  1. Users with less than 3 posts and users who have received several warnings by moderators, IIRC.
  2. What does your pod look like? A simple pod with a 1.25m heatshield can survive pretty much any reentry.
  3. Even though I believe the announcement didn't really live to its hype, especially considering the few translated languages as of now (hope more will come, don't forget you have a bunch of people having nothing better to do than hang out here or crash rockets that will be willing to help bring KSP to their own language), I like the idea of the contest. I'll probably submit an entry if I don't forget in the meantime (I already know that if I do this seriously I'm so going to curse the 300 words limit, but whatever).
  4. Bon ben le jeu est pas traduit en français, donc on va avoir encore du boulot pour quelques versions on dirait.
  5. I'm down, but be warned this is either going to be 1984 or MadMax.
  6. A terrible one, that is. Having a pseudo-science subforum would literally be screaming: "come post all your conspiracy theories here and discuss them with people who think you are idiots and won't listen to anything you say even though that 1990s website by that random guy absolutely proves that the whole world is a lie".
  7. Of all the space programs to restart, the N1-L3 is probably the last one on the list. I can't imagine a single reason that would motivate anyone to dig this thing up. Anyway no. The 7K-L3 was designed for a lunar mission, all the other Soyuz were designed for LEO missions, you'd need a new design. Edit: the TMA is not used anymore, Roscosmos is using the updated MS for its ISS flights.
  8. That's the problem. As Steel said, external observations of the black hole as a whole suggest that it is only defined by its mass, charge and angular momentum. But in quantum physics you have information encoded in particles through superposition of states, according to general relativity this information is lost, which shouldn't be possible when looking at things at the quantum level. There are a few workarounds to make things not too bad, but we'll need a ToE for that one.
  9. We don't know. We do know that black holes have no hair which is a bit of a problem. As of now pretty much all theories on what information becomes inside a black hole violate a different bunch of quantum principles.
  10. Builded a plane ! Wings don't move unfortunately (Handles surprisingly nice for a plane that I built, not sure why. Also probably the first plane that I ever built that I find genuinely beautiful, maybe because it's based off one of my favorite IRL planes, but still: I'm making progress!)
  11. A wind tunnel to simulate missions in a game where you can create as many saves as you want, some of which with unlimited resources, have a cheats menu available, the ability to teleport wherever you want and can literally revert time? I'd say it's not necessary.
  12. TBH I haven't any news about GP2 in 2016, 2015 and 2014 either. It most likely won't happen. Either way, a new planet will be interesting for the time you need to get there and plant a few flags, after than it will become as bland as the other planets in the game. If you're not against mods, there are a few that add other planets (including gas giants) that can fill this place.
  13. The NERV don't have any thrust vectoring, so they will create some torque when firing if they are slightly off-centre without the ability to compensate for it, causing your ship to rotate. This is less of a problem in atmosphere because the torque created by off-centre engines is a lot weaker than your aerodynamic surfaces and they are able to compensate for this. But in space, you don't have air to push on so you can only rely on TWC, SAS or RCS. The above is pretty much a guess though: to be able to determine the exact cause of your problem, a screenshot of your craft would be very helpful. You can upload an image on an image hosting site such as Imgur and simply link it on the forums for us to see it (the forum doesn't support direct file attachements). And welcome to the fourms!
  14. You don't account for galactic orbit when transferring to stars. The Sun's galactic period is about 200 million years and it orbits at a few hundred km/s. Since the orbital are so big, the relative motions are small, and since the orbital velocity is very low for whatever would want to reach a star in a reasonable time, you can consider you're travelling in a straight line. Waiting for a transfer would take about one synodic period of the star you want to go to with the Sun. Very long orbit + very close orbits (relative to the size of the Milky Way) = gigantic synodic period. Putting in numbers, the smallest synodic period for the Sun and TRAPPIST-1 is 113 billion years (that's 8 times the age of the Universe). A Hohmann transfer would take roughly half an orbital period, or 125 million years. As for the dV, it depends on the time you want to wait to get there. Technically, escaping the Sun's attraction would be enough, so any rocket big enough to send a pod to Jupiter could do the job. Since we're considering straight lines, the dV is basically the maximal speed you want to reach for your trip (twice if you want to stop there).
  15. KSP mostly uses CPU. Unless you CPU is really good and your GPU is really bad, you're not limited by GPU.
  16. RA and declination are coordinates, they basically tell you where to look in the sky. So DMS units. Constellation is the constellation in which the system appears from our planet. Not a measurement so no unit. Apparent magnitudes are a log scale of luminosity of the star seen from Earth. The lower the apparent magnitude, the higher the luminosity. The letters stand for some standard astronomy filters which pick out different wavelengths of the spectrum. V is centred on visible, R on red, I J and K on different wavelengths in the infrared. Magnitudes are calculated using a log relation so they are dimensionless. Parallax a measure of the distance using the angle formed by the orbit of the Earth, the Sun and the star itself. Using perspective from the further stars in the background you can measure the apparent displacement of the star and therefore the angle. High school trigonometry converts this into a distance. I suppose "mas" stands for milli-arcseconds. Distance is the distance of the star to the Earth. Expressed in parsecs, a unit defined as the distance subtended by a 1° parallax, roughly 3.3ly. Mass is the mass of the star. Expressed in solar masses* (ratio to the mass of the Sun). Density is the mass density of the star. Expressed in solar densities* (ratio to the density of the Sun). Effective temperature is the temperature derived from the light spectrum of the star (stars are pretty decent blackbodies so they have a specific temperature associated with their light spectrum). Unit is the Kelvin (the true and only way to express temperatures). Luminosity is the luminosity (ie brightness) of the star. Expressed in solar luminosities* (ratio to the luminosity of the Sun). Metallicity, here, is the ratio of iron to hydrogen masses in the star. Ratio so no units. Age is the age of the star. Myr stands for Mega-year, or millions of years. * When you see a symbol with a dotted circle as subscript, it's relative to the Sun. If it's a crossed circle, it's relative to the Earth. You also can sometimes see subscript J, that is Jovian masses (usually used for gas giants). ESI is the Earth Similarity Index, a measure on how "close" an exoplanet is to the Earth, using its physical characteristics. IIRC it takes into account: mass, radius, surface gravity, equilibrium temperature and maybe other stuff.
  17. Who would have thought copy-pasting links could be so hard? Thanks for the nice words and for making me notice, and welcome to the forums!
  18. You know, you don't need online calculators. Special relativity is nice enough to simply scale every dilated or contracted parameter by the Lorentz factor, dividing or multiplying is just a matter of if you want a smaller or bigger number. Also, please don't use relativistic mass people, it confuses everyone and is not necessary for calculations, just add a γ in your formula and don't touch intrinsic parameters of particles.
  19. Shape? If your wildfire has a head, a body and several limbs and you see the same pattern in several places on the planet, you'll probably start to suspect something. I'd probably start by drawing the shape of their continents before drawing my species. Mirrors can be used to encode simple binary information (like morse), but yeah, communicating with another form of life that may be totally different from you might as well be impossible. Saying "hello" regularly would probably be enough to motivate people to push exploration further, and if no mass extinction occurs in a few centuries, sending a ship there would probably be the top priority of the guys in charge of your planet (whether or not your ship will contain nukes or an army is another debate).
  20. Giant fire signals in fields at night would be the most visible with limited technology. Big mirrors reflecting sunlight to communicate could also be a thing. Either way you'd have to make sure they are watching you with their own telescopes to see your signals. Getting actual communication would be quite hard though. A simple mathematical code would have the most chances of being deciphered without prior contact, enabling more efficient communications later on.
