It's a good warning. I looked something up on the wiki and was like, "oh hot drat," because of an off-handed reference in the first paragraph.

I had a plot point of Knights of the Old Republic spoiled for me because I was browsing something that I thought was unrelated on Wookieepedia. Don't go to any fan wikis unless you're all caught up on something.

drewhead posted:In the books it is explained that rail gun rounds travel at a a speed that approaches C. So no, you're not going to see something coming at you at a speed that is indeterminate from that of light. Yeah, you can, through two avenues. One, the firing signature will be enormous. Every bit of kinetic energy carried by the projectile needs to be given to it by the launcher, which means the energy input is going to be roughly equivalent to the big boom when it impacts. Two, if it's moving arbitrarily close to c (which it might not be, but hell, let's go with it), the projectile's going to be forward-scattering gamma radiation off of whatever interplanetary dust or hydrogen atoms it's hitting on its way out. Those gammas will be moving *at* c, so you'd get some warning based on the speed difference. But really it's the first one. You might not see the bullet heading your way, but you'll sure see the muzzle flash from the gun that fired it. .

Going dark is as easy as turning your transponder off and not receiving or sending any emissions Barring magical stealth tech, you're going to be emitting IR and will show up like a flare. The Martian stealth tech is basically a magical method to prevent IR emissions. Everyone should read Stross's Iron Sunrise if you like the whole relativistic kill vehicle + space base planetbusting deterrent force thing.

Every bit of kinetic energy carried by the projectile needs to be given to it by the launcher, which means the energy input is going to be roughly equivalent to the big boom when it impacts. There was some “marines in space” series of books (I think it was a trilogy of trilogies, each covering a different time span). In one the early books the three super powers are the US, UN (really the EU, but this was written pre-EU I think) and China. There’s a low key shooting —well, I hesitate to call it an all out war— incident where the Chinese were attempting a sneak attack on a scientific outpost on Europa. Events are to the point were things are kicking off and a bunch of projectiles on a ballistic trajectory seemingly appear out of nowhere and take out the USN Battleship/Dreadnaught that’s providing orbital support. It hits like a shotgun blast. Shortly before the Chinese ship’s orbit had carried it to the other side of Europa. Turns out before everyone had hauled rear end out to this outpost, the Chinese had sent a task group out above the elliptical and then there were a bunch of very large fusion explosions that observers wrote off as weapons tests. But the Chinese had used the EM blanket created from that to disguise the firing of their rail guns so the projectiles would intersect on the probable orbital positions of the USN ship above the lab. Six months in the future. I always though that was one of the neatest depictions of how to conceal things like that. The Roci taking out the UN ship reminding me strongly of that.

So yea, technically I concede the point. Whatever fraction less than C that the round is actually traveling would be some delta difference of warning right?. I just took their description of being indistinguishable at face value. If one can't distinguish between those two speeds then can one really perceive between flash and boom?

I just took their description of being indistinguishable at face value. If one can't distinguish between those two speeds then can one really perceive between flash and boom? It can't be the same speed of c, it must be slower. It can be slower to an arbitrarily small degree, but there must be *some* finite interval between flash and boom, and yes, that interval would depend on on difference in speed times the range to the target. In the Expanse universe I think railguns fire at some some small percentage of c, at most. Firing projectiles at anywhere close to the speed of light would represent a level of tech that's far beyond the context of that universe. Like, the protomolecule could do it, but it's not the kind of thing humans in the Expanse can mount on battleships; a 1 kilogram mass traveling at .99c would have a kinetic energy of 5.4E17 joules, or in the ever-popular tons-of-TNT reference, a yield of 138 megatons. That's not the kind of thing that punches holes in an orbiting deterrence satellite which then explodes, that's the kind of thing that turns the whole thing into a rapidly expanding cloud of plasma the instant it makes contact.

Fister Roboto posted:Stable orbits don't. A massive explosion imparts new velocity vectors, and all it takes is a little nudge to degrade an orbit and set it on a reentry trajectory. If it was in Earth orbit, I'd say they'd probably burn up in the atmosphere, but Mars doesn't really have much of that. Deimos is tiny and insignificant, and the only real reason people are upset is at the principle of losing a moon (and a small military base).

Yeah even outside of the sci-fi sphere I'm a real sucker for military plans that are months in the making or that involve elaborate concealment of what you're up to. There are of course numerous actual historical cases of insane battle plans as well, where even when the loss of life sucks to think about the strategy can be really interesting.

Well Antarctica might have mineral deposits worth going after, and depending on what climate change did to the region, it may be more inhabitable than you're thinking in the post-climate change world of the Expanse.

In the opening credits, we see the statue of liberty being put behind a sea wall, and when Bobby goes to see the ocean she's essentially sitting in front of one as well. Think it's safe to say that Antarctica is fairly habitable in this timeline.

There is a space manoeuvre in the Startide Rising, where the dolphins dump a load of water in their wake for a flotilla of chasing galactic fanatics to run into at near c. I really enjoyed 5 of the uplift books, The Uplift War is as good an example of Planetary Romance that you will find. Brightness Reef (is it just the first half?) is as bad as TUW is good but it is worth slogging through as the two after that are A grade for multiple  galaxy spanning grand space opera. I must dig out my copies for a reread...Phoneposting.
