To accelerate a projectile to 0.1c in 10 seconds, the railgun would have to be about 150,000 km long. By comparison, the average earth-moon distance is about 384,000 km.

A railgun that could do the job in 1 second would be "only" about 1500 km long, but of course it would require 10 times the reactor capacity.

2442.6 The first test:
The buzzer woke Admiral William Ross up in the middle of the night; he woke up quickly thanks to spending fifty years in the navy (or in training) but he was still rubbing the sleep out of his eyes when he tabbed the com control and selected non-visual.
“Admiral this is bridge, I’m sorry to wake you sir but our sensors have just detected three cloaked ships moving through the system, we can generate an intercept but we can’t get a clear reading on what those ships are yet.” The voice on the other end of the line was the cold baritone of Elijah Jones and it took Ross a moment to recognize the tone of excitement in the other man’s voice.
“Alright Elijah get Rukia up and tell her to meet me on the bridge in five minutes, meanwhile have CIC generate an intercept course and get us on our way.” William grinned as he allowed himself a second of cruel pleasure at the thought of waking Rukia and returning the favor for her little training exercise the previous day that had startled him out of bed at three in the morning.
“Sir which division commander should I com about providing escort?” The Captain’s asked in a conversational tone.
“I don’t think we’ll need escort to intercept three ships Captain, this ship is supposed to be its own battle group after all.” William’s grin grew as the pause on the other end drew out a few more seconds.
“Yes sir I’ll com Commodore Fujita right away.” Captain Jones cut the com and William dragged himself out of bed and staggered over to his locker to get a fresh uniform out; So three enemy ships under cloak, this should be a pretty easy intercept, let’s just hope those boys back at NavTech know what they were talking about when the designed this ship. he paused a moment to grimace in the mirror as he fastened his collar before he turned to leave his quarters and head for the bridge.

Six hours passed as the Holy Crusade tore through space at 200 gravities acceleration attempting to intercept the three enemy starships that had been detected at long range, finally the massive Icaran warship managed to get within sensor range with their opponents.
“Admiral we have a clear ID on all three enemy warships, CIC calls it one SD, one monitor and one super monitor in formation.” A com tech reported calmly before the main plot flashed for a moment as the three red diamonds representing unknown ships transformed into the fully detailed holographic representations of each of the ships in the enemy formation, two of which were clearly Andermani in design while the super monitor looked like a Sol Coalition design.
Rukia turned to Ross and opened her mouth to say something when suddenly a voice from the tactical section caused her and William to turn around instinctively.
“Enemy ships have changed course, they are reducing acceleration and are apparently turning to intercept us.” The young sensor tech blushed when he noticed an Admiral and Commodore looking at him as if he had a third eye.

“They probably don’t realize we’re Icarans, after all an object 60km across moving under its own power is probably a little shocking.” Elijah Jones said as he watched the three ships closing at around 150 gravities.
“Well if that’s true we can definitely use this.” William turned to face the main plot and saw the distance markers counting down, “Weaps, inform all gun crews to plot minimum distance firing solutions.”
“Minimum distance?” Rukia kept her voice low enough so that only William heard; he nodded slowly and turned to face her.
“If Elijah’s right and they don’t know who we are then we can’t afford to open up on those ships at maximum range, God only knows what kind of weapons they’re packing and they might just have enough power to damage us, note I said damage not destroy but either way we can’t risk it.” His voice was cold as he ran the numbers of enemy crew through his head and came up with about 31,000 people, fellow human beings who would probably never even know what hit them.
“Enemy closing the range, approaching optimum weapons range.” The voice from the tactical section pulled Ross from his thoughts and he grimly turned his attention back to the main holoplot, the enemy was still too far out for an eyeball visual but they wouldn’t be by time the Crusade fired.
“They’ve got us lit, scanners running.” Another voice chimed out from a different section of the tactical department.
“Admiral, we’re being hailed, an Admiral Daniel Smith is challenging.” A com tech said rather icily as she listened to the message “He sounds confused as hell sir, and is telling us to hold position.”

“Almost in range, Admiral, twenty more seconds.” Elijah spoke this time as he checked his display tie-ins. A glowing red sphere appeared around the Crusade, representing the planned firing envelope, and the three ships closing.
“Sir again Admiral Smith is trying to hail, this time we’re getting broad frequency bombardment and multiple languages thrown at us.” The com tech’s voice sounded tenser this time as she too began watching the main plot.
William could almost feel his bridge crew trying to will the enemy ships into the firing envelope faster and realized that he almost felt sorry for this Admiral Smith as he realized that the other man was trying to get in closer to get better scans of his the battlemoon; then all thought froze as the red sphere began flashing and the three ships crossed into it.
“All batteries open fire.” William heard Rukia give the order but he barely noticed because at that instant every forward gun on the Crusade fired and for every shot there was an amber line on the display, and Ross noted with grim pride that it was an almost solid wall of amber connecting his flagship to those three enemy vessels.

Space and time seemed to freeze for the three Mantisoran warships for an instant as an invisible force hammered at them, to the naked eye it seemed as though they simply began tearing apart for no reason as the anti-proton streams washed over their hulls causing massive warping in the materials until the hull plating contacted simply exploded in a ball of plasma.
To an observer using the special sensors that allowed the invisible energy weapons to be seen it was a very different spectacle as a massive wall of green energy enveloped the Mantiosran ships and began clawing at them with a fury unseen in any previous generation or on any prior warship.
The entire “battle” only lasted thirty seconds as the super monitor’s reactors let go and millions of tons of warship simply vanished in a glowing sphere of expanding energy leaving not even a scrap of wreckage. The monitor’s entire forward sections vanished leaving its aft end mangled and torn; the super dreadnought was reduced to a cloud of debris no larger then dust as 26 I-lasers punched through it like it was made of plastic; all of which happened without the Mantisorans even knowing what hit them.

