L31[04:12:18] <SporkWitch> that's a whole
other level of pedantry, because they very much are controlled
explosions. it's not a continuous burn, it's a timed, short-lived
burn, more typically known as an explosion or detonation heh
L32[04:13:04] <SporkWitch> in the case of
diesel, it's even more appropriate, as if i recall correctly,
diesel actually uses the pressure itself to cauxse the combustion,
once it gets going

L89[13:41:07] <Althego> now that is
intersting
L90[13:41:20] <Althego> there are news of
laser comm experiments
L91[13:41:33] <Althego> but never for
actual usage
L92[13:41:48] <Althego> maybe spacex can
speed this up too
L93[13:44:51] <Mat2ch> Althego: with an EVA
suit
L94[13:45:00] <Mat2ch> which they seem to
develop from the IVA suit.
L95[13:45:09] <Althego> but spacex doesnt
have an eva suit. and the image shows the iva suit too
L96[13:45:09] <Mat2ch> Possibly 2-in-1-suit
then
L97[13:45:16] <Althego> interesting
L98[13:45:43] <Althego> and you think they
can develop a suit in less time that is the delay of nasa's new
suits?
L99[13:45:59] <Mat2ch> they are showing a
tether, probably with oxygen supply from it. So you need to make
the IVA suit only vacuum proof. Heat management is already built in
iirc
L100[13:46:51] <Althego> i think the iva
cable connects not only oxygen, but comm and cooling too
L101[13:46:56] <Mat2ch> jup
L102[13:47:13] <Mat2ch> not an independent
suit to walk around on other objects yet
L103[13:47:14] <Althego> so actually in
this case peole wouldnt be tourists
L104[13:47:16] <Althego> this is a
job
L105[13:47:21] <Althego> and not without
danger
L106[13:47:36] <Mat2ch> tbh going into
orbit is full of danger
L107[13:47:46] <Althego> that is
true
L108[13:47:53] <Mat2ch> even though SpaceX
has shown that they can handle it
L109[13:48:07] <Althego> but staying in
high orbit, and also doing a depressurization of the spacecraft
adds to that
L111[13:50:02] <Althego> a full suit would
still need a portable life support
L112[13:50:33] <Mat2ch> The
depressurization will be the most interesting part. Probably done
in a way they can deorbit in a short time, if something goes
wrong
L113[13:52:44] <Althego> probably not that
interesting. the lem could do it many times
L114[13:52:56] <Althego> it is losing only
a few cubic meters of air
L115[13:53:04] <Althego> if they let it
out
L116[13:53:11] <Althego> but i can even
imagine they just store it
L117[13:53:20] <Mat2ch> And about NASA vs
SpaceX. The NASA engineers tried to make a suit that matches 100 %
of their requirements. The SpaceX suit matches only 95 % (you can't
easily grab stuff from the ground with it).
L118[13:53:48] <Althego> but as spacex
does, they would improve it over time
L119[13:53:49] <Mat2ch> The solution here
is: Get a grabber.
L120[13:53:59] <Althego> just as they had
it during apollo

