02:42 <Webchat459> Can I extend the ship's future track length in Principia? I can see the Max History Length but can't find a Max Future Length or similar.

03:31 <queqiao-> ⟨S​oviet Onion⟩ Hmm, I wonder if we can truly model relativistic effects in KSP. At least gravitational, if not for time or length or other things

04:26 <queqiao-> ⟨Q​uadrupole⟩ Make the sun more oblate?

04:28 <raptop> I guess we could try spinning up the sun

13:57 <queqiao-> ⟨S​ir Mortimer⟩ @raptop fortunetelling

13:58 <raptop> That sort of name sounds like something egg would do

14:00 <queqiao-> ⟨S​oviet Onion⟩ hmm, I'm very much intrigued by raptop now

14:01 <raptop> ...how so?

14:02 <queqiao-> ⟨S​oviet Onion⟩ you are very intelligent, for one _(:_

14:04 <raptop> ❎ Doubt

14:07 <raptop> (I mean, quals were a huge struggle, as are the papers. And, well, my attempt at contributing to Principia was, uh, limited)

14:11 <queqiao-> ⟨S​ir Mortimer⟩ @raptop what would spinning up the sun do to relativistic effects of the mercury orbit?

14:11 <raptop> aaaaaaaaaaaaaaaa

14:12 <raptop> Given how wacky GR is, I half-expect it would mess with Mercuryś obliquity

14:12 <queqiao-> ⟨S​ir Mortimer⟩ Did i just poke a nest of wasps?

14:14 <raptop> I've seen occasional papers on arχiv that mention https://en.wikipedia.org/wiki/Lense%E2%80%93Thirring_precession and weird stuff happening (albeit typically with planets around Kerr blackholes or the like)

14:14 <queqiao-> ⟨S​ir Mortimer⟩ I'm just trying to wrap my head around how, if at all, the rotation of a body with a somewhat sane field of gravity (which I [in total ignorance of anything we might know about it] assume the sun is/has) would affect things in the vicinity of said body

14:15 <queqiao-> ⟨S​ir Mortimer⟩ But then again, astrophysics are notoriously hard to wrap ones head around.

14:15 <queqiao-> ⟨S​oviet Onion⟩ the space-time is obviously affected by the rotation, right?

14:16 <queqiao-> ⟨S​oviet Onion⟩ slight pulling in the direction of rotation

14:16 <queqiao-> ⟨S​ir Mortimer⟩ But how? would it... rotate?

14:16 <raptop> yeah, though I can't claim to understand frame-dragging beyond a layman's level

14:16 <queqiao-> ⟨S​oviet Onion⟩ rotate? not sure. But it will definitely get dragged around

14:17 <queqiao-> ⟨S​oviet Onion⟩ kinda like ergosphere, but to a much, much, lesser extent

14:17 <queqiao-> ⟨S​ir Mortimer⟩ I'm trying to picture some form of effect

14:17 <raptop> Like, my relativity class was like 1/3 Minkowsky solution, 1/3 Schwarzschild solution, 1/3 inclomplete FRLW solution

14:17 <queqiao-> ⟨S​ir Mortimer⟩ I'm trying to picture some form of corriolis effect (edited)

14:18 <raptop> Actually, we also got to see the 2-equation version of Maxwell's equations because hey, why not

14:18 <queqiao-> ⟨S​ir Mortimer⟩ *scrolls down on the wikipedia page, sees coriolis mentioned there*

14:18 <queqiao-> ⟨S​oviet Onion⟩ cool. My class didn''t go much into Minkowski though. Pretty much just some basic GR, then some cosmology

14:20 <queqiao-> ⟨S​oviet Onion⟩ hmm, relativistic n-body physics 👀

14:20 <raptop> Let's summon the scary stuff: grMHD

14:21 <queqiao-> ⟨S​oviet Onion⟩ 😟

19:19 <_whitenotifier> [Principia] ezshack starred Principia - https://git.io/JuSPU

20:16 <queqiao-> ⟨U​nboundedBirch8⟩ is the time to burn accurate on principia for burns that take place over mulitple stages

20:16 <queqiao-> ⟨A​l2Me6⟩ No.

20:20 <queqiao-> ⟨U​nboundedBirch8⟩ so how do i go about doing those types of maneuvers

20:20 <queqiao-> ⟨A​l2Me6⟩ (Principia doesn't understand stages at all, from what I understand, since it's a huge :rabbit_hole:... which is a little unfortunate.)

20:21 <queqiao-> ⟨A​l2Me6⟩ I try to design my stages to avoid them... otherwise, guess _a la_ stock maneuver planning? The stock burn indicator does show a burn time.

20:23 <queqiao-> ⟨U​nboundedBirch8⟩ so for your early lunar impactors what did you do

20:23 <queqiao-> ⟨U​nboundedBirch8⟩ my plan was to have an aerobee boosted by a gcrc

20:23 <queqiao-> ⟨p​Edro⟩ Use just an aerobee

20:24 <queqiao-> ⟨p​Edro⟩ XASR can push to the moon within 400kg

20:24 <queqiao-> ⟨U​nboundedBirch8⟩ alright thanks
