Which is just another way of saying "a wizard did it." Unless there's a canon reference dis-establishing matter-energy equivalence--which DIRECTLY establishes this equivalence can only be realized by annihilation--then the point stands.
If you wish to resort to draconian descriptions of 'a wizard did it', then go right ahead.
Keeping in mind the fact that we are in technological infancy today and SF operates on an entirely different angle (which also breaks numerous things we established to this day), making a preposterous claim that YOU know better and what we will be capable of doing in 200 years ... well, that's just downright arrogant and not really worth contemplating.
So stop begging the question: IS there another way of converting matter into energy, or do you just assume there is a way because you think you saw something on Voyager that kinda seems like there is?
Actually, I interpret on-screen evidence as a given with what was previously established and I don't draw things from a non-canonical book.
Other than the thousands of factors I've already mentioned, plus the fact that in DS9 "Babel" it is explicitly shown that Cardassian replicators use a raw material feed into the machinery itself to be reorganized instead of piping it from a holding tank via waveguides as in Starfleet replicators.
And by 'factors', you mean, drawing from our own limited scientific knowledge of the early 21st century when compared to the late 24th century science and knowledge?
That's laughable.
As for Cardassian replicators ... we saw on numerous occasions liquids and various forms of raw matter getting into several ship systems when they were damaged (and the malfunctions affected the entire station in that episode). Also point remains that those are Cardassian issue replicators built on a mining station decades before SF set foot on it.
Cardassian tech was repeatedly stated to be inferior to SF's.
And as I've already explained, it isn't energy intensive the way matter-energy conversions are energy intensive. You might as well be suggesting that fuel cell cars are powered by fusion reactors just because they use hydrogen as fuel.
I'm hardly suggesting anything ... you are the one focusing on comparisons between warp cores and cars ... when one is nothing alike the other.
What about it? We don't know what it's made of, whether it's a physical structure or a highly sophisticated holographic material. If it's the latter, then it does the same job as conventional deflector shields only with half the energy and twice the effect.
Oh I definitely concede the possibility that it's a highly sophisticated holographic technology, and yet, when we see the armor opening for the torpedoes, it's not a simple fading de-materializing effect, it's also physically opening.
It behaves nothing like holograms for one thing, and I would imagine it would have to be physical structure (and the effect it had in protecting the ship from Borg weapons was far higher than mere 'twice as much').
You wouldn't. Unfortunately, what you're forgetting is that, if you can't store that much matter, then BY DEFINITION, you cannot store that much energy either. You can always store more matter than you can store energy. In fact, you can store ALOT more matter than you can store energy, several orders of magnitude in fact.
Again drawing conclusions based on contemporary understanding of it.
How do you know SF hasn't discovered a way to store equal amounts of energy and matter ... or storing/producing much MORE energy than matter (which would make sense if they are converting it into matter).
So the Endgame Batman Armor would have to be something requiring relatively small amounts of energy or else it would be a wasted effort (and even Janeway's little shuttlecraft is capable of using it, so this is a given). We at least know that holograms are sufficiently energy-cheap that they can be generated and sustained even with main power disabled, so a highly coherent solid hologram (essentially, a forcefield shaped into a solid plate) would fit the bill nicely.
Not necessarily ... Voyager never engaged the Warp engines to begin with, and Admiral Janeway came from 26 years into the future, where technological discoveries could have been enormous by comparison (since it's a timeline in which Voyager came back from the DQ filled with all kinds of techs, and not to mention the various knowledge SF acquired in the earlier years from more powerful races that would be deciphered in a more meaningful capacity around that alternate future era).
Thereby producing more energy than five hundred warp cores literally out of nowhere. Which, again, is another way of saying "A wizard did it."
Of course, since 90% of what happens on Voyager fits that general definition, this isn't surprising.
Your chosen interpretation of the show, which I respect, but of course do not acknowledge.
I also thought that DS9 was sub-par compared to other Trek shows (but that's just personal taste).
Using anything resembling real science, it would threaten them very much in the SHORT term too.
'Real science' (or rather what it established) was revised as time went on.
Some rules were outright broken, others were bent.
To NOT keep in mind this kind of aspect on a far larger scale (especially when talking about the Feds and all of the factors involved) is just plain small-minded.
I keep an open mind to the possibility that replicators are merely re-arranging raw matter into new materials, but given everything that was shown on-screen to be done by SF ships to begin with ... to discard direct energy to matter transformation would be short sighted.