L211[19:14:19] <trace> Does our sun
revolve around the black hole in the center of our milky way?
L212[19:15:42] <darsie> kinda
L213[19:15:56] <Althego> you mean
orbits
L214[19:16:13] <trace> yes
L215[19:16:21] <darsie> It revolves around
the center of mass of the galaxy, which I guess is within the
SMBH.
L216[19:16:33] <darsie> orbits, yes.
L217[19:17:10] <darsie> It also orbits
everything within its orbit, which makes it orbit faster.
L218[19:17:36] <trace> what is different
about solar systems outside of galaxies
L219[19:17:47] <trace> do they have
different elements?
L220[19:18:05] <trace> because they would
need elements from dead stars
L221[19:18:12] <darsie> I guess the
metallicity is higher in galaxies.
L222[19:18:28] <Althego> stars dont really
need other elements than hydrogen
L223[19:18:36] <darsie> Humans do
L224[19:18:49] <darsie> rocks do
L225[19:18:53] <Althego> yes, solid
planets and life, etc, does
L226[19:19:03] <darsie> Life as we know
it.
L227[19:19:11] <Althego> jim
L228[19:19:15] <darsie> :)
L229[19:19:27] <trace> why
metallicity
L230[19:19:40] <darsie> Astronomers say
ever element >He is a metal.
L231[19:19:41] <Althego> astronomers call
everything not hydrogen an helium metals
L232[19:20:28] <trace> metallicity comes
from stars got nova?
L233[19:20:33] <UmbralRaptor> hydrogen:
chemical symbol X
L234[19:20:39] <UmbralRaptor> helium:
chemical symbol Y
L235[19:20:43] <UmbralRaptor> metal:
chemical symbol Z
L236[19:21:17] <UmbralRaptor> trace:
useful approximation, but also a fair number of elements are from
red giant stars
L237[19:22:17] <trace> which come from
star giants
L238[19:22:41] <UmbralRaptor> typically
carbon, nitrogen, and oxygen, but also when we get into trace
element land a lot of S-process ones
L239[19:22:44] <trace> which elements get
objects in galaxies and which planets of solar systems outside
galaxies
L240[19:22:51] <darsie> All elements
>Fe are from supernovae
L241[19:23:13] <Althego> but wasnt there
something about gold from neutron star mergers?
L242[19:23:32] <UmbralRaptor> darsie: It's
complicated(tm)
L243[19:23:34] <darsie> maybe
L244[19:23:37] <Althego> hehe
L245[19:23:53] <UmbralRaptor> Althego:
yeah, some elements are so you get arguments about there being
multiple r-processes IIRC
L246[19:24:10] *
UmbralRaptor also ignores the rp-processes because I know even less
about that
L247[19:24:17] <Althego> hehe
L248[19:24:27] <Althego> you sure know
more about it than us
L249[19:24:55] <trace> but there are
elements feasable from giant stars
L250[19:25:21] <darsie> I'm not sure what
the top elements from red giants are.
L251[19:25:48] <trace> so our sun does not
become a nova - what does it become
L252[19:26:03] <darsie> red giant
L253[19:26:13] <darsie> also nova <>
supernova
L254[19:26:22] <Althego> i think there is
some difference between nova and supernova
L255[19:26:29] <Althego> heh eyou are
faster again
L256[19:26:30] <trace> what is the
difference between nova and super nova
L257[19:27:11] <darsie> I think a nova is
when a white dwarf accretes matter from a companion star till
there's enough to start fusion on the surface.
L258[19:27:16] <UmbralRaptor> Our sun
-> red giant -> planetary nebula + white dwarf
L259[19:27:30] <Althego> there are also
several types of supernovas, one being the famous Ia that can be
used as a standard canfle
L260[19:27:36] <UmbralRaptor> darsie:
yeah, something something classical nova. IIRC it's a process that
can repeat a bunch of times
L261[19:27:53] <trace> what is planetary
nebula
L262[19:28:05] <darsie> Supernova is
gravitational collapse which starts fusion in the core which sends
a wave of fusion throughout the star, causing a huge
explosion.
L263[19:28:25] <Althego> UmbralRaptor: you
have to get you best ndg impressions for these :)
L264[19:28:29] <UmbralRaptor> A nebula
that early telescope astronomers (eg: Pierre Mechain, Charles
Messier) noted looked sort of like planets though clearly couldn't
be
L265[19:28:57] <UmbralRaptor> They're the
outer layers of sun-like stars that have since puffed off at the
end of the red giant phase
L266[19:29:36] <UmbralRaptor> They're lit
up mostly by being hot/excited gases in part from UV emission from
the white dwarf, and will expand and dispere over the next ~1e5
years IIRC
L267[19:30:27] <trace> I still do not
understand what is different about planets of stars outside a
galaxy to the ones inside galaxies
L268[19:31:09] <darsie> Planets outside
galaxies are probably mostly gas.
L269[19:31:17] <darsie> Due to less heavy
elements.
L270[19:31:26] <UmbralRaptor> Typical
examples would be eg: Ring Nebula, Cat's Eye Nebula, Helix Nebula,
and Dumbell Nebula
L271[19:31:44] <UmbralRaptor> darsie:
weirdly enough, we still find lots of seemingly rocky planets
around metal-poor stars
L272[19:31:52] <darsie> ok
L273[19:31:53] <UmbralRaptor> Gas giants
if anything are more common around metal-rich ones
L274[19:32:19] <Althego> there are some
rogue planets, maybe they catch those?
L275[19:32:50] <darsie> How disruptive is
ejection of stars from a galaxy for their planets?
L276[19:33:27] <darsie> Galaxy
collisions/mergers probably eject a lot of stellar systems.
L277[19:33:47] <UmbralRaptor> Insufficient
data to answer directly at this time, my understanding is not
particularly if some star in the disk gets thrown out as part of a
galaxy merger
L278[19:34:06] <UmbralRaptor> The
processes that cause runaway stars would be disruptive, but those
stars are unlikely to have planets anyway
L279[19:39:59] <trace> how does metal get
outside galaxies
L280[19:44:12] <UmbralRaptor> I'm unclear
on to what extent we have measurements of extragalactic gas clouds,
outside of some highish redshift stuff
L281[20:21:15] <SporkWitch> v-ger will
tell us in a few centuries :P

L289[22:03:14] <transhohmann> in theory, a
planet could get ejected from orbit
L290[22:03:36] <transhohmann> which makes
me wonder
L291[22:04:19] <darsie> They are on fixed
orbits in stock KSP.
L292[22:04:29] <transhohmann> yes, i
know
L293[22:04:59] <darsie> IIRC they would
get messed up relatively quickly in n-body physics.
L294[22:07:25] <transhohmann> I was just
thinking, could a planet be either knocked a bit off by some
massive event or just be in an orbit that will only last for a
relatively short amount of time, swing out of the system and later
be caught by either a different planet or star?
L295[22:08:44] <transhohmann> far-fetched,
but an interesting thought...if you didn't know this event had
happened you would assume some very strange things about the planet
and the star it was around if you were just discovering it
L296[22:09:51] <UmbralRaptor> Yes, though
in general ejection is far more likely than capture
L297[22:10:09] <UmbralRaptor> (Easiest
capture I think involves some weirdness with stellar close
encounters)
L298[22:12:17] <darsie> Most planets will
eventually get ejected from their stars, and most stars will get
ejected from their galaxy.
L300[22:13:54] <darsie> The end result is
that most objects (90% to 99%) are ejected from the galaxy, leaving
a small fraction (maybe 1% to 10%) which fall into the central
supermassive black hole.[5][14]
L301[22:16:56] *
UmbralRaptor is admittedly usually not considering times that
long
L302[22:17:37] <darsie> I made plans for
that time.
L303[22:20:06] <darsie> I thought of
leaving Milkomeda with a stabilized system of black dwarfs and eat
them with a black hole, living off the Hawking radiation.
