, just to heft that measly 1,000 ton ship. The moon is 73,476,000,000,000,000,000 times more heavy! That is equivalent to the entire output of the sun for 4,656,627,880,447 years (which coincidentally is also the age of the sun!)
A possibility: The beam doesn't just push the target asteroid, but also encapsulates it within a subspace field, thus lowering the target's mass. O'Brien uses a similar field in the pilot episode of DS9 and the TNG Tech Manual talks about "subspace driver coils" which effectively do the same thing (thus sidestepping the pesky issue of how the ship can accelerate to 25% of lightspeed without carrying many times its own weight in fuel)This also brings up two questions: how powerful is that artifact and why does it's beam not knock the planet out of orbit?
If it's just a pusher beam, the base must be being pushed against, the base being on the planet, for it to push that much mass it would either burrow itself down into the planet or move the planet.
Yeh I'm getting desperate here. I can't see that any 'natural' object could travel as fast as the Enterprise at Warp 9 in 3 hours in only 3 months unless we've established you can't travel Warp within a star system.There would have to be a phenomenal amount of debris inside the system to justify such a route!
Worse than that - it's only TWO months!Yeh I'm getting desperate here. I can't see that any 'natural' object could travel as fast as the Enterprise at Warp 9 in 3 hours in only 3 months unless we've established you can't travel Warp within a star system.
This episode's use of time and distance is a head scratcher though, and has been for years