“Are there any life pods?” Rukia asked, not actually expecting there to be any as she watched her displays in shock.
“No ma’am no life pods, or life signs.” A voice answered in tones of equal shock.

Even when a ship took a full broadside from a super dreadnought something was left unless the reactor’s went, but there were so many weapons locked on the three Mantisoran ships that almost nothing remained, even of the two who’s reactors never had a chance to go critical.

“Thirty-one thousand lives gone, just like that.” Ross said quietly as he turned away from the main plot and walked over to where Rukia was standing, “Helm, take us back to the rest of the fleet at full speed.” He patted the still stunned Commodore on her shoulder as he headed for the lift, and back to his quarters trying not to look the least bit nauseated by what he had just done in the blink of an eye.

Yeah I did bodge the DU density, what can I say. It was late and I got it wrong. Whoops.

Anyway where did you get that railgun length from, just curious that's all. I never did work out anything about them, they just did seem a nifty idea.

Finally as i was out by a 1,000 on the density of DU, ( ) you can cut the needed length of rail gun by the same amount to get the same energy from the slug. Or make them even slower but larger until you get a sensible length launcher.

Hey I don't use "dylithium crytals" or anything that "hand wavy"

For that matter I didn't put any "throw away lines" about projectiles in my story just telling you .

And for the most part I haven't mentioned anything "totally" unrealistic except maybe the shields but that's just subjective so you can't really just label mine "soft sci-fi" because you disagree with the one little bit about my shields and then turn around and say black holes being slung at people is 'hard' as that has to violate a whole lot more areas of physics then mine heh.

I didn't say you had put in any such lines, but it can be good to establish such facts before the action. It does look a bit Deus Ex Machina if during an attack the captain goes 'What are the chances? Those weapons do us no damage. That was lucky, we'd be dead otherwise.'

Before I start this is not personal. These points don't affect the story, it's science FICTION, making things up is the name of the game. I know what you're like, so take this in the spirit it's meant.

Flat out violations of physics in your story:

No those shields are not subjectively wrong, they're flat out impossible. You cannot magically kill an objects KE for less energy than the object has.

FTL, casuality and realtivity in the same universe don't work. At all. At the most basic level the paradoxes FTL would introduce are horrendous. Now as your opening warp points with happy abandon they aren't natural wormholes (which are 'just' local spacetime distortions and so sneak through) so that's a potential problem.

Admitedly you could be making wormholes, but that's highly dicey in and off itself. All you'd need is 'quantum foam' to open it and 'exotic matter' to produce 'negative energy' to hold it open. I'm not making those terms up the way (you couldn't ), they are hypothetical particle physics concepts. For instance 'exotic matter' is amazingly usefull stuff as it has negative mass, if it exists.

BUT if you had all the stuff that you'd need to do all that then you would be far in advance of the rest of the Icaran's general tech level. As in chucking black holes around advanced.

As your still working out what the I-lasers aresuspend judgment on them.

Oh and I'm pretty sure you have non-rotational artifical gravity, although I could be wrong on that one. I'm sure if I poked around I could find more, but I don't particularly want to I think that's enough to be going on with.

Ian Banks stuff however has a solid basis, it has however assumed that the hugely difficult has become possible, indeed easy. It doesn't violate any physics, it's immensly difficult, horribly expensive and requires horrendous ammounts of power. But it's not impossible and doesn't violate any physics we know.

Not knowing the details I can't comment on the throwing black holes, this is just based on his other stuff. However, off the top of my head, stupendous amounts of ultra dense material subjected to massive pressure would form a black hole. That's how they form in nature. Moving it around, well look at spinning black holes. The singularity inherits the angular momentum of the star it formed from. So just launch your large mass (3x a solar mass if your using self gravitation, less if your compressing it yourself) and as the mass races along and turns into a black hole it will inherit the momentum of the forming mass. So there you are, nothing in there violates any law of physics. But it ain't easy.

Three words Use Edit Button

Oh and this stuff is all now being discussed in the "General Tech Question" thread so as not to clog this one up with this kind of stuff
My shields as explained there are probobly a lot more reasonable.

Oh and I did get a kick out of "no offense because I know how you are" that right there is like saying "I hope this doesn't cause offense but your a jerkoff" lol get where I'm going with that?

[El_Phil]

You have been known to fly off the handle and take criticism badly. So I thought I'd pre-empt that.

I did read general tech questions, your shields are still utterly impossible. Also as the question was here, I responded where the question was.

I'm not editing that post, I stand by it.

[Starhawk]

Constructive criticism no [/i]nitpicking[/i] yeah a little bit.

Okay as I have stated it's sci-fi with a few thousand years more advanced tech then us so they may pull stuff against our knowledge of physics that's cool with me so if you really want to you can write a book taking note of every physical impossibility in my sci-fi universe if you want (still not all THAT many) -or- you can do that pesky little suspension of beleif deal that is very important to sci-fi and just read enjoy and maybe pass along the occasional correction to something that may be possible but that I got the "math" wrong on.

Now end of that so that I can actually have more story, because you may or may not have noticed I've added another chapter already today and want people reading that more than this

Oh and I meant edit button as in your double post so go ahead and stand by that if yah want lol

[El_Phil]

Two seperate points, no point combining them into one to confuse two seperate issues.

It was constructive post, you have learnt not to call that story hard sci-fi. I was happily suspending belief, then because of your posts I stopped and looked at it more closely. I wouldn't of bothered if you hadn't even mentioned the subject.
